This year's filing deadline for candidates running for the U.S. House of Representatives in Alaska was June 1, 2026. 

This year is the third year that the election for Alaska's At-Large Congressional District will use a top-four primary system. In a top-four primary, candidates run in a single primary election, regardless of party affiliation. The four candidates who receive the most votes advance to the general election. In the general election, voters use ranked-choice voting (RCV) to select the winner.

This year had the second-highest number of candidates running for the district since 2014. Fifteen candidates — four Democrats, three Republicans, two Libertarians, five nonpartisan, and one undeclared — are running for the district. Twelve candidates ran in 2024, 22 ran in 2022, six ran in 2020, seven ran in 2018, seven ran in 2016, and six ran in 2014.

Among the candidates is Rep. Nicholas Begich (R). As a result, the district is not open this year. An incumbent has run for re-election in the district every year since 2014.

Begich is running in a contested primary this year. An incumbent has run in a contested primary for the district every year since 2014.

Democratic and Republican candidates filed to run in the primary, meaning the district is not guaranteed to either party.

Alaska is holding a U.S. House primary on Aug. 18, 2026.
