Very confusing. Polymarket doesn't allow US use/users. How are folks in the US participating on Polymarket? (VPNs and the like reportedly don't help either due to KYC policies.)

Cryptocurrency. Even if it is a traceable crypto like usdt, it doesn't seem to be enforced.

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

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

its funny, tells you it barely works, and its a good meme.

Successful project imo.

It's not. But also a lot of those stats thrown around are misleading.

If the average no costs less than 73 cents, but the 73% of all polymarkets resolve to No, that would imply that the nothing-ever-happens strategy here is profitable. Are you claiming that it is profitable? Or are one of those premises incorrect?

Edit: conversely, if the average no costs _more_ than 73 cents, but the 73% of all polymarkets resolve to No, that would imply that an everything-always-happens strategy is profitable (neglecting slippage)

Are you willing to pay $.27 for that perspective? Sounds like we have a market!

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.

Don’t be gullible enough to fall for this bad math. Say 70% of the time it resolves to ‘no’, you still don’t make money by blindly choosing ‘no’. Guess why? Hint: This strategy is also described with the macabre analogy: picking up pennies in front of a steamroller. Do you want to pick up pennies in front of a steamroller?

Whether it's pennies in front of a steamroller will depend on the entry price, EV, time left to resolution and many other variables.

Though I agree it's bad math, even if 70% resolve to no, there's a high variance among all of them, and to know whether it's a good bet or not... you have to do your DD on that particular market. Even if you follow the Kelly criterion, randomly choosing bets will probably tank your bankroll sooner or later.

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

What happens if you flood the market with a bunch of implausible bets like "sun won't rise tomorrow"? Sure, you might try to filter that out with some sort of "seasoning" period (ie. don't buy new markets), but then that means more time for arbitrageurs to correctly price the market, depriving you of any price advantage you might have had.

There are quite a few of those, my favourite: https://polymarket.com/event/will-jesus-christ-return-before...

If you put all your money on no, you get 4% if you win, and if Jesus comes back and you lose, money won't matter.
