NFL Backs New Jersey Authorities in Supreme Court Case Over Prediction Market Sports Bets
The National Football League (NFL) has largely sided with New Jersey officials in their petition for the US Supreme Court to consider a case that challenges the jurisdiction over sports bets made through prediction market platforms. In an amicus brief filed Wednesday, the NFL endorsed New Jersey's argument that such platforms should fall under state regulation rather than federal Commodity Futures Trading Commission (CFTC) authority. The case could have broad implications for legal oversight, game integrity, and consumer protections in sports betting via prediction markets.
NFL files amicus brief supporting New Jersey's Supreme Court petition
On Wednesday, the National Football League submitted an amicus brief to the US Supreme Court, endorsing New Jersey Attorney General Jennifer Davenport and interim gaming enforcement director Mary Jo Flaherty's petition for a writ of certiorari in their case against prediction market platform Kalshi. The NFL aligned with New Jersey’s arguments that contracts on prediction market platforms are misclassified as “swaps” under Commodity Futures Trading Commission (CFTC) jurisdiction, and that Supreme Court review is necessary to protect game integrity and safeguard consumers.
Concerns over manipulation and threats to game integrity
The NFL emphasized that many sports-event contracts offered by Kalshi and similar platforms are highly vulnerable to manipulation. The league argued such contracts could be influenced by a single individual—be it a player, coach, or official—altering game outcomes or performance and thus threatening the integrity of sports competitions.
Supporting this concern, the NFL cited data showing that on the NFL's first Sunday of the season, over $1.8 billion of the $3.3 billion total traded on prediction markets related to football, illustrating the significant exposure of the sport to this segment.
Regulatory issues and federal versus state authority
The NFL also highlighted deficiencies in the Commodity Futures Trading Commission’s oversight, arguing that sensible protections for these event contracts are lacking. The case poses a critical question regarding whether federal or state authorities should regulate sports betting via prediction markets.
As of Thursday, the Supreme Court had not decided whether to take up the case. Kalshi was granted an extension until November 9 to respond to questions on jurisdiction, potential contract manipulation, and consumer protection.
Broad support from states and Washington D.C.
In addition to NFL support, 39 US states and the District of Columbia filed an amicus brief backing New Jersey’s position. They described the dispute between CFTC and state regulators as a “national turf war” that necessitates Supreme Court intervention.
The brief warned that delay would exacerbate federal-state regulatory conflicts, generating uncertainty about applicable laws and authorities. It urged the Court to resolve the split among circuits, clarify the CFTC’s authority, and provide essential guidance.
Kalshi’s stance and potential future appeals
Kalshi spokesperson Dani Lever told Cointelegraph that the company resists regulation by “50 different regulators” across the states. The Kalshi case marks a leading Supreme Court challenge, but comparable cases continue to arise at state levels and might also proceed to higher courts in the future.
Why it matters
The Kalshi case and NFL’s involvement underscore a crucial legal battle over regulatory authority on prediction market platforms, particularly in the rapidly expanding area of sports betting. The decision will impact consumer protections, game integrity, and legal clarity faced by these emerging markets. Support from the NFL and numerous states highlights that the dispute transcends one company, reflecting a broader conflict between state and federal regulators needing definitive Supreme Court resolution to establish a consistent legal framework.
