State Treasurer Stacy Garrity commands overwhelming trader consensus at 94.4% to win Pennsylvania's Republican gubernatorial primary on May 19, reflecting her incumbency advantage, statewide name recognition, and March Trump endorsement that solidified her frontrunner status against a sparse field including 2022 nominee Doug Mastriano (1.2%) and longshot John Ventre (3.5%). Recent Republican voter registration drives target the May 4 deadline amid no primary polls indicating challenger momentum, while Garrity focuses campaign events on critiquing Democratic Gov. Josh Shapiro. Though odds exceed 90%, a late Mastriano base turnout surge, scandal, or procedural ballot disputes could alter the outcome before polls close.

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.
