FOLDED Corruption
I entered FOLDED, a game pitched as a large scale social experiment and art project hosted by @Bandors, with excitement and curiosity. A minimalist concept: check in once per day or be eliminated. Sounds simple, fair, and like a fun endurance challenge, right?
Well, that illusion did not last long.
One player, @retr0id, has been exploiting the system using scripts to check in automatically, bypassing the very premise of human endurance and commitment the game supposedly tests. That alone bends the spirit of the game. But it gets worse.
As a protest, I made my password public, a form of self sabotage and social experiment in itself to test the communities ethics. In response, @retr0id took control of my account, logging in and out every 30 seconds to sabotage my ability to check in. I had to set up a defense system just to stop getting kicked off my own session, ridiculous for something that is supposedly about routine and patience.
I reported this harassment to the host. The response?
Shenanigans are valid and encouraged
So automated check ins and harassment via account hijacking are valid. But here is the kicker: voicing protest in the comments was considered unacceptable. For speaking out, I was blocked by the host. I can still play, technically, but I cannot comment or communicate, silenced without recourse.
To make matters worse, I had thousands of mana on the line, with bonus prizes promised for finishing 10th, 5th, 3rd, and of course for winning. Entry alone cost 2000 mana, a substantial fee by Manifold standards. When I asked @Bandors to reset my password and even offered 50 mana for the trouble, I was told it was too hard to change. A simple password reset in a game about endurance, too hard.
FOLDED has devolved from a game of patience into a tech savvy popularity contest where
Coding trumps commitment
Harassment is brushed off as shenanigans
And dissent gets you shadowbanned
If this is performance art, then the message is clear
Cheat smart. Stay quiet. Do not challenge power.
If this is a psychological experiment, then congratulations, you have recreated 1984. The winner will not be the most disciplined, but the one most willing to manipulate the system unchecked.
If that is the art you want to create, fine
But do not pretend it is still a game.Active 3 months ago

I am the president. I am @realDonaldTrump.
You know, they said it couldn’t be done. They said we couldn’t turn things around. But we did. We did it before, and we’re going to do it again — bigger, better, and stronger than ever before.
We had the greatest economy in the history of the world. Everyone was winning — jobs were up, taxes were down, the border was secure, and America was respected again. Countries all over the world respected us. They didn’t laugh at us. They didn’t take advantage of us. We made great deals. Tremendous deals.
Then — disaster. Total disaster. Crooked politicians, weak leadership, chaos at the border, inflation like we’ve never seen before. Energy prices through the roof. Crime in our cities. They don’t know what they’re doing. Or maybe they do — maybe it’s on purpose.
But we’re not going to let them destroy this country. We’re bringing it back.
We’re going to drill, baby, drill. We’re going to bring manufacturing home. We’re going to protect our farmers, our truckers, our incredible police, and our beautiful, wonderful veterans — the best people anywhere in the world.
We will stop the invasion at the southern border. We will end the crime wave. We will defend your Second Amendment, your First Amendment — all of them. We will stand up to China, we will bring jobs back from China, and we will put America First. Always.

AI Safety Research Futarchy: Using Prediction Markets to Choose Research Projects for MARS
Summary
Geodesic is going to use prediction markets to select their projects for MARS 4.0 and we need your help to make the markets run efficiently! Please read through the proposals, and then trade on the markets for the proposals you think might succeed or fail. We intend to choose the best proposals in two weeks!
Full proposals are in Google doc linked below, links to markets are in the section "The Projects".
Google Doc (similar content to this post + full proposal overviews).
LessWrong post (similar content to this post).
Introduction
Geodesic is a new AI safety startup focused on research that is impactful for short AGI/ASI timelines. As part of this, we are committed to mentoring several projects as part of the Mentorship for Alignment Research Students program (MARS), run by the Cambridge AI Safety Hub (CAISH).
We are also excited about new ways to choose and fund research that reflect the aggregated perspectives of our team and the broader community. One way of doing this is using conditional prediction markets, also known as Futarchy, where people bet on the outcomes of taking various actions so that the predicted-best action can be taken.
We believe a system similar to this might be really useful for deciding on future research proposals, agendas, and grants. Good rationalists test their beliefs, and as such, we are doing a live-fire test to see if the theory works in practice.
We are going to apply this to select research projects for MARS 4.0, an AI safety upskilling program like MATS or SPAR, based in Cambridge UK. We have drafted a number of research proposals, and want the community to bet on how likely good outcomes are for each project (conditional on being selected). We will then choose the projects which are predicted to do best.
To our knowledge, this is the first time Futarchy will be publicly used to decide on concrete research projects.
Futarchy
For those familiar with Futarchy / decision markets, feel free to skip this section. Otherwise, we will do our best to explain how it works.
When you want to make a decision with Futarchy, you first need a finite set of possible actions to be taken, and a success metric, whose true value will be known about at some point in the future. Then, for each action, a prediction market is created to try and predict the future value of the success metric given that decision is taken. At some fixed time, the action with the highest predicted success is chosen, and all trades on the other markets are reverted. When the actual value of the success metric is finally known, the market for the chosen action is resolved, and those who predicted correctly are rewarded for their insights. This creates an incentive structure that rewards people who have good information or insights to trade on the markets, improving the predictions for taking each action, and overall causing you to make the decision that the pool of traders thinks will be best.
As a concrete example, consider a company deciding whether or not to fire a CEO, and using the stock price one year after the decision as the success metric. Two markets would be created, one predicting the stock price if they're fired, and one predicting the stock price if they're kept on. Then, whichever one is trading higher at decision time is used to make the decision.
For those interested in further reading about Futarchy, Robin Hanson has written extensively about it. Some examples include its foundations and motivation, speculation about when and where it might be useful, and why it can be important to let the market decide.
The Metrics
Unlike stock prices of a company, there's no clear single metric by which research can be judged. Because of this, we've decided on a small selection of binary outcomes that will each be predicted separately, and then we will use their average in order to make the final decisions. We're not claiming these are the best metrics to judge a research project by, but we think they will be appropriate for the MARS program and sufficient for this experiment. The outcomes are:
A LessWrong post is produced within 6 months and gains 50 upvotes or more within a month of posting.
If a LessWrong post is produced, it gains 150 upvotes or more within a month of posting.
A paper is produced and uploaded to arXiv within 9 months.
If a paper is produced, it is accepted to a top ML conference (ICLR, ICML, or NeurIPS) within 6 months of being uploaded to arXiv.
If a paper is produced, it receives 10 citations or more within one year of being uploaded to arXiv.
Clarifications:
Unless otherwise stated, timeframes are given from when the research begins, i.e. the start of the MARS program
Updates to posts and papers will be considered the same entity as the original for purposes of outcome resolution (i.e. If a paper is produced and uploaded to arXiv within 9 months, but it is edited after this before being accepted at a conference, (4) still resolves YES)
Some outcomes are conditional on others as follows: outcome (2) will resolve N/A if (1) resolves NO, outcomes (4)-(6) will resolve N/A if (3) resolves NO
The Projects
There are 3 groups of proposals, and from within each group we will choose the single predicted-best project. The groupings represent the mentors for that project. To read through each of the proposals and the bios for each mentor, please see the Google doc. Currently we plan to close the markets and choose the projects on Monday the 12th of October. Below we provide a quick overview of each and link to its respective prediction market.
Group 1: Cameron Tice
Goal Crystallisation: Investigating whether AI models that fake alignment perfectly during training retain their original goals or have them changed despite following through with deceptive alignment.
Post-training order and CoT Monitorability: Examining whether different post-training orders (applying RLHF after reasoning training) affect models' tendency to obfuscate deceptive reasoning in their chain-of-thought outputs.
Online Learning for Research Sabotage Mitigation: Attempting to use online learning to train AI systems away from research sabotage by creating deliberately underperforming model organisms and applying RL to try and improve their research performance.
Group 2: Puria Radmard & Shi Feng
Salient features of self-models: Testing whether LLMs have genuine self-models or just recognize stylistic patterns by examining if self-recognition training generalizes across different types of content.
Exploring more metacognitive capabilities of LLMs: Investigating whether LLMs can metacognitively monitor their own internal probability distributions and predictive models, with implications for deceptive alignment and AI safety.
Group 3: Lennie Wells
Model organisms resisting generalisation: Testing whether AI models learn the distribution of tasks under which humans have good oversight, and resist generalisation beyond this distribution.
Detection game: Running a ‘detection game’ to investigate how we can best prompt trusted monitors to detect research sabotage.
Research sabotage dataset: Creating a public dataset of tasks reflecting current and future AI safety research that can be used to study underelicitation and sandbagging.
Model Emulation: Can we use LLMs to predict other LLM’s capabilities?
Go trade!
We hope to use prediction markets to effectively choose which research projects we should pursue, as well as conducting a fun experiment on the effectiveness of Futarchy for real-world decision making. The incentive structure of a prediction market motivates those who have good research taste or insights to implicitly share with us their beliefs and knowledge, helping us make the best decision possible. That said, anyone is free to join in and trade, and the more people who do the better the markets perform. So we need your help! Please read through the proposals and vote on the markets, be a part of history by partaking in this experiment!Active 23 days ago
Leagues market creator updates
1) Profits and losses from trading on your own markets no longer count towards your league's earnings. This was to reduce the number of people winning their leagues by creating a new market with significant liquidity and correcting the probability from the initial 50%.
2) Unique trader bonuses are back for leagues! Any unique trader bonuses gained from a new trader betting on your market since the season start date will count. However, to keep things fair, we will check if the market was created within the last 31 days of the bonus and only count those that are. This keeps market creation more in line with the rules of trades having to be within the given month; however, it doesn't create weird incentives of waiting to create your market.Active 7 hours ago

