Floyd Mayweather’s legal troubles are mounting, and the latest details paint a troubling picture for the former pound-for-pound champion. A new lawsuit has surfaced tied to an alleged scheme surrounding a planned matchup with Mike Tyson.
According to reports, a company called CSI secured the exclusive rights to promote Mayweather in a series of match, beginning with a bout against Mike Tyson, followed by a blockbuster rematch with Manny Pacquiao.
The Tyson deal would pay Mayweather $14 million, including a $2 million advance, with the remaining $12 million due one day after the match. The Pacquiao bout was valued at $35 million base, with the potential for 20% of pay-per-view revenues on top of that. A $50 million buyout was also on the table if the match moved to a broadcasting platform without a pay-per-view component.
The contract explicitly prohibited Mayweather from competing against anyone else before the Tyson bout. Despite this, he allegedly signed a separate deal with a company called Ever Wonder Studios in December 2025 to fight Pacquiao on Netflix, cutting CSI out entirely.
That new deal paid him less, approximately $24.75 million, suggesting he walked away from a significantly better arrangement. He also reportedly scheduled an unauthorized match against Greek kickboxer Mike Zambidis in Greece, further violating his contractual obligations.
When CSI discovered the Zambidis match via an Instagram post in February 2026, they moved to amend the agreement rather than immediately pursue legal action. They asked for their $2.5 million advance back and sought $5 million from Ever Wonder Studios in exchange for rights to Mayweather’s next fight after Pacquiao. That resolution quickly fell apart.
Adding to the story, Mayweather reportedly demanded $150,000 of his advance payment in physical cash rather than a bank transfer. CSI’s owners flew from the East Coast to the Peninsula Hotel in Beverly Hills to deliver the money in person.
When they arrived, Mayweather did not show up and instead sent a female companion to receive and count the cash on his behalf. A photo from the exchange reportedly shows the money being counted at a hotel conference room table, with the bills arriving in a custom Louis Vuitton bag stamped with the CSI logo.
CSI is now seeking a permanent injunction to block Mayweather from competing against Zambidis and to enforce the original agreements, requiring him to compete against Tyson first and Pacquiao after that.
Beyond the lawsuits, observers and commentators online have been questioning the state of Mayweather’s finances. While his career earnings are estimated around one billion dollars, a significant portion went to taxes, management fees, and a famously extravagant lifestyle.
Reports indicate he spends between $1 million and $5 million per month, owns over a hundred cars, has pawned tens of millions in jewelry for liquidity, and has faced accusations that his former manager embezzled funds. His net worth and his actual available cash appear to be very different figures, and the gap seems to be catching up with him.
