Worst calibrated market ever?
Oct 1, 2025

What market have you seen which had the highest probability of resolving YES but ending up resolving NO (or vice versa)? Bonus points if you believe that traders were making a poor analysis (and not just unlucky). Extra bonus points if the market had many traders.

Ok I think I found the worst one

Interestingly, this guy predicted the next pope months before the election https://x.com/pope_predictor/status/1893436282656669720

So it's not like nobody could've known.

On 9/29/23, next shutdown in 2025 was at 0.1%. It was all on 2023 or 2024. While I it was reasonable to expect a shutdown before 2025, this was still way way overconfident. I bought it up to 1.9%, then chickened out and sold back to 0.7%. Should have had more faith in my analysis.
401 traders overall, 86 traders in the 2025 option.
