These are seats, not 2026 match-ups: most primaries are still to come, and some sitting members will not be on the ballot. Sabato’s Crystal Ball rates the districts individually and currently has the Democrats favoured on a small battlefield.

Each party trades as its own contract rather than as a share of one pool, so the two prices are quoted independently and need not total 100%.

How little has to move

With 219 seats against 212, the Republican majority is 1 seat deep. A net loss of 2 hands the chamber over — fewer than the 9 Republican-held competitive districts listed here, which is why the whole chamber turns on a couple of dozen seats out of 435.

Frequently Asked Questions

How many seats are needed to control the House?

218 of 435. The Republicans currently hold 219 and the Democrats 212, with 4 seats vacant, so the working majority is a handful of seats either way.

Are all House seats up in 2026?

Yes. All 435 voting seats are elected every two years, which is why the House can change hands in a single night while the Senate turns over a third at a time.

Why are there no ratings or percentages next to each district?

Because we do not produce them and cannot verify a borrowed set here. Polymarket runs a market on House control, shown above, but none on individual districts. Sabato’s Crystal Ball rates the districts and its assessment of this cycle is linked below; rather than reproduce twelve of its calls without a date on them, the table sticks to which seats are competitive and who holds them.

Can I share a map I have built?

Yes. Open the full interactive map, assign the districts, and use the Share button for a link or embed code.

Control percentages are live Polymarket prices carrying the time they were read, not a forecast produced by this site. Seat counts are the current standing of the 119th Congress and change with each special election.
