Why the answers differ
A sportsbook takes the other side of each bet and keeps what bettors lose.3 It needs a license from the state. A prediction market is an exchange that matches users with each other and takes a fee,3 and the large ones are regulated by the CFTC, whose jurisdiction over trading on those exchanges federal law calls exclusive.4 That is the platforms’ case for offering sports contracts nationwide; by the 2025 Super Bowl, Kalshi offered them in all 50 states, including states without legal sports betting.5
States answer that sports event contracts are sports bets by another name; Massachusetts, for one, says Kalshi’s closely resemble wagers at licensed sportsbooks.6 Federal appeals courts have split, 1 for the platforms and 2 for the states, and 3 petitions now ask the Supreme Court to decide: see the circuit split.
Age limits
Kalshi and Polymarket US accept customers from 18,78 while most states set the gambling age at 20 or 21, a gap critics including the NCAA have raised.9 See how old you have to be. If gambling is causing you harm, call or text 1-800-GAMBLER.
