**James Talarico holds a narrow lead over Ken Paxton in the 2026 Texas U.S. Senate race on prediction markets, with implied probabilities recently in the low-to-mid 60s percent range on Polymarket and Kalshi.** Recent Paxton audio leaks and recordings, including comments on campaign challenges and associations, have weighed on his position and supported Talarico's edge. Talarico's strong fundraising and polling advantages among independents and on cost-of-living issues have also factored in, though public polls show a tighter contest (RCP average around +2 points) than market pricing. His brief mid-October campaign absence due to flu caused a short dip in odds before recovery upon his return. With early voting beginning October 19 and Election Day November 3, traders are watching for further developments on candidate momentum, turnout, and any additional revelations in the closing weeks that could shift the closely contested race.
