House Debate And Minnesota Law Showcase Emerging Crackdown On Prediction Markets
On Tuesday, May 19, 2026, Minnesota Governor Tim Walz signed a law banning online prediction market sites from operating or advertising statewide, a move that could trigger felony charges for platforms.[1]
The statute criminalizes hosting or advertising markets that allow wagers on sports, elections, weather, entertainment, specific word choices and world affairs, and it targets services that help users evade the ban, including certain VPN tools.[2] The law takes effect in August 2026 and includes carve-outs for event contracts that function like insurance and for purchases of securities and other commodities.[2]
Minnesota Representative Emma Greenman sponsored the measure and said the state should set gambling rules to protect public safety and children.[2] The law comes as lawmakers and regulators have debated similar limits nationally; the U.S. House recently declined to pass a federal ban despite bipartisan calls for prohibition.[3]
Industry executives warned of immediate legal fights.[2] Kalshi called the ban a "blatant violation" of the law and likened banning prediction markets to banning the New York Stock Exchange.[2] Legal experts and regulators are already litigating the issue: the Commodity Futures Trading Commission has sued several states seeking to override state restrictions, and observers expect constitutional and preemption challenges to Minnesota's statute.[2]
