U.S. House Elections

Elections to the U.S. Senate will happen on November 3, 2026. Thirty-three of the 100 seats in the chamber are up for election and another two seats are up for special election.

Of the 33 regularly scheduled general elections in 2026, Democrats control 13 and Republicans control 20.

Looking ahead at the 2026 general elections, Democrats need to gain a net of four seats to win a majority in the chamber. Meanwhile, Republicans can only lose two seats and retain a majority in the chamber.

As a result of the 2024 general elections, Republicans won a 53-45 majority in the chamber. Additionally, two independents caucus with the Democrats. Heading into the 2024 general election, Democrats had a 47-49 majority with four independents. Three of those independents caucused with the Democrats, and one other counted towards the Democratic majority for committee purposes.

Democrats could not lose any seats and retain a majority in the chamber. Meanwhile, Republicans needed to gain a net of two seats and retain a majority in the chamber. In the 2024 general elections, Republicans gained a net of four seats.

Four incumbents—all Democrats—lost re-election in the general elections in 2024.

Democrats are defending two seats in states that Donald Trump (R) won in the 2024 presidential election. Those states are Georgia and Michigan. Republicans are defending one seat in a state that Kamala Harris (D) won in the 2024 presidential election. That state is Maine.

As of November 29, 2025, eight U.S. Senate incumbents—four Democrats and four Republicans—are not running for re-election in 2026.

Two special elections will also happen on November 3, 2026. One special election is to fill the last two years of the six-year term that Marco Rubio (R-Fla.) was elected to in 2022. The other special election is to fill the last two years of the six-year term that J.D. Vance (R-Ohio) was elected to in 2022.

Those elected to the U.S. Senate in the regularly scheduled elections on November 3, 2026, will begin their six-year terms on January 3, 2027.
