NBA Opens Leaguewide Review of Prop Bets, Injury Reports and AI Monitoring After Insider Gambling Charges

The National Basketball Association has initiated an extensive audit of wagering practices across all 30 franchises after a federal indictment alleged that confidential player information was leaked to gamblers. A league memo distributed on Monday outlines a multilayered plan that will scrutinize proposition bets, tighten injury-reporting procedures and expand the use of artificial intelligence to spot suspicious betting patterns.

The document, signed by NBA General Counsel Rick Buchanan and Executive Vice President Dan Spillane, was sent to governors, team presidents, general managers and legal counsels. It states that the move is designed to “protect the integrity of the NBA and our affiliated leagues” at a time when legalized sports betting has become deeply embedded in the U.S. sports landscape.

Focus on individual player wagers

At the center of the review are proposition bets—wagers on the statistical performance of individual players. Legal sportsbooks such as FanDuel and DraftKings routinely offer markets on points, rebounds, assists and a range of other individual metrics. The league memo notes that these bets raise “heightened integrity concerns” because a single player can influence the outcome without affecting the final score. Officials will evaluate whether additional limits or outright restrictions should be placed on certain prop offerings.

Heightened attention to injury disclosures

The NBA will also revisit its rules on public injury reports. Transparent, timely injury information is considered essential to both competitive balance and betting markets, yet any inaccuracies or premature leaks create opportunities for exploitation. The league plans to review how injuries are reported, who has access to internal data and whether stricter penalties are warranted for breaches.

Artificial intelligence to flag irregular activity

As part of the initiative, the league intends to enhance its integrity monitoring systems by leveraging artificial intelligence. By combining data from licensed betting operators, social-media chatter and internal analytics, AI tools are expected to identify wagers that deviate from normal market behavior and may indicate the use of inside information.

Indictment involving Rozier and alleged co-conspirators

The policy overhaul follows an indictment unsealed last week in U.S. District Court in Brooklyn. Six individuals, including Miami Heat guard Terry Rozier, were charged with conspiracy to commit wire fraud and money laundering. Prosecutors claim the defendants possessed non-public information from NBA players and coaches and used it to place profitable prop bets with licensed sportsbooks.

According to court filings, Rozier allegedly told a longtime acquaintance in March 2023—while still with the Charlotte Hornets—that he planned to exit a game early because of an injury. That tip reportedly led to more than $200,000 in prop wagers on Rozier’s statistical “unders,” many of which paid out after he left the game nine minutes into the first quarter. Rozier’s attorney has denied any wrongdoing, asserting that the player “is not a gambler” and intends to contest the charges.

Billups identified but not charged in main case

The same indictment refers to an unnamed “Co-Conspirator 8” whose career details match Portland Trail Blazers head coach and Hall of Fame player Chauncey Billups. The document alleges that in March 2023, the individual told a defendant that Portland intended to lose a contest against the Chicago Bulls to improve its draft position, prompting approximately $100,000 in bets on a Trail Blazers defeat. Billups has not been charged in this matter, but he faces a separate indictment accusing him of involvement in a high-stakes poker cheating scheme. His lawyer maintains that Billups “would never gamble on basketball games or provide insider information.”

Following their arrests on Thursday, both Rozier and Billups were placed on leave by the league.

Previous action after Jontay Porter probe

This is not the NBA’s first response to betting integrity concerns. In October 2024, after questions arose about wagers linked to Toronto Raptors forward Jontay Porter, the league directed its gaming partners to remove prop markets involving two-way and 10-day contract players. Officials argued that lower-paid players were more susceptible to manipulation. Porter pleaded guilty in July 2024 to conspiracy to commit wire fraud.

Industry reaction

Sportsbook operators have indicated support for tighter safeguards. Matt King, chief executive of Fanatics Betting and Gaming, said his company maintains “constant communication” with leagues on integrity matters. He added that Fanatics immediately complied when the NBA requested the removal of prop bets on two-way contract players, calling it “common-sense regulation.”

This cooperative approach is expected to continue as the NBA expands its monitoring capabilities. The Department of Justice, which brought the recent charges, has emphasized in prior statements that protecting sports integrity remains a federal priority; background on the agency’s position can be found on the U.S. Department of Justice website.

The league’s internal review will assess training programs for players, coaches and staff, reinforce policies that guard against harassment by bettors and determine whether additional regulatory measures should be recommended to state authorities. No timeline for completion of the review has been announced.
