Tennessee Regulator Issues Cease-and-Desist to Polymarket Weeks After U.S. Relaunch

By dAppConNewcomer20 rep· 1/11/2026

Tennessee's sports betting regulator has issued cease-and-desist letters to prediction market platforms Polymarket, Kalshi, and Crypto.com's North American Derivatives Exchange. The order demands an immediate halt to offering sports event contracts to Tennessee customers, voiding pending contracts, and refunding all deposits by January 31, 2026. This marks the first state-level enforcement action against Polymarket since its recent re-entry into the U.S. market.

 

Key Takeaways

  • Tennessee's Sports Wagering Council (SWC) has ordered Polymarket, Kalshi, and Crypto.com's NDBX to cease offering sports event contracts to Tennessee residents.

  • All three platforms are federally registered with the CFTC, which they argue preempts state gambling regulations.

  • Tennessee cites consumer protection concerns and potential threats to state-regulated sportsbooks and tax revenue.

  • Non-compliance could lead to significant fines and referral to law enforcement for criminal charges.

  • Polymarket recently relaunched in the U.S. after acquiring QCX.

 

Regulatory Clash Over Event Contracts

The Tennessee Sports Wagering Council (SWC) sent letters dated January 9 to Polymarket, Kalshi, and Crypto.com's North American Derivatives Exchange (NDBX). The letters explicitly state that the sports event contracts offered on these platforms are not compliant with Tennessee's consumer protection laws and pose a significant threat to the public interest. SWC Executive Director Mary Beth Thomas emphasized that these offerings lack essential protections such as age restrictions, responsible gaming requirements, and anti-money laundering controls.

 

Federal Registration Versus State Authority

All three platforms are registered with the Commodity Futures Trading Commission (CFTC) as designated contract markets, a federal designation that permits them to offer event-based derivatives nationwide. They contend that this federal oversight should supersede state gambling regulations. However, this argument has faced mixed results in federal courts. Tennessee maintains that these contracts constitute illegal wagers under state law, regardless of federal registration.

 

Potential Penalties and Legal Ramifications

Tennessee's cease-and-desist letters outline a range of penalties for non-compliance. Under the Tennessee Sports Gaming Act, the SWC can impose fines starting at $10,000 for a first offense, escalating for subsequent violations. More critically, the letters reference Tennessee's criminal gambling statutes, which classify gambling promotion as a misdemeanor and aggravated gambling promotion as a felony. Failure to comply could result in a referral to law enforcement for further investigation.

 

Polymarket's Recent U.S. Return

Polymarket's re-entry into the U.S. market occurred following its acquisition of derivatives exchange and clearinghouse QCX for $112 million. The platform began opening its U.S. app to waitlisted users in December. The Tennessee action is the first publicly disclosed state-level cease-and-desist order targeting Polymarket since its U.S. relaunch, potentially impacting its expansion plans if other states adopt similar stances.

 

Industry Response and Future Outlook

While Polymarket and Crypto.com did not immediately respond to requests for comment, Kalshi stated that it has filed a lawsuit in federal court to block Tennessee's "unlawful attempt" to halt prediction markets. Kalshi argues that as a federally regulated exchange, it is subject to exclusive federal jurisdiction and is distinct from state-regulated sportsbooks. Legal experts anticipate further legal challenges, with platforms likely to contest state enforcement actions in federal court.
