Boxing icon Floyd Mayweather has launched a massive legal fight outside the ring. The undefeated superstar filed a nine-figure lawsuit against Showtime and former Showtime Sports president Stephen Espinoza, alleging that hundreds of millions of dollars from his fight earnings—including his blockbuster bout with Conor McGregor—never made it to him.
Mayweather filed the lawsuit Tuesday in Los Angeles, accusing Showtime and Espinoza of participating in what he describes as a long-running scheme that cost him roughly $340 million. The filing centers on Mayweather’s biggest money fights, including his 2015 clash with Manny Pacquiao and his 2017 crossover spectacle against McGregor.
According to the lawsuit, Mayweather is seeking to “recover hundreds of millions of dollars in misappropriated funds and damages resulting from a long-running and elaborate scheme of financial fraud,” along with compensation for “lost investment growth” tied to the missing earnings.
The complaint alleges that funds intended for Mayweather were diverted to accounts controlled by his former manager and advisor, Al Haymon. Out of an estimated $1.2 billion generated during Mayweather’s career, the lawsuit claims at least $340 million remains unaccounted for.
Mayweather’s legal team also accuses Haymon of financial manipulation, alleging that portions of Mayweather’s fight revenue were rerouted under false pretenses and placed into undisclosed accounts. The filing claims Haymon paid himself and associates large sums without authorization while providing Mayweather with only partial financial records.
When Mayweather’s new representatives reportedly requested full documentation related to the Pacquiao and McGregor fights, the lawsuit alleges Showtime was “unable or unwilling” to produce complete records.
In one instance, the filing claims Haymon said certain documents were “lost due to a flood,” while Showtime allegedly stated that key files had been moved off-site following the downsizing—and eventual elimination—of Showtime Sports.
Despite the allegations, Haymon is notably not listed as a defendant in the lawsuit.
Mayweather signed an exclusive deal with Showtime in 2013 after leaving HBO and fought under the network until his retirement from professional boxing in 2017. He retired with a perfect 50-0 record and multiple world titles before transitioning into lucrative exhibition bouts against names like Logan Paul and Mikuru Asakura.
As of now, Showtime and Espinoza have not publicly responded to the lawsuit.
Outside the courtroom, Mayweather continues to tease a return to the ring. He is reportedly preparing for a high-profile bout with heavyweight legend Mike Tyson, though no date or venue has been announced. He has also been loosely linked to a potential matchup with kickboxing star Mike Zambidis, but that fight remains unconfirmed.
