U.S. Rep. Byron Donalds dominates trader consensus at 86.5% implied probability to win Florida's Republican gubernatorial primary on August 18, 2026, propelled by President Trump's early endorsement, a perfect alignment with his policy priorities, and commanding poll leads—recent surveys show him ahead by 40 points among GOP primary voters, nearing majority support. A record $22 million fundraising quarter reported this week further cements his frontrunner status, reflecting strong donor confidence amid perceptions of his conservative record on taxes, border security, and economic growth. Challenger James Fishback holds 9.5% as a younger, provocative alternative generating online buzz despite weak initial fundraising, while others like Jay Collins trail far behind due to limited momentum and name recognition in the crowded field. Upcoming debates and endorsements could influence the closely watched race.

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.
