The NBA is actively engaging with a US federal regulator on developing an integrity framework for prediction markets, recently providing a detailed letter during a public comment period for proposed rulemaking. Dated April 30, the four-page correspondence was sent to the US Commodity Futures Trading Commission (CFTC) by Dan Spillane, the league's assistant general counsel for league governance and policy. In this submission, the NBA reiterated its stance that sports-event contracts must adhere to rigorous regulations to protect the integrity of the sport.
Spillane emphasized, "There is no higher priority for the NBA than protecting the integrity of our games and preserving public confidence in our league and in our sport." This submission followed Commissioner Adam Silver's disclosure that discussions with the CFTC regarding an integrity framework for basketball prediction-market trades had occurred. Should the NBA partner with the CFTC, it would mark a shift from its earlier position on prediction markets.
Spillane advocated for restrictions on Designated Contract Markets (DCMs), urging that athletes, game officials, and other team personnel be prohibited from trading contracts tied to their league's events. He also insisted that DCMs must assist with integrity investigations by sports governing bodies and provide information to leagues during inquiries about suspicious trading.
Concerns over insider trading surfaced earlier this week when a US Army special forces soldier, who allegedly earned approximately $400,000 from a Polymarket trade related to Venezuelan President Nicolas Maduro's potential ousting, pleaded not guilty to utilizing classified information. This incident highlights the risks associated with insider trading in prediction markets. In response, Polymarket announced it would utilize Chainalysis, a blockchain data platform, to enhance market integrity on its DCM DeFi platform.
Spillane stressed the importance of using verified league data in the betting settlement process, underscoring that DCMs should leverage official data to maintain consumer trust.
On April 27, Silver commended the CFTC for prioritizing integrity in its collaboration with sports leagues. Although the NBA has not formalized an integrity framework, Silver suggested its approach might align with a recent Memorandum of Understanding signed by the CFTC and Major League Baseball. If successful, this framework could lead to the NBA establishing a marketing agreement with a prediction market operator such as Kalshi or Polymarket. Silver noted, "We aren’t necessarily adverse to entering into licensing deals with them, but the league’s number one role is to ensure the integrity of the competition. That’s what we’re most focused on right now."
These comments came against the backdrop of ongoing legal troubles within the NBA, as two figures from the league appeared in Brooklyn federal court related to an illegal betting scandal. On Monday, Assistant US Attorney Kaitlin Farrell indicated that more charges against former Miami Heat player Terry Rozier could be forthcoming, as he faces accusations including honest services fraud and bribery. Rozier is implicated in US vs. Earnest, a case connected to fraudulent activities targeting major sportsbooks. Meanwhile, Damon Jones, a former assistant with the Los Angeles Lakers, pleaded guilty to conspiracy to commit wire fraud, admitting to providing insider information to bettors. He is scheduled for sentencing next January.
