Trump's endorsement of Mike Mazzei has emerged as the dominant factor shaping trader consensus in the Oklahoma Republican gubernatorial primary runoff, positioning him as the clear favorite ahead of the August 25 contest against Gentner Drummond. Mazzei, a former state senator and financial adviser, advanced from the June 16 primary alongside Drummond after both topped a crowded field that included Chip Keating and Charles McCall. Recent developments, including a televised debate and Mazzei's release of negative drug test results amid campaign scrutiny, have reinforced market positioning, with traders assigning low probabilities to all other listed candidates who failed to reach the runoff. The implied probabilities reflect skin-in-the-game assessments of endorsement impact and runoff dynamics rather than polling ties.
