Republican traders price a trifecta with Senate supermajority after the November 3, 2026 midterms at just 2.1% implied probability, reflecting the 2026 Senate map's structural barriers: Republicans defend 23 seats to Democrats' 12, with race ratings from Cook Political Report and Sabato's Crystal Ball showing few tossups and most Democratic-held seats safe. Starting from a current 53-47 GOP edge, achieving 60 seats would require holding all vulnerable incumbents like Maine's Susan Collins while flipping nearly every Democratic seat up—contrary to historical midterm penalties on the president's party, averaging six Senate losses since 1950. Recent developments, including GOP concerns over battlegrounds and a Democratic elections task force launch, reinforce hold-the-line forecasts over expansion, though a massive economic surge or Democratic scandals could theoretically shift dynamics.

This market will resolve based on the results of all Congress elections, including special elections, that are scheduled to occur in November 2026 as of October 31, 2026.

A party will be considered to have 'control' of the House of Representatives if it wins a majority of voting seats.

A candidate's party is determined by their ballot-listed or otherwise identifiable affiliation with that party at the time the 2026 United States midterm 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 that they most recently expressed their intent to caucus with at the time the 2026 United States midterm elections are 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.
The resolution source for this market is the Associated Press, Fox News, and NBC. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.
