Gentner Drummond leads Polymarket trader consensus at 50% implied probability to win the Oklahoma Republican gubernatorial primary on June 16, buoyed by his consistent edge in the most recent independent polling from late January—36% support among likely Republican primary voters—driven by high name recognition as state attorney general and strength among frequent primary participants. Mike Mazzei holds 26.4% following a mid-April surge in prediction markets tied to his heavy television advertising and self-loans exceeding $2 million, positioning him as a potential runoff threat in this crowded nine-candidate field requiring a majority for outright victory. Charles McCall and Chip Keating trail at 12.5% and 8.5%, respectively, bolstered by personal funding but lagging in recent surveys; recent candidate forums have highlighted policy differences on taxes and education without shifting polling dynamics.
