In recent weeks, the US Supreme Court has been presented with multiple briefs urging it to address a significant case that could influence the future of sports event contracts. With nearly $1 trillion in notional value at stake, the situation has been described as a critical moment for the sports wagering and derivatives sectors. On Wednesday, the NFL lent its voice to the discourse by filing an amicus brief with the Court.
The NFL's 32-page brief, co-authored by former US Attorney General William Barr, urged the Court to review the case of Flaherty v. KalshiEx, LLC, emphasizing the importance of maintaining the integrity of professional sports and safeguarding market participants. The NFL stated that achieving clarity in sports prediction markets is vital for both sports integrity and consumer protection within the industry. As the US Commodity Futures Trading Commission (CFTC) seeks exclusive regulatory authority over derivatives, the NFL has been in discussions with prediction market operators recently.
However, the brief indicated that the NFL and various operators have encountered resistance to its calls for the implementation of necessary safeguards for sports event contracts.
In the document, the NFL specified several types of event contracts it finds objectionable. This echoed its earlier stance raised in a brief submitted to the CFTC during a comment period on proposed rules regarding derivatives. Contracts deemed inappropriate include bets on whether a kicker will miss a field goal, which penalties will occur in games, and various wagers unrelated to the game itself, like phrases that might be uttered during broadcasts.
The NFL voiced concerns over whether the CFTC possesses the required regulatory framework, oversight capacity, and enforcement resources to ensure prediction markets do not compromise game integrity.
Two prominent prediction market operators, Kalshi and Polymarket, both highlighted their commitment to market integrity. Polymarket stated it shares the NFL's concern about preserving game integrity and is continually enhancing its market surveillance tools. Kalshi expressed its willingness to collaborate with the NFL on maintaining market integrity, asserting that it actively monitors sports-related markets.
During an exhibition game in Macau, NBA Commissioner Adam Silver addressed issues of integrity in prediction markets. He pointed out the need for data collection when unusual behavior is noticed in the markets. Unlike the NFL, which supports state-level regulation, Silver advocates for a federal standard to govern sports wagering and predictions.
At the Predict 2026 conference held in Midtown Manhattan, market integrity was a central topic. Sean Patrick Maloney, President of the Coalition for Prediction Markets, led a panel discussing strategies to combat insider trading. Maloney, a former Congressman, recently testified before the Senate on issues surrounding sports wagering and predictions. His focus at the conference followed the arrest of a US Army special forces soldier for insider trading, which brought increased attention to these matters.
The soldier, Gannon Van Dyke, was indicted for misusing classified government information for personal financial gain, reportedly making around $400,000 from trades on Polymarket based on the prediction that Venezuelan President Nicolas Maduro would be ousted by a certain date. If found guilty, he faces over 20 years in prison. Maloney indicated that a strict sentence should be considered for anyone proved to have leaked classified information, emphasizing the severity of misusing national security details.
Additionally, Jack Murphy, a senior counsel, pointed out that the Van Dyke case is among several insider trading incidents being closely monitored within the predictions sector, which also includes notable cases involving a Google engineer and a former member of Congress.
In legal developments, the Seminole Tribe of Florida filed a high-profile lawsuit against DraftKings earlier this week. The tribe's 72-page complaint, submitted in Broward County, alleges that DraftKings is illegally conducting sports betting in Florida, violating the tribe's gaming compact established in 2021. The lawsuit particularly criticizes DraftKings’ "Super App," which integrates various gaming services, arguing that it undermines Florida’s revenue and necessary consumer protections.
DraftKings responded by asserting that its prediction market operations comply with the Commodity Exchange Act's federal regulations. The company acknowledged the Seminole Tribe's significance but remains assured of its legal stance on sports event contracts.
In other news, Kalshi announced partnerships with four tribes, including three in California and one in Oklahoma.
