Is Kalshi legal in Florida? Is Polymarket? Sports contracts, the Seminole compact and DeSantis (2026)
Kalshi is available in Florida, sports contracts included, and the state has not taken action against it. But Governor DeSantis has questioned it and the Seminole Tribe holds exclusive sports betting rights. What you can trade, the risks, Polymarket US, and taxes.
Yes, Kalshi is legal to use in Florida, including its sports contracts. As of October 2026 Florida had not issued a public cease-and-desist order or filed a lawsuit against Kalshi. The state's only legal online sportsbook is run by the Seminole Tribe, though, and that exclusivity is where the tension lies.
As of 21 October 2026. The Kalshi app checks your location and shows only what you can trade.

The Seminole compact
Under its gaming compact with Florida, the Seminole Tribe holds the exclusive right to offer sports betting statewide, through Hard Rock Bet. Prediction markets offering sports contracts compete directly with that monopoly, and tribes elsewhere have taken prediction markets to court; in California, tribes won a key appeals ruling against Kalshi in September 2026 (is Kalshi legal in California?).
What Florida's leaders have said
- Governor Ron DeSantis said on CNBC in February 2026 that he was not sure Kalshi's sports contracts squared with Florida's arrangement with the Seminole Tribe.
- The legislature considered broad gambling bills in the 2026 session, including one that would have created felony penalties for illegal gambling operations; neither became law.
- No enforcement action against Kalshi had been made public as of October 2026.
Florida is a state to watch: it has a powerful tribal gaming partner and a governor who has signalled doubts, but it has not acted so far (is Kalshi legal?).
What Floridians can trade
- Sports: Dolphins, Buccaneers, Jaguars, Heat, Magic, Lightning and Panthers games, and championships (Super Bowl odds; NBA championship odds).
