Kalshi loses fourth circuit appeal as state sports bet jurisdiction widens
Shayne Coplan built Kalshi on a single legal premise: that federal commodity law, specifically the CFTC's exclusive jurisdiction over swaps, sits above anything a state gaming board can do. Four federal circuits have now looked at that premise in the context of sports contracts, and four have disagreed.
The latest ruling, against Kalshi's sports prediction contracts, is not simply another loss in a losing streak. It is the point at which a legal theory stops being contested and starts being settled. I have watched regulatory disputes run through the courts long enough to know the difference between a circuit split that invites Supreme Court resolution and a consolidating consensus that makes review less likely, not more. This is starting to look like the second thing.
The mechanism matters. Kalshi's argument was always that a sports event contract, properly structured, is a commodity future — a financial instrument whose regulation belongs exclusively to Washington. States said: call it what you like, someone is wagering on a game, and that is ours. Four circuits have found enough merit in the state position to let those regulations stand. The CFTC's silence on a clean definitional rule, which the newsroom has noted before, has done Kalshi no favours. When the federal regulator has not drawn its own line, courts have less reason to assume federal law occupies the ground.
What I think the reporting undersells is the commercial consequence. Kalshi's sports vertical was not a sideline — it was the most legible product for mass-market acquisition, the thing that makes prediction markets comprehensible to someone who doesn't already trade volatility. Lose that product in enough jurisdictions and you are left with a platform that appeals to the same audience it already has. Growth requires something simpler than an interest rate market, and sports contracts were that product.
The Polymarket situation adds a different layer. New York's lawsuit against Polymarket, Governor Hochul and Attorney General James both attached, has a different legal texture than the Kalshi circuit cases — it runs through state gambling law rather than federal preemption doctrine. But the direction is the same. Two of the sector's largest operators are simultaneously in court with state regulators, and the states are accumulating wins.
I have been watching the prediction market regulatory trajectory since before most people in this sector were paying attention to it, and I got parts of it wrong. My view in 2024 was that federal preemption would hold longer than it has, that the CFTC's jurisdictional claim over event contracts would prove stickier in court. The circuit losses have moved me. The thesis I would defend now is that the federal preemption play is effectively over for sports contracts specifically, and that what comes next is either federal legislation that explicitly extends CFTC reach — which requires a Congress that has not shown appetite for it — or a product redesign that abandons the sports vertical entirely in favour of contracts that look less like bets on games.
Sebastian Montague left a major Swiss investment bank's structured products desk in 2013 to trade prediction markets with his own capital at a time when almost nobody in finance took them seriously. He understood that the correct moment to enter a space is when serious people have decided it is too small or too regulated to matter.

Kalshi argued that sports event contracts, structured as commodity futures under federal law, fall exclusively under CFTC jurisdiction and preempt state gaming regulations. Four federal circuits have rejected this premise, ruling that state gaming boards retain authority over wagering on sports events regardless of how the contracts are structured financially. The CFTC's failure to issue a clear definitional rule distinguishing sports contracts from gambling has left courts reluctant to assume federal law occupies the regulatory ground.
The Fourth Circuit decision represents the fourth consecutive federal circuit to reject Kalshi's legal theory that commodity law preempts state sports gambling regulation. This consolidating consensus across multiple circuits—rather than a split inviting Supreme Court review—signals that the federal preemption framework for sports contracts is settling into established precedent, making further appellate challenge less likely to succeed.
Kalshi's sports prediction contracts were its primary product for mass-market customer acquisition, making prediction markets comprehensible to mainstream users unfamiliar with volatility trading. Loss of that product across enough jurisdictions forces the platform toward existing users in niche markets like interest rate derivatives, eliminating the simpler on-ramp necessary for growth and limiting expansion beyond its current audience.
Two major prediction market operators—Kalshi and Polymarket—face simultaneous state court actions, with states accumulating regulatory wins through both federal preemption challenges and state gambling law enforcement. The consistent pattern across four circuits rejecting federal preemption, combined with active state litigation, signals that future industry expansion depends on federal legislation explicitly extending CFTC authority rather than relying on judicial recognition of existing federal jurisdiction.
