Introducing the 2026 Senate Interactive Map

The 2026 Senate Interactive Map is now available. 

Republicans won control of the U.S. Senate by gaining four seats in the 2024 election. That gives the party 53 seats, although one will be vacant until January 13. Jim Justice is expected to be sworn in on that date after his term as Governor of West Virginia ends.

35 seats are up in 2026, 22 of which are held by Republicans. This includes special elections in Florida and Ohio. Sen. Marco Rubio (R) is expected to resign after being confirmed as Secretary of State, while J.D. Vance will become vice president on January 20. The governors of those two states will appoint interim replacements who will serve until the special elections.

Democrats will need to gain four seats in 2026 to retake control.

First Look

These are very preliminary initial ratings compiled after a few informal discussions with forecasters. This will be updated, and ultimately replaced with a consensus forecast, as actual expert ratings become available.

Incumbent Party

For regular 2026 elections, Republicans hold 20 of the 33 seats. There will also be two special elections (Florida and Ohio); both those seats are held by Republicans.
