LeBron James has spent more than two decades building one of the most recognizable brands in professional sports. Now, the NBA superstar is taking steps to prevent an artificial intelligence company from exploiting that identity without his permission.
According to Front Office Sports, representatives for the Philadelphia 76ers forward have issued a cease-and-desist letter to Bron AI, a sports betting research application that used an AI-generated version of James in a promotional advertisement.
The commercial features a character resembling the four-time NBA champion, wearing a No. 23 basketball jersey with the name “Bron” across the back.
The character, whose voice also resembles James’, scrolls through potential sports wagers on a phone before encountering Phoenix Suns forward Dillon Brooks, a longtime on-court rival of the NBA’s all-time leading scorer.
Exclusive: LeBron James sent a cease and desist to the Bron AI sports betting app for this ad that evokes his name and uses his likeness without authorization.

The apparent connection to James was unmistakable, but his representatives insist that the association was never authorized.
“LeBron is in no way affiliated with this unauthorized use of his likeness,” a spokesperson told Front Office Sports.
The app, developed by PlayVision Inc., describes itself as a platform that combines information from sportsbooks and prediction markets to help users research betting opportunities. Its promotional campaign attracted plenty of attention, with the video accumulating more than 900,000 views in less than 24 hours.
But that publicity has now created a legal problem. In a letter obtained by Front Office Sports, attorney Lawrence Shire accused the company of improperly exploiting James’ identity to suggest a commercial relationship that does not exist.
James’ representatives also pointed to his existing exclusive endorsement agreement with prediction market platform Polymarket, emphasizing that the unauthorized advertisement could create confusion about his legitimate business relationships.
The letter demanded that Bron AI permanently discontinue using James’ identity, remove the advertisement and notify its users that the basketball superstar has no connection to the company.
James’ longtime media adviser, Adam Mendelsohn, was especially critical of the marketing strategy, suggesting the company may have deliberately provoked a legal response to generate publicity.
“These gimmicks never work because people see through it,” Mendelsohn told Front Office Sports.
The controversy has also extended beyond James. Luka Dončić’s representatives reportedly issued a separate cease-and-desist letter after the Lakers star’s image appeared in the same advertisement.
Following the legal complaints, the promotional video was removed from X. Bron AI and PlayVision had not publicly responded to requests for comment at the time of the original reporting.
No lawsuit has been confirmed, and a cease-and-desist letter does not itself constitute a court ruling.
Nevertheless, the dispute highlights an increasingly complicated issue for professional athletes: protecting their identities in an era when artificial intelligence can reproduce recognizable faces, voices and personalities without their participation.