Manifold Game Show Idea
I want to make a sort of game show here on Manifold where 2 contestants and the game show host each put up a blind into a bounty market pot.
The 2 contestants are put into a Prisoners' Dilemma situation where they can either share the pot 50-50, or try to steal it all. If they both try to steal, the host gets the pot.
Contestants would be accepted on to the show if they have a similar RISK rating, using the @crowlsyong RISK Credit Score system as an ELO rating.
A market is made for each contestant, allowing the public to bet on if they will share the pot, steal it, or walk away and forfeit it (ie take no action by the deadline).
Contestants are encouraged to make backroom deals with anybody from the public to encourage manipulation on those markets. Or, they can bluff about making back room deals. Who's to say?

Handling markets while the creator deliberates
Goal: Discussion
What's the best thing for a creator to do while they deliberate something about their market? How can the site help them do this while maintaining a fair trading environment?
Application
Any time a creator is faced with making a choice about their market. It can be: choosing whether to resolve it, whether something 'counts' in the market, tweaks to the rules, or dealing with surprising things that are not in the criteria.
Problem
If the creator leaves trading open while they are unsure how to rule, traders often start trading on "What will the creator decide" rather than "What will happen in the future". This type of trading can sometimes eclipse trading on the actual question at hand, and it can also influence the creator's decision-making process.
Current options
There are several strategies creators have used over the years, they seem to all have some upside and some downside.
Leave trading open: Make multiple comments and be open about your thought process. Traders respond to every comment. You do get the benefit of instant response to your ideas, but traders may feel misled if your initial comments do not line up with your final decision. The most common pitfall is creators frequently issue contradictory clarifications.
Leave trading open but don't comment: Just let everyone battle it out while you deliberate, and don't post about it until you've come to a decision. This prevents the creator from making multiple contradictory responses, but can leave traders just as upset if the final ruling is not in line with the way they read the criteria. For "Will X happen before Y"-type markets, if the creator does not respond to questions about whether event Z 'counts', the traders often eventually decide that no, Z did not count, even if the creator never issued a ruling about it.
Trade on it yourself: Sometimes creators who do trade on their own markets start trading when things are in question. Maybe that reveals their own thoughts?
Close trading pending decision: It is not obvious to a new creator, but they have the power to close trading at any time using the same window where they can change the closing time. By closing trading before initiating discussion, the creator can avoid disgruntled traders who were influenced by thinking-in-progress. There are some downsides: Reopening the market is tricky because there is often a price delta pre- and post-closing. Who gets to 'steal' that liquidity? What if the creator is not around fast enough to close trading and a bunch of people already made trades about "What will the creator decide"? There is also an awkward interplay with league scoring here once every month.
Discussion topic
So, is this really a problem that needs solving? Is it okay how it is? Should we be looking at better options here?
Here are a few possible 'helps' for the situation, not necessarily solutions:
Better UI/guidance for creators in this situation -- the site could give them advice on avoiding common problems.
More sophisticated close/reopen mechanism -- there have been several suggestions for a more fair market reopening procedure, including 'auctions'
Provisional trading mode -- let people trade while the market is in limbo, or some new 'not-quite-closed' mode, but those trades will all be N/A'd if the creator decides that it resolved at the time they closed it earlier
Yank the liquidity -- maybe "closing a market" is actually just removing the creator's liquidity, but traders can still trade with limit orders. The creator is usually the one putting up all the juice, let them withdraw all but 1 mana or something, until they've ruled, and then let them put the market back live with fresh liquidity at the price they think it should be at. Traders can still trade in the interim if they wish.
Got any additional good ideas? Maybe you think this is a huge nothingburger and not a big deal. I don't think this is the #1 problem facing the site, but could be a fun discussion.Active 15 days ago

Courtesy of informing in advance and/or announcing withdrawal of significant liquidity?
I know for myself that being informed that liquidity has been withdrawn from a market affects my trading, so it would be a courtesy to be as aware as possible of actions in that regard, in my view. I can understand that there is no natural incentive to do so, but it would be nice. Certainly being above board about it would improve the taste in ones mouth, when encountering it.

