U.S. Rep. Byron Donalds dominates trader consensus at 84% implied probability to win the Florida Republican gubernatorial primary on August 18, 2026, propelled by President Trump's endorsement, a record $22 million Q1 2026 fundraising haul reported April 1, and a commanding 46% lead in the April 2 Emerson College poll among likely GOP primary voters—far ahead of rivals. Lt. Gov. Jay Collins trails at 5.5% despite entering the race in January, while investor James Fishback holds 9% amid a crowded field to succeed term-limited Gov. Ron DeSantis. Recent attacks on Donalds over past Democratic registration and donor influence claims have surfaced in late April but failed to dent his polling or market edge, underscoring the wisdom of crowds favoring his incumbency-free momentum and MAGA alignment in this open-seat contest.
