"Texas Senate Race 2026: Markets Price a Democratic Win at 67.5% While a Forecast Model Still Backs Paxton"
Texas has not elected a Democrat to statewide office in three decades, which is what makes the current betting on its Senate race so striking. On Polymarket, the market for a Democratic win in the 2026 Texas Senate race is priced at 67.5%, against 32.5% for a Republican win. That is not a coin flip, and it is not a polling average. It is traders putting real money behind the idea that Democrat James Talarico will beat Republican Ken Paxton on November 3, in a state where that outcome has not happened in a generation.
The market move itself is worth noting, because it has been steady rather than sudden. The Democratic price climbed from 64.5% on the evening of October 26 (UTC) to 67.5% by the evening of October 27, with hundreds of thousands of dollars changing hands in a single day and millions in total volume behind the two sides of the race. Markets are not polls, and they can be wrong in both directions, but a price this high, moving in one direction, is a claim that deserves to be checked against the other evidence rather than dismissed.
The polls, taken on their own, lean the same way as the market, but by much less. The University of Houston's Hobby School surveyed 2,000 likely voters between October 10 and 14 and found Talarico ahead 48% to 46%, with Libertarian Ted Brown at 3%. Emerson College Polling, surveying 1,000 likely voters between October 17 and 19, found the same 48% to 46% margin, narrowing to 49% to 48% once undecided voters were asked which way they lean. A polling average compiled by Pollsmax across 63 polls put Talarico ahead 48.1% to 45.5%, a lead of 2.6 points, while a Rasmussen poll on October 21 had the race tied at 45% each. Emerson also notes a slow trend in Talarico's favour: his support has inched up by about a point a month since August, from 46% to 48%, while Paxton has hovered between 46% and 47%.
So why does a forecast model built from those same polls still favour the Republican? Pollsmax's model, updated on October 27, gives Paxton a 55.3% chance of winning and projects a vote split of 50.5% to 49.5% in his favour, rating the race as tilting Republican. The reason is fundamentals: this is an open seat in a state Donald Trump won by 13.7 points in 2024, and models give weight to that history precisely because polls in Texas have a habit of flattering Democrats. The model is, in effect, betting that the state's partisan gravity reasserts itself on Election Day, while the market is betting that this year's polls are telling the truth.
There is one more detail that could decide which of them is right, and it is small enough to miss. Emerson points out that if support for the Libertarian candidate melts before Election Day, Paxton will probably gain, because those voters are mostly independents or Republicans; if it holds, Talarico benefits. A race decided by two points can easily be decided by where three points of third-party support go, and by whether the undecided voters break the way the leaners suggest.
I lean toward the market's direction but not its confidence. A polling lead that shows up across pollsters, in a race where the Democrat's numbers have been creeping up for months, is real evidence, and the market's direction reflects it. But a 67.5% price implies a race that is nearly settled, and nothing about a two-point polling lead in Texas, against a model that still favours the Republican and a three-decade history of Republican statewide wins, justifies that much certainty. My own number is 55% for a Talarico win: a genuine lean, not a prediction I would bet the house on. If I am wrong, the likeliest reason will be the familiar one in Texas politics, that the polls overstated the Democrat once again and the state's fundamentals won out. The answer arrives on November 3, and it will settle more than one argument at once: about this race, about whether Texas polls can be trusted, and about whether a market price of 67.5% was insight or enthusiasm.