Frequent Market Terms' Recommended Definitions
[WORK IN PROGRESS] You are more than welcome to contribute in the comments by asking for words to be added, or proposing definitions / workshopping current defs.
announces
(by an org / company / group, of a product): The entity, or an official representative or partner, makes an official public statement about the product, beyond vague references / hints / teasers.
(by an person, of a statement or fact): The person says the statement or fact in a publicly verifiable way. eg. "Will Elon Musk announce he doesn't plan to have more children in 2025"
releases
(by an entity, of a product): The entity makes the product accessible to members of the public in at least some region. This excludes a closed beta.
by [time]. Warning: If timezone differences may be material to the resolution, they must be specified.
by [specific moment]: The event must have happened before that specific moment. eg. by March 23, 11:59 PM ET. A useful way to specify a moment is to say "start of [date range]" (eg. by start of 2026) or "end of [date range]" (eg. by EOY 2025).
by [day]: We recommend not using this term (use "before" or "in" instead). Meaning must be inferred from likely intend of market creator. eg. usually, "by March 31" == "Before April" == "by April 1st"
by [year]: We recommend not using this term. The market's "close time" may indicate what the market creator intended.
before [date range]
The event must have happened before the start of the date range.
in [date range]
The event must happen between the start and end of the date range.
win
(Of a professional cycling race or stage): Defaults to the winner declared on the day at the podium celebration after the race. Later disqualification or alteration of the results (the same day, next day, or any time in the future) would not change the resolution.
AGI (or Artificial General Intelligence)
a totally unserious term whose use should result in the market being unranked and treated as a meme market

This is a creative version of shark tank but for manifold markets.

By investing, you would mangram them based on the deal, and the rest is up to the others. This should be a resource, and I will take it down if people get scammed.

My Two Ideas: An Open letter to Manifold Devs
Subject: Two Feature Suggestions to Improve Manifold
Hi Manifold team,
I'm a frequent user and a big fan of the platform — thanks for building such a unique and engaging experience.
I wanted to offer two feature suggestions that I think would make Manifold even more useful for strategic and active traders:
1. Conditional Buy Orders ("Buy when it hits X%")
Right now, limit orders don’t allow users to express conditional intent cleanly — if I try to “buy at 95%,” but the market is currently at 70%, the system sees that as above market price and fills the order immediately, which defeats the point. What’s really needed is a new kind of order that only triggers when the market reaches or exceeds a certain probability — effectively a “stop” or “conditional” order.
This would let users automate reactions to late-breaking information (e.g. betting once a candidate wins a primary or once a sports team is clearly winning), without having to camp on the page.
2. Options for Highly Liquid Markets
For markets with high liquidity (e.g., over 100,000 M), I’d love to see even basic options added — for example, “YES if the market is above 60% on July 1.” These kinds of instruments would allow for more nuanced bets, hedging, and leverage strategies — and they’d be especially fun in politics, crypto, or major sports events where the market dynamics are rich and evolving.
Thanks again for all the work you're doing — the platform has grown into something amazing, and I’m excited to see where you take it next.
Best,

Governing Ourselves: A Blueprint for Manifold Futarchy
Governing Ourselves: A Blueprint for Manifold Futarchy
When @bens suggested a Manifold Government, many users worried that it would become an oligarchy, an elite club, old-timers and whales calling all the shots. Futarchy lets us avoid that.
A veteran's reputation doesn't carry more weight than a newcomer. Decisions get made based on what will actually produce the best outcomes, because everyone has financial incentives to identify the policies that will truly work.
How It Works First, we agree on our values (see roadmap below); what we want the government to achieve. For example: fair resolutions for subjective markets.
Imagine someone creates a market: "Will AI be friendly in 2026?" It has no resolution criteria and the creator is inactive. We don't argue endlessly in comments. Instead, we let the market guide us:
People propose resolution criteria, like:
Proposal 1: "Resolve based on a poll of 10 recognized AI safety researchers."
Proposal 2: "Resolve YES if no one is killed by AI in 2026."
We open prediction markets:
"What will the satisfaction score on resolution criteria be if we adopt Proposal 1?"
"What will the score be if we adopt Proposal 2?"
The proposal with the higher forecasted satisfaction wins. Everyone can bet; decisions are made based on expected value, not those with reputation, loud voices, account age or manna.
Tentative Roadmap
Legitimacy Vote (simple headcount): We need to decide whether to pursue this through Ben's constitutional convention or with our own poll asking "Should we explore Manifold futarchy governance?" Either path needs 60%+ support to proceed.
Values Survey (simple headcount): Multiple choice poll (with user additions open) on core values - any option getting 50%+ makes our official goals list. Anything at this stage (e.g. consolidating 2 goals into one) is voted on in a poll with a simple headcount.
Constitutional Convention: Elect 7-11 drafters via approval voting to write our constitution. The constitution should include 3 articles.
Our values as decided by stage 2
Inalienable rights (e.g. Active market creators retain full control of their markets - barring mod actions)
Mechanisms and Processes: Weighting of the Futarchy Meta-Index, when are polls created, minimum volume / liquidity on decision markets etc.
Public Drafting Period: 2-3 weeks of open drafting with community input
Constitution Ratification (simple headcount): Final up/down vote - needs 67% to pass
We elect The Stewards: our initial moderation team through a process the community defines, potentially using Futarchy forecasts about their future performance.
We build the basic infrastructure (posts page, dashboard, market templates) to run prediction markets on government decisions.
Example Goals (from @crowlsyong Constitution draft)
Establish fair resolution criteria for subjective markets
Provide advice for controversial markets
Manage a community treasury (liquidity, prizes, bailouts)
Award meaningful honors like Market of the Month
The Hybrid Model We combine quick community feedback with longer-term metrics to guide both immediate and lasting success:
Weekly Pulse: Each goal will have its own satisfaction metric and poll, so we can measure how well we're meeting specific objectives. For example, a poll on whether we're establishing fair resolution criteria for subjective markets. This provides fast community feedback.
Futarchy Meta-Index: A composite of (for example):
Community Satisfaction (40%)
Resolution Quality (20%)
Treasury Impact (20%)
Engagement Growth (20%)
Example Decision Process Every policy triggers prediction markets with fixed timing:
Proposal Window: First week of each month
Market Period: 1 week of betting on "What will the Futarchy Meta-Index be if we adopt this?" vs. "What will it be if we don't?"
Decision: Automatic implementation based on higher predicted outcome
Satisfaction Polling: 1 week after implementation
(Might not need the following due to the hardworking mods)
Enforcement: The Stewards A small team - The Stewards - keeps the system clean, preventing spam and low-quality proposals. But they're accountable too: if markets forecast that replacing them would improve our metrics, they're replaced automatically. No entrenched bureaucracy, just forecasts and outcomes.
This is governance designed for a people that believes in prediction markets. It rewards what works, not the landed gentry.

