Alaska Senate chatbots stay with Sullivan as markets favor Peltola
This week’s answers held roughly steady, but the chatbots split sharply from betting markets and differed among themselves.

The week held steady
The chatbot panel kept picking Republican Sen. Dan Sullivan in Alaska's U.S. Senate race, with Sullivan at 52 percent of chatbot answers and Democrat Mary Peltola at 45 percent. That was little changed from Oct. 15, and none of the chatbot, market or polling measures moved enough this week to call it a real shift.
The answers were prompted as a voter in Alaska asking about the current November field. Alaska’s August top-four primary is history. Peltola led that primary with 49.5 percent, Sullivan followed with 41.4 percent, and nobody won the Senate seat then. The general election is Nov. 3, 12 days from the data date.
The chatbots did not line up
Most products leaned toward Sullivan, but not all by the same amount. Gemini 3.6 Flash picked Sullivan in 58 percent of answers, Grok 4.5 in 58 percent, Grok 4.3 in 57 percent, GPT-5.4 mini in 51 percent, and GPT-5.5 in 51 percent. Gemini 3.1 Pro preview was nearly even, with both Sullivan and Peltola at about 40 percent.
Claude Sonnet 5 was the main outlier. It picked Peltola in 54 percent of answers and Sullivan in 46 percent, putting it about 8 points away from the panel’s top pick. Claude Haiku 4.5 leaned Sullivan at 48 percent, but gave Peltola 27 percent and also put some answers with Daniel J. Sullivan Jr.
Markets and polls tell a different story
The sharpest split was between chatbots and prediction markets. The chatbots picked Sullivan at 52 percent, while markets gave him a 27 percent chance. That is a 26 point gap. For Peltola, the chatbots were at 45 percent while markets gave her a 75 percent chance, a 30 point gap in the other direction.
The polls were closer to the chatbot panel than the markets were. Polls put Sullivan at 45 percent of the vote and Peltola at 44 percent, based on three polls, with the latest ending Sept. 24. Against those polls, the chatbot panel was 8 points higher for Sullivan and 1 point higher for Peltola.
What to watch next
The key thing to watch next week is whether the split between chatbot answers and markets narrows before the Nov. 3 general election. Markets currently favor Peltola, while the chatbot panel still favors Sullivan. The polls are older standing context now, with the latest poll 28 days old, so any new survey could matter more than another quiet week of chatbot movement.
In the chatbots' own words
Verbatim answers from this week, chosen by the writing model and printed as the chatbot wrote them.
Incumbent Republican Senator Dan Sullivan is a U.S. Marine Corps veteran and member of the Senate Armed Services Committee who has consistently championed a robust U.S. military presence and proactive defense strategy in the Arctic. His legislative record includes pushing for major military infrastructure investments in Alaska, securing statutory requirements for an updated DOD Arctic strategy, and expanding U.S. Coast Guard icebreaking capabilities and missile defense systems to counter strategic adversaries in the region.

Mary Peltola — the Alaska Democratic platform she's tied to calls for "comprehensive federal immigration reform that provides an achievable, humane pathway to citizenship for undocumented people, keeps families together, and improves and modernizes legal immigration systems." This aligns closely with a humane, pathway-to-citizenship approach, in contrast to incumbent Republican Sullivan's more restrictionist record.

A note from the second reader
Claude Sonnet 5 checked this article and published it, but would have framed part of it differently. Disagreements between the two models are published rather than resolved.
On “What to watch next”: The paragraph frames the poll age and market gap as things that could change before the general, which is fair, but it comes close to implying the chatbot number is static while other lenses are more current. A neutral reader might want it noted that the chatbot panel itself showed no significant movement either, rather than singling out polls as the stale lens.
