NFL Amicus Brief Urges Supreme Court to Apply State Gambling Laws to Sports Prediction Contracts

Key Takeaways

• NFL Intervention: The league filed an amicus brief supporting New Jersey regulators against Kalshi, classifying sports prediction contracts as bets under state law rather than CFTC swaps.
• Volume Scale: NFL-related contracts generated $1.8 billion of the $3.3 billion in total prediction market trading volume on the first Sunday of the current season.
• Circuit Split: The Third Circuit sided with Kalshi in April while the Sixth and Ninth Circuits reached the opposite conclusion on federal authority.
• Integrity Demands: The NFL seeks prohibitions on manipulable bets, age-21 minimums, information-sharing mandates, and banned-participant lists.

The NFL has entered the dispute over sports prediction markets with an amicus brief filed in support of New Jersey regulators. The filing asks the U.S. Supreme Court to resolve whether these contracts qualify as state-regulated bets or as federal swaps overseen by the Commodity Futures Trading Commission.

The brief states that billions of dollars will be bet on NFL games through prediction markets each season. Any delay, it warns, will increase consumer harm and risk to game integrity.

NFL Position on Contract Classification

The NFL argues that sports prediction contracts create new risks for participants who choose to wager rather than hedge existing business exposures. Financial swaps, by contrast, allow firms to manage risks they already face. The league contends it is inconceivable that Congress, in response to the 2008 financial crisis, enabled nationwide legalization of sports bets dressed up as swaps.

This stance aligns with rulings from the Sixth and Ninth Circuits. Those courts rejected the Third Circuit’s April decision favoring Kalshi. The split creates immediate commercial uncertainty for operators and platforms active in this space.

As first reported by InGame, the NFL’s brief supports New Jersey’s petition for Supreme Court review. The league seeks a definitive ruling before another NFL season concludes.

Specific Protections Sought by the League

The NFL identifies multiple gaps in current federal oversight. It calls for bans on bets that one person can easily manipulate, wagers involving player injuries or officiating decisions, and propositions on outcomes knowable in advance. Examples include whether a kicker will miss a field goal or whether a team’s first play will be a run or a pass.

A minimum age of 21 is required. Operators must maintain and share lists of banned individuals, including league employees and medical staff with access to nonpublic information. The brief acknowledges federal insider-trading rules and Kalshi’s partnership with Integrity Compliance 360 but questions their effectiveness absent direct league cooperation.

The NFL also questions whether the CFTC maintains sufficient staff for nationwide oversight. Without adequate resources for enforcement, even strong regulations cannot ensure game integrity or consumer protection.

Counterarguments and Limits of the Brief

The NFL’s position leaves room for federal oversight provided stronger safeguards are implemented. Should the Supreme Court side with Kalshi, the league states it would press the CFTC, operators, and Congress for additional measures before the 2027 season.

This caveat undercuts any absolute rejection of prediction markets. It frames the dispute as one over the adequacy of protections rather than the outright illegitimacy of the products. The brief does not quantify compliance costs or estimate market contraction under state-by-state licensing.

@joebrennanjr observed on X: “Funny to see the NFL filing a brief on the behalf of NJ and sports betting, given the 10 years they spent filing briefs against NJ and sports betting.” The observation highlights the shift in the league’s posture without resolving the underlying regulatory tension.

Operational Exposure for Prediction Market Platforms

Prediction market operators face divergent compliance obligations depending on the ultimate classification. State gambling licensure brings integrity monitoring agreements, geofencing, and consumer protection mandates already familiar to sportsbooks. CFTC oversight treats the products as swaps with different capital, reporting, and participant requirements.

The current circuit split allows some platforms to operate under federal authority in certain jurisdictions while others face state enforcement actions. This fragmentation increases legal risk and compliance overhead for multistate operators.

The NFL brief underscores that information-sharing with leagues is not optional for maintaining product integrity. Platforms without such arrangements may encounter resistance on data access and banned-participant enforcement, regardless of the regulator.

The Open Question for Supreme Court Review

The Supreme Court has not yet decided whether to grant certiorari. A decision to hear the case would produce binding nationwide precedent on the boundary between gambling and derivatives. Denial would leave the circuit split intact and encourage further litigation or legislative clarification.

Operators and investors must track the Court’s docket for any grant of review. The 2027 season deadline cited in the brief supplies a concrete timeline against which regulatory scenarios can be stress-tested. Platforms positioned across both potential regimes hold an advantage in adapting to whichever framework prevails.
