This market will resolve according to the winner of the Republican Primary for Governor of Pennsylvania, scheduled to take place on May 19, 2026. Resolution will be based on the overall winner of the primary, including any potential second round or run-off. If no 2026 Pennsylvania 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 Pennsylvania Republican Party; however, an overwhelming consensus of credible reporting may suffice.

Stacy Garrity's dominant 92.2% implied probability in the Pennsylvania Republican gubernatorial primary market reflects her recent campaign launch as State Treasurer, leveraging incumbency for statewide name recognition, early fundraising leads exceeding $1 million, and endorsements from key GOP figures like state senators. Traders view her as the clear establishment frontrunner, with John Ventre and Doug Mastriano trailing due to limited resources and Mastriano's 2022 general election defeat eroding his viability. Realistic challenges include a high-profile entry by a Trump-aligned outsider like Mastriano formalizing his bid or Scott Perry, shifts in national Republican dynamics, or weak early polling before the May 2026 primary.
