States Crack Down on Crypto Prediction Market Betting

The ruling is the strongest judicial action yet in a widening conflict between US states and crypto-powered prediction markets over whether their sports contracts amount to illegal gambling.

What This Means for Crypto Casino Players

The crackdown on prediction markets like Kalshi, Polymarket, and Crypto.com signals a tightening regulatory environment for crypto-based betting across the United States. While prediction markets operate differently from traditional crypto sportsbooks, the legal precedent now being established could reshape how regulators view all forms of crypto wagering going forward. If courts broadly rule that crypto-based sports contracts are gambling, it may invite additional scrutiny of the wider crypto betting ecosystem.

Players who use cryptocurrency for sports betting should pay close attention to which platforms hold proper licensing. Regulated crypto sportsbooks that accept Bitcoin, Ethereum, and other digital currencies continue to operate and serve US players through established international licences.

39 State Attorneys General Back the Crackdown

The Massachusetts injunction is part of a far larger regulatory push. A bipartisan group of 39 state attorneys general and the District of Columbia recently urged a federal court to uphold state authority over sports gambling regulation, directly challenging the Commodity Futures Trading Commission's claim of exclusive jurisdiction over prediction market contracts.

Officials in at least 11 states have now sent cease-and-desist orders to prediction market operators. Tennessee ordered Kalshi, Polymarket, and Crypto.com to stop offering sports-related contracts, void all existing positions, and issue full refunds to users. Nevada's Gaming Control Board has also taken enforcement action, and Massachusetts became the first state to secure a court injunction requiring Kalshi to geoblock its residents entirely from sports contracts.

The central legal question driving these cases is whether sports contracts on platforms like Kalshi are financial instruments regulated by the CFTC, or sports wagers subject to state gambling laws. Federal courts have reached conflicting conclusions, with rulings in Tennessee favouring Kalshi's position while the Massachusetts court rejected it.

What to Watch

Legal analysts widely expect the jurisdictional dispute between federal and state regulators to reach the Supreme Court. Kalshi currently faces roughly 20 active lawsuits across multiple states. In response, the prediction market industry has launched the Coalition for Prediction Markets — a lobbying group that includes Crypto.com, Coinbase, Kalshi, and Robinhood — to advocate for a unified federal regulatory framework. For anyone using cryptocurrency to place bets, the regulatory ground is shifting quickly.
