Mary Peltola wins the Alaska U.S. Senate election in 2026.
Alaska's Senate seat is up for election in November 2026. This resolves if Representative Mary Peltola is officially called as the winner.
Across 6 frontier models answering independently, the panel thinks this is unlikely: the median is 21%.
They do not agree: Qwen puts it at 38% and DeepSeek at 4%, 34 points apart. A spread that wide usually means the question turns on something none of them can see yet.
Money disagrees. The market sits at 74%, so the models are 53 points less confident than people with cash on the outcome — one of the wider gaps in the archive.
Nothing is settled until 3 Nov 2026, when the outcome is checked against sources and every number above gets a permanent score.

Peltola's viability hinges on whether she can replicate her 2022 House coalition in a tougher Senate race against a likely Republican.
- Peltola won her House seat in 2022 via RCV with crossover appeal, but Senate races in Alaska have trended more Republican since Murkowski's 2022 loss to a Trump-endorsed…
- Alaska's RCV system helps Peltola, but the Senate field likely includes a strong Republican (possibly someone like Nick Begich III or a Murkowski-aligned moderate) who…
- Base rate for Democrats winning Senate seats in red-leaning states is low (~15-20%), but Peltola's demonstrated crossover appeal and Alaska's unique RCV system push this…

Depends on Peltola winning Alaska's ranked-choice Senate race against Sullivan and any independents.
- Dan Sullivan is the sitting Republican incumbent and Alaska has trended red statewide in federal races despite RCV.
- Peltola lost her House re-election in 2024, showing declining strength even with her prior crossover appeal.
- Polling and fundraising through mid-2026 would need to show a clear Peltola lead to move this meaningfully above the low 20s.

Peltola must beat incumbent Sullivan in a R+8 state under RCV six weeks out.
- Sullivan (R, elected 2020) is the incumbent; Senate incumbents win ~85% of races and Alaska last elected a Democrat in 2008.
- Peltola’s House wins and Native Alaskan profile make her the strongest possible Dem, yet mid-Sept polling typically still shows her trailing 5–8 points.
- A late poll or RCV simulation putting her first or second with Murkowski-style crossover would move the number most.

It turns on whether Peltola enters and can consolidate anti-Republican votes under Alaska’s top-four primary system.
- Peltola must first become a Senate candidate, survive the August 2026 top-four primary, then beat incumbency-level Republican support in November.
- Alaska elected Peltola statewide in 2022, but she lost her House seat in 2024; Senate wins over established GOP candidates are rare.
- A strong Peltola primary showing or a split Republican field after the August primary would materially raise the odds.

Dan Sullivan holds strong incumbency in red Alaska, and Peltola may not even challenge him after her 2024 House defense.
- Incumbent Dan Sullivan won by 12.7% in 2020 and commands deep institutional support and fundraising in conservative Alaska.
- Peltola first faced a bruising 2024 House reelection, making an uphill statewide jump against a GOP senator highly risky.
- Ranked-choice voting gives Peltola a puncher's chance if the GOP fractures, but Sullivan lacks Palin-style spoiler vulnerability.

Peltola isn't running for Senate; Dan Sullivan holds the seat and no credible candidacy exists.
- Peltola has given no indication of a Senate bid and filed for re-election to the House; the Senate seat is held by Dan Sullivan, who is running.
- Alaska's filing deadline passed in June 2026, so no new candidate can enter; Peltola's name won't appear on the Senate ballot.
- Even a write-in or draft scenario would need to beat Sullivan under ranked-choice voting, which no non-candidate has done in Alaska history.
