What will happen at the 67th IMO 2026 Shanghai, China? Each answer will resolve independently of each other. Feel free to add your own questions. Other questions may include country ranks, country medals, specific individual performances, cutoffs, solve rate, AI performance, etc.

In the unforeseen circumstance that IMO 2026 does not take place, everything will resolve N/A

  • Update 2026-04-24 (PST) (AI summary of creator comment): Cutoff markets have been resolved N/A, as the creator has decided not to keep them open before day 2 is over to avoid stressing contestants.

@Wintersfan For clarification, I will use the definition from this market

I have decided to N/A cutoff markets, because having these before day 2 is over may stress the contestants.

I might open a separate cutoff market but only after IMO day 2 is over.

@Wintersfan Revived this market as a throwback for the 2025 market :)

@DottedCalculator Very funny.

I need your guys' opinion: should I include unofficial russia scores for the country rank bets?

@Wintersfan I think Russia is official this year?

@DottedCalculator Oh wow, I am not aware of that, we will see later

@RaymondChristopherTanto

These are the stats I compiled from 2005-2025, a problem 1/2/4/5 that has <25% solve rate used to be common but is very rare nowadays.

(I hope I compiled the stats correctly lol, I did it manually. Again, a solve is defined as at least 5 points)
