A federal judge has ruled that Utah can enforce its anti-gambling laws against prediction market platforms such as Kalshi and Polymarket, marking a notable development in ongoing legal disputes over the regulation of these emerging betting markets. The decision came on Tuesday in U.S. District Court in Salt Lake City.
Utah has taken a firm stance on restricting prediction markets, which allow users to place bets on the likelihood of various events, including proposition bets on specific occurrences within sports games rather than overall outcomes. Such wagers represent a significant portion of revenue for companies like Kalshi.
Kalshi filed a lawsuit against Utah in February, seeking to prevent the state from applying its gambling restrictions to the platform. The company argued that federal law preempts state regulations in this arena, asserting that prediction markets are governed under federal jurisdiction and not subject to a broad array of state gambling statutes. The legal effort coincided with Utah’s move toward legislation designed to limit the operations of these markets within its borders.
U.S. District Judge Robert Shelby denied Kalshi’s request for an injunction, finding that federal law cited by Kalshi does not prohibit Utah from enforcing its gambling laws. Despite the ruling, residents of Utah can still access prediction markets for now, as enforcement measures are still being finalized.
Utah Attorney General Derek Brown emphasized the state’s intent to uphold its laws, stating, “Gambling is gambling, no matter what any company calls it,” though he acknowledged that enforcement strategies are still being considered.
Kalshi responded to the ruling by announcing plans to appeal the decision, maintaining its position that federal oversight should apply exclusively to prediction markets and warning against a fragmented regulatory environment driven by varied state regulations.
This case reflects a broader national debate over the regulation of prediction markets, which straddle lines between finance and gambling laws. Courts across several states have delivered mixed rulings: judges in Maryland, Nevada, Ohio, New York, and Wisconsin have sided against Kalshi, upholding state restrictions, while courts in New Jersey, Tennessee, Arizona, and Minnesota have ruled in favor of the platform. Other jurisdictions have permitted limited state restrictions without issuing outright bans.
As prediction markets continue to grow in popularity, the legal landscape remains unsettled, with tension persisting between efforts to regulate gambling and claims for federal oversight of these novel financial platforms.
