Trader consensus on Polymarket positions Dan Cox as the clear frontrunner to win Maryland's Republican gubernatorial primary on June 23, with implied probabilities reflecting his strong grassroots mobilization among conservative voters, built from his 2022 upset victory over the establishment-backed candidate in the attorney general primary and prior Trump endorsement. Ed Hale trails closely as a self-funded businessman who switched from Democrat to Republican, announcing his lieutenant governor pick Tyrone Keys in February and drawing a recent endorsement from local outlets amid criticisms of Governor Wes Moore's tax policies. Both leaders skipped Maryland's first Republican primary debate in late March, signaling confidence, while former Governor Larry Hogan's low odds align with his decision against reentering; early voting begins June 11, with no public polls yet available to gauge turnout in this crowded field.
