A federal judge has temporarily blocked Tennessee regulators from enforcing state gambling laws against Kalshi, marking an early procedural win for the federally regulated prediction market operator in a widening jurisdictional dispute.
The order, issued on 12 January by US District Judge Aleta Trauger, restrains the Tennessee Sports Wagering Council and state officials from applying Tennessee gambling statutes to Kalshi pending further court review.
The court found that Kalshi is likely to succeed on the merits of its claims against the state, concluding that enforcement of Tennessee law could violate rights preempted by federal authority.
Judge Trauger also determined that Kalshi would face irreparable harm absent relief and that the balance of equities favoured restraint.
A preliminary injunction hearing is scheduled for 26 January, with Kalshi required to post a $500 security bond before the temporary order remains in effect.
The ruling does not resolve the underlying dispute but preserves the status quo while the court considers whether state regulators can regulate federally approved event-based contracts.
The case centres on Kalshi’s position as a derivatives exchange overseen by the Commodity Futures Trading Commission, and whether its sports-related event contracts constitute gambling under Tennessee law.
State officials have argued that such contracts fall within prohibited sports wagering activity when offered to Tennessee residents.
Kalshi continues to argue that its products are federally authorised financial instruments and therefore insulated from state-level gambling enforcement.
Tennessee moves to block prediction markets
This dispute follows regulatory action by Tennessee authorities against multiple prediction market platforms from last week.
The Tennessee Sports Wagering Council previously ordered Kalshi, Polymarket, and Crypto.com to cease offering sports event contracts to residents of the state, citing unlicensed gambling activity.
Regulators directed the firms to shut down Tennessee-based access, refund customer deposits, and void open contracts by 31 January.
Noncompliance, officials warned, could trigger civil penalties of as much as $25,000 per violation and potential criminal referrals for the illegal promotion of gambling.
Those enforcement actions continue a broader tension between state gambling frameworks and emerging federally regulated prediction markets.
While firms such as Kalshi operate under CFTC oversight, state regulators maintain that the economic substance of sports event contracts mirrors traditional sports betting.
The key legal question remains whether federal commodities law preempts state gambling statutes when the underlying contracts reference sporting outcomes.
Polymarket and Crypto.com have not publicly disclosed whether they will pursue similar legal remedies in Tennessee.
The outcome of Kalshi’s case could nonetheless influence how other states approach enforcement against prediction markets.
