Mary Peltola’s commanding 99.7% implied probability in the Alaska Senate race stems from her consistent lead in first-choice votes during ongoing ballot tabulation after the November 3 election. With roughly 49% of counted ballots favoring the Democrat and the incumbent Republican trailing by several thousand votes, Peltola sits near the 50% threshold that would avoid ranked-choice voting. Remaining absentee and questioned ballots, combined with minor candidates splitting limited Republican support, reinforce trader consensus that her advantage is unlikely to be overcome before certification on November 25. A reversal would require an unprecedented late surge in Sullivan ballots or shifts in ranked-choice tabulation scheduled for November 18.
