Prediction markets in Arizona
Our status for Arizona: In litigation. The state and a prediction market operator are actively in court, and no order blocking the operator is in force. A federal injunction bars Arizona from prosecuting Kalshi; Arizona has asked the Ninth Circuit to lift it for sports contracts.
Latest action (Other development, Sept. 14, 2026): Arizona moved in the Ninth Circuit to summarily vacate the injunction as to sports-event contracts and remand the election-contract issues; no ruling had been reported.2
We track 5 lawsuits involving Arizona. Federal appeals from Arizona go to the Ninth Circuit, which ruled for the states on Aug. 28, 2026. Full record: prediction market laws in Arizona.

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.
