Mary Peltola’s commanding primary performance, where she captured nearly 50% of the vote and led incumbent Sen. Dan Sullivan by more than eight points after full absentee counting, has driven trader sentiment toward her 65.5% implied probability of winning the November general election. Alaska’s top-four primary system and ranked-choice voting in the general election favor well-known candidates with broad appeal, and Peltola’s success as the state’s first Alaska Native in Congress, combined with strong fundraising and independent voter support, positions her as the frontrunner in this toss-up contest. Sullivan retains advantages as the two-term Republican incumbent focused on energy development, but his narrower primary showing and the presence of a similarly named challenger have contributed to the current market gap. Recent candidate forums on resource policy underscored the race’s stakes for Senate control.
