Availability by country

Prediction markets in the United States

Of the 57 platforms we review, 12 are open to US residents, 6 with restrictions and 26 exclude them. For 13 the published terms do not say either way.

Event contracts are regulated federally by the Commodity Futures Trading Commission (CFTC). Exchanges it designates can offer them nationally, but several states have challenged sports contracts, and a platform’s availability can differ by state. Offshore platforms generally block US residents.

Each line reports what the platform’s own terms say, with the source we read and when. It is not legal advice, and a platform can still refuse an individual account. Last checked 5 Nov 2026.

By state

Court orders and state actions change what is open where. Each state has its own page, with what the state has done and every platform’s status there.
