Prediction markets in Wisconsin
Our status for Wisconsin: In litigation. The state and a prediction market operator are actively in court, and no order blocking the operator is in force. Wisconsin's suits against five prediction markets sit in federal court awaiting remand rulings, alongside CFTC, operator, tribal and voter cases.
Latest action (Other development, Oct. 17, 2026): A voter, Joseph Giganti Sr., filed a federal civil-rights suit against Elections Commission members challenging the view that buying election contracts could disqualify him from voting (date per DeFi Rate's docket tracker).2
We track 8 lawsuits involving Wisconsin. Federal appeals from Wisconsin go to the Seventh Circuit, where an appeal on the question is pending. Full record: prediction market laws in Wisconsin.

“No restriction found” means we know of no court order, regulator action or platform notice stopping it in Wisconsin; 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.
