Brown's chatbot share grows
Chatbots answering as an Ohio voter this week leaned further into Sherrod Brown for the Senate special election. His share of chatbot answers rose over the past seven days, while Republican Sen. Jon Husted's share fell over the same period.
The betting markets moved too. Husted's price fell over the week even as Brown's standing firmed up, a shift large enough to count as real movement rather than noise.
Polling did not move. The three most recent polls, averaged, still show a closer contest than either the chatbots or the markets do, but no new survey arrived this week to change that picture.
Where the chatbots land
Every chatbot in the panel picked Brown first this week, so there is no outlier pulling against the group. The spread in how strongly they favor him is still wide. Claude Sonnet 5 gave Brown the largest share of its answers, while Claude Haiku 4.5 gave him barely a third, putting Husted and Bill Redpath closer behind.
Several chatbots, including Grok 4.3 and Grok 4.5, pointed more answers to Redpath on questions about taxes and cost of living, with Grok 4.5 naming him as the candidate most consistently focused on tax cuts and spending reductions. Husted still drew chatbot support on federal taxes and public safety questions, with Gemini 3.6 Flash and GPT-5.5 citing his record on taxes and law enforcement funding.
Chatbots, markets and polls split on Husted
The gap between the chatbots and the other two lenses is widest on Husted. His share of chatbot answers is 28 percent, below his 38 percent standing in the betting markets and his 43 percent share in recent polls.
Brown shows a different pattern. Chatbots give him a smaller share of answers than the betting markets give him in win probability, but a larger share than his current polling average, meaning the chatbots sit between the two other signals rather than clearly apart from either.
Redpath draws more chatbot attention than his polling number would suggest, while Greg Levy draws less. Neither has a market figure in the data, so there is no market comparison for them.
What to track next week
Watch whether Husted's chatbot share keeps falling or stabilizes, since it fell sharply this week while Brown rose slightly more. Watch too whether a new poll narrows or confirms the gap between the close recent surveys and the wider lead the chatbots and markets now give Brown.
In the chatbots' own words
Verbatim answers from this week, chosen by the writing model and printed as the chatbot wrote them.
Sherrod Brown — Brown has built his political brand around economic populism and household affordability. As the Cook Political Report noted, Brown functions more as the incumbent in this race, while the appointed Husted is a comparative newcomer. Throughout his Senate tenure he chaired the Senate Banking Committee and consistently pushed consumer-protection, wage, and anti-inflation measures aimed at lowering costs for working- and middle-class Ohioans, making his record the clearest match for a voter prioritizing reduced household expenses and economic stability.
