Loan changes

A few changes have been made to daily loans: The loan rate has been raised to 2% per day. The max cumulative loan you can receive on any single market has been lowered to 2% of your net worth. ̶Y̶o̶u̶ ̶m̶u̶s̶t̶ ̶h̶a̶v̶e̶ ̶a̶ ̶b̶a̶l̶a̶n̶c̶e̶ ̶o̶f̶ ̶l̶e̶s̶s̶ ̶t̶h̶a̶n̶ ̶1̶,̶0̶0̶0̶ ̶m̶a̶n̶a̶ ̶t̶o̶ ̶c̶l̶a̶i̶m̶ ̶a̶ ̶l̶o̶a̶n̶.̶ The terms of previous loans are unaffected by these changes. We are still very far from the final iteration of loans. Further changes are likely. Suggestions welcome.

Manifold should lean into the loans system and improve it.

The Manifold loans system is fantastic, for several reasons. It provides daily liquidity to users, which is good for retention. It helps with capital efficiency on long-running forecasts. When used responsibly, it allows low-risk leverage across diversified markets. It's a feature that makes Manifold much better than other sites in many ways, and Manifold should lean into it. My improvement suggestions: Bump the loan rate up a little. Get a little stricter with the per-market size limits, and especially restrict "lots in each of a couple" even harder than the same max position size but only one large position. Allow loans against full value of the position including unrealized gains Allow loans against provided liquidity remaining in markets Claw back underwater loans at the same rate that new loans get handed out. (Or slower, I guess, if you're feeling generous. Or rebalance in some fancier way to ensure that "click the loan button" always has a positive payout.) Optional neat feature you could tack on: when positions include a cash equivalent element (NO in multiple MC outcomes, or YES in all of them), immediately loan out the cash equivalent. Don't include this portion in the market risk limit. This would make limit orders in multiple choice markets, especially NO limits, far more powerful and user friendly. Other neat feature, if you're trying to treat Mana more like $ in a serious way, and promote long term, high certainty, or small-marging bets: pay interest on positions held (similar to Kalshi), but for many reasons pay it in the asset held. This includes cash holdings, shares, and also shares held by AMMs (interest paid to the AMM). This is probably out of scope for the first pass but it would be super neat.

Problems with Manifold's loan system (it should be interest payments instead):

Hey all, I wrote a post on Substack where I argue that Manifold's loans do not solve discounting-induced miscalibration, and that interest payments are a better system: https://zeroexpectation.substack.com/p/problems-with-manifolds-loan-system Summary: Considerations of opportunity cost reduce the value of betting on long-term markets, or those near 0% or 100%, making markets miscalibrated. The loan system reduces some of the opportunity cost of trading, but not all, because the initial cost of the bet always exceeds the loaned amount, and the cost comes earlier. Interest payments solve this by compensating for time value, not just reducing the cost. With interest payments, it is possible for a fair bet to remain fair even if you discount future profits, and this is not possible with loans. The system is also simple, easy to understand, and matches what other prediction markets like Kalshi and Polymarket do.

Let's build the worlds tallest building.

Who's with me? Post your technical proposals here, then we move on step 2, funding, consulting, and planning. Plan 1: Digory – Space elevator based, see Issac Author (or Greg Egan). plan 2: Fergus – Wide base, go wide or go home. plan 3: Alan (me): Skeletal block – Take a metallic skeleton of a cube, let's say 10m by 10m by 10m, this forms a modular part of a larger building, these skeleton blocks are all the same size and fit together along their edges, like Minecraft blocks do. Habitation block – A hollow cube slightly smaller than a skeletal block, fits inside a skeletal block and can be locked in place or unlocked and slid along to lock into an adjacent skeletal block instead. Habitation blocks are lined on the inside with dry-wall, windows and furnishings, or with ventilation infrastructure and machinery, or with storage space, or whatever is needed in that part of the building. Divider – A sheet of solid material the width and height of a skeletal block, it can be installed on an edge of a skeletal block to isolate it from its neighbours. A divider between two skeletal blocks (so not on the edge of the building) borders both blocks, if installed then fluids and light cannot travel from one block to another across this edge. Unattractive blocks – As the building grows space in the middle of the building becomes unattractive, therefore new skeletal blocks are added on the outside of the building, habitation blocks are slid around to get them all adjacent to or near the outside starting with the outermost ones, and the skeletal blocks in unattractive locations are retired. Retiring skeletal blocks – To retire a skeletal block, install dividers on all sides needed (up to 6) to isolate it from all non-retired blocks, then fill it with concrete, make sure that the relevant concrete transport related habitation blocks neighbour it first. The building is shaped like a stepped 4 sided pyramid, two tall to every 1 wide for extra height. Before voting for a resolution, we need both more plans, and more details on the existing plans.

