- A high-stakes Mayweather-Pacquiao rematch at the Sphere faces a major legal battle over contract breaches.
- Floyd Mayweather Jr. claims the bout is an exhibition, contradicting signed agreements for a professional fight
- Promoters warn of nine-figure damages as the September event’s status moves into the hands of lawyers
Turns out, that previously announced Sept. 19 Floyd Mayweather–Manny Pacquiao rematch at the Sphere may not be so confirmed after all. In fact, behind the scenes, the event is becoming a legal boxing match of its own.

Mathur says Mayweather signed three agreements, received deposits, and even “took a loan against the purse,” deepening his obligation. He also told the Review‑Journal the documentation is airtight, with full digital and physical signatures.
Fighting Words
The breach stems from the following comments Mayweather made during a March 28 autograph signing at Caesars Palace: “We don’t know exactly where the fight is going to be at… And this is not actually a fight, it’s an exhibition.” Those remarks contradicted the Netflix announcement framing the event as a sanctioned rematch and the Sphere’s own promotional posts.
Unlike the exhibition bouts both fighters have headlined in recent years, this event was contracted as a professional fight — meaning Mayweather’s 50-0 record is officially at stake. It was also positioned as the first professional boxing event ever to take place at the Sphere. Both are major selling points.
Pacquiao has pushed back, insisting the contract leaves no room for reinterpretation: “Yes, the contract that we signed is a real fight… He has to remember that.” He reiterated to multiple outlets: “No exhibition. It’s either a real fight or nothing.”
Mathur says Mayweather’s planned June exhibition against retired kickboxing champion Mike Zambidis also violates the agreement. He told ESPN the rematch was built to be a major global event and that Mayweather cannot “change terms last minute.”
According to the Review‑Journal, Mayweather faced an April 3 deadline to confirm he would honor the deal, followed by a 14‑day cure period. But the Sphere’s production timeline requires clarity within roughly 45 days. Mathur did not rule out replacing Mayweather if necessary.
He also warned that confidentiality may not hold if the dispute escalates: “It’s really like Floyd saying the car is black, but really the car is white… This is a black‑and‑white situation. It is 100 percent a pro fight.”
Netflix, the Sphere, and Mayweather have not commented further as the matter moves into the hands of lawyers.
