Kalshi is caught in a legal battle that pits a state court against a federal agency. Michigan’s Attorney General has issued a restraining order against the prediction market platform, while the Commodity Futures Trading Commission (CFTC) has demanded that Kalshi continue its operations in the state. This intense clash may force the US Supreme Court to clarify whether prediction markets fall under federal or state jurisdiction.
A Clash of Orders
The conflict began when Michigan Attorney General Dana Nessel sued KalshiEx LLC in March 2026, accusing the company of violating the state’s Lawful Sports Betting Act by offering unlicensed sports event contracts to residents. The case bounced between courts until a state judge issued a temporary restraining order on June 29, barring Kalshi from marketing or providing sports-related contracts to Michigan users.
However, the CFTC intervened just weeks later with a direct order instructing Kalshi to persist in servicing Michigan traders. The federal regulator views Kalshi’s contracts as derivatives under its authority, contrasting sharply with Michigan’s classification of them as illegal sports wagers. This contradiction creates a rare jurisdictional dispute over who truly regulates these markets.
The Preemption Question
The core legal issue revolves around federal preemption: does the CFTC’s power over derivatives trump state gambling laws in regulating prediction markets? Kalshi operates under CFTC designation as a contract market, treating event contracts as financial instruments rather than bets. Michigan insists these products fall under its gambling prohibitions without proper licensing.
The CFTC’s assertive stance, ordering Kalshi to disregard the state injunction, highlights the agency’s determination to claim exclusive oversight. This battle is part of a broader pattern; in late 2025, cryptocurrency exchange Coinbase also challenged multiple states, including Michigan, over similar jurisdiction questions, and Polymarket is involved in parallel suits. These cases collectively signal a nationwide debate shaping the future governance of digital prediction markets.
Implications for Market Participants
If the Supreme Court sides with federal preemption, Kalshi and similar platforms could operate smoothly across states under a unified CFTC framework. This would reduce regulatory hurdles and licensing costs, potentially boosting market growth and innovation. Conversely, a ruling favoring state authority could fragment the market, forcing platforms to comply with a patchwork of state gambling laws much like existing sportsbooks.
The dispute also shows the growing prominence of digital asset derivatives and the CFTC’s efforts to solidify its jurisdiction. Since 2025, Kalshi has enjoyed the CFTC’s recognition as a designated contract market, legitimizing its sports contracts in many regions but leaving states like Michigan at odds with that designation.
