The 2026 United States Senate elections are scheduled to be held on November 3, 2026, with 33 of the 100 seats in the Senate being contested in regular elections. In these elections, voters will elect candidates to six-year terms that begin on January 3, 2027, and expire on January 3, 2033. Senators are divided into three classes whose terms are staggered so that a different class is elected every other year. Class 2 senators were last elected in 2020 and are up for election in this cycle.

Two special elections are also scheduled for November 3, 2026. One will be held in Ohio to fill the remaining two years of former Senator JD Vance's unexpired term following his resignation to become vice president of the United States, and one will be held in Florida to fill the remaining two years of former Senator Marco Rubio's unexpired term after he resigned in 2025 to become United States Secretary of State. With the election of John Thune as leader of the Republican Conference, this will be the first election year since 2006 in which the Republicans are not led by Mitch McConnell.

Partisan composition

All 33 Class 2 Senate seats and two Class 3 seats are up for election in 2026. Class 2 currently consists of 20 Republicans and 13 Democrats. If vacancies occur in Class 1 or 3 Senate seats, additional special elections could be scheduled for November 3, 2026.

Democrats are defending two seats in states won by Donald Trump in 2024 (in both cases, by less than 3 percentage points): Michigan, where incumbent Gary Peters is not running for reelection; and Georgia, where the incumbent is Jon Ossoff. Michigan elected Democrat Elissa Slotkin to the Senate in 2024 by 0.3 percentage points; Georgia did not have a Senate election in 2024, although in the most recent Senate election, in 2022, Democrat Raphael Warnock won by three points in a runoff. ^{[1] [2]}

Five incumbent Democratic senators represent states won by Kamala Harris by single-digit margins in 2024: New Hampshire's Jeanne Shaheen, Minnesota's Tina Smith, Virginia's Mark Warner, New Jersey's Cory Booker, and New Mexico's Ben Ray Luján. ^[1] Shaheen and Smith are not running for reelection. ^[3]

Susan Collins's seat in Maine is the only seat being defended by a Republican in a state that Kamala Harris won in 2024. ^[4] Republican Thom Tillis of North Carolina is retiring ^[5] from the Senate in a state won by Trump by a single-digit margin in 2024. ^[1]

The 2026 Senate map is considered favorable to Republicans. In this cycle, Democrats are defending 13 seats, while Republicans are defending 22 seats. The makeup of the seats up for reelection means that Republicans are heavily favored to retain their Senate majority. Only two Republican-held seats are considered competitive by most rating groups, and Democrats need to flip a minimum of four seats to win a majority. Furthermore, two to four Democratic-held Senate seats are considered vulnerable. ^{[6] [7] [8]}

Change in composition

Each block represents one of the one hundred seats in the U.S. Senate. "D#" is a Democratic senator, "I#" is an Independent senator, and "R#" is a Republican senator. They are arranged so that the parties are separated and a majority is clear by crossing the middle.

Predictions

Several sites and individuals published predictions of competitive seats. These predictions looked at factors such as the strength of the incumbent (if the incumbent was running for reelection) and the other candidates, and the state's partisan lean (reflected in part by the state's Cook Partisan Voting Index rating). The predictions assigned ratings to each seat, indicating the predicted advantage that a party had in winning that seat. Most election predictors used:

• "tossup": no advantage
• "tilt" (used by some predictors): advantage that is not quite as strong as "lean"
• "lean": slight advantage
• "likely": significant, but surmountable, advantage
• "safe" or "solid": near-certain chance of victory

Potentially competitive seats

These are seats which polling and predictions currently have listed as being at least somewhat close.

