Quick answer: Bitcoin price contracts are listed on CFTC-regulated exchanges — Kalshi, Polymarket US and OG — which accept Florida residents (status: Available, as of 3 October 2026).

These are federally regulated derivatives, not sportsbook bets, so they are available to Florida residents without a state gambling licence.

Bitcoin Betting in 2026: The Legal U.S. Guide

You can trade Bitcoin price contracts in the U.S. — including Florida — on CFTC-regulated exchanges (status in Florida: Available, as of 3 October 2026). Polymarket and Kalshi both list binary BTC contracts that pay $1 per share if Bitcoin's reference price closes at or above a defined strike by a deadline. The contracts are settled in cash on a published reference rate; they're not the same as owning spot BTC or trading a perpetual future.

Settlement

Most BTC contracts settle on a published reference rate at the resolution timestamp. The CME CF Bitcoin Reference Rate (BRR) is the most commonly cited source for U.S. exchanges; some markets use a different fix. Always read the resolution-source line on the individual market page — the choice of fix can materially change the outcome on a close strike.

Where the trade-offs are

Versus spot BTC: a binary contract is a leveraged expression of a single binary view, with capped downside (the price you pay) and capped upside ($1 per share).
Versus perpetuals: no funding rate, no liquidation risk — you can only lose what you paid for the share.
Versus options: no theta or vega between trade and resolution. The trade-off is you don't capture continuous moves.

Florida-specific notes

BTC contracts on Kalshi and Polymarket US are available to Florida residents. Florida has no state income tax, so the only tax filing is federal. Note that the IRS hasn't issued guidance on how event contracts are classified, and that a BTC price contract is not the same as holding bitcoin. Talk to a CPA who has handled both.

Not financial, legal, or tax advice. Crypto event contracts can resolve at zero. Tax treatment differs from spot crypto — talk to a CPA familiar with both.

Frequently asked questions

Is Bitcoin betting legal in Florida?

Available (as of October 3, 2026). Bitcoin event contracts on Kalshi and Polymarket US are CFTC-regulated and available in Florida.

What price feed do BTC markets settle on?

It varies by market. The CME CF Bitcoin Reference Rate is the most commonly cited source for U.S. exchanges; always check the individual market's rules block.

Is this taxed differently than spot crypto?

Probably, but the IRS hasn't issued guidance on how event contracts are classified. A price contract isn't spot crypto, so crypto rules don't automatically apply. A CPA familiar with both is your best resource.

Can I trade BTC perpetuals on Polymarket?

Polymarket's U.S. product is binary event contracts, not perpetual futures. Perpetuals exist on other venues outside the prediction-market category.

How are fees calculated on a BTC trade?

Both Kalshi and Polymarket US use formula-based fees that scale with how close the contract is to 50¢. Fee schedules are at kalshi.com/fee-schedule and docs.polymarket.us/fees.

Is trading Bitcoin event contracts the same as buying Bitcoin?

No. You never hold the coin — you buy a contract that settles at $1 or $0 based on whether a stated price condition is met by the deadline.
