Minnesota Gov. Tim Walz has signed the nation’s first law banning prediction market sites from operating in the state, the most far-reaching crackdown on massively popular services like Kalshi and Polymarket.
It comes as states confront a growing standoff with the Trump administration over how to regulate the industry, which allows people to bet on virtually anything.
The new state law makes it a crime to host or advertise a prediction market, which it defines as a system that lets consumers place a wager on a future outcome, like sports, elections, weather, live entertainment, someone’s word choice and world affairs.
The prohibition extends to services supporting prediction markets, like virtual private networks, that could allow consumers to disguise their location and get around the ban.
It would force prediction market sites like Kalshi and Polymarket to leave the state, or face possible felony charges. The law takes effect in August.


You can’t legislate morality. If you make gambling and drugs illegal they just go underground and become worse problems and foster a criminal underclass/organized crime that becomes a much bigger problem.
Better to keep them legal and put sensible controls on them, emphasis on sensible obviously that’s not what we have going on here. Outside of our freedom on marijuana in some states now at least when you don’t consider how anybody that drives a car can be arrested for impaired driving even if they’re totally sober from the marijuana. If they have smoked in the past week or two. That’s another story though.
