The Florida Governor Republican Primary 2026 is the rare statewide race with a runaway favorite. Byron Donalds, the Trump-endorsed congressman, has turned a nine-name Republican field into a one-man board. Roughly $8.5M in cumulative volume sits across Kalshi and Polymarket, and the live board above ranks every contender from Donalds down to longshots like James Fishback and Jay Collins. The market resolves with the August 18, 2026 primary.
The Florida Governor Republican Primary 2026 has the shape most primary markets never reach this early: a settled one. Byron Donalds, the four-term congressman who locked up Donald Trump's endorsement in early 2025, has pulled so far ahead that the rest of the nine-name Republican field trades as an afterthought. Roughly $8.5M in cumulative volume has moved across Kalshi and Polymarket, and almost all of the conviction sits on one contract. The live board above ranks the full field; this page covers who is on it, what could shake the order, and how the market settles on August 18, 2026.
Donalds is the chalk, and it is not close. The U.S. Representative for Florida's 19th District became the de facto frontrunner the moment Trump endorsed him in early 2025, and with term-limited Governor Ron DeSantis unable to run again, the seat is open and the endorsement is doing the heavy lifting. On the board above, Donalds sits in the 90s while no other Republican has climbed out of the low single digits.
That lopsidedness changes what the market is actually pricing. When a favorite trades this high, the interesting number is not the direction, it is the cross-platform spread. Kalshi and Polymarket both list the Donalds contract, and the gap between the two exchanges is the only place a sharp reader finds movement on the frontrunner. Watch the live board above for where the two platforms disagree on the same name.
The risk to the Donalds thesis is not another candidate out-polling him. It is a structural event: the endorsement getting pulled, a late entrant with national pull, or a qualifying surprise. None of those are priced as likely, which is exactly why the contract sits where it does.
Behind Donalds, the field is a list of names competing for distant-second money. James Fishback, the investor and commentator who built a national profile through media and his firm Azoria, has drawn the most challenger volume on the board, though that interest has not translated into a real price. Jay Collins, the state senator DeSantis appointed Lieutenant Governor in 2025, is the establishment-adjacent name to watch if the governor's wing of the party wants an alternative.
Jimmy Patronis, formerly Florida's Chief Financial Officer and now a member of Congress, rounds out the names with any market footprint. Matt Gaetz, the former congressman, and Casey DeSantis, the First Lady of Florida whose potential candidacy was a recurring storyline through 2025, both appear on the board as longshots rather than active threats. Wilton Simpson, the Agriculture Commissioner, former House Speaker Paul Renner, and Charles Burkett fill out the nine-name field.
The read on every one of these contracts is the same: they are lottery tickets priced as lottery tickets. The board above will reprice them the instant any of them files, drops, or draws a Trump comment, but as the field stands, the challenger tier is a bet on chaos, not on a campaign.
The market resolves with Florida's Republican gubernatorial primary on August 18, 2026. It settles to the candidate certified as the Republican nominee, with the first official announcement from the Florida Republican Party as the source of truth, and an overwhelming consensus of credible reporting able to suffice. Each candidate contract pays $1 per share if that candidate wins the nomination; all others settle at $0. If no 2026 Florida Republican gubernatorial primary takes place, the market resolves to "Other" under platform rules.