Margin loans are good, and complement interest payments

This is a followup to my previous post, and partially a reply to Brad's substack post. Manifold's margin loans help with time discounting of long-term bets, but that is not the only thing they do. As Brad writes, they do a far from perfect job of it. Interest rates are mostly better at serving this goal. Interest rates alone don't solve the problem, and margin loans also provide several unrelated benefits in a highly cost effective way. The core reason interest rates don't fully solve the problem is that good bettors have an opportunity cost (they expect to make money betting), and the interest rate doesn't change that. Rational bettors generally should prefer a secure return over one with risk, and so should only bet when they think they have an edge -- and it matters how long that edge takes to realize. Interest rates really only address the opportunity cost of not investing in risk-free investments (bonds). The Manifold margin loans help somewhat on top of interest rates, because they ensure the capital is only locked for a fixed portion of time (effectively 1/(margin loan speed)), regardless of the length of the prediction, in the long-running case. The interest payment system is doing the heavy lifting, but they complement each other. Margin loans also provide an increase in the velocity of money on the platform. People bet more. It is not a priori obvious what the desired ratio is here, and I see no reason to suspect it should naturally be what you get with no margin loans. Manifold should benefit from increased activity and increased trading. Traders with a diversified portfolio should naturally be willing to take on risk at a level that corresponds to some margin usage (assuming it's cheap enough). Low-multiplier margin loans, with some element of restriction for risk management (especially on large accounts), should be a win-win. Margin loans also provide a daily incentive, which is especially important to free to play or otherwise small accounts (anyone where the daily / weekly bonuses are relevant). Log on, click button, get liquidity. The risk of the loan to both trader and Manifold is low. And it provides a daily dose of liquidity to drive engagement, that costs less for Manifold than creating mana from the mana faucet. The cost to Manifold is simply the risk that the account is not diversified and ends up negative; risk management (such as the existing per-market cap approach) helps here. For this use case, the Manifold approach (daily loan as a small portion of position) is better than a traditional approach (as needed with risk management limits). The daily loan system also naturally acts as a risk management system: a trader can't see a single large bet they want to make and use all their margin on it at once, they have to wait for that margin to become available over time. For large accounts, the trader wanting margin would probably prefer a traditional approach of as-needed margin loans rather than daily, and be willing to pay interest on it. How to do risk management well is a whole separate topic (and post), but some things worth considering: How long does it take to reach 2x or 3x leverage? How many markets worth making large bets in does a trader need to find to reach 2x or 3x leverage? (For a simple per-market cap, it's leverage / (per market cap), so 2x leverage and a 5% cap means spreading out across 40 markets. Hopefully that's highly diversified! Some closing thoughts on things that might work well in this framing: Daily loans have a leverage cap or an absolute cap, which can be removed or raised by agreeing to pay interest on the portion in actual use. "Balance" would then be "total avialable liquidity" and interest would be owed on (total investment - total account value - free loan cap). The cap should not be at zero, because you want to encourage free to play accounts to use the system and not be scared of it. Raising caps or otherwise loosening risk management might be a good thing to tie in with real-money spending, such as a subscription or a bonus on large purchases. Overall, interest payments on positions should be viewed as complimentary to margin loans, not substitutes. And daily loans vs as-needed traditional margin loans should be viewed as a mix of engagement optimization and risk management.

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.

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!

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.

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? Who thinks this would be a bad idea?

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.

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. I know we do see the liquidity in the info screen, but nevertheless...

Why did India remain pagan?

Paganism has been stamped out in the vast majority of the world either to the Abrahamic religions or Buddhism, but India, the world's most populous country, remains pagan, not falling either to Christianity or Islam. India's successfully fending off a Buddhist challenge can be attribute to low fertility among Buddhists. A writing direction theory can explain religion in China and Japan, but not (as far as I can tell) in India. Hard mode: why did Hinduism not become proselytizing in any important way?

Manifold shark tank!

This is a creative version of shark tank but for manifold markets. It would work by someone pitching a market idea in the comments, and based upon the market idea, and how much people enjoy it, people in the comments can reply, and maybe invest in it. 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.

