Prediction markets: Will Supreme Court or Congress settle the issue?

Summary

Tribal leaders, states and industry lawyers are locked in a rising legal battle over sports prediction markets run by firms such as Kalshi and Polymarket. States and tribes argue these operators are effectively offering gambling and must be licensed at state level, while prediction‑market firms say the Commodity Futures Trading Commission (CFTC) supervises their contracts under the Commodities Exchange Act (CEA). Recent federal rulings — especially a Maryland decision that criticised Kalshi’s arguments — have spurred a wave of lawsuits across numerous states. Key issues include whether contracts are ‘swaps’ under federal law, the feasibility of geofencing, the CFTC’s potential role, and whether the dispute will ultimately be resolved by the courts or by Congress.

Key Points

Lawsuits are multiplying: Nevada, Illinois, Massachusetts, Tennessee, Arizona, Connecticut, Maryland, New Jersey, Ohio, Montana and others are taking action against prediction markets.
Maryland’s federal court decision in August was pivotal — it declined Kalshi’s preliminary injunction and questioned Kalshi’s legal consistency, triggering more state suits.
States and tribes contend prediction markets cannot evade state regulation by claiming CFTC authority under the CEA; at least one judge said that interpretation would upend decades of federalism in gaming regulation.
Geofencing, once argued to be impractical by operators, is now being deployed by firms (and newcomers like FanDuel/DraftKings), weakening operators’ legal claims about technical impossibility.
The CFTC has so far stayed mostly out of the fights but could change stance; CFTC Chair Michael Selig has been sympathetic to sports event contracts and might propose rules or approval frameworks.
Possible endgames: continued litigation through 2027, a U.S. Supreme Court decision (potentially 2028), or Congressional action amending the CEA or creating a federal sports‑betting regime; states alone have limited leverage short of federal clarification.

Context and relevance

This dispute sits at the intersection of gaming regulation, federalism and fintech innovation. For tribal operators, state regulators and commercial bookmakers, the outcome will reshape who controls licensing, revenue and integrity controls for prediction markets that settle on sports outcomes. The case tests whether derivative‑market law can be stretched to cover sports betting — a move that would centralise authority with federal regulators and significantly alter the US gambling landscape.
