This market will resolve according to the party that controls the House of Representatives following the 2026 U.S. House elections scheduled for November 3, 2026.
House control is defined as having more than half of the voting members of the U.S. House of Representatives.
If the outcome of this election is ambiguous given the above rules, this market will remain open until the Speaker of the House is selected following the 2026 U.S. general election, at which point it will resolve to the party the Speaker is affiliated with at the time of their election to that position. If the elected Speaker does not caucus with any listed party this market will resolve “Other”.
Determination of which party controls the House after the 2026 U.S. House elections will be based on a consensus of credible reporting, or if there is ambiguity, final federal and/or state election authority certification or other final official determination of the 2026 election results.Trader consensus heavily favors Democrats (83.5%) to regain House control in the November 2026 midterms, driven by persistent Democratic leads of 2–6 points in generic ballot polling averages from Nate Silver, RealClearPolling, and others, including fresh surveys through late April showing Democrats at 44% versus Republicans at 42%. Record Republican retirements—36 versus 20 Democrats—have created numerous open seats, eroding GOP incumbency advantages in battleground districts amid historical midterm penalties for the president's party under Trump. Republicans defend a slim majority with limited margin for error, though upcoming primaries and potential shifts in turnout or economic conditions could narrow the gap.
