Texas GOP Senate primary traders heavily favor Attorney General Ken Paxton at 60.5% over incumbent Sen. John Cornyn at 38.5% ahead of the May 26 runoff, driven by post-March 3 polls showing Paxton leading by double digits, including Impact Research's 53%-37% margin and a tight Senate Majority PAC survey. Paxton's stronger favorability among primary voters, Trump-aligned record, and recent attack ads slamming Cornyn's establishment ties and absences during key votes have widened his edge despite Cornyn's allies spending over $70 million. President Trump's delayed endorsement—tied to SAVE America Act filibuster talks—adds uncertainty, while Rep. Burgess Owens' recent Paxton backing bolsters the challenger; other candidates remain negligible after failing to advance.

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.
