Trader consensus on Polymarket heavily favors Democrats sweeping control of both congressional chambers at 49.5%, driven by persistent leads in generic ballot polling averages—such as Rasmussen's March 26 survey showing Democrats ahead 45%-42% and broader averages around +4 to +6 points—which signal a likely House flip from the current Republican majority amid historical midterm penalties for the president's party. The 36.5% odds on Republicans holding the Senate with a Democratic House reflect the GOP's structurally favorable Senate map, where they defend fewer vulnerable seats per Sabato's Crystal Ball March ratings, though recent YouGov polls indicate tightening races. Primaries begin this spring, with economic conditions and turnout as key swing factors ahead of November 3.

A party will be considered to have 'control' of the House of Representatives, if they win a majority of voting seats.
A party will be considered to have 'control' of the Senate if they have more than half of the voting Senate members, or half of the voting Senate members and the Vice President.
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 Democrat 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 control of the House is ambiguous given the above rules, this market will resolve according to the party affiliation of the first Speaker of the US House who is selected following the 2026 United States midterm elections.
If control of the Senate is ambiguous given the above rules, this market will resolve according to the party affiliation of the first Majority Leader of the US Senate who is selected following the 2026 United States midterm elections.
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 winners of the House and Senate in the 2026 United States midterm 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.
