What is the difference between a sportsbook and a prediction market?

A sportsbook takes the other side of each bet and keeps what bettors lose, under a state license. A prediction market is a federally regulated exchange that matches users with each other and charges a fee, which is why platforms argue state gambling law does not reach them.

Prediction markets in Montana

Our status for Montana: Enforcement, no lawsuit. State officials have sent cease-and-desist letters or taken other enforcement steps, but we found no active litigation. Montana's Gambling Control Division twice ordered Kalshi to stop sports contracts; Kalshi's federal suit ended in a stipulated dismissal under which the state holds off enforcement for now.

Latest action (Court order, Sept. 21, 2026): The court dismissed the case on a joint stipulation filed Sept. 17, 2026: claims against the five commission members with prejudice, and against the attorney general, a Division official and the Division without prejudice. The defendants agreed not to begin enforcement over Kalshi's event contracts until Kalshi's Ninth Circuit rehearing bid in KalshiEX v. Assad is resolved, after which the attorney general's side must give 30 days' written notice.²

We track 1 lawsuit involving Montana. Federal appeals from Montana go to the Ninth Circuit, which ruled for the states on Aug. 28, 2026. Full record: prediction market laws in Montana.

“No restriction found” means we know of no court order, regulator action or platform notice stopping it in Montana; it is not a finding that it is legal there.

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.
