Tennessee Judge Pauses State Case Against Prediction Market Kalshi

A federal judge in Tennessee has temporarily blocked state regulators from taking enforcement action against Kalshi.

In an order issued Monday, US District Judge Aleta Trauger granted Kalshi’s request for a preliminary injunction and temporary restraining order against the Tennessee Sports Wagering Council and the state’s attorney general.

The ruling prevents regulators from enforcing a recent cease-and-desist order while the case proceeds.

Judge Says Tennessee Action Would Cause Irreparable Harm to Kalshi

Judge Trauger said Kalshi would face “irreparable injury and loss” if the state’s actions were allowed to continue and found that the company is likely to succeed on the merits of its claims.

She added that Kalshi’s rights would likely be violated absent court intervention.

The dispute began Friday, when the Tennessee Sports Wagering Council sent cease-and-desist letters to Kalshi, Polymarket and Crypto.com, ordering them to halt the offering of sports event contracts in the state.

Regulators accused the platforms of providing unlicensed sports wagering products and directed them to void existing contracts and refund Tennessee users by Jan. 31.

The letters warned of civil penalties of up to $25,000 per violation.

Kalshi moved quickly to challenge the order in court, suing the council, its leadership and the state attorney general.

The company argued that Tennessee overstepped its authority by attempting to regulate a federally overseen derivatives exchange.

Kalshi contends that it operates under the exclusive jurisdiction of the Commodity Futures Trading Commission, which oversees designated contract markets.

According to the company, state-level intervention conflicts with the federal regulatory framework established by Congress for derivatives trading.

“Tennessee’s intent to regulate Kalshi intrudes upon the federal system for overseeing derivatives markets,” the company said in its complaint, framing the case as a clash between state gambling laws and federal commodities regulation.

The Tennessee lawsuit mirrors similar legal battles unfolding across the US. Kalshi has filed suits against other state regulators that have attempted to restrict prediction markets, with mixed results.

Courts in Nevada and New Jersey have granted temporary relief, blocking state action while litigation continues, while a federal judge in Maryland declined to issue a similar injunction.

State Opposition to Prediction Markets Builds Over Consumer Concerns

State opposition to prediction markets has been building for months.

In 2025, the SWC urged the CFTC to prohibit sports event contracts, arguing that such products bypass state safeguards such as age verification, responsible gaming rules and anti-money laundering requirements.

As reported, a new legislation to limit the interactions between government officials and the prediction markets is being supported by more than 30 Democrats in the US House of Representatives, including former Speaker Nancy Pelosi.

The lure behind new restrictions is a controversial Polymarket bet, which started as a bet of $32,000 but eventually became more than $400,000 shortly before the unexpected detention of Venezuelan President Nicolás Maduro.

The bill proposed by the New York Representative Ritchie Torres is the Public Integrity in Financial Prediction Markets Act of 2026.