Republican incumbents

Two of the four Senate races expected to be the most competitive feature Republican incumbents in Maine (Susan Collins) and North Carolina (Thom Tillis). ^[22] Maine's 2026 race is regarded as being competitive due to the state's blue lean, but Collins previously kept her seat during cycles favorable to Democrats nationally (2008 and 2020). ^{[23] [24]} North Carolina's race is also considered competitive since the state has a slight right lean, and Tillis never won a majority of votes in his races. ^{[25] [26]} On June 29, 2025, Tillis announced that he would not seek a third term. ^[16] In July 2025, Democratic former Governor Roy Cooper announced his candidacy for the open seat; Cooper is the best-polling of all potential Democratic candidates for this seat. ^[27]

Incumbents in Ohio (Jon Husted), Texas (John Cornyn), and Alaska (Dan Sullivan) are also expected to have somewhat competitive races. ^[22] Joni Ernst, the incumbent in Iowa, has announced that she will not seek a third term. ^[11] The incumbent in Nebraska (Pete Ricketts) could also face a competitive race with the entrance of independent Dan Osborn, who ran against Republican Deb Fischer in the Class I race in 2024. Osborn was the most successful challenger of a Republican-held seat during the 2024 election cycle, having lost by only 6 points compared to Kamala Harris's loss by 20 points in Nebraska in the concurrent presidential election. Democrats did not contest the seat in 2024, and it is unclear whether they will do so in 2026.

Democratic incumbents

The other half of the Senate races expected to be the most competitive are those in Georgia and Michigan. ^[22] Georgia's incumbent Democratic senator (Jon Ossoff) is expected to be in a highly competitive race, though not as competitive as it could have been since Republican Governor Brian Kemp declined to run for the seat. ^[28] Ossoff narrowly beat out former Senator David Perdue in 2021 to win his first term. ^[29] In Michigan, senator Gary Peters has announced his retirement, setting a scramble for the state with an even PVI score. ^[30]

The seats in Minnesota (vacated by Tina Smith), and New Hampshire (vacated by Jeanne Shaheen) are expected to be only marginally close races—especially the latter, with popular former Republican governor Chris Sununu declining to run. ^{[20] [31]} But Sununu's brother John E. Sununu is considering a run for the Senate seat he lost to Shaheen in 2008, with his decision expected in November. Despite this, Republican former United States Senator from Massachusetts and U.S. Ambassador to New Zealand and Samoa Scott Brown announced his candidacy for the open seat; Brown was the Republican nominee in 2014, narrowly losing the general election to Shaheen. ^[32]

One-term Republican Tommy Tuberville previously said he planned to seek reelection, ^[156] but announced on May 27, 2025, that he would instead run for governor of Alabama in 2026. ^[9] He was elected in 2020 with 60.1% of the vote.

Former Navy SEAL Jared Hudson, state Attorney General Steve Marshall, Congressman Barry Moore, businessman Jeremy Spratling, and fuel company CEO Rodney Walker have announced their candidacies for the Republican nomination. ^{[39] [41] [43] [157] [158]}

Potential Republican candidates include former Secretary of State John Merrill, former state Department of Veterans Affairs Commissioner Kent Davis, ^[159] state House Speaker Nathaniel Ledbetter, and former Congressman from Alabama's 5th District Mo Brooks, who was also a candidate for Alabama's other U.S. Senate seat in 2022. ^[160]

On the Democratic side, small business owners Dakarai Larriett and Kyle Sweetser and chemist Mark Wheeler II have all announced campaigns. ^{[40] [44] [45]} Sweetser, a former Republican, also spoke at the 2024 Democratic National Convention. Former U.S. Senator from this seat Doug Jones (2018–2021), who was defeated for reelection by Tuberville in 2020, is seen as a potential Democratic candidate. ^[161]

Sportscaster and former University of Alabama Crimson Tide football head coach Nick Saban has been cited as a potential candidate for Senate, though his party preference is unknown. ^[162]

Notes

1. Majority control in an evenly divided Senate is determined by the Vice President of the United States, who has the power to break tied votes in their constitutional capacity as President of the Senate; accordingly, Senate control requires 51 seats or 50 seats with control of the vice presidency.
2. Both independent senators (Bernie Sanders of Vermont, and Angus King of Maine) caucus with the Democrats.
