Resolution Criteria
This event is resolved via two parallel markets – one for each major party’s chance at winning the U.S. House of Representatives in the 2026 midterm elections. Each market resolves to Yes if that party wins a majority of U.S. House seats as a result of the 2026 general election, and No if they do not:
- Democrats: Resolves Yes if the Democratic Party gains or retains control of the House by winning at least 218 of the 435 House seats in the November 3, 2026 elections (i.e. a majority when the 120th Congress convenes in January 2027). Otherwise resolves No.
- Republicans: Resolves Yes if the Republican Party wins at least 218 seats (and thus a majority) in the 2026 House elections. Otherwise No.
If neither party alone wins an outright majority (for example, in the extremely unlikely scenario that third-party/independent candidates prevent both Democrats and Republicans from reaching 218 seats), then both markets would resolve to No – as neither party would “win the House” on its own. The outcome will be verified by official election results and the party composition when the new House convenes (sources such as the Clerk of the House or Library of Congress roll call data).
