The 2026 midterm elections are scheduled to be held on November 3, 2026. This market will resolve according to the number of seats held by the Republican Party in the US House of Representatives as a result of the 2026 midterm elections. This market will resolve based on the results of all US House of Representatives elections, including special elections, that are scheduled to occur in November 2026 as of October 31, 2026. If a required runoff for any such election could change the market’s outcome, the market will remain open until that runoff is conclusively called by this market’s resolution sources. A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all US House of Representatives elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.Trader consensus favors Republicans holding below 190 House seats at 26%, reflecting persistent Democratic leads on the generic ballot averaging D+6 in May polls, historical midterm penalties for the president's party averaging 26-seat losses, and a record 36 Republican retirements creating vulnerable open seats in battleground districts. Recent redistricting court rulings have bolstered GOP maps in key states, supporting secondary odds around 190-204 (25-37% combined) over deeper losses, amid uncertainty from President Trump's declining approval and special election Democratic overperformance. Primaries beginning this summer and economic trends could consolidate support toward narrower GOP deficits if turnout favors incumbents or widen them on anti-administration sentiment.
