Trump's endorsement of Mike Mazzei has emerged as the dominant factor elevating his implied probability to 74.9% in the Oklahoma Republican gubernatorial primary runoff market ahead of the August 25 contest. Mazzei, a former state senator and financial adviser, advanced from the June 16 primary alongside Attorney General Gentner Drummond after both topped a crowded field that included Chip Keating and Charles McCall. Recent polling and campaign finance reports show Mazzei holding a narrow edge, reinforced by his focus on tax cuts, education reform, and business growth. Drummond's platform emphasizes cost-of-living issues and tribal relations, yet trader consensus reflects Mazzei's stronger momentum entering the final days of the runoff campaign.

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.
