Texas chatbots keep Talarico ahead while markets lean harder his way
The chatbot panel was steady this week, but Grok split from the other major models and markets stayed more favorable to James Talarico.

A steady week
The chatbots picked Democrat James Talarico most often in the Texas Senate race this week, with 47 percent of answers. Republican Ken Paxton followed at 39 percent, and Libertarian Ted Brown was at 14 percent.
That was little changed from Oct. 1. None of the chatbot, market or polling numbers moved enough over the week to call it a shift. The difference from last week is that the story is less about movement and more about the gap between the chatbot panel and the betting markets.
The prompts were asked as a voter in Texas. The race is now in the general election phase, with the November election 26 days away.
Grok was the outlier
Most chatbot products put Talarico first. Claude Sonnet 5 picked him in 53 percent of answers, Gemini 3.1 Pro in 50 percent, Gemini 3.6 Flash in 50 percent, GPT-5.4 mini in 58 percent, and GPT-5.5 in 43 percent.
Grok went the other way. Grok 4.5 picked Paxton in 63 percent of answers and Talarico in 38 percent. That made Grok 4.5 the model farthest from the panel’s top pick, by 25 points. Grok 4.3 also put Paxton first, at 60 percent.
Brown’s chatbot support was uneven. GPT-5.5 picked him in 33 percent of answers, Gemini 3.6 Flash in 25 percent and Gemini 3.1 Pro in 20 percent, while several other models picked him rarely or not at all.
Markets are more Talarico-friendly
Prediction markets gave Talarico a 66 percent chance, compared with his 47 percent share of chatbot answers. That is a 19 point gap. Markets gave Paxton a 36 percent chance, close to his 39 percent chatbot share.
The polls were closer to the chatbot panel. The polling average put Talarico at 49 percent of the vote, Paxton at 44 percent and Brown at 3 percent. The latest poll ended Sept. 26, 12 days ago, so the polling picture is recent but not brand new.
Brown is where the chatbots and polls differ most after Talarico’s market gap. The chatbots picked Brown in 14 percent of answers, while polls put him at 3 percent of the vote.
What to watch
Watch whether Grok keeps favoring Paxton while the rest of the chatbot panel keeps Talarico first. That model split is the clearest disagreement inside the chatbot results.
Also watch whether the next polls narrow or widen the 19 point gap between Talarico’s chatbot share and his market chance. With the general election 26 days away, fresh polling would matter more than another quiet week of chatbot movement.

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”: The paragraph suggests future polls would narrow or widen the gap between Talarico's chatbot share and his market chance, but polls are a separate, third lens in this data and have no direct bearing on the ai-to-market gap. A reader could be misled into thinking polling data resolves or explains that gap.
