U.S. regulators asked a federal court to stop Arizona from enforcing gambling laws against Kalshi. They said sports event contracts qualify as federally regulated swaps. The filing sets a direct dispute over whether those products are bets or financial derivatives.
CFTC Says Contract Structure Controls Federal Treatment
The Commodity Futures Trading Commission and the Department of Justice filed their argument late Tuesday. They urged the court to block Arizona from applying state betting laws to Kalshi.
The agencies said the contracts depend on future events and fit the legal definition of swaps. They argued that federal law governs those products, even when they track sports or elections.
The filing said the Commodity Exchange Act gives the CFTC “exclusive jurisdiction” over swaps. Therefore, the agencies said Arizona cannot treat those contracts as illegal gambling.
Federal lawyers argued that contract structure matters more than the subject of the contract. They said economic consequences can arise from many future events, including sports outcomes.
The government also warned against a patchwork system across multiple states. It said Congress intended one national framework for federally regulated derivatives markets.
Arizona Case Tests State Power Over Sports Contracts
Arizona has taken a harder line than several other states in this dispute. State authorities filed criminal charges against Kalshi under Arizona betting laws.
Arizona argues that sports outcome contracts work like traditional wagers placed through sportsbooks. Therefore, the state says those products should follow licensing, age, and consumer protection rules.
The dispute has grown as more states challenge sports contracts on prediction platforms. However, Arizona moved further by bringing criminal charges instead of civil enforcement alone.
Kalshi has argued that federal law allows its exchange to list these contracts. The company says states cannot override federal oversight of approved event contracts.
Recent court decisions have not moved in one direction. A federal appeals court in New Jersey recently sided with Kalshi on sports contracts.
That court found the contracts are presumptively lawful under federal law unless the CFTC acts. Other courts, however, have allowed state enforcement efforts to continue.
The federal filing said state prosecutions could disrupt a national market Congress placed under federal supervision. It compared sports contracts to derivatives tied to oil prices or interest rates.
The government asked the court to focus on legal classification, not public perception. It said a contract does not become gambling simply because sports fans recognize the event.
Courts now must decide whether Arizona can enforce state gambling laws against Kalshi. The case includes criminal charges, and an arraignment is scheduled for April 13.
The filing marked the clearest federal statement in support of Kalshi’s position. It also restated the CFTC view that sports event contracts can fall under federal derivatives law.
