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

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)
