Trump’s endorsement of Mike Mazzei shortly before the June 16 primary elevated the former state senator and budget secretary into a near-tie with Attorney General Gentner Drummond, who led by a slim margin in the nine-candidate field and advanced alongside him to today’s August 25 Republican runoff. Recent polling shows the contest as close or slightly favoring Mazzei, with one survey indicating a six-point lead amid voter perceptions of Mazzei as the more conservative option. Campaign spending, endorsements from business and conservative groups, and the ongoing test of Trump’s influence in Oklahoma have consolidated trader expectations around Mazzei while leaving Drummond’s path dependent on traditional Republican support. Other listed candidates remain at negligible levels following their earlier elimination.

If no 2026 Oklahoma Gubernatorial Republican Primary takes place, this market will resolve to “Other.”
The resolution source for this market will be the first official announcement of the results from the Oklahoma Republican Party; however, an overwhelming consensus of credible reporting may suffice.
