Floyd Mayweather Jr., boxing’s undefeated champion inside the ring and one of its richest figures outside it, has filed a sweeping lawsuit against Showtime Networks, alleging the broadcaster helped divert hundreds of millions of dollars in fight earnings to his former manager.
The complaint, lodged Tuesday in California state court, accuses Showtime of playing a role in a yearslong scheme of “financial manipulation and self-dealing” orchestrated by ex-manager Al Haymon. Mayweather claims vast sums from his blockbuster bouts were siphoned into accounts he did not control.
He is seeking at least $340 million on claims that include breach of fiduciary duty and fraud.
The Richest Fighter in History
With career earnings estimated at roughly $1.2 billion, Mayweather stands as the highest-paid boxer of all time. He secured guaranteed purses of $100 million for his megafights against Conor McGregor and Manny Pacquiao — figures that exclude his share of the immense pay-per-view profits those record-setting events generated.
Known for flaunting his wealth, Mayweather has frequently displayed stacks of cash in public appearances and social media posts, cultivating an image of financial invincibility.
But in the lawsuit, he portrays himself not as a mogul in control — but as an athlete kept in the dark.
