The Sixth Circuit just told Kalshi the quiet part out loud: a sports contract that looks like a bet, prices like a bet, and pays like a bet is a bet, and states get to treat it that way.
On September 25, 2026, a unanimous three-judge panel of Circuit Judges Eric L. Clay, Julia Smith Gibbons, and Rachel S. Bloomekatz crushed Kalshi’s bid to lock Ohio and Tennessee out of regulating its sports-event contracts. Gibbons wrote the opinion. The court affirmed the Southern District of Ohio’s denial of a preliminary injunction, vacated the Middle District of Tennessee’s grant of one, and sent the Tennessee case back down. Kalshi argued these products sit inside the Commodity Futures Trading Commission’s exclusive lane as “swaps” under the Commodity Exchange Act. The panel said Kalshi never cleared that bar.
I am not soft-pedaling this. Prediction-market users spent months selling the idea that Kalshi was a cleaner, federally armored alternative to licensed books. The Sixth Circuit looked at the product and refused the costume.
Corner Kicks Are Not Interest Rates
Gibbons put the legal hammer where it belongs. “We hold that Kalshi has not shown that its sports-event contracts satisfy the statutory definition of a ‘swap’ so as to fall within the scope of the CFTC’s ‘exclusive jurisdiction.’” Even if you grant the swap label for argument’s sake, the CEA still does not expressly or impliedly preempt Ohio’s or Tennessee’s gambling and sports-wagering laws. That is the whole case in two sentences.
The opinion then goes straight at the product itself. “Unlike contracts based on financial values or instruments (e.g., interest rates or stock prices), Kalshi’s sports-event contracts have only downstream economic consequences, assuming they have the potential to cause economic consequences at all.” And the line that should end every Twitter thread pretending this is sophisticated market infrastructure: “It is, therefore, difficult to see how determining the probability that a certain number of corner kicks will be taken in a given soccer game — or that a 30-leg parlay will hit — would serve (to) advance those goals.”
That is the record. Kalshi’s reading, the court said, “would give the CFTC jurisdiction over event contracts that bear no relation to the goals Congress had in mind.” Sports outcomes are not intrinsically tied to financial risk the way rates or equities are. Downstream side effects do not magically convert a prop into a swap. The panel also noted that state gambling laws “impose no restrictions on the designation or operation of contract markets as such. Instead, they regulate sports betting.” The pressure hits DCMs only because platforms like Kalshi chose to list contracts “virtually indistinguishable from” sports bets.
I read that and see a platform that tried to route around state licensing, taxes, and consumer rules by waving a CFTC designation. Tennessee Attorney General Jonathan Skrmetti framed it as an end run around state law and the rules and taxes that come with sports gambling. The Sixth Circuit just gave that framing judicial force.
The Split Is Now a Supreme Court Problem
This is not an isolated skirmish. The Sixth Circuit joins the Ninth Circuit’s August 28, 2026 Nevada ruling against Kalshi. The Third Circuit went the other way on New Jersey in April 2026, and New Jersey has already petitioned the Supreme Court. Roughly twenty states are in active litigation. The CFTC has sued nine states. Forty-four states signed a July letter arguing the CFTC lacks authority over sports-related event contracts. Ohio’s Casino Control Commission had already moved toward a multimillion-dollar fine earlier in the fight.
Kalshi can say it expects the ruling not to survive further review. That is what every losing side says on day one. The legal reality on the ground right now is simpler: in the Sixth Circuit, sports-event contracts on a DCM do not automatically sit above state gambling enforcement. Bettors treating Kalshi as a frictionless national picks venue just lost that shield in Ohio and Tennessee, with more states watching the same playbook.
For anyone grinding sides, totals, and props, the practical stake is access and durability. Licensed sportsbooks operate under state regimes for a reason: taxes, integrity monitors, age gates, responsible-gaming rules, and the political bargain that lets the product exist at all. A platform that offers the same economic exposure without that bargain is asking courts to invent a federal escape hatch Congress never wrote. Gibbons refused to invent it.
I am planting the flag here. The Sixth Circuit got the classification right. A 30-leg parlay priced on a CFTC market is still a 30-leg parlay. States that built sports-wagering frameworks after PASPA did not surrender them the minute a DCM listed the same games. The Supreme Court will almost certainly have to clean up the circuit split. Until it does, every sharp who treated Kalshi sports contracts as permanently federally armored product is pricing a risk the Sixth Circuit just made real.
The contracts keep trading until someone shuts the spigot. The legal armor just took a direct hit, and the next court that cares about corner kicks versus interest rates already has the template.
