Already priced in.

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.

If this seems interesting for you remember that if you are putting $100 in a 99 to 1 bet you need to win 100 times to get $100 but only need to loose 1 time to loose $100.

And the chance of losing at least once in a 99% sure bet after 100 rounds is around 60%. Even if you reduce to 30 rounds it still is around 30%.

This may seem smart at first glance, but the math doesn't really checks out.

Turkey reported high winrate until Thanksgiving

Falling victim to the classic fallacy. So sad

We call it a "black turkey event", nobody saw it coming.

I think we've collectively DDoSed it. I'm getting a 504 timeout. The author [page]( https://github.com/sterlingcrispin ) is there on github, but I can't even find his full list of his repos to confirm it's still there (I also get a 504 on that).

GitHub is down yet again. Guess they forgot to tell their AI “make no mistakes” while vibecoding.

I was about to say “first Microsoft service to reach zero 9s of uptime”, but then I realized, it’s Microsoft… GitHub is definitely not the first

Basically arbitraging human imagination. People love coming up with fantastical concepts because they get attention, but the more exciting a market is, the less likely it is to actually happen. Reality is usually boring.

Well, that's why things aren't priced uniformly, isn't it?

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

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

What's the data situation like if you wanted to backtest a model like this? Is it easily accessible?

No, data situation is bad, at least for market making - you need to scrape the orderbook yourself to be able to do any realistic backtesting. And even then, it's hard to know whether other bids at the same price are ahead of you or behind you in the queue.
