Polymarket US vs sportsbooks in Florida
Why Polymarket US is legal in Florida when sportsbooks are not
Florida's sportsbook market is a one-operator monopoly under the Seminole compact, leaving Floridians without the competitive multi-book market other states enjoy. Polymarket US offers a legal alternative on sports outcomes: a CFTC-regulated exchange, launched for US customers in December 2025, whose sports-led contract catalog is available to Florida residents under federal derivatives law rather than the state compact.

What the fees look like
Exchange pricing means the odds are set by traders and the fee is a disclosed, price-dependent charge per contract — not a margin buried in the line by a monopoly operator. For Floridians whose only sportsbook option is a single house setting its own prices, that transparency is the point.
| Venue | Fee per contract | Total taker fee |
|---|---|---|
| Kalshi | 1.75¢ | $1.75 |
| Polymarket US | 1.50¢ | $1.50 |
Exchange-side taker fees per each venue's published formula (rate × contracts × price × (1 − price), Kalshi rounds the order total up to the next cent). Fees peak at 50¢ and shrink toward the extremes. Most quoted cross-venue “arbs” are negative-EV after these fees — the taker-fee breakeven on a Kalshi/Polymarket pair is roughly 3.5–4¢.
