Republicans currently hold a 53-47 Senate majority following the 2024 elections, with 35 seats contested in 2026 including special elections in Florida and Ohio. The map features more Republican-held seats overall but includes vulnerable contests in states like Georgia, where Democrat Jon Ossoff faces reelection, and open Democratic seats in Michigan. Generic ballot trends show a typical midterm advantage for the opposition party, while Republican defenses in North Carolina and Maine add uncertainty. Trader pricing reflects this balance, with probabilities clustered around modest net changes that could leave Republicans between 48 and 52 seats depending on primary outcomes, candidate recruitment, and state-level turnout dynamics.

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 Senate as a result of the 2026 midterm elections.
This market will resolve based on the results of all Senate 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.
If a Senate seat is vacant but a corresponding election is not held in November 2026, the seat will be considered held by the party of the seat's most recent incumbent.
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 Senate elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democratic or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the Senate 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 Senate 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.Republicans currently hold a 53-47 Senate majority following the 2024 elections, with 35 seats contested in 2026 including special elections in Florida and Ohio.
