This market will resolve according to the winner of the Republican Primary for Governor of Oklahoma, scheduled to take place on June 16, 2026. Resolution will be based on the overall winner of the primary, including any potential second round or run-off. 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.
Mike Mazzei holds a clear lead in trader assessments for the August 25 Republican primary runoff in Oklahoma’s open 2026 gubernatorial race, driven primarily by President Trump’s endorsement and strong performance among the party’s conservative base. Mazzei and Attorney General Gentner Drummond finished first and second in the June 16 primary with 25.5% and 25.9% respectively, advancing past Chip Keating and other challengers in a fragmented field. Recent independent polling shows the runoff essentially tied at 44% each among likely Republican voters, though markets price in Mazzei’s advantages in self-funding, Trump-aligned turnout, and messaging on taxes and education. The race remains sensitive to final-week mobilization ahead of the August 25 contest.