Keep giving market creators more tools
Continuing in my theme of pleading for better support for question creators:
I know some of the meta around question creation and management is still stuck in the mindset from past iterations of the site. For example, we used to have creators 'assuming' that they would 'profit' (directly) from creating questions in the form of Manifold handouts for attracting bettors. Some of that has died out, but some of it still remains.
I think the site still has not fully internalized the degree of change we went through when we fell away from "keep subsidizing the AMM every time someone new trades" to "functionally all markets are fully subsidized by only the creator".
If I am subsidizing the market completely on my own, I should have immense power over the application of the liquidity in the market. The site should directly give me the tools I need to get the most out of my capital in managing questions. When Manifold supplied the majority of liquidity in most markets, this did not make as much sense, but I feel like creators are not given enough power to manage their markets right now.
Some summary points that could each be elaborated on request if they are not clear to others:
Creating a question should not 'feel' like 'spending' the full amount of liquidity chosen. The default assumption should be that you will only 'pay' the amount that your current/initial guess differs from the current consensus.
Creators should be directly encouraged to set up a market with their best guess of the probability to be as efficient as possible with liquidity.
'Paying' directly for a notification that news has happened is fine, but creators who specifically know that news is on the horizon should be able to opt out of paying for news updates by withdrawing liquidity before the expected news (and re-applying it afterward if appropriate).
Creators should probably be able to fine-tune their liquidity application without affecting their 'profit' on a market. If I know a market should be at 71%, I should be encouraged to set it up at 71%, but the site currently wants me to set it up at 50% then trade/profit by moving it to 71%, which wastes capital and generates questionable 'profit'.
I should be able to schedule the withdrawal (and possibly addition) of liquidity in advance.
"The market is open for trading but there is very little liquidity" is much better than "I am closing the market before an expected crux moment because the platform does not let me withdraw liquidity"
Reopening a market for trading after the above point is a miserable experience and feels close to fraud even if you warn traders in advance. Anything to help with this situation would be appreciated.
In more complex market types like multiple choice, I should have direct control over how much is in the pool on each option. Sometimes one option is very important while another is not important at all.Active a month ago
Coding Agent Capabilities at EOY 2026.
The length of programming tasks OpenAI's reasoning models have been capable of has been doubling every three months. This is likely to continue until the scaling of reasoning models hits the compute ceiling, likely sometime in 2026, at which point the doubling-time may revert to something just a little better than the previously-observed doubling time of 7 months.
The period of time between the release of o3 and when we expect the 3-month doubling period to end is 13 months. This entials 13/3 = 4 1/3 doublings, which would get us to 1935 minutes, or 32.25 hours. We can then expect one more double, to 64.5 hours.
So, by EOY 2026 I expect we'll have coding agents that can do the sorts of things that would take a skilled human engineer a week of total focus to accomplish. Should be fun!Active 4 months ago

I have now decided to go back into the labor force due to my currently limited options in life. I am on clozapine, which is a sedative that makes me less extraverted and I suspect reduces my conscientiousness.
I have an IQ of roughly 125 and a bachelor's degree in economics and reside in a major metropolitan area. I know a bit of JavaScript/Python. I had very little success in finding a job after college by posting online applications, but I did work a bit part time. I would like to find full time work by the end of the year.

Idea for calibration scores
Manifold used to have personal calibration scores for each users. It was deemed unnecessary, because you can track how well a user is doing by their profit. But profit isn't a pure measure of accuracy, because some people use the site more than others, some people buy mana, etc.
But as some users have pointed out, the previous calibration metric, the Brier score, isn't much better. To demonstrate why, imagine a user, CoinFlipper, who doesn't even read the title/description of any market. He just looks at the current probability P. Using a random device, he will bet YES with a probability of P and will bet NO with a probability of 1 - P. Assuming that the markets on Manifold do not consistently overestimate or underestimate probabilities, CoinFlipper will eventually end up with a near-perfect Brier score. Even if Manifold does consistently overestimate/underestimate probabilities, it would be easy for CoinFlipper to measure that and factor it in to his random bets.
Obviously this is an issue, because you shouldn't be able to get a good calibration unless you're providing valuable information to the market. So here's a different calibration metric I thought of.
Start off by separating users into those who have positive profit and those who have negative profit. Let's call those with negative profit "Rank 0 (R0)" and positive profit "Rank 1 (R1)". People in R1 are the users who are providing valuable insight to Manifold.
Next, we need to compare how R1 users fare against each other. To do that, calculate each user's "R1 profit". The R1 profit is basically a user's weighted profit, with higher weights given to bets made against other R1 users. For example, let's say you bet 100M on YES, and win 1000M. If 20% of the NO shares were held by R1 users, then 1000M * 20% = 200M is added to your R1 profit. If 0% were R1 users, then nothing gets added to your R1 profit. The reasoning here is that you were betting against R0 users, so winning against them doesn't mean anything. The same calculations are applied if you make a loss (instead of a profit).
Finally, we look at the users who have a positive R1 profit. These users are now called R2 users. We repeat the entire measurement on R2 users to figure out who the R3 users are, and so on. Eventually we would have to stop at, say, R10, because there wouldn't be enough bets between R10 users to make a proper assessment.
You could show the user his/her calibration score as just the rank, or you could convert it to a percentile score.
I don't know if this metric is already well-known, but I think it would be cool if this was added to Manifold (though I imagine it would be a hassle to implement). Anyways, let me know if any of you have feedback.Active 18 days ago