Bring back the "Subsidized" toggle

We used to have a market state called "Subsidized" and "Unsubsidized", where markets that aligned with certain criteria earned special rewards from Manifold, while other markets did not. At one point, the subsidized markets earned mana that was injected into the market's liquidity pool, and also generated "unique trader bonuses". The Subsidized state went away last year during some other changes, but now is a good time to bring it back. I think varying the trader bonuses awarded to markets depending on their topics and the creator's management skill is good for the site. I am not convinced we 'need' to bring back the per-trader liquidity subsidy. I think it mostly only makes sense in the very most interesting markets. Also I believe this toggle aligns well with whether a market "should" appear in major advertising locations such as the homepage feed. I sometimes see markets appear in the feed specifically because they are bad markets and generate a lot of controversy. Instead of pumping them up, up, up, we might benefit from de-prioritizing them. Here are a few things I think we could do to a good result: Default is something similar to what we have Double subsidy would give a good market extra rewards and boosting! Markets with the extra subsidy toggle would be a good candidate for liquidity injection. Reduced subsidy would de-prioritize a market and give it lower trader bonuses, but still allow you to create markets you think are fun and will generate good activity on the site

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, Ryan (NG on Manifold)

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. JOHN HANCOCK

Manifold should do anything other than throwing away excess shares when liquidity is added to Multiple Choice or Set markets

Caveat: You can prove that this breaks something or leads to 'cheating' and we can throw the entire idea away. It might not be perfect, but I argue it is better than the status quo. Background Manifold still uses the maniswap AMM for binary markets, which has a very handy solution to the "excess shares" issue when liquidity is added to an existing pool. Maniswap adjusts the p parameter to allow better use of subsidy mana without throwing away shares. This causes some changes in behavior of the AMM when betting against it, but usually it ends up better than just throwing away a lot of mana. When Multiple Choice markets were introduced in 2023, one concession made in the implementation was fixing p = 0.5 due to Math Reasons. It mostly didn't matter a ton at the time, some reasons being: Manifold was pumping liquidity into markets for every trader, so it was papered over; the actual amounts of mana used were significantly smaller, 100 mana was about what 1000 is today due to mana inflation over time. Later on, Set markets were introduced as "We took the Multiple Choice markets and just turned off the auto-balancing". These also have a fixed p = 0.5. Problem So, what's wrong? On both Multiple Choice and Set markets, significant amounts of liquidity added after market creation are totally lost. Your mana basically just goes "poof". In the case of Set markets, it's really simple. Since p = 0.5 is fixed, if you subsidize a Set market where answers are far from 50%, a significant portion of the amount you subsidize is thrown away as excess shares. You don't get them back. Manifold doesn't get them. They're just vaporized. In the case of Multiple Choice markets, it's a little more complicated, but in most cases you will be vaporizing somewhere between.....5% and "a massive amount" of your mana. Concrete Example Here's a concrete example to help you understand the issue. A market is created with 3 answers A, B, and C, with 1000 mana as the initial subsidy. Traders do some trading and the market ends up with A = 80%, B = 10%, C = 10%, like this: Total Liquidity: 1000 Option A 80.0% Pool Yes shares: 176.8 Pool No shares: 707.1 Option B 10.0% Pool Yes shares: 1060.7 Pool No shares: 117.9 Option C 10.0% Pool Yes shares: 1060.7 Pool No shares: 117.9 Pool Value: 707.11 At this point, some of the initial 1000 mana in the pool has been used up by traders who have moved the market from 33/33/33 to 80/10/10, as represented by the "pool value" of 707 mana. If you found this market and decided you wanted to add more liquidity to it at this point, perhaps you would supply an extra 1000 mana. Pause for a moment and make a guess, what will the pool value be after we apply 1000 mana of subsidy to this market? Here's the market state after the 1000 mana subsidy: Total Liquidity: 2000 Option A 80.0% Pool Yes shares: 294.6 Pool No shares: 1178.3 Option B 10.0% Pool Yes shares: 1531.9 Pool No shares: 170.2 Option C 10.0% Pool Yes shares: 1531.9 Pool No shares: 170.2 Pool Value: 1084.07 Ha, did you think that spending 1000 mana would result in more than 377 mana added to the value of the pool? In this example, 778 Yes shares in Option A (present value of 623 mana) were completely vaporized during the subsidy process. You never get it back and no one else does. (You will just have to take my word for it, the math part would take a long time to explain.) Possible Fixes The main thing I care about is doing absolutely anything other than the status quo. I often see multiple choice markets that would benefit from a lot of subsidy, but in many cases it is so inefficient that users would be crazy to do it. The best fix is to keep track of all excess shares, but choosing a method to do so might rub people the wrong way. This is a play money site, we can just try stuff. I'll present 2 options, someone else might have others...they would both work on both Multiple Choice and Set markets: Option A: just give the subsidizing user the excess shares as a "bet" straightforward implementation need to decide on the "cost basis" of this bet because it will affect profit (a safe one is one mana per share which always results in negative profit but not by too much) can be traded like any other shares Option B: keep track of the excess shares using some other method and pay them out on market resolution they could be a special "bet" that cannot be sold/redeemed and don't count as profit or they could be kept as a pool-adjacent value that just remembers how many excess shares any user owns, to pay back at resolution time Concerns Basically you can make slightly one-sided trades at the expense of funding the AMM. Maybe it is abusable but I can't see exactly how it would ruin things, especially since we cannot withdraw liquidity in the MC markets. Like you could effectively exit out of a position by funding the AMM rather than changing the market price. Would love any feedback!! Where have I messed up?

