Curtis “50 Cent” Jackson, the United States rapper and businessman, has mocked Floyd Mayweather Jr., the United States boxing star, after Mayweather filed a $340 million lawsuit linked to his past fights on Showtime, a United States premium television brand.
On Thursday, 5 February 2026, Yahoo News reported that the lawsuit was filed on Tuesday, 3 February 2026, in a California state court in the United States. The case accuses Showtime and its former sports president, Stephen Espinoza, of what the filing describes as a long-running financial fraud scheme that allegedly diverted millions of dollars meant for Mayweather.
According to the complaint, money connected to some of Mayweather’s biggest events was wrongly routed into accounts controlled by his former manager, Al Haymon. The lawsuit claims the disputed payments include proceeds linked to major fights such as Mayweather’s bout with Manny Pacquiao, the Filipino boxing icon, and his blockbuster match with Conor McGregor, the Irish mixed martial arts star.
Haymon was not listed as a defendant in the lawsuit.
Mayweather’s Lawyer And Paramount Respond
Mayweather’s lawyer, Bobby Samini, said the boxer is taking the dispute to court because he believes he was not paid what he earned from the revenue he helped generate. Samini said Mayweather “generated hundreds of millions of dollars in revenue for Showtime” and is now seeking to recover what he says is owed to him, adding that the retired champion will “go the distance in the courtroom” as he did in the ring.
Paramount, the United States media company that is Showtime’s parent firm, rejected the allegations. A spokesperson told The Hollywood Reporter, the United States entertainment trade publication, “These baseless claims lack legal or factual merit. We strongly reject them and will respond accordingly through the court process.”
Mayweather, 48, is widely seen as one of boxing’s all-time greats, known for defensive skill, sharp technique, and an unbeaten professional record of 50 wins and 0 losses. He won world titles in five weight divisions and headlined some of the most profitable pay-per-view events in the sport.
Although he has retired from professional boxing, he has continued to take part in exhibition bouts. The report also referenced a proposed exhibition fight with Mike Tyson, the 59-year-old former United States heavyweight champion, which was originally scheduled for spring 2026. Tyson recently predicted, “He’s going to get knocked out.”
50 Cent Steps Into The Dispute
Jackson, who has had a long and often hostile public relationship with Mayweather, joined the discussion after news of the lawsuit spread.
On Wednesday, 4 February 2026, he posted on Instagram, the social media platform, to ridicule the boxer over the legal fight. In the post, Jackson claimed Mayweather had been cheated out of about $320 million and said Mayweather should have allowed him to review the contracts. He also urged Mayweather to “lace up” ahead of a possible bout with Tyson, and he suggested Mayweather could pursue a big-money fight with Terence “Bud” Crawford, the United States boxing champion, as a way to recover the losses he alleges.
Fans responded quickly. Bow Wow, the United States rapper and entertainer, reacted with a skull emoji, while another social media user wrote, “50 will never let his opps get a pass,” a comment pointing to Jackson’s reputation for persistent online trolling.
The dispute between the two celebrities dates back to the 2000s. The report said a financial disagreement in 2012 created a serious rift between them after they had once been friends.
Their feud also includes a widely discussed incident in 2014, when Jackson challenged Mayweather to read a page from the children’s book The Cat in the Hat or from the Harry Potter series, promising to donate $750,000 to one of Mayweather’s charities if he did so.
Over the years, Jackson has also claimed he played a key role during Mayweather’s “Money” era and said he influenced Dana White, the chief executive of the Ultimate Fighting Championship (UFC), the United States mixed martial arts organisation, to support the Mayweather versus McGregor superfight.
What The Lawsuit Claims
The lawsuit argues that even one of the most financially successful athletes of the modern era can still face major disputes over earnings. The report said Mayweather has been credited in public reports with earning about $1.2 billion in fight purses, yet he is now alleging that a large portion of his income is missing.
In the California filing, Mayweather claims that nearly 40 percent of his career earnings cannot be properly accounted for, which he blames on unclear bookkeeping practices during his Showtime contract period from 2013 to 2015.
That agreement, according to the report, included nine-figure payouts tied to major fights, including bouts against Canelo Alvarez, the Mexican boxing star, and Manny Pacquiao. The filing also states that the Pacquiao fight alone generated $410 million in revenue.
As the court battle develops, Jackson has continued to taunt Mayweather, suggesting the boxer may need to return to the ring, not only for an exhibition with Tyson but also possibly for a fight with Crawford, to make up for the losses he says he suffered.
Whether the fight plays out in a courtroom or in a ring, the drama around “Money” Mayweather appears far from over.
