NFL Asks Supreme Court Who Regulates Prediction Markets

The NFL asked the Supreme Court on Thursday to hear a fight over who gets to regulate sports prediction contracts. Its preferred answer is the states. Kalshi, the company at the center of the New Jersey case, argues that its contracts fall under federal commodities oversight.

That sounds like a dispute for lawyers until you ask what changes for a customer opening an app. State-regulated sports betting commonly sets the minimum age at 21. Kalshi permits customers as young as 18 to trade. The NFL also wants restrictions on contracts it considers vulnerable to manipulation or inside information. The court has been asked to review the case; it has not settled those questions.

The league has a second decision to make while the legal one plays out: whether to work commercially with the companies listing contracts on its games. MLB and the NHL have chosen partnerships. The NFL has held back. That makes this a test of two ways to shape a growing market: seek rules from outside a deal, or build a relationship with the firms already operating it.

How Football Reached the Supreme Court

New Jersey asked the justices to review a ruling in its dispute with Kalshi. The Third Circuit treated Kalshi’s sports event contracts as federally regulated swaps, shielding them from state gambling laws. The Sixth and Ninth Circuits have taken a different approach to whether federal oversight displaces state authority. The NFL filed a supporting brief on Thursday, urging the Supreme Court to take the case and favor the state-regulation side of that split.

The underlying question is who writes and enforces the rules when someone trades a contract tied to a football outcome. If federal commodities law gives the Commodity Futures Trading Commission, or CFTC, exclusive authority over these contracts, a state cannot simply apply its sports-betting rules to them. If states retain that authority, operators face the gambling laws that govern sportsbooks where they operate. The legal outcome would therefore affect the rules customers encounter, as well as which regulator the league approaches when it wants a contract restricted.

New Jersey has company in seeking an answer. Attorneys general for 39 states and the District of Columbia, along with a coalition of 145 tribal nations and organizations, filed briefs supporting its request. Their participation shows how far the jurisdiction question extends beyond one league’s preferences: state and tribal gambling authorities also have an interest in whether federally regulated exchanges can operate outside their betting frameworks.

The NFL did not discover this concern on filing day. It has objected for more than a year to contracts involving player injuries and weather delays, and to the gap between an 18-year-old trading minimum and the 21-year-old standard at most state-regulated sportsbooks. The CFTC is working on prediction-market rules but has not finalized rules specific to them.

That history explains the trip to court. The NFL had already been arguing about contract design and safeguards with the industry. Conflicting appeals-court rulings now put a more basic issue in play: whether states can require the protections the league wants. The league’s brief gives the justices its preferred answer, though the justices must first decide whether to take the case at all.

The Contracts Behind the Jurisdiction Fight

The NFL’s objections get concrete fast. It worries about contracts tied to injuries or officiating, where someone close to a team or game might know the answer early. It also points to outcomes a participant could influence. A deliberately missed field goal is an example the league has raised. These are the league’s concerns about possible abuses, not findings that a player has manipulated one of these markets.

Its filing questions whether the CFTC has the resources to oversee the industry and argues that the agency’s proposed rules fall short on integrity and consumer protection. The NFL says traditional state-regulated betting has stronger safeguards.

The companies and regulator dispute the diagnosis. Kalshi says the CFTC already polices sports-related markets and that its ongoing rulemaking addresses many of the league’s concerns. Polymarket says its surveillance tools and work with federal regulators can support a consistent national approach, rather than a collection of state systems. The agency had engaged with the NFL and the league declined a memorandum of understanding that could have helped the two exchange information, a CFTC spokesperson said.

That response identifies an option short of a commercial partnership: the NFL could cooperate with the federal regulator while still declining to promote an operator. The league’s position leaves room for a federal outcome, too. In its brief, it says that if the Supreme Court concludes the CFTC has exclusive authority, it could press the agency, exchanges and Congress for stronger protections before the 2027 season. The league wants safeguards even if its preferred regulator loses the argument.

MLB and the NHL Chose Another Door

MLB named Polymarket its exclusive prediction-market sponsor in March and signed an integrity agreement with the CFTC. The NHL has partnerships with Kalshi and Polymarket and has licensed its trademarks to prediction markets. The NFL has signed no comparable partnership and maintains an advertising ban on prediction platforms. In a September 10 CNBC Sport interview, commissioner Roger Goodell said the league wanted stronger protections before considering a tie-up.

Those choices give each league a different route into the same market. A sponsorship or trademark license creates a commercial relationship with an operator. An integrity agreement creates a channel for cooperation with a regulator. The NFL, without a commercial deal, is asking the courts to preserve a state-led framework it considers more protective. It has also talked with prediction-market firms and the CFTC, so sitting out a partnership does not mean sitting out the conversation.

The comparison has a hard limit: a deal tells us who is working together, not whether that arrangement catches more suspicious trading or produces a better return for a league. MLB’s sponsorship and CFTC agreement also do different jobs. One concerns commercial association; the other concerns communication about integrity. Treating them as a single vote of confidence in every contract an operator lists would give the partnership more meaning than its terms support.

The scale helps explain why leagues are making these choices now. The NFL’s brief says contracts related to its games accounted for $1.8 billion of $3.3 billion in prediction-market trading volume on the season’s first Sunday. That is one day’s reported trading, not NFL revenue, operator profit or a forecast of what a sponsorship would pay.

For a league, the calculation is about more than whether fans trade on its games. Fans already do. The question is whether the league gets the safeguards it wants through state gambling regulators, through federal rulemaking and information-sharing, or through relationships with operators. The Supreme Court may choose whether to hear the jurisdiction fight. Meanwhile, MLB and the NHL are building relationships inside a market whose rulebook is still contested.
