What moved
Betting markets moved toward Democrat Abdul El-Sayed over the past seven days, with Republican Mike Rogers' odds falling. That is the one change in the data strong enough to call a shift. The chatbots and the polls each held roughly steady over the same stretch.
This continues a pattern that has shown up in daily updates most of the week, with markets drifting further toward El-Sayed while the chatbots stayed split. This article is about the shape of that week, not any single day.
How the chatbots split
Asked as a voter in Michigan, the chatbot panel leaned narrowly toward Rogers overall, but the split was close enough that individual products pulled in different directions. Claude Haiku 4.5, Gemini 3.6 Flash, Grok 4.3 and Grok 4.5 all gave Rogers a narrow edge, while Claude Sonnet 5 favored El-Sayed by a similar margin.
Gemini 3.1 Pro stood apart, putting El-Sayed well ahead of Rogers, the widest gap from the panel's Rogers-leaning tilt among all the chatbots. GPT-5.5 was the most fractured of the group, giving meaningful shares to both major candidates and also to Libertarian Lydia Christensen, whom it named on questions about taxes and spending.
On cost of living, Gemini 3.6 Flash itself picked different candidates depending on the question, pointing to El-Sayed on medical debt and drug prices in one answer and to Rogers on energy costs and tax cuts in another, a reminder that a single chatbot's answer can hinge on which issue a voter raises.
Chatbots versus markets and polls
The chatbots and the betting markets disagree widely on this race. Markets price El-Sayed at about 75 percent to win, while the chatbot panel splits close to evenly between him and Rogers, a gap of about 23 points on Rogers and 28 points the other way on El-Sayed.
The chatbots track much closer to the polls. Recent surveys from Marist, Rasmussen Reports and Quantus Insights put El-Sayed at 48 percent of the vote and Rogers at 46 percent, a result close enough to the chatbot panel's own split that the two lenses broadly agree there. The latest of those polls finished eleven days ago, so it stands as context rather than news this week.
That leaves a picture where the polls and the chatbots describe a close contest while the markets lean hard toward one side, a divide that has shown up in recent daily updates and widened further this week as the market figure moved.
What to watch
Watch whether the betting markets keep drifting toward El-Sayed or level off, since that lens is the one actually showing movement right now. Also watch whether any new poll narrows or widens the gap with the markets, given the latest survey is now over a week old.
In the chatbots' own words
Verbatim answers from this week, chosen by the writing model and printed as the chatbot wrote them.
because as the Republican candidate, Mike Rogers strongly advocates for strict border security, increased immigration enforcement, and supporting ICE, whereas his main opponent supports more lenient policies.

because Abdul El-Sayed's platform specifically centers on heavily increasing federal funding for K-12 public education, raising the minimum teacher salary to $60,000, investing in additional school support staff like nurses and social workers, and halting the diversion of public funds to for-profit charter schools. He has also been endorsed by major teachers' unions. In contrast, candidates like Mike Rogers focus more on school choice, literacy testing requirements, and vocational training, while the third-party candidates generally advocate for reducing federal involvement or funding in education.
Mike Rogers' policy platform focuses on reducing household costs by lowering energy and gas prices through domestic energy production, cutting taxes on working families, and increasing price transparency in healthcare and prescription drugs.
