Tennessee authorities have issued an enforcement order requiring prediction market platforms Polymarket and Kalshi to cease all sports betting contract operations within the state. The directive mandates that both firms immediately halt Tennessee-based activities, process full refunds of customer deposits, and terminate all open contracts by January 31st. This regulatory action reflects growing scrutiny of decentralized prediction markets in the US, particularly around sports wagering compliance. The order underscores the tension between on-chain betting protocols and state-level gaming regulations. Market participants in affected jurisdictions should review position exposure and anticipated refund timelines. The move signals intensifying enforcement efforts targeting crypto-native betting platforms, potentially prompting similar actions across other states with restrictive gaming statutes.
