Not the first sketchy Polymarket resolution. It's also worth noting the rules can change on the fly. Earlier this year ISW changed how they map the war in Ukraine by introducing "Russian infiltration areas" where in the past they would have said "Russian-controlled territory". Polymarket updated the rules to say "Russian infiltration areas" wouldn't count if you are betting on a "Will Russia capture X?" market. Great news if you're betting on Ukraine, not so great if you're betting on Russia.
