NFL Asks Supreme Court to Classify Kalshi Sports Contracts as Gambling

The NFL Steps Into a Federal Courtroom Fight

The National Football League has entered one of the more consequential legal battles over prediction markets, filing an amicus brief urging the Supreme Court to take up New Jersey’s challenge against Kalshi. At the center of the dispute is a deceptively simple question: are sports event contracts financial instruments regulated by the Commodity Futures Trading Commission, or are they gambling products that states have the authority to ban?

The NFL’s answer is unambiguous. The league argues that what Kalshi sells – contracts tied to the outcomes of sporting events – are gambling products, full stop, and that dressing them in the language of derivatives does not change what they fundamentally are. That position, coming from one of the most commercially powerful sports organizations in the United States, adds significant institutional weight to New Jersey’s push for Supreme Court review.

How Kalshi Got Here

Kalshi operates as a CFTC-regulated prediction market, which means its contracts are technically classified as commodity futures rather than gambling products. The company won CFTC approval to list event contracts, including those tied to sports outcomes, after a regulatory battle that stretched across multiple years. That approval was the foundation of its legal argument: if the federal regulator has blessed these products, states cannot step in and prohibit them under their own gambling laws.

New Jersey disagreed. The state moved to block Kalshi from operating within its borders, arguing that federal commodity law does not preempt state gambling statutes when the underlying contract is, in substance, a bet on a sporting event. Lower courts sided with Kalshi, which is precisely why New Jersey is now asking the Supreme Court to weigh in – and why the NFL felt the moment warranted a formal filing.

The NFL’s amicus brief does not simply ask the court to rule against Kalshi on the merits. It asks the court to hear the case at all – a threshold question that matters because the Supreme Court takes a small fraction of the petitions it receives. By filing at the certiorari stage, the NFL is signaling that it views the question as sufficiently important to national policy that the court cannot responsibly leave the lower court ruling standing without further scrutiny.

What the CFTC Classification Actually Means

The regulatory classification at issue carries real consequences. Under the Commodity Exchange Act, CFTC-regulated contracts enjoy a form of federal preemption that can override state law. If sports event contracts qualify as legitimate swaps or futures, states lose much of their ability to prohibit them, regardless of how those states have historically treated sports wagering. That preemption argument is the legal engine behind Kalshi’s position, and it is exactly what the NFL and New Jersey are trying to dismantle.

The CFTC’s willingness to approve sports event contracts represents a significant jurisdictional expansion for the agency, one that the NFL clearly views as an overreach into territory that has traditionally belonged to state gambling regulators – and, more recently, to the sports leagues themselves through negotiated commercial arrangements with licensed sportsbooks. The financial stakes for the league are not abstract: if prediction market contracts proliferate outside the existing sports betting framework, the NFL’s carefully structured licensing relationships with operators like DraftKings and FanDuel face an entirely different kind of competition, one that sidesteps the state-regulated channels those partnerships depend on.

A Jurisdictional Fault Line With Broader Implications

The case sits at the intersection of three regulatory frameworks that rarely interact this directly: federal commodities law, state gambling statutes, and the emerging prediction market industry. Kalshi is not the only company with exposure to the outcome. Other prediction market platforms that have pursued or are considering CFTC-regulated sports contracts would face the same legal uncertainty if the Supreme Court takes the case and rules against the federal preemption argument.

For digital asset markets, the underlying jurisdictional question has a familiar shape. The boundary between what the CFTC regulates and what falls under other legal categories – state law, SEC jurisdiction, outright prohibition – has been contested terrain for years. The CFTC and SEC have both moved to assert rulemaking authority over digital assets as Congress has struggled to pass comprehensive legislation, and the Kalshi case adds another dimension to the question of how far federal commodity regulation can stretch before states push back successfully.

What makes the NFL’s involvement particularly sharp is the commercial logic behind it. The league has invested substantially in its relationships with state-licensed sportsbooks, relationships that depend on the regulated gambling framework remaining the dominant channel for sports wagering. A ruling that cements CFTC jurisdiction over sports event contracts would effectively carve out a parallel market – one that operates under federal commodity law and does not flow through the state-licensed systems the NFL has built its betting partnerships around.

The Supreme Court has not yet decided whether to grant certiorari. If it declines, the lower court ruling favoring Kalshi stands, and the CFTC’s authority to approve sports event contracts remains intact for now. If it agrees to hear the case, the resulting decision could redraw the regulatory map for prediction markets across the country – with the NFL, New Jersey, and Kalshi each watching a very different set of financial stakes hang in the balance. The next filing deadline is the kind of procedural detail that rarely makes headlines, but in this case, it may determine whether billions of dollars in sports wagering infrastructure get reorganized around a federal agency’s definition of what counts as a swap.
