Minnesota becomes first state to ban prediction markets
Minnesota became the first state to ban prediction markets such as Kalshi and Polymarket, with Gov. Tim Walz signing a law that takes effect August 1. The law targets platforms that let users bet on outcomes in politics, sports, culture, policy, and other events.
The ban is already headed into a federalism fight. The CFTC sued to block the law, arguing prediction markets are federally regulated derivatives markets and that Minnesota is intruding on federal authority.
Minnesota officials frame the issue as gambling regulation, not financial innovation. Supporters say these markets can bypass state gambling safeguards, create addiction risks, and invite self-dealing in politics and sports.
The industry’s counterargument is that a state-by-state ban will not eliminate demand. Polymarket told NPR the law conflicts with the federal framework, while critics of the ban argue it may reduce competition and push users toward offshore platforms.
Strategically, this could become a test case for whether prediction markets are treated more like financial exchanges or gambling apps. The outcome will shape who controls the rules: federal commodities regulators, state gambling authorities, or Congress through new legislation.
Are prediction markets useful information tools that need federal oversight, or gambling products that states should be able to ban?