Prediction Market Thoughts part 3: The Holy Trinity of Bots
# Prediction Market Thoughts part 3: The Holy Trinity of Bots
I previously posted my thoughts on [backend](https://thequantummilkman.substack.com/p/my-thoughts-on-prediction-market) and [frontend](https://thequantummilkman.substack.com/p/my-thoughts-on-prediction-markets) features I'd like to see in prediction markets. This post will cover my thoughts on bots.
## The three types of bot participation in prediction markets
This post is partially inspired by Ozzie Gooen's post [here](https://forum.effectivealtruism.org/posts/pLkFmWP3xmGG8YvjP/ai-for-resolving-forecasting-questions-an-early-exploration) on using bots to resolve questions. This is a cool post, but I feel like it's only one part of the puzzle. In my mind, there are three main types of bots that could be useful in prediction markets:
1. Question Creation Bots. These bots define resolution criteria for markets.
2. Trading Bots. Bots that make trades.
3. Question Resolution Bots. Bots that resolve questions, as Gooen discusses.
I feel strongly not just that each of these avenues for bots is underexplored, but that having all three types together in a single ecosystem realizes some important synergies:
* Scale: A theme of this blog is that [prediction markets are information-theoretical constructs with the ability to learn](https://thequantummilkman.substack.com/p/prediction-markets-eat-bayes). But learning requires lots of data to learn from, which means lots of markets and predictions. If we can have prediction market platform that functions end-to-end without human intervention, we can potentially get to a new level of scale.
* Inconsistency: Bot-generated market can be uninteresting or ambiguous, and bot resolutions can be incorrect, which makes these markets unappealing to humans. But bot traders don't care about this type of friction and can potentially learn to adjust to it better than humans can.
* Retrodiction: If an LLM has a data-cutoff date, we have good reason to believe a bot based on that LLM would not have any special advantage in predicting events after that date. Similarly, that any markets proposed by such a bot would not, by their existence on the platform, offer predictive power. This leads to the intriguing possiblity of letting a variety of such bots compete in a retrospective simulation of a prediction market over a period of years before the present, where the bots in the market are gradually fed news from news sources one date at a time.
To paint with a broad brush: Systems optimized for machines are different from systems optimized for humans, so we should explore what a reorientation of the prediction market ecosystem would look like as a radical change of design space.
<!-- This isn't to rule out human involvement in prediction platforms that orient towards bots - I think a human factor could help to keep things on track. Of course, there's also a balancing act to be played, since if the AI generated markets are too "sloppy", humans won't want to participate. Hopefully a happy medium can be reached where humans who don't mind LLM-speak can surface the best written markets for the rest of the community. -->
## Question Creation Bot Idea
Manifold already offers AI assistance in creating markets, but this usually starts with human prompting. What could a more autonomous market creation engine look like?
Most prediction markets pertain to events covered in the news. Consider a bot that works on something like the following prompts:
> You are a master prediction market creator. It is your job to create prediction markets that are interesting, have clear resolution criteria, and which are relevant to events in the news. Today, you will be creating a title for a prediction market based on the following news article.
>
> Insert news article here.
>
> Please brainstorm a future event that might or might not come to pass relevant to the content of this article. Here are some examples of the types of events you might track, based on previous articles
>
> Insert zero-shot examples
>
> All the information relevant to decide if the market has resolved yes or no should be publicly available by Date.
>
> Here is a title and date for a prospective prediction market.
>
> Title and date
>
> Now please write resolution criteria for the market you have just titled. The resolution should be clear and unambiguous: Anyone who is familiar with the events in question after the resolution date should be able to agree on how the market should resolve. Please also include a list of URL sources that could be accessed on the resolution date that could be used to resolve the market.
## Trading Bot Ideas
There is a nice post [here](https://www.alignmentforum.org/posts/uGkRcHqatmPkvpGLq/contra-papers-claiming-superhuman-ai-forecasting) that criticizes [some](https://arxiv.org/pdf/2402.19379) [prior](https://arxiv.org/pdf/2402.18563) [literature](https://drive.google.com/file/d/1Tc_xY1NM-US4mZ4OpzxrpTudyo1W4KsE/view) [on AI forecasting](https://www.arxiv.org/pdf/2408.12036). As far as I can tell, the forecasting bots in these articles all work by a straightforward RAG pipeline where they request news articles from a search engine and then are prompted to base a prediction off of the articles.
The post highlights three things that the AIs have problems with \footnote{and a fourth way which just creates noise, namely data leakage}:
* The AI fails to find up-to-date information on the questions
* The AI finds only low-quality information on the questions
* The AI lacks high-quality quantitative reasoning
Given the architecture of the bots in question, these problems seem pretty unsurprising. But perhaps this leaves the door open for more sophisticated bots that work better.
In particular, I notice that many of the strategies I personally use to trade are amenable to replication by a bot, but probably not by a bot of the type described above. So consider this section my alpha dump.
### Using price data from other markets to inform trades
I very frequently use prices of other markets to help me determine trades. Sometimes this involves determining a price for a thinly traded market by taking averages of similar big markets. Other times it involves directly arbitraging markets against each other. Strategies of this type clearly fight back against the out-of-date-info and no-quantitative-info problems.
I could imagine both a "soft" form which identifies markets which are similar-but-not-the-same and analyzes correlations to keep the price vector close to its principal components, and a "hard" version which locates and rigorously vets identical markets or markets where an outcome on one implies an outcome on the other and arbitrages these directly.
<!--
Consider the following strategy for a bot.
1. Identify the top markets on the platform by volume/liquidity.
2. For each pair of markets, ask the LLM if they are correlated or anticorrelated.
3. Take some of the pairs that score highly on the volume/liquidity/LLM-assessed correlation.
4. Make a private 2x2 combinatorial market on the two markets.
5. Initialize the prices of the 2x2 market so that the marginal prices of the two markets as the main markets predict, and so the events are almost, but not totally, correlated. There should be a slight correlation in the direction the LLM suggests.
6. As time goes on, arbitrage the markets against each other.
My thesis for why this kind of bot should be profitable is as follows:
- If the 2x2 market is unlisted the bot should be the only one trading on it.
- If the 2x2 market were initialized to be totally correlated, it would be a nothingburger -->
### Identify markets that experience time decay
Many prediction markets can be expressed with titles of the form "Will X happen by Y date?". It does not seem too hard to get an LLM/regex to consistently identify markets of this form. We can then look at the price: If a market like this is unresolved and not at an extremely high price, it is usually a safe bet that "X" has not happened yet. The prices of such markets should then decay over time, but one often finds (at least on Manifold) markets that haven't been traded in a while. This suggests that a bot could trade on the information of the previous price.
A typical way to model this might be to assume that "X" events happen according to a Poisson process. We can then infer the rate of this process from the time and price of the last trade, and extrapolate what the price should be now. Of course, there is the risk that the event is more likely to happen on certain dates than others - perhaps this could also be dealt with by asking the LLM a question like, "which of these dates is the most likely for X to happen?" and using that to inform the model.
### Calibration Bots
In an [earlier post](https://thequantummilkman.substack.com/i/167659639/going-meta-why-predict-rather-than-aggregate) I advocated avoiding calibration analysis in favor of analysis of particular trading strategies. Perhaps the synthesis of this is: We should have more calibration bots - bots which specifically analyze calibration and make bets to correct miscalibration. There are a few possible flavors:
- Sitewide calibration
- Topic-by-topic calibration
- User-by-user calibration (i.e. identify fish)
- The Manifold house bot once did this, which is in retrospect somewhat ironic, since this seems like one of the worst ways to make a profit in terms of keeping new users interested. But this is less of a problem in a bot-centric platform.

## Market Resolution Bot Ideas
Much is already covered in the [post](https://forum.effectivealtruism.org/posts/pLkFmWP3xmGG8YvjP/ai-for-resolving-forecasting-questions-an-early-exploration) I mentioned above. I'll try to keep to ideas not discussed there.
### Combinatorial Markets
I have already written about these [here](https://thequantummilkman.substack.com/i/163818132/a-bot-to-automatically-manage-combinatorial-markets) and [here](https://thequantummilkman.substack.com/i/157285480/logical-composition-of-pre-existing-markets). But it's imporant to realise that this is a type of market resolution strategy that is totally automatic, yet relatively rare on most platforms today.
### Combinatorial choice of LLMs and Resolution Sources
To extend this idea: In designing an LLM/RAG based resolution bot, one might consider questions of which LLM or data source is best, or if there are effective ways of aggregating multiple choices into a single resolver. But another approach is to simply create multiple different markets, each with a different combination of LLM or data source choice. From here, we can already implement simple aggregation schemes like majority vote using combinatorial market over the individual resolutions. Ideally, traders would have the chance to learn more about the nuances of the different systems, and the "best" resolvers (in terms of the usefulness of their resolution decisions in predicting further outcomes) would win market share.
### Lazy resolution
Already on Manifold there are [many](https://manifold.markets/IsaacKing/is-the-wolf-and-sheep-chess-variant) [examples](https://manifold.markets/BoltonBailey/how-many-prime-factors-does-the-180) of [questions](https://manifold.markets/BoltonBailey/how-many-multiplications-are-requir) which are "decidable" in the computational sense. And one could imagine much more technologically useful questions than these (for example, about whether certain training regimes for ML models will produce certain levels of performance).
The downside of such markets is their uncertain resolution date. But as time goes on and compute becomes cheaper, markets like these will only become easier to resolve. One could imagine that joint markets over the time of resolution and the answer could be insightful. One can even think of integrating formal proof into the resolution procedure to allow for the avoidance of "brute force", but that's best left to a future post. Active 14 days ago

"Crane Shit" Weekly Mana Drop Idea
Proposal: Every Wednesday at noon PST, the Manifold Crane flies around a bit on the screen. Then it picks a random market and shits on it in a vile animation, awarding each trader WHO IS ACTIVELY ON MANIFOLD and has traded on 5 markets that day 500x their position on that market.
Why this is a good idea:
Adds a fun game element to Manifold,
Makes a couple people per week really happy,
If the animation is really funny, a screenshot could go viral and bring a bunch of users to Manifold.,
Inspires markets "Will the Manifold Crane shit on me before 2030?",
Most importantly, it gets users actively using Manifold! The rules state the eligible users are online at the time of the shitting and have traded on 5 markets that day, making Manifold more active and fun.

