Trader consensus on Polymarket heavily favors Texas Attorney General Ken Paxton at 69.5% implied probability to win the Republican U.S. Senate primary runoff against incumbent Sen. John Cornyn on May 26, reflecting Paxton's dominance among the GOP base after neither candidate cleared 50% in the March 3 first-round primary. Recent CPAC endorsement of Paxton and a March 28 straw poll there showing him at 67% to Cornyn's 21% have boosted sentiment, underscoring grassroots preference for Paxton's hardline stance on border security and criticism of Cornyn as establishment-aligned. A March 20 poll indicated Paxton leading absent a Trump endorsement, which remains pending and could sway undecideds. Cornyn's 28% share draws from institutional support and fundraising edge, while minor candidates trail at 0.1% post-primary elimination. Ted Cruz recently warned the intra-party fight risks weakening the GOP nominee against Democrat James Talarico in November.

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.
