Missouri attorney general orders suspension of sports betting prediction markets, sending letters to Polymarket, Kalshi, Crypto.com, Novig, Underdog and Robinhood

Missouri’s attorney general has told several prediction-market operators to suspend sports betting-related activity in the state. For high-risk payment teams, the useful bit is simple: when a regulator starts naming platforms one by one, the question stops being abstract and becomes a concrete exposure check.

1. The attorney general’s office sent letters to Polymarket, Kalshi, Crypto.com, Novig, Underdog and Robinhood, ordering them to pause their sports betting prediction-market operations in Missouri.
2. The source does not give the text of the letters or a further explanation from the office, so the only confirmed fact here is the directive itself and the list of companies that received it.
3. For PSPs, acquirers and banking partners, the signal is straightforward: products that look like prediction markets can be treated as sports-betting exposure at state level, even before any broader market narrative gets built around them.