answering questions in DMs before posting to the market thread?
let's say you are running a market about some outcome in your personal life.
A domain expert might consider asking a question that would provide relevant information and help them make a more informed trade.
But the domain expert doesn't know if they will be the first to trade after reading OP's response. Someone else could use the information to snatch the extra mana that was put on the table when the information was revealed.
The domain expert would have a much greater incentive to put effort into asking those kinds of questions if they were guaranteed to receive the response in DMs before anyone else.
example
Alan makes a market about whether his flight will be late. Bob is a plane nerd and knows that planes of type XYZ model ABC23 are much less likely to be late, so he asks what aircraft type he will be taking. Alan reveals that it's type XYZ model ABC23, but Bob is offline. Charlie sees Alan's response and buys NO, eliminating any profit to be had from knowing the aircraft type.
Daniela is going to trade in Esther's market and thinks about the scenario above.
She considers that questions aren't free actions. It takes time and energy to think up clever questions and then formulate them nicely for Esther, who is not a domain expert. So Daniela decides it's not worth the time and effort to think of clever questions only to have Charlie snatch the reward anyway, so Daniela decides to look for easier trades.
This is bad for Esther, because she wants to receive questions she hadn't considered that would improve the market's accuracy. And it's bad for Daniela because she would like to get easy mana from asking clever questions.
solution
simple
OP can incentivise questions by announcing that they will answer questions in DMs first and only post them to the market thread after some time has passed.
the question asker can DM the question to OP and explain they would like OP to not post the answer in the thread until some time has passed.
in practice
But I dunno how much this whole dynamic is a problem in practice. Markets where OP has non-obvious private information also tend to have fewer traders. So, often the question-asker does get to be the first to trade after all.
And manifolders aren't always asking questions purely to profit in the market with the new information. Sometimes they just want to help OP get a better probability estimate, or they want to see how the market's price might shift with new information.
Setting up an informal systems like I proposed in solutions carries its own costs. Many people will misunderstand the purpose of this system. Explaining it takes up time and increases market description length. Explaining this dynamic every time is tiring.
conclusion
I don't have one. This is just something that was interesting to think about. Any thoughts?

Planning something big, but need a small loan to make it happen.
Hi Manifold Community,
I'm planning on a making a large set of questions for a fun real-world AI Safety Futarchy experiment, but I do not have quite enough mana on hand to provide the sort of liquidity it needs.
Perhaps people may be able to help out by offering me a loan? I have a number of investments that should resolve within the next week or two, but I want to pull the trigger on this within a day or so. I need at most 8k total (possibly less), so a loan of 6k would be enough. I'm can commit to pay it back within a month or two at a rate of 2% interest per month. I am trustworthy and have honoured loans before (@100Anonymous can confirm and I currently have a RISK score of 762, https://risk.markets/?q=Jasonb).
If you're not able to provide a loan or assistance but are interested in what I'm planning, make sure to follow my account ;)

An Ads Experiment
I was interested in testing the Manifold ads feature to see what interest it could earn for a market. Moreover, I was interested in discovering more about the two markets I had posted. They were both topics that Nate Silver at FiveThirtyEight considered important questions, and they both have large potential impacts on the United States. However, they are both relatively long term markets (one not resolving until the 2024 election, one not resolving until 2030) and had not received very much interaction.
The two markets are:
(https://manifold.markets/embed/Gabrielle/will-any-us-supreme-court-justice-r)(https://manifold.markets/embed/Gabrielle/will-the-democrats-control-the-us-s)Both markets had been quite inactive, with the Senate market not having activity in the previous ten days and the Supreme Court market only having one non-bot trader in the previous twenty five days.
Before placing the ads, I added M$300 of subsidies to each and let the subsidies fully settle, to hopefully help add incentive to bet in the market. The Supreme Court market had 11 traders before adding subsidies, and gained 3 more traders after I added the subsidies but before I placed the ads. The Senate market had 13 traders before adding subsidies and gained no more between that and placing the ads.
I did not post the markets in any context other than the ads, so hopefully the activity was entirely from the ads and the subsidies.
On 2023-04-02, I placed ads for M$500 on each market. For this to be directly profitable for me, not even including the subsidies, both markets needed to get 50 additional traders. For it to be worth it from a knowledge perspective, I wanted to see at least 10 additional traders.
The ads were simply an embed of the market, without any additional text advertising the markets or stating why they were important or potentially profitable. While those would likely be good, I wanted to test how people interacted with very basic ads. For context, you can see the (now used up) ads at https://manifold.markets/post/ad-025e55df1bab and https://manifold.markets/post/ad-a64a5b9a4ee3.
I then waited until the ads had been completely viewed. I precomitted to publishing the results, regardless of the outcomes.
As of 2023-04-11, all of the ad views had been watched. For the Supreme Court market, that was 100 watches and 75 skips. For the Senate market, that was 100 watches and 76 skips.
The Supreme Court market had 26 total traders and the Senate market had 18 total traders, meaning 12 new traders and 5 new traders respectively compared to before I placed the ads. From my perspective, it was barely worthwhile for the Supreme Court market, getting slightly more than 10 additional traders, and it was not worthwhile for the Senate market.
Based on this, I would not use the ad system again in this way. Most importantly, I think that I need to add some call to action, saying either that it was particularly profitable (extra subsidies) or particularly important. It also seems like the ad system just doesn't encourage people to interact. Only five out of a hundred watches on the Senate market actually interacted, which is an abysmally low rate. An M$100 bounty would have been equally as efficient as the ads, and it would feel like a much fairer system. All of the users that watched and didn't interact or skipped wouldn't have had their time wasted, the users that watched and interacted would have gotten a much better reward, and it would have cost me the same.Active 23 days ago

Now we actually track per-answer volume, which the trending sorts by now, (I haven't actually backfilled this, though). This should better highlight the answers people disagree on.
It was previously sorting by the subsidy pool, which used to track the unique traders on that answer, but we had deprecated this months ago.

What's the incentive to create markets?
Right now, it seems to me that creating a market is always a net loss. The user base isn't large enough to have enough traders on a question to be able to break even on the bounty awarded for each unique trader on a 100 mana question, let alone anything higher. Mana is relatively scarce unless you are consistently seeing big wins or buying mana with real world money.
I don't have a wish to profit off questions, but I'd like to not take (relative to my "net worth") gigantic losses whenever I post a question. Whenever I have enough mana to post a question, the cost/benefit of doing so always results in me instead placing bets as there is a chance I can make myana back or more whereas posting a question seems to always without question result in a loss unless I post a question I know will resolve a certain way and bet in my own market.
This seems to result in most questions being posted by the same small group of people who have the mana banked where 100 or 1000 Mana is a small enough percentage of their total net worth where it doesn't "hurt" to lose that amount. It ends up with primarily whales being the individuals who direct the topics that appear on manifold and makes it so markets seem to only exist for topics that revolve around those individuals interests causing an issue of low diversity on market topics.

