Trader consensus on Polymarket prices Ken Paxton at 63.5% to win the Texas Republican U.S. Senate primary runoff on May 26 against incumbent John Cornyn (34.5%), reflecting Paxton's edge in a late-March GQR poll (47%-42%) among GOP primary voters. Following the March 3 primary where neither secured a majority, Paxton's hard-right appeal and CPAC endorsement have sustained momentum despite heavy establishment spending against him exceeding $60 million. Cornyn's incumbency and Senate leadership role provide fundraising advantages, but his perceived moderation alienates the Trump-aligned base. President Trump's delayed endorsement remains a pivotal uncertainty, with historical Texas GOP runoffs often hinging on base turnout and late endorsements. Early voting starts February 17.

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.
