How to Trade in Florida

Everything a Florida resident needs to go from zero to placing their first prediction market trade — and what to know about taxes when you start winning.

Updated

Prediction markets aren't sportsbooks. Contracts trade between traders, prices represent real probabilities, and you can sell your position at any time — even mid-game. If you've only used Hard Rock Bet for Heat or Dolphins games, the model takes a few minutes to wrap your head around, but it's genuinely simpler once you understand the basics — and it opens up markets Hard Rock will never list (hurricane landfall, Florida gubernatorial races, Inter Miami MLS Cup odds, Fed rate decisions).

Florida traders also have a real edge on taxes: no state income tax means your effective rate on prediction market gains is purely federal — whether you're in Miami-Dade, Broward, Tampa, Orlando, or Jacksonville. Below are the two guides that get every new Florida trader started right.

Frequently asked questions

How do I start trading prediction markets in Florida?
Sign up at a CFTC-regulated venue like Kalshi or the US Polymarket app, verify your identity (driver's license + Florida address), deposit via ACH or debit, and place your first Yes/No contract. The whole process takes about 10 minutes if you're 21+ and have ID handy. Florida residents in all 67 counties are eligible.
Do I have to pay taxes on prediction market winnings in Florida?
Yes — federally. Florida has no state income tax, but the IRS treats prediction market gains as ordinary income (or sometimes capital gains, depending on holding period and platform). Operators send you a Form 1099-MISC if your net winnings exceed $600 in a calendar year. We recommend tracking every trade and consulting a CPA familiar with event-contract income.
Can I lose more than I deposit on a prediction market?
No. Every Yes/No contract is fully collateralized — the maximum you can lose on any single contract is what you paid for it. There is no margin, no leverage, and no liability beyond your deposited balance on CFTC-regulated venues.
