Mary Peltola’s entry into the race against incumbent Dan Sullivan has kept the 2026 Alaska Senate contest highly competitive, with traders assigning near-even probabilities amid ranked-choice voting and a top-four primary scheduled for August 18. Peltola’s substantial fundraising edge, including over $6.9 million raised since April compared to Sullivan’s roughly $2 million, combined with her prior statewide victories and grassroots organizing, has supported her narrow market lead. Sullivan benefits from incumbency advantages and Alaska’s Republican lean, though limited primary opposition and ballot complications involving another candidate named Dan Sullivan have added procedural uncertainty. Recent polls reflect this balance, with results fluctuating within a few points and no decisive separation emerging ahead of the general election.
