Missouri Cracks Down on Prediction Markets — What It Means for You

Dr. Annelies De Vos · 2026-09-21

Missouri just made a bold move that could change how you bet on sports online. Attorney General Catherine Hanaway sent cease-and-desist letters to six prediction market operators, telling them to stop offering sports event contracts to customers in the state. The companies on the list? Polymarket, Kalshi, Crypto.com, Novig, Underdog, and Robinhood. Hanaway's office argues that these sports contracts are essentially sports wagering under Missouri law. And if that's the case, these platforms need a license from the Missouri Gaming Commission to operate legally. Each company has 30 days to comply. That means they either stop offering these contracts to Missouri residents or face potential legal consequences. ### Why This Matters Prediction markets have exploded in popularity recently. They let you buy and sell contracts based on the outcome of events — everything from elections to sports games. It feels like trading, but for many, it's just another way to bet. Missouri isn't buying the "it's not gambling" argument. The state sees these sports contracts as a way to place wagers, plain and simple. And if you're going to offer that, you need to follow the same rules as traditional sportsbooks. This isn't just a Missouri issue, either. It's part of a larger national conversation about where the line is between financial speculation and gambling. Other states are watching closely. ### What the Companies Are Saying So far, the six operators haven't issued a unified response. But this isn't the first time prediction markets have faced pushback. Kalshi, for example, has been in legal battles before over similar issues. Polymarket has also run into regulatory trouble. The big question: will they fight this in court, or will they simply block Missouri users from accessing sports contracts? Either way, it's a headache for these platforms. ### What It Means for You If you live in Missouri and use any of these platforms, you might soon find that you can't trade sports-related contracts anymore. That's a big shift if you've been using them as an alternative to traditional sports betting. > "This is a clear signal that states are going to treat prediction markets just like any other sportsbook if they offer sports wagers," said one industry analyst. "The days of operating in a gray area are numbered." For now, here's what you should know: - The cease-and-desist applies only to sports event contracts, not other types of prediction markets. - Each company has 30 days to comply. - If they don't, they could face legal action from the state. - This could set a precedent for other states to follow. ### The Bigger Picture Prediction markets have been growing fast, and regulators are struggling to keep up. Some see them as innovative financial tools. Others see them as unregulated gambling. Missouri is clearly in the latter camp. This move could push more states to take similar action. It could also force prediction markets to rethink their business models — either by getting licensed as sportsbooks or by dropping sports contracts entirely. Either way, the era of prediction markets operating without scrutiny is coming to an end. And for users, that means fewer options and more restrictions. But it also means clearer rules and better consumer protections. So if you're in Missouri and you've been using these platforms to bet on sports, you might want to start looking for alternatives. The clock is ticking. We'll keep you updated as this story develops. In the meantime, stay informed and know the rules in your state.
