Floyd Mayweather is getting hit with a lawsuit that’s basically the boxing equivalent of getting caught red-handed with your hand in the cookie jar.

CSI Entertainment claims they paid the legendary fighter $4.65 million in advance money for exclusive rights to two mega fights, and now he’s allegedly ghosting them completely.

The promoters say they handed over $4.5 million to Mayweather’s management company Frist Apex Ventures, with Floyd personally signing off on the whole deal, and then he just walked away like none of it ever happened.

Here’s where it gets messy. The day after CSI cut them a separate $150,000 advance check, Mayweather announced he was fighting Greek kickboxer Mike Zambidis instead of Mike Tyson, and he did it with a completely different promoter.

CSI says they were supposed to have exclusive rights to an exhibition match against Tyson, followed by a rematch with Manny Pacquiao, in which Floyd would risk his unblemished 50-0 record.

But that’s not even the worst part.

According to TMZ, Mayweather secretly signed a separate deal to stream the Pacquiao fight on Netflix from the Sphere in Las Vegas, completely violating CSI’s exclusive agreement.

CSI is asking the court to stop the Zambidis fight scheduled for next week and block the Netflix event.

They’re also seeking damages, or at least their money back, claiming they have already invested significant time and resources in promoting both fights.

The situation mirrors Mayweather’s ongoing legal battles that have been piling up since 2025.

He’s currently facing two felony charges in Las Vegas for allegedly writing a $200,000 bad check in December 2024 to buy a luxury watch from Gold and Beyond.

The charges are theft and drawing a check with intent to defraud, and his hearing is scheduled for September.

Beyond that, he’s also suing his former business manager, Jona Rechnitz, for $175 million, alleging a multi-year fraud scheme involving over $100 million in jewelry, his Gulfstream jet, and real estate deals that went sideways.

Mayweather is also suing Showtime for $340 million, claiming the jerked him out of his earnings.
