Will this market's % equal a prime number at close?

Resolved
NO

This market resolves YES if the percentage at market close on January 2nd, 2025 after 11:59 PM ET rounds to a prime number. Otherwise resolves NO. Number will be rounded using the same rounding algorithm that Manifold uses to display to users.

For example, 19% would resolve YES and 8% would resolve NO.

  • Update 2024-26-12 (PST) (AI summary of creator comment): Rounding Behavior for Low Percentages:

    • 1.5% would round up to 2 and resolve YES

    • 1.4% would round down to 1 and resolve NO.

Well played, everybody! It was really exciting to see so many people get really into the strategy on my market. Thanks so much for the fun!

you have no clue how close i was

opened a Ṁ5 YES at 2% order

@summer_of_bliss nooo hahaha! ah well, well played

@summer_of_bliss had a 50k limit ready, pressed it once clock it 11:59:59, “error”. whoops! gg gamers

@summer_of_bliss Curious, what % was the limit order(s) going to be at?

@SentientTree 41%. initially thought 97% but too risky if someone had a huge no order waiting, they could blast through

@summer_of_bliss If they had a spare second a NO holder could still buy YES to 42%

@SentientTree yeah that’s a risk but i don’t think anyone would have had the reaction time to see 41 was prime then trade in less than a second

@summer_of_bliss I have primes memorized but didn't trust myself to get the last trade in.

If I was a whale I would've guaranteed a NO with limits between consecutive composite numbers. Lower values (8 & 9, 9 & 10, or 14 & 15) would provide better leverage against those piling on with NO at the last minute at the risk of someone being able to blast through. I'd put the NO up with ~8 seconds to go and YES with ~3 to account for lag (assuming I had a large pre-existing NO position that isn't going to flip).

@SentientTree this is a good strat actually. as with all these you’d have to be sure you’re the biggest player in the market tho bc of the risk you mentioned

@Brad Surely you didn't wait until 11:59:59 Eastern -- the market closed at 11:59:00, as I pointed out below!

@Calibrate oh yeah sorry meant 11:58:59

sold Ṁ90 NO

Honestly I'm just letting people jump the probability and then I'm buying it back down just for the profit lol

@Gameknight Nice, I left a bet of M50 on NO and won

If a whale puts up massive limit orders at the last minute, they can guarantee a NO resolution (by putting limits between composite numbers) or guarantee a 50/50 (between a prime and a composite). The only consecutive primes are 2 and 3 but putting a big NO limit at 3% is sure to lose money for the whale (everyone would buy YES and their position would flip to NO).

In other words, I don't see how this market could possibly be worth >50%

@SentientTree Crediting you with producing bystander if this doesn’t happen

Looking to exit my position before the last-minute craziness - take my limit order at 38%! (YES is only worth 25%)

@SentientTree Kinda wish I hadn't offered that now. 1.3k profit regardless

Closes at 8:59:00 PM Pacific / 11:59:00 PM Eastern, for those last-minute traders out there.

I sort of want to join the finaegling, but I also don't want to risk too much mana here. If I make a limit order and someone shoves through it, then I shouldve put more money in, but then I would have lost more money, and then that's just a risk loop

Astonishing question from mathematical perspective. YES holders have incentive to keep percentage lower (more primes in relative terms) and NO holders have incentive to keep percentage higher (less primes in relative terms).

@VonGadke betting the market to exact percentage with limit orders at the moment of closing is the way to win probably.

@ProjectVictory That's right and that's actually what I intended to do. The only issue with this approach is that one needs to hold a large amount of money at hand at all times, which can be tricky.

bought Ṁ65 NO

I believe there is an equilibrium around x=25 where the prime density function equals the actual percentage. Betting down to there.

opened a Ṁ200 NO at 28% order

@SentientTree There are a few ways to do this which yield slightly different answers, I just did a convolution of a gaussian kernel (sigma=5) with the discrete prime density function. I have limit orders at x=23 and x=28 because it should be in that range regardless, between the primes 23 and 29.
