Tennessee Bans Sweepstakes Casinos and Creates New Crime for Prediction Market Manipulation

Tennessee Gov. Bill Lee has signed two gambling-related bills into law that ban online sweepstakes casinos from operating in the state and establish a new criminal offense for anyone who manipulates prediction market contracts. The legislation, which takes effect in Tennessee, represents one of the most aggressive state-level responses to the rapid growth of both industries and puts significant new pressure on operators who have relied on the state as a key market.

The sweepstakes casino industry, which has grown substantially in states where traditional online casino gambling is not yet legal, operates through a promotional model under which players use virtual coins rather than real money to play casino-style games. A separate class of coins can typically be redeemed for cash prizes, a mechanism that regulators and lawmakers increasingly argue functions as real-money gambling in practice, even if not in legal form. Tennessee’s new ban closes that loophole entirely within the state.

Sweepstakes Casinos Losing Ground Nationally

Tennessee’s ban follows similar action by Iowa, which recently signed legislation expanding its regulator’s authority over sweepstakes casinos, stopping short of an outright ban but imposing new oversight requirements. The trend signals that the largely unregulated sweepstakes casino industry is entering a new and more hostile regulatory environment, as more states move to either prohibit or formally regulate these platforms.

For residents of Tennessee who currently use sweepstakes casino platforms, the new law means those services are no longer legally available. Operators who continue to serve Tennessee residents following the ban’s effective date would be in violation of state law. The full scope of enforcement mechanisms and the effective date specifics are expected to be clarified through the state’s regulatory process.

Prediction Market Rules Tightened

Alongside the sweepstakes ban, the second bill signed by Gov. Lee creates criminal liability for individuals who attempt to manipulate or artificially influence the outcome of a prediction market contract. The legislation is specifically targeted at the sports event contracts offered by platforms like Kalshi and Polymarket, which have faced increasing legal challenges from states that argue the contracts are functionally equivalent to sports betting.

The Tennessee prediction market bill adds criminal consequences to conduct that federal regulators have largely addressed through the CFTC’s oversight framework. At the same time, a Rhode Island lawsuit against Kalshi and Polymarket is advancing in the courts, and a Senate hearing has put additional pressure on the industry to demonstrate that its products are meaningfully different from regulated sports betting.

Industry Implications

Both pieces of legislation reflect a broader shift in how state governments are responding to the expanding boundaries of online gambling. The sweepstakes casino model and the prediction market space have each grown rapidly by exploiting gaps between state gambling laws and federal oversight frameworks. As those gaps begin to close through state legislation, operators are being forced to choose between compliance, market exit, or legal challenge.

For bettors and players in Tennessee, the practical effect is significant. The state has made clear it will not allow either sweepstakes casinos or manipulation of prediction market contracts to operate without consequences. Players who relied on sweepstakes platforms as an alternative to licensed online casinos, which are not yet available in Tennessee, will need to find other options. Those who have been active in prediction markets for sports event contracts should also be aware of the new criminal statute.
