Resolves at the party that the first prime minister elected after the next general election is from. Update 2026-03-04 (PST) (AI summary of creator comment): If a hung parliament results in no government being formed and a snap election is called without any government (including a minority government) forming in the meantime, the market will resolve based on the PM after that subsequent election.
