NBA Commissioner Adam Silver Demands Prediction Market Data Access to Combat Insider Trading and Preserve Game Integrity
NBA Commissioner Adam Silver seeks prediction market data access and control to address insider trading risks equivalent to sports betting concerns. The NFL's Supreme Court brief supports state gambling treatment with a minimum age of 21. Split court rulings on state versus federal oversight leave the regulatory path unresolved.
SCCG Take — Leagues require trading data to monitor for nonpublic information abuse. Platforms and regulators face pressure to reconcile integrity safeguards with unsettled federal-state boundaries.
The National Basketball Association is seeking access to prediction market data to detect potential insider trading and protect the integrity of its games. NBA Commissioner Adam Silver outlined these concerns in a CNBC interview, equating issues in prediction markets with those in traditional sports betting.
Silver stressed the priority of integrity across both formats, particularly for contracts involving nonpublic information on teams, players and coaches. He questioned certain trading activity as "odd behavior," including contracts on whether a coach will be fired.
Integrity Concerns Span Prediction Markets and Sports Betting
Speaking to CNBC’s Contessa Brewer on Squawk Box on Friday, October 9, Silver said: “Whether it’s called a prediction market, whether it’s sports betting, it’s the same issues for our league, and I think for all the leagues, there are issues around integrity first and foremost.”
Silver added: “We want access to that data. We also want control of the market.” These remarks arrived amid debate over whether prediction markets tied to sports outcomes should face state gambling regulations or federal financial oversight, as reported by Gambling News.
NFL Alignment and Persistent Legal Divisions
The National Football League (NFL) filed an amicus brief with the US Supreme Court supporting New Jersey regulators. The league argued that sports-related prediction market contracts fall under gambling laws, not federal rules governing financial swaps.
The NFL cited risks of market manipulation through contracts on player injuries and individual performance, where nonpublic information could be exploited. It called for a minimum trading age of 21, a threshold Silver endorsed while favoring federal regulation of the platforms.
Silver noted the NBA operates across roughly 40 regulatory jurisdictions and prefers a national framework over varying state rules. An appeals court ruled in September that states could regulate such markets, yet an Illinois decision temporarily blocked enforcement of state gambling laws against Kalshi and Coinbase. The conflicting rulings have left the status of sports-related prediction markets unsettled. Access to trading data would allow leagues to identify suspicious activity tied to confidential information.
