Sikt’s forecast
Sikt gives James Talarico a 62% chance, against 72% on the markets at the time. Latest Sikt Midterm Bench round: Nov 3, 2026.
Sikt’s read
- History favors Republicans. No Democrat has won a Texas Senate race since 1988, and Trump carried the state by about 14 points in 2024.
- The polls favor Talarico. Every final polling average puts him 2.5 to 3.8 points ahead, and the strongest nonpartisan polls are his best (NYT/Siena +7, AtlasIntel +6, SSRS +6, YouGov +4). Only Republican-leaning pollsters show a tie or Paxton up 1.
- The year helps him. Democrats lead the national generic ballot by about 9 points, Paxton carries heavy baggage, John Cornyn has not endorsed him, and Republican leaders have voiced alarm in public.
- What holds Sikt back: Texas polls understated Republicans by three to five points in 2020 and 2024, and the vote still to be cast on Election Day leans Republican. (In the 2018 midterm, though, the polls overstated Cruz.)
- Bottom line: Talarico is a modest favorite, a touch lower than last round. Sikt discounts his poll lead for Texas's record, so it is clearly less sure of him than the market is.
How much will they win by?
Sikt’s middle estimate: Talarico by 2.4 points. Its 80% range runs from Paxton by 3.4 to Talarico by 8.0, so the result should land inside it 8 times in 10. Kalshi's margin markets, at the start of the round: Talarico by 3.0 (Paxton by 2.1 to Talarico by 8.4).
