Byron Donalds holds a commanding lead in the August 18, 2026, Florida Republican gubernatorial primary thanks to President Trump’s endorsement and a substantial fundraising edge, leaving Jay Collins and Paul Renner positioned as the main contenders for second place. James Fishback, a 31-year-old investor running an outsider campaign with notable online visibility among certain activist networks, has consolidated trader expectations for third place. Recent ballot challenges against Fishback failed, and his polling remains low overall but exceeds most of the remaining field. A surge by Renner or another lesser-known candidate, unusually high turnout among specific voting blocs, or last-minute shifts in endorsements could alter the ordering for third, though the frontrunner’s dominance limits realistic pathways for major disruption before primary day.
