Mike Mazzei holds a strong trader consensus lead in the Oklahoma Republican gubernatorial primary runoff due to his Trump endorsement, heavy self-funding exceeding $10 million, and momentum from the June 16 primary where he and Attorney General Gentner Drummond finished in a virtual tie at roughly 26 percent each. The August 25 runoff follows a crowded nine-candidate field in which other contenders like Chip Keating and Charles McCall fell short, consolidating support behind the top two. Recent polls show a near-dead heat around 44 percent each, with Drummond edging among women voters and Mazzei among men, though prediction markets price in Mazzei's structural edges in a solidly Republican state where the winner will face Democrat Cyndi Munson in November. The outcome hinges on turnout among primary voters and any late shifts before the runoff.
