U.S. Rep. Byron Donalds dominates trader consensus at 86.5% implied probability for the Republican gubernatorial primary winner on August 18, 2026, fueled by President Trump's early endorsement, consistent polling leads exceeding 40 points among GOP primary voters, and a record $22 million first-quarter fundraising haul announced this week—outpacing all non-incumbent challengers. Recent surveys from early March confirm Donalds approaching majority support, solidifying his frontrunner status in the open-seat race succeeding term-limited Gov. Ron DeSantis. Investor James Fishback trails at 9.5% with Gen Z appeal via online outreach, while Lt. Gov. Jay Collins and others linger below 2%, as no major shifts have emerged in the past 30 days beyond Donalds' financial edge and poll dominance. Upcoming debates or additional endorsements could influence the crowded field.

If no 2026 Florida Republican Gubernatorial 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 Florida Republican Party; however, an overwhelming consensus of credible reporting may suffice.
