NBA adds AI betting monitoring and restricts wagers ahead of new season

The NBA has developed an internal AI platform to flag potentially suspicious betting as it restricts wagers offered by authorized sportsbooks ahead of the 2026–27 season. The coordinated measures, detailed in documents obtained by CNBC, also add betting education and protections against bettor harassment—pairing monitoring with limits on the bets themselves.

A memo sent October 16 to team presidents, general managers, integrity officers and lawyers describes the monitoring system. A separate letter to betting companies, including FanDuel, DraftKings and Fanatics, sets out restrictions on the markets they can offer. Together, the documents address both detecting suspicious activity and limiting opportunities for manipulation.

Game information meets individual betting data

The platform analyzes basketball data, injury reports, social media information about player availability and individual betting data. Its inputs therefore extend beyond what happens on the court: information about whether a player is available sits alongside records of wagering activity in the league’s monitoring system.

Dan Spillane, the NBA’s executive vice president of league governance and policy, wrote that the system is intended to help the league promptly identify and investigate potentially suspicious betting activity. That is a detection-and-investigation role: the stated purpose is to surface activity for scrutiny, not to treat a flag as proof of wrongdoing.

Fewer bets on outcomes one player can influence

The sportsbook restrictions target wagers that raise integrity concerns because one player can influence the outcome. CNBC described three categories covered by the league’s letter:

• Wagers on which player scores the first basket.
• Wagers involving players expected to play fewer than 12 minutes per game.
• Parlays that combine multiple bets on the same player’s underperformance.

Associated Press reporting published by The Washington Post also identifies restrictions on wagers about the opening tip and which players record a game’s first statistic. The restrictions change what sportsbooks may offer, rather than relying solely on monitoring bets after they have been placed.

Commissioner Adam Silver has linked the league’s integrity efforts to access to wagering information and authority over betting markets. Speaking to CNBC in Macao the previous week, he made clear that the NBA wants both.

So we want access to that data. We also want control over the markets.

Silver said prediction markets present the same integrity issues for the league as sports betting. But the memo does not specify how the restrictions would apply to prediction-market platforms. He also backed a national regulatory framework, saying the NBA currently deals with roughly 40 different jurisdictions.

Training teams and protecting players

The education measures include in-person training for each team from Charles Tillman, a former NFL player and retired FBI agent. Rookies will receive additional sports-betting training at the NBA Combine and during the required Rookie Transition program, adding instruction at two points in their entry into the league.

The player-protection measures address harassment and threats from bettors over game performance. The NBA updated its Fan Code of Conduct to emphasize that betting-related harassment is prohibited. It is also working with a third-party service to monitor and control harassing messages and has launched a text-message hotline to securely report threats.
