House Control in 2026: Democrats Win the Majority

Democrats won control of the House in the November 3, 2026 midterm elections, according to an NPR analysis of Associated Press race calls (November 4, 2026). Some close districts, including several in California, kept counting after election night, so the final seat total comes from each state's official canvass.

All 435 voting seats in the US House of Representatives were on the ballot on November 3, 2026. A party that wins 218 seats has a majority of the full chamber. Vacancies and unresolved contests can temporarily change the number needed for an operating majority, but 218 remains the familiar benchmark when all seats are filled.

Why 218 matters

The House has 435 voting members. Half is 217.5, so 218 seats form a majority. That majority affects the election of the Speaker, committee control and the chamber's ability to organize when the new Congress begins.

The Clerk of the House maintains the official member and vacancy records for the current Congress. Membership can change during a Congress, so check the Clerk's member page for the current party split.

What voters decide on November 3

Each district elects one representative. The national control total is the sum of those separate district outcomes. A close contest in one district can therefore matter just as much to the chamber count as a result in a much larger state.

Unofficial results begin after local polls close. They can change as officials add eligible mail ballots, provisional ballots and corrected returns. A projected result is distinct from the official canvass and certification.

Why some House races take longer

California permits election officials to process vote-by-mail ballots before Election Day, but it also accepts eligible ballots under the deadlines in state law and conducts a post-election canvass. Large numbers of mail ballots and close district margins can extend the count. Other states have different receipt, cure and canvass schedules, so there is no single national moment when every House contest becomes final.

The same distinction matters for market settlement. A contract may use an identified media decision desk, an official result or certification. Read the exact rules. The settlement guide (opens in a new tab) explains those possible triggers once without repeating them here.

The House control markets

Polymarket US lists "U.S. House Midterm Winner". Its rules use results from state election authorities and the House itself, and its rule for a tied result is different from the Senate market's, so read it to see how it settles. Kalshi lists House race markets too. The exact wording on each market page decides when and how it settles.

How the markets settled: Kalshi settled its "Will Democrats win the House in 2026?" market Yes on November 4, 2026 at 1:02 a.m. ET, and Polymarket US resolved its "U.S. House Midterm Winner" market for the Democrats by November 5.

When the new House begins

The Twentieth Amendment sets congressional terms to begin at noon on January 3. For members elected in 2026, that means the new House term begins on January 3, 2027. Organization and swearing-in occur as the new Congress convenes.
