Floyd Mayweather is widely considered the highest-paid boxer in history.
The 50-0 superstar amassed over $1 billion in fight earnings during his illustrious career. Mayweather pulled in nine-figure sums for his bouts against Conor McGregor and Manny Pacquiao.
However, it appears that not every penny ended up in the American icon’s bank account.
Floyd Mayweather files lawsuit against Showtime

TMZ Sports reported on Tuesday that Floyd Mayweather has filed a $340 million lawsuit. The lawsuit, filed in California, claims the funds are tied to “a long-running and elaborate scheme of financial fraud, allegedly perpetrated by his longtime advisor Al Haymon.”
Mayweather also alleges that Haymon received support from Showtime and former Showtime Sports president Stephen Espinoza. Both Showtime and Espinoza are named as defendants in the suit.
Despite these accusations, Haymon himself is not a defendant in the case.
The suit cites several major fights, including those against Manny Pacquiao and Conor McGregor. Mayweather claims that money owed to him was instead sent directly to accounts controlled by Haymon.
Mayweather is pursuing damages for aiding and abetting breach of fiduciary duty, civil conspiracy to commit fraud, conversion, and unjust enrichment.
Beyond the missing $340 million, he’s also seeking additional punitive damages in court.