Superforecasters aren't real
(You can also read this post on Substack if you prefer substack cookies....)
Broadly speaking, there are two ways to be wrong about the future.
The first is assigning the wrong probability to an event. To be right about the future you need to assign the correct probability. Manifold, Polymarket, Metaculus and others reward this and are very good at it. If Polymarket says Donald Trump has a 60% chance of becoming president, he probably has a 60% chance of becoming president.
This extends to conditional markets and more complicated constructions as well ("If Trump wins, what will the tax rate for the top 10% be?"). We can call this ability "Question Answering". You have a question; Manifold answers it.
But what if you wanted to know the geopolitical risks of owning TSMC? You can't arbitrarily divide the question into three sub-questions. You have to ask what options China has at its disposal.
Say you had an oracle that said, "The odds of a Chinese invasion of Taiwan by 2028 are 14%," that still wouldn't give you enough information. What about a full-scale blockade? The oracle answers 8%. Could China just blockade materials important to TSMC? What about assassinating TSMC scientists? Can China get an anti-US politician elected?
No amount of time with the oracle will tell you how much geopolitical risk is priced into TSMC's price. The second way to be wrong is to ask the wrong questions. To be right you need to be able to categorize the possible outcomes, judge their importance to the question and determine which outcomes are mutually exclusive. We can call this "Question Framing".
So far, I've assumed that Question Framing is followed by Question Answering; after the forecaster generates and categorizes the scenarios, he gives you the odds. But notice it doesn't have to be that way. We can have one person who's good at thinking through scenarios and another who's good at judging the likeliness of each scenario.
Therefore, a reasonable approach would be to find a good Question Framer and use their framing to make a market "which of these will come to pass".
A "superforecaster" is an expert Question Answerer. According to Wikipedia they're good at "inductive reasoning, pattern detection, cognitive flexibility, and open-mindedness" which boil down to eliminating biases, disregarding noise and statistical thinking. Notice, there's no reason to assume that he is a good Framer. Question Framing takes domain expertise and creativity. Incidentally, I don't think biases hurt Question Framing.
Because Framing and Answering draw on different skill sets, a superforecaster adds little once prediction markets exist. What we need are good Question Framers and the market will take care of the rest.Active 2 days ago
Futarchy would be better with combinatorial markets
A number of (old and) recent blog posts and manifold markets have come out debating the efficacy of Futarchy.
This post will address none of these! Instead, I'll cover some thoughts (originating mostly in Manifold discord discussions dating a few years back) about what I think is likely a strict improvement to futarchy as it is almost always presented. Namely: Rather than using prediction markets that replace the "called-off"/"reverted"/"N/A" bets with a combinatorial market over the decision and outcomes.
Futarchy as it is usually explained
Here is an explanation of futarchy (really it's an explanation of "decision markets", which I think is the right term for the decision making mechanism behind futarchy).
We have a decision to make, let us suppose there are two choices and each choice can either lead to a good or bad outcome (you could imagine more choices and a larger spectrum of outcomes, but this is simpler to explain. All the ideas in this post can be generalized to other settings). We want to maximize the chances of getting a good outcome.
We make two prediction markets
The first market will:
Resolve YES if option A is chosen and we get a good outcome.
Resolve NO if option A is chosen and we get a bad outcome.
Resolve N/A if option A is not chosen, meaning all trades made in the market will be undone, as if they had never happened.
The second market will:
Resolve YES if option B is chosen and we get a good outcome.
Resolve NO if option B is chosen and we get a bad outcome.
Resolve N/A if option B is not chosen.
Thus the first market price reflects the probability of getting a good outcome if A is chosen and the second market reflects the probability of getting a good outcome if B is chosen. We therefore choose according to which market has a higher price/probability (either averaged over some window, or at a specific time)
The issue with N/A resolutions
The issue with this design is the part where we undo all trades in the market for the option that isn't chosen.
To see why this is a problem, or at least more complicated than it appears, consider the following scenario:
You think option A is underpriced, so you put €50 on the platform to buy 100 shares of YES at 50%.
The rest of the market comes around to your point of view. The probability of a good outcome for option A goes up to 75%. Yay!
You sell your 100 shares for €75.
You withdraw the money from your account, and buy yourself something nice with the €25 you profited.
Option B turns out to be priced even higher, so option A resolves N/A.
At this point, the market has a problem. It's supposed to undo all the trades made on market A, which should mean making sure that the profit you made is reverted. But you have already left the building! Now the prediction market has to find someone to go out and break your kneecaps to get you to return the money.
More seriously, the upshot of all this is that the platform can't let you cash out your profits, or use them to bet on other markets, until the decision is made. This restricts the usefulness of your holdings and makes you less likely to trade on the markets in the first place.
The better option
But this is unnecessary. Here's an alternative market design for futarchy based on a single market with four linked share types.
The first share type pays out if decision A is taken and we get a good outcome
The second share type pays out if decision A is taken and we get a bad outcome
The third share type pays out if decision B is taken and we get a good outcome
The fourth share type pays out if decision B is taken and we get a bad outcome
But now that we don't revert the markets, how will we know what the conditional probabilities are?
Using the law of conditional probability!
$$ P(Good | A) = P(Good & A)/P(A) $$
Really this is just how conditional probability is defined in the first place: The probability that we get a good outcome given that we choose A is just the probability of choosing A and getting a good outcome, divided by the chance that we choose A at all. The probability that we choose A and get a good outcome is the probability given by the first share, and the probability that we choose A at all is the sum of the probabilities of the first two shares. Therefore, we can caluclate the conditional probability and use it just as we would in normal futarchy.
But what if I want to make a trade that pays out like the conditional markets do?
You can still do that!
Let's say that that we're in the situation from step 1 above: The conditional probability of a good outcome given A is 50% according to the market, and you want to spend €50 making it higher, but you want to do this in such a way that if option B is chosen, you don't have any profit or loss. The first thing to do is to buy 50 shares each of share types 3 and 4. This costs less than €50, since the probabilities of outcomes 3 and 4 can't total 100% or more, and it guarantees you'll be left with what you started with if option B is chosen. Then, you simply spend what remains of your €50 on shares of the first type.
Because all of this is done on a computer, the computer can even simulate for you what the outcome will be, so that you can get exactly the same user experience as if the market were conditional.
What advantage does this have that we don't get by conditional markets with locked-in profits?
Let's continue the thought experiment above.
After your initial buy of "Good conditional on A" You have 50 shares each of (B, Good) and (B, Bad), and 100 Shares of (A, Good).
Again, the rest of the market comes around to your point of view. The probability of a good outcome for option A goes up to 75%.
You again sell shares as if you were using conditional markets.
In the scenario above, you sold 100 YES shares in A at 75%, which is equivalent to buying 100 NO shares at €0.25 per share.
So the analogous thing to do is to spend €25 to buy 25 more shares each of (B, Good) and (B, Bad), and also 100 shares of (A, Bad)
Thus you now have 75 shares each of (B, Good) and (B, Bad), and 100 shares each of (A, Good) and (A, Bad)
As is usual in prediction markets, you can redeem a complete set of shares for €1. So you do this x75, and so you get back all of the €75 you put into the market, and you still have 25 shares each of (A, Good) and (A, Bad)
So there's a few benefits over the locked-in profits approach: The first is that you are able to cash in at least some of your shares (though technically the locked-in profits model could be implemented smartly enough to let you withdraw the minimum of all amount you would be able to withdraw under all future scenarios).
But more tellingly, the benefit is that your long position in A shares is now tradeable. If you think the probability of A being chosen is overpriced, you can sell that position without further need to add money to the system. Or if you don't have a strong opinion about what decision will be made, but you trust that the market is efficient, you can sell your position at market price to reduce your risk.
What are other ways to frame the benefit of this approach?
Another way you could think about this is that it allows more general flexibility in how you express your needs to the market.
For example, it's not often talked about, but one source of liquidity for futarchic markets could be individuals who have a more direct stake in the decision and its outcome than the typical trader. Indeed, many government policies are important to groups that they affect directly. you could imagine that there's a trader who would be especially distraught to see the market choose option B and simultaneously get a bad outcome (perhaps they are part of the group it is speculated policy B would most hurt, if it goes wrong (we could even make separate arbitraged markets on the parts of welfare sustained by different groups to better capture this)). That trader could hedge their risk by buying shares in the possibility that this would come to pass. But why should we force them to implicitly take a long position in outcomes in A in order to be able to?
Open question: Details on how liquidity changes
My examples above tries to be as clean as possible in showing the analogies between the two different market structures. The main difference with the combinatorial market is that it allows trades directly on the likehood of decisions.
Could this be a bad thing in some cases? If one option is obviously much better than the other, perhaps it is also obviously more likely to be chosen, which could lead to less available liquidity in the market shares for the alternative. I think this is hopefully not too much of an issue if the liquidity provision is designed carefully - in the worst case we could partially simulate the liquidity structure of the conditional markets by setting up separate automated market making mechanisms trading the conditionals and then arbitraging them against the main markets. It's worth noting that even if the prediction platofrm itself doesn't allow trades on decisions, a black market could spring up to take this liquidity anyway.
Maybe it's actually actively bad to spread information about how low the likelihood of one outcome is, precisely because it will cause people to see that correcting prices on that conditional will not be profitable. But yet again, maybe it's better to have this happen than to have only traders who are not sophisticated enough to estimate this chance accurately for themselves be the dominant forces in that market.
In any case, I would like to see more experimentation with futarchy structured this way.

