Lawsuit Reveals Exactly How Much Floyd Mayweather Could Earn From Upcoming Manny Pacquiao And Mike Tyson Fights

Floyd Mayweather's financial life seems to take a weird twist every other week. And here's the latest…

It all started back in January when we covered a lengthy investigation into Floyd Mayweather's finances that raised questions about loans, liens, foreclosures, unpaid bills, and asset sales. A month later, Floyd filed a $340 million lawsuit against Showtime, claiming a huge portion of his career earnings had been diverted into accounts he did not control. We later paid $19 to download the full complaint and broke down the specific allegations.

Then came the $330,000 unpaid rent lawsuit tied to a $100,000-per-month luxury Manhattan apartment. Then came a reported $7.3 million IRS lien. Then came Floyd's own $175 million lawsuit against former business associates, involving claims about missing money, Manhattan real estate, a Gulfstream jet, and $100 million in jewelry. And last week, Floyd was charged with two felonies in Nevada over an alleged bad check used to buy a $200,000 watch.

That's the bad news. There is some good news.

Floyd does have some major financial lifelines on the horizon. Specifically, several upcoming boxing matches that have the potential to be extremely lucrative. And thanks to a new lawsuit filed against him in federal court, we now know exactly how lucrative these lifelines could be.

Floyd is currently being sued by a company called CSI Sports Events. CSI apparently contracted Mayweather to participate in two major upcoming fights: an exhibition against Mike Tyson and a rematch against Manny Pacquiao. CSI claims it had exclusive rights to promote and produce those events, and that Mayweather breached the agreement by agreeing to fight Greek kickboxer Mike Zambidis on June 27 in Athens.

CSI is seeking an emergency injunction to stop the Zambidis fight, plus restitution from Mayweather and Frist Apex Ventures. But the most interesting part of the lawsuit is what it reveals about Floyd's future fight money.

The Mike Tyson Payday

According to the CSI lawsuit, Floyd Mayweather was supposed to earn $14 million for an exhibition fight against Mike Tyson.

The lawsuit claims Floyd had already received a $2 million advance tied to the Tyson event.

The Tyson exhibition was originally announced as a spring 2026 event. At one point, the fight was reportedly being planned for the Democratic Republic of Congo. No final date or location was ever formally announced.

The lawsuit says Tyson later injured his hand and could not compete by a May 30 deadline. However, CSI claims the contract allowed a six-month window to reschedule the Tyson fight before Mayweather could participate in an interim bout. That is why CSI is trying to stop the Zambidis fight in Greece. CSI claims the Greece fight would improperly become Floyd's return fight before the Tyson obligation was satisfied.

The Manny Pacquiao Payday

According to the CSI lawsuit, Floyd had two payment options for the fight:

1. $35 million plus 20% of pay-per-view revenue
2. $50 million flat fee if there was no pay-per-view component.

The contract allegedly also included a backup plan if Pacquiao was unavailable. In that scenario, Floyd would fight another suitable opponent for either $20 million plus 20% of pay-per-view revenue, or a $25 million buyout.

The Netflix Twist

According to the lawsuit, the Pacquiao rematch became more complicated when Mayweather allegedly entered into a separate agreement with EverWonder for a Pacquiao fight on Netflix.

That deal allegedly promised Floyd $24.75 million, plus a potential $3.75 million bonus, plus a $2.75 million advance.

Netflix announced in February that Mayweather and Pacquiao would meet in a September 19 rematch at The Sphere in Las Vegas. But according to CSI, that Netflix/EverWonder arrangement conflicted with CSI's exclusive rights.

CSI and EverWonder reportedly tried to work out a solution in which Tyson would go first, Pacquiao would happen in the fall at The Sphere on Netflix, and CSI would receive certain billing and rights. But CSI claims Frist Apex Ventures, a co-defendant in the lawsuit, never repaid an advance required as part of that arrangement.

The Frist Apex Connection

Frist Apex Ventures is also a key defendant in Floyd's own $175 million lawsuit. In that case, Floyd claims former business associates siphoned away cash, real estate proceeds, jewelry, aircraft proceeds, settlement funds, and income streams.

In the CSI lawsuit, however, Frist Apex is described as Mayweather's representative. CSI claims Frist Apex had authority to enter the Tyson deal on Floyd's behalf.

The lawsuit also mentions Jona Rechnitz, another central figure in Floyd's $175 million lawsuit. According to the CSI complaint, Mayweather allegedly refused, through then-business manager Rechnitz, to make a November social media announcement about his return to boxing because he was allegedly in the process of selling the same rights to another party.

That overlap makes this case especially interesting. Some of the same people and entities Floyd is now suing are also tied to the fight contracts that could generate his next major paydays.

CSI is reportedly seeking $6.65 million in restitution from Mayweather and Frist Apex. But the real money is much larger than the restitution demand.

Against the backdrop of tax liens, lawsuits, unpaid-bill allegations, asset disputes, and felony charges over an alleged bad check, these fights looked like potential liquidity events. Now, those very lifelines are tangled in litigation.

Mayweather and his representatives have not yet publicly responded to the lawsuit. As always, these are allegations, and the defendants will have their chance to respond in court.
