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 two years. Class 2 senators were last elected in 2020 and are up for election in 2026. With the election of John Thune as leader of the Republican Conference, this will be the first election year since 2006 in which Senate Republicans are not led by Mitch McConnell.

Special elections have been scheduled in Ohio and Florida, following the resignation of JD Vance to become vice president and Marco Rubio's resignation to become secretary of state.

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.[1] 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.[2][3]

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.[2] Shaheen and Smith are not running for reelection.[4] Susan Collins's seat in Maine is the only seat being defended by a Republican in a state that Kamala Harris won in 2024.[5] Republican Thom Tillis of North Carolina is retiring[6] from the Senate in a state Trump won by a single-digit margin in 2024.[2]

The 2026 Senate map is considered favorable to Republicans. Democrats are defending 13 seats, while Republicans are defending 22, a distribution that advantages the GOP in maintaining its majority. Most rating groups identify two Republican-held seats as highly competitive and two others as somewhat competitive. By contrast, Democrats must flip at least four seats to win a majority while defending two highly vulnerable seats and two others viewed as somewhat vulnerable.[7][8][9]

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

Multiple sites and political pundits have published predictions of competitive seats. These predictions have considered 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 typically assign ratings to each seat, indicating the predicted advantage that a party had in winning that seat. Most election predictors use:

  • "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

Maine is the only one of the four Senate races expected to be the most competitive that has a Republican incumbent (Susan Collins).[33] Maine's 2026 race is regarded as competitive due to the state's blue lean, but Collins previously kept her seat during cycles favorable to Democrats nationally (2008 and 2020). Incumbent governor Janet Mills, former deputy secretary of the Maryland Department of the Environment David Costello,[34] and military veteran Graham Platner are running for the Democratic nomination in Maine.[35][36] North Carolina's race is also considered competitive, since the state has a slight right lean, and incumbent Thom Tillis is retiring,[19] having never won a majority of votes in his races.[37][38] In July 2025, former Governor Roy Cooper announced his candidacy for the open seat[39] and went on to win Democratic nomination.[40] That same month, former RNC Chairman Michael Whatley entered the race after Tillis declined to seek reelection and was immediately endorsed by President Donald Trump.[41]

Incumbents in Ohio (Jon Husted), Texas (John Cornyn), Alaska (Dan Sullivan), and Louisiana (Bill Cassidy) are also expected to have somewhat competitive races.[33] Cornyn is facing a primary challenge from Texas Attorney General Ken Paxton. Cassidy is also facing primary challenges from Louisiana State Treasurer John Fleming and U.S. representative Julia Letlow; an incumbent U.S. senator has not lost a primary election in any state since 2012 in Indiana.[m] Former United States senator Sherrod Brown, who lost reelection in 2024, has declared his candidacy in Ohio, while former representative Mary Peltola has also declared her candidacy in Alaska. Joni Ernst, the incumbent in Iowa, has announced that she will not seek a third term.[13]

The incumbent in Nebraska, Pete Ricketts, could also face a competitive race against 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, losing 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 Class I seat in 2024 and are not expected to do so in 2026. In August 2025, the Nebraska Democratic Party endorsed Osborn.[42] Despite this, several candidates have filed for the Democratic primary, raising concerns that their campaigns could split the vote and weaken support for Osborn in the general election.[43]

Democratic incumbents

The other half of the Senate races expected to be the most competitive are those in Georgia and Michigan.[33] 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.[44] Ossoff narrowly beat former Senator David Perdue in a 2021 runoff to win his first term.[45] In Michigan, senator Gary Peters has announced his retirement, setting a scramble for the state with an even PVI score.[46]

The seats in Minnesota (vacated by Tina Smith), and New Hampshire (vacated by Jeanne Shaheen) are expected to be only marginally close races—especially New Hampshire, with popular former Republican governor Chris Sununu declining to run.[25][47] Sununu's brother, former Senator John E. Sununu, announced a run for the Senate seat he lost to Shaheen in 2008.[48] Former United States Senator from Massachusetts and U.S. Ambassador to New Zealand and Samoa Scott Brown has announced his candidacy. Brown was the Republican nominee in 2014, narrowly losing the general election to Shaheen.[49]