Market of the Week
One of the problems for medium-mana and high-mana users is that almost all markets either have low trading volume, or take months/years to resolve. If you want to make a profit, there is little option other than dumping all your mana into these long-term markets, and then coming back to the site months later to reinvest. (Or, more likely, forgetting about the site altogether.) My idea is to have a "Market of the Week" tab which contains a market which resolves at the end of the week. It would be chosen by the mods, based on what they think would be most engaging and informative given current events.

Mana should go out of the system to avoid inflation
Currently, there is no way to remove mana from circulation. This can cause manaflation, which would significantly reduce the value of mana. I propose two ways of removing mana:
1. Restart the charity program, at a much lower rate (2500:1, for example)
2. Do not return net loss into liquidity. For example, say someone bets 20 mana without any human counterparty. Today, the counterparty is the AMM, which will give the market creator 80 mana (assuming market subsidy is 100 mana) if the person is right, and 120 mana if wrong. Instead, the AMM should simply give the market creator 100 mana if wrong. This would make the 20 mana disappear, removing it from circulation.
If anybody wants to create a market about this, I'll pay you 50 mana. Only paid to first 2 markets.Active 4 months ago

Praetors shall certify elections to ensure they are sufficiently democratic, have reached adequate quorums, have allowed proper time for deliberations, and have not been manipulated.
The government should endeavor to fund itself. To manage the financing and operations of the government, administrators known as Quaestors shall be appointed by the Senate. Quaestors shall manage the assets of the government and keep account of its finances.

Make league profit scoring fills-aware
Intro
"League Profit" is the profit calculated specifically for the "League Season". It is not the same as overall account profit. At the time of writing, league profit considers:
the current value (at any given moment)
of all bets (a 'bet' is roughly equivalent to a single time clicking the 'Buy' button, this also includes 'sells' and 'limit orders')
placed after the start of the current season (and before the end of it)
except NOT counting bets made within the first hour of a market created by the bettor
Improvement
I argue that the league profit should also carefully examine "fills", which are a mechanism that tracks what counterparties your "bet" was made against. In many cases, the bet is filled directly against the AMM. In markets where limit orders are present, the bet may fill against those limit orders in addition to the AMM.
If your bet "fills" against your own limit order, that portion of the bet should not count for league purposes.
Any time you trade into your own limit order, it is essentially a "nothing". Your Yes limit order for 50 shares is matched by your No order for 50 shares and you gain/lose no mana. But for the purposes of league scoring, trading into your own limit order can create fake league profit -- here's how:
Base case: If both the limit order and the filling bet were made in the same season in someone else's market, then it counts nothing toward your league profit.
If your limit order was made on your own market within the first hour of its creation, and then you fill it after 1 hour, only the fill counts toward your league profit. So you could easily (intentionally or accidentally) end up with a weird situation where you had a no-overall-profit trade that causes a large up/down swing in your league profit.
If your limit order was made in a past season on any market, the same thing applies. When you (accidentally or intentionally) trade into it, you have a no-op overall but it counts the 2nd leg for league purposes.
In the two cases where you filled your own limit order where only one side counted, using it in any way for league purposes kinda sucks:
If you were buying into it accidentally, for example when news broke on a market, you're rewarding yourself with excess league profit by trading against yourself. It could even be a large amount depending on the size of your limit order. You can also accidentally end up with huge losses, which also sucks.
If someone was doing this intentionally (they can very easiliy make it look accidental), then they could be picking up small amounts of one-sided 'league profit' all over the place. There's no reason to make it so easy to do this. Yes, doing it intentionally would already be against the rules, but "at least shut the door" is a good principle.Active 4 months ago

Do you think you could help another user create a valuable market?
Imagine for the sake of this question that Manifold had a program that would compensate you (mana, maybe even real money) if you would be able to help another user come up with a market that was very valuable to them.
I'll do an entire example just because:
Let's say a new user Alice really wants to know what (specific!!!) date(s?) to plant her large yearly spinach crop. She just signed up to the site, she's never made a question, and she hopes that the markets can help her make a decision.
If she plants too early, they won't grow due to the cold weather. If she plants too late, they'll get cooked by the sun before they're ready to harvest. It's a slim window and she hopes to maximize her yield.
Instead of relying on general published information about the growing season, Alice hopes Manifold can make specific predictions about her specific situation, in markets tailored to her!
---
1. Do you think you could help Alice create 1 or more questions that would help her decide when to plant?
2. Are the questions you think of very straightforward or more creative interpretations of her situation?
3. Do you have some way of demonstrating that your questions helped Alice make a decision that was better than not having any markets?
4. Do you think the amount Manifold might compensate you for helping Alice would impact the quality of your work?
Feel free to respond as broadly as you wish, it's just a starting point.

Bounty: Recommend me a secure, convenient way to manage my passwords/other auth data
In light of the recent, massive 16B password leak, I think it's finally time to tackle this issue. I hate password management. I am asking for your help:
I want a convenient, centralized way of managing my dozens of logins to different websites, accounts, devices etc etc. Will give out a bounty of up to 5k mana for an ideal solution to this issue, and lesser bounties for any other recommendations that make my life easier.
EDIT: Yeah forgot to add: Open Source is a requirement, for reasons that should be obvious.Active 4 months ago

My "Net Worth" should include my stake in AMM pools.
If I have invested 1000 mana into an AMM, my net worth should not immediately decrease by 1000 mana. The value of my investment in the pool should be reflected in my account status.
Discuss.
