Control of Alaska's U.S. Senate seat decides who represents the state's interests in Congress for the next term.

The outcome influences Arctic policy, fisheries and energy regulation, and the narrow Senate majority math at the federal level.

Dustin Darden, Ann Diener, Dan Sullivan, Mary Peltola, Richard Grayson, and Sid Hill are the named contenders on the ballot.

Sullivan is the incumbent Republican; Peltola is a recent statewide Democratic officeholder with strong Alaska Native support; other candidates mix local prominence and political newcomers.

Polling and turnout patterns in Anchorage, Mat-Su, and rural Bush communities drive raw vote shares across the state.

Fundraising, national party attention, Alaska Native and resource-industry endorsements, and ranked-choice vote transfers after the top-four primary determine who gains majority support.

Top-four primary results this summer will narrow the field and reveal which candidates pick up second-preference viability.

Watch fundraising filings, major Alaska Native corporation endorsements, oil-and-gas headlines, and televised debates for polling shifts ahead of the November 2026 ranked-choice general election.