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!

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.

Advice for job search?

The last time I worked was before the pandemic, during which I developed posturally hyperextended and (in 2022) bicameral schizophrenia. I have since been on Social Security disability, due to the extreme effect hyperextended schizophrenia had on me. 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. I will give bounties of up to 150 mana for each piece of good advice. You are free to ask questions, though I may not answer all of them.

Bounty for finding sub-$100 priced new Windows tablet (150 mana).

They existed a decade ago and were called WinBooks. The ROM sucked, but they were perfectly usable for python, emacs, git, etc. Even had a USB 2.0 port, which was extremely useful for file transfers and adding a physical keyboard. If they existed a decade ago, something like them should exist now.

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?

Which specific sexual act pleasantly surprised you the most?

Want to create a market around this and need options. ChatGPT gave me the following 10 options already: Receiving oral while blindfolded (Heightened senses, unexpected rhythms — a deep dive inward.) Giving or receiving rimming (analingus) (Surprisingly intimate, and often far more pleasurable than expected.) Being tied up with silk or rope (Shibari-style light bondage) (Not just kinky — it can feel artistic, meditative, and deeply sensual.) Face-sitting — being sat on or doing the sitting (Power, closeness, control — and maybe a little worship.) Pegging or being pegged (A shift in roles that opens unexpected doors — physically and emotionally.) Cunnilingus with a vibrator involved (Double stimulation can create a cascade of pleasure that surprises both partners.) Mutual masturbation while holding eye contact (So raw, so real — turns vulnerability into a shared high.) Anal fingering with lots of lube and patience (A lesson in trust, relaxation, and slow-building waves.) Morning sex without rushing (Sleepy bodies, slow movements, sunlight on skin — surprisingly profound.) Public play (e.g., whispering fantasies or light touching under a table) (The thrill of being almost seen — danger without real risk.) Sex after an argument (make-up sex) (When emotions melt into intensity — and something raw comes through.) Deep eye-gazing during penetration (Turns sex into a mirror — often more surprising than the act itself.) Use of a strap-on by a female partner on a male partner (Role reversal with power, tenderness, and mutual discovery.) Light spanking with clear consent and build-up (Pain and pleasure intertwined — surprisingly connective.) Tantric stillness — entering and staying still, just breathing together (It sounds like nothing. But it can feel like everything.)

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).

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.

Senatus Usoresque Manifoldenses

We, the users of Manifold, propose organizing into a republic, centered around a single voting body—a Senate—deriving its legitimacy from the support of the users, and bound by the Manifold terms of service and moderators. Senators shall be selected through direct election by Manifold users.  A senator shall be elected to the voting body if they win an election of the Manifold users.  A senator shall serve a 1 year term. Senatorial elections may take many forms.  To ensure the legitimacy of these elections, judges known as Praetors shall be appointed by the Senate.  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. The policies of the government should be guided by futarchical principles.  To manage the implementation details, Futarchors shall be appointed by the Senate. The Senate, as a deliberative body, shall have discretion to determine its own rules.  To initiate these rules, we propose Robert’s Rules of Order. This constitutional convention shall elect and appoint an initial triumvirate of Senators, so that appointments, elections of the Senatorial body, and the administration of the state may commence.

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.

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.

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. This way traders can compete in a market which is both short-term and high-volume.
