Trader consensus on Polymarket heavily favors Texas Attorney General Ken Paxton at 66.5% to win the Republican Senate primary runoff against incumbent Senator John Cornyn on May 26, with Cornyn at 31.5% and others negligible after failing to advance from the March 3 first round where neither candidate exceeded 50%. Recent polls, including a Democratic-aligned Senate Majority PAC survey released yesterday showing Paxton up by 5 points and an earlier Impact Research poll with him at 53%-37%, underscore his momentum among GOP primary voters drawn to his populist stance and Trump-aligned base support. Cornyn, facing establishment critiques, has sought endorsements from Rep. Wesley Hunt and President Trump, whose decision remains pending and could sway turnout in this high-stakes intra-party contest.

If no 2026 Texas Republican Senate Primary takes place, this market will resolve to "Other".
The resolution source for this market will be the first announcement of the results from the Texas Republican party, however an overwhelming consensus of credible reporting may suffice.
