Republicans currently hold a narrow House majority near 218-220 seats entering the 2026 midterms. Democratic generic ballot leads of 4-6 points, combined with the historical pattern of midterm losses for the president's party, have driven trader expectations toward net Republican losses of roughly 20-30 seats. Recent special election results and polling trends reinforce this positioning, while mid-decade redistricting in states such as Texas has provided some offsetting GOP map advantages. With the race still five months out, variables including candidate recruitment, fundraising, turnout differentials, and any shifts in national conditions keep probabilities clustered across the sub-200 seat ranges without clear separation.

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.
