https://x.com/sterlingcrispin/status/2043723823678382254 They admit no returns. But it does seem like a fun project and nowhere does it say anything about returns or profits so not scammy imo just funny meme backed code

When people do find an edge they tend not to share it ;)

> 73% of all polymarkets do resolve to No though. I bet the average price for a no bet across these markets is 73 cents.

71 cents*, the bookie gets a cut either way it goes.

Untrue for polymarket. True for kalshi. No bookie fees on polymarket

Even if a cut isn't taken and there aren't other inefficiencies, any money tied up in long-term predictions is earning 0% instead of whatever the current risk-free rate of return is.

Yes exactly. The bot has zero risk management and I have a strong disclaimer on the github it is essentially a meme. 73% of all polymarkets do resolve to No though. There's a good dataset on huggingface if you wanted to do some data science https://huggingface.co/datasets/SII-WANGZJ/Polymarket_data

Behavioral economics has already answered the question of whether humans are, on average, perfectly rational economic actors. They are not.

To the contrary, there is substantial evidence indicating a meaningful number of humans will mis-estimate the likelihood of uncommon future events.

Does the existence of that knowledge make a slight bias lowering the odd on no? I could fork this and with a 1 line change earn dozens of dollars as long as I don't tell anyone what that secret change is.

No, I think the bias is really just a reflection of how propositions are phrased. We could imagine a mirror-world prediction market that offers all the same propositions, but phrased oppositely: e.g. a market in "person X will die by Y date" becomes a market in "person X will survive until Y date". And in that market, we would see a bias towards propositions resolving as Yes.

Already priced in.

The author also noted: > yes this has to buy below 0.73 long term, the bot has a configurable ceiling set at 0.65 and checks for new markets buying closer to .5 https://x.com/sterlingcrispin/status/2043685362812461436

Of course, once you add a condition like that, the probabilities change....

Well, if the price would be incorrectly set, then bots like this one would make money, which would in sufficient time cause the market to adapt and the average price would change so the bot doesn't work.

That doesn't matter so much when it happens in a place where people can make money from other people's irrationality. Even if there are a bunch of irrational people placing bad bets on uncommon future events, rational people looking to make a buck will take the other side of that bet, until the price is sensible.

The alternative would be that there's a bunch of free money sitting there waiting for someone to decide to pick it up, and nobody is, not even you.

The contrarian bet is fun but I wonder how it actually holds up. Prediction markets do tend to overprice dramatic outcomes, so "always bet no" isn't as dumb as it sounds. Would love to see real P&L over a few months, not just the thesis.

I've backtested this kind of strategy, and it had a good return (like 100% APR), but then I realized it was cheating by knowing when things are going to resolve. Often times it's not clear. Your return depends a lot on how quickly you can get your money out. I never got around to trying a strat that doesn't know the resolution time, which actually has to be manual cause it takes some judgement to pick things that you…
