For this question I'm working on https://polygains.com

What other question would you like to be backtested? This one is fairly easy

For every bucket of probability, what is the chance it resolves correctly?

For example, for markets that are between 60 and 70, is it the case that around 65% of them resolve to yes?

I guess you want to take a certain time before out finishes, so focus on sports.

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.

>you get 4% if you win,

This locks up your money in the meantime, right? If so, considering the fed funds rate is 3.64% (and you can probably get higher rates on stablecoins), a huge chunk of those "winnings" is going to be eaten up by the opportunity cost of the money.

You forget that Polymarket is just a casino, and the house always wins.

For example, recent events show that any bet can be selectively disputed by arbitrary reason ("we found insiders", "we found this immoral/illegal", etc.).

And for perpetual events - there is not a single week without a hack (https://www.web3isgoinggreat.com/)

> What happens if you flood the market with a bunch of implausible bets like "sun won't rise tomorrow"?

Who does "you" refer to in this sentence? Polymarket itself?

I'm pretty sure if Polymarket itself decides it wants to screw you, you're gonna lose no natter what your strategy is.

That presumes that there are people selling into new markets at 0.5 without thinking about the actual odds.

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

Except that the mere existence of the market with the question posed for people to consider, probably activates the availability heuristic[1], causing people to overestimate the likelihood.
