Kalshi's Sports Betting Markets Just Got Banned in Michigan — Here's What That Means for Prediction Markets

WHY IT MATTERS

Prediction markets are platforms where people can bet on the outcome of real-world events — like who wins an election or whether a team wins a game. Think of them like a stock market, but instead of buying shares in companies, you're buying contracts that pay out if something happens. Kalshi is one of the biggest legal prediction market platforms in the U.S., and it recently started offering sports-related contracts. The problem is that sports betting is already tightly regulated state by state, and Michigan decided Kalshi's sports markets look too much like gambling, which requires a special state license. This matters because it shows how tricky it is for new financial products — including crypto-based prediction markets like Polymarket — to operate when existing laws weren't designed for them.
