Nevada has formally sued Kalshi after a federal appeals court refused to stop the state from moving ahead with enforcement action against the prediction-market operator.
The dispute escalated after the U.S. Court of Appeals for the Ninth Circuit denied Kalshi’s emergency request for a stay. The company had asked the court to temporarily block Nevada regulators from taking action while broader questions over federal and state authority were being litigated. With that request rejected, Nevada regulators moved swiftly to file a civil complaint in state court.
At issue are Kalshi’s event contracts tied to sports outcomes. Nevada regulators argue that contracts based on the results of professional and collegiate sporting events effectively amount to sports wagering under state law. Because Kalshi does not hold a Nevada gaming license, the state contends the company is offering unapproved gambling products to residents.
Nevada Seeks Injunction as Jurisdiction Fight Deepens
The lawsuit, filed by the Nevada Gaming Control Board, seeks injunctive relief to prevent Kalshi from continuing to operate in the state. Regulators argue that permitting the contracts to remain available threatens the integrity of Nevada’s tightly regulated gaming market and places licensed sportsbooks at a competitive disadvantage.
State officials maintain that Nevada law clearly defines wagering on sports outcomes as regulated gaming activity, regardless of how the contracts are structured. In their view, labeling the products as financial instruments does not exempt them from state oversight when they function similarly to traditional bets.
Kalshi Cites Federal Oversight Under CFTC
Kalshi, however, maintains that its contracts fall under exclusive federal jurisdiction. The company operates as a federally approved exchange overseen by the Commodity Futures Trading Commission (CFTC) and argues that the Commodity Exchange Act preempts state gaming laws in this context. According to Kalshi, once a contract is listed under federal commodities regulation, states cannot impose additional licensing requirements.
The clash reflects a broader national debate over how prediction markets should be classified. Several states have scrutinized similar offerings, raising questions about where the line between regulated derivatives and gambling should be drawn.
The outcome of Nevada’s case could carry significant implications for the prediction-market industry. A ruling in favor of the state would strengthen the authority of local gaming regulators to challenge federally approved event contracts. A decision favoring Kalshi, by contrast, could limit state intervention and reinforce federal primacy over such markets.
Not Just Kalshi: The Broader Fight Over Prediction Markets
Nevada’s action against Kalshi reflects a broader crackdown on prediction-market platforms. Other operators, including Polymarket and Coinbase, have faced state enforcement or court orders restricting their event contracts, as regulators argue these products resemble unlicensed sports wagering. The disputes show that Kalshi is not alone in navigating conflicts between state gaming laws and emerging digital financial markets.
The conflict is intensified by federal involvement. The CFTC has asserted exclusive authority over these markets, arguing that event contracts fall under federal derivatives regulation. This sets up a recurring clash between state regulators enforcing local gaming rules and federal authorities overseeing financial instruments, leaving multiple platforms caught in a complex and evolving legal landscape.
