Alaska chatbots still favor Sullivan as the split with betting markets holds steady

A week without much change
Alaska voters who asked a chatbot about the Senate race this week got largely the same answer they would have gotten seven days ago. Neither the chatbots, the betting markets nor the polls moved enough to call it a shift, even though the underlying numbers wiggled a little in both directions.
Republican Sen. Dan Sullivan remained the chatbots' top pick overall, while Democrat Mary Peltola's chatbot share ticked up slightly and her number in the betting markets ticked down. Neither move was large enough to count as a real change, and the race stayed where it has been for days.
Where the chatbots split
Most chatbots leaned toward Sullivan this week. Claude Haiku 4.5, Grok 4.3, Grok 4.5, Gemini 3.6 Flash, Gemini 3.1 Pro Preview and GPT-5.4 mini all gave him the larger share of their answers, with Grok 4.3 at 58 percent to Peltola's 40 percent.
Claude Sonnet 5 broke the other way, giving Peltola 51 percent to Sullivan's 49 percent, which makes it the outlier on the panel this week. GPT-5.5 came out almost exactly split, with Peltola at 50 percent and Sullivan at 49 percent.
The reasoning behind those picks varies by issue. Gemini 3.1 Pro Preview pointed to Sullivan's record on Arctic security and military readiness when asked about a hawkish foreign policy, while Grok 4.3 pointed to Peltola's record on environmental protections when asked about resource development. Claude Sonnet 5 named Peltola as the candidate most focused on subsistence and tribal issues, citing her history as the first Alaska Native elected to Congress.
Chatbots, markets and polls still disagree
The gap between the chatbots and the betting markets remains wide. The chatbots put Sullivan around 53 percent and Peltola around 44 percent, while the markets price Peltola as about a 75 percent favorite and Sullivan at roughly 26 percent, a gap of nearly 28 points on Sullivan and 30 points on Peltola.
Polls tell a closer story. A recent average of three polls, the latest from Trafalgar Group with field work ending September 24, puts Sullivan at 45 percent and Peltola at 44 percent, essentially a tie. The chatbots are close to that polling level for Peltola, but they put Sullivan higher at about 53 percent.
That leaves the chatbots sitting much closer to the polls than to the markets this week, even as none of the three lenses moved enough to call it news.
What to watch
With 19 days left until the November 3 general election, watch whether the betting markets' lean toward Peltola narrows or widens, since that gap with the chatbots has been the defining feature of this race for weeks. A new poll replacing the three-week-old Trafalgar Group number could also move the close Sullivan-Peltola polling margin.

Mary Peltola — Mary Peltola, a Democrat, was the first Alaska Native elected to Congress , and her campaign has centered on protecting traditional subsistence resources, noting that "Growing up, Alaska was a place of abundance. Now, we have scarcity," Peltola said, citing salmon, large game, and migratory birds that used to fill freezers as being harder to find. Her identity as an Alaska Native leader and legislative focus on fisheries/subsistence issues make her the candidate whose record most directly centers on protecting subsistence access, ANCSA interests, and tribal self-determination compared to her opponents in this race.
