NBA tightens betting rules and deploys AI to flag suspicious wagers
The league is restricting certain prop bets and parlays, building an internal AI monitoring platform and expanding education as Commissioner Adam Silver seeks more control over wagering markets.
At a glance
- The NBA is restricting bets on first basket scorer, players expected to play under 12 minutes and same-player parlays.
- The league has built an internal AI platform to analyze basketball, injury, social media and betting data for suspicious activity.
- Commissioner Adam Silver wants more wagering data access and a national framework for sports betting regulation.
The NBA is tightening restrictions on bets offered by its authorized gambling partners and deploying artificial intelligence to identify suspicious wagering ahead of the 2026-27 season, according to two documents obtained by CNBC.
The measures reflect Commissioner Adam Silver's push for greater access to wagering data and more control over the types of markets offered on league games. Silver said his concerns also extend to prediction markets.
"For us, 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," Silver told CNBC last week in Macao. "There's issues around integrity first and foremost."
Bet restrictions
In a letter to sports betting companies including FanDuel, DraftKings and Fanatics, the NBA placed restrictions on wagers on which player scores the first basket, wagers on players expected to play less than 12 minutes per game, and parlays combining multiple bets on the same player's underperformance. The league said those bets can raise integrity concerns because a single player can influence the outcome.
The changes follow gambling-related cases involving former players Jontay Porter, Terry Rozier and Damon Jones, and former coach and player Chauncey Billups.
AI monitoring platform
A separate memo sent Friday to team presidents, general managers, integrity officers and lawyers said the NBA has developed an internal AI-based monitoring platform. The system analyzes basketball data, injury reports, social media information about player availability and individual betting data. It is designed to help the league "promptly identify and investigate potentially suspicious betting activity," according to the memo from Dan Spillane, the NBA's executive vice president of league governance and policy.
Training and harassment protections
The league is increasing training and education around sports betting. Former NFL player and retired FBI agent Charles Tillman will provide in-person training to each team, the memo said. NBA rookies will receive training at the NBA Combine and during the required Rookie Transition program.
The NBA also updated its Fan Code of Conduct to highlight the prohibition on betting-related harassment, is partnering with a third-party service provider to monitor and control harassing messages, and launched a text message-based hotline to securely report threats.
The memo does not specify how the restrictions would apply to prediction market platforms. In Macao, Silver said he favors a national framework for federal regulation of sports betting, noting that roughly 40 different jurisdictions currently regulate the league.
