Quick answer

Available (as of 3 October 2026). Kalshi and the Polymarket US app accept eligible Florida residents, and Florida has taken no enforcement action against them. Kalshi's and Polymarket US's minimum age is 18; we recommend 21+. Federal appeals courts split in 2026, at a preliminary stage, on whether states can apply gambling laws to sports event contracts; Florida's circuit hasn't ruled. Trade on sports, the 2026 Florida governor and Senate races, hurricane landfalls, the FIFA World Cup, and economic events — with no Florida state income tax on winnings. For broader context, our sister site has every legal venue ranked (opens in a new tab), and you can read a deep Kalshi review (opens in a new tab) before you sign up.
