All 435 House seats are on the ballot November 3, 2026. Republicans need 218 for a majority; Democrats need a net gain of three seats to take the chamber.

The map in broad strokes

Most districts are safe for one party after redistricting cycles in 2022–2024. Control will hinge on a few dozen competitive seats in:

  • Suburban Philadelphia and New York (Long Island, Hudson Valley)
  • Central California and the Inland Empire
  • Atlanta's northern suburbs and coastal Georgia
  • Phoenix and Tucson media markets
  • Colorado's Front Range and several Midwestern Obama-Trump-Biden swing counties

What midterm history suggests

The president's party often loses House seats. The size of that loss depends on economic mood, candidate scandals, and whether the out party recruits strong challengers. In 2022, Republicans gained the majority but underperformed some wave expectations.

Special elections and vacancies

Occasional special elections before November can signal enthusiasm, but they are not perfect predictors. Check the dashboard map on this site for current officeholders and any vacant seats marked in the source data.

Forecasting responsibly

District-level polling is sparse. Analysts combine presidential results by district, fundraising reports, and expert ratings. No single poll "calls" the House, look for broad patterns across regions instead.
