Manny Pacquiao and Floyd Mayweather will run it back one last time

More than a decade after their record-shattering first encounter, Floyd Mayweather Jr. and Manny Pacquiao are set to meet again in a professional boxing rematch on September 19 at the Sphere in Las Vegas. The bout will stream live worldwide on Netflix, marking another bold step in the evolution of how major boxing events are delivered to global audiences.

The announcement reignites one of the most lucrative and polarizing rivalries in modern sports history, a matchup that once captivated the world and generated unprecedented revenue. On May 2, 2015, Mayweather and Pacquiao finally squared off after years of negotiations, delays and mounting public anticipation. The bout ended in a unanimous decision victory for Mayweather, preserving his undefeated record. While critics argued the fight did not live up to its immense hype inside the ring, its commercial success was undeniable.

The contest generated 4.6 million pay-per-view buys in the United States and more than $410 million in revenue, both records that still stand. The event also set a gate record with $72.2 million in ticket sales cementing its place as the most financially successful fight in boxing history.

Mayweather, 49-0 as a professional, had previously announced his retirement but recently signaled his return to competition following his 2026 exhibition against Mike Tyson. He has since entered a multifight partnership with CSI Sports/Fight Sports, positioning himself for another high-profile run.

“I already fought and beat Manny once,” Mayweather said in a statement. “This time will be the same result.”

Pacquiao, meanwhile, ended his own retirement last July when he faced then-WBC welterweight champion Mario Barrios, battling to a majority draw. The 45-year-old Filipino icon will also compete in an exhibition bout against Ruslan Provodnikov on April 18 at the Thomas & Mack Center.

“Floyd and I gave the world what remains the biggest fight in boxing history,” Pacquiao said. “The fans have waited long enough they deserve this rematch, and it will be even bigger now that it will be streamed live globally on Netflix. I want Floyd to live with the one loss on his professional record and always remember who gave it to him.”

As always, Pacquiao added, he dedicates the fight to his fellow Filipinos around the world and to bringing glory to the Philippines. Unlike their first meeting, the rematch will not be a traditional pay-per-view event. Instead, Netflix will stream the fight to its more than 325 million global subscribers, eliminating the PPV barrier and potentially expanding the audience far beyond what was possible in 2015.

Several key elements remain unknown. The weight class for the rematch has not been announced, nor has the number of rounds. Given both fighters’ age and time away from traditional championship contention, those details will likely shape expectations.

The event will be produced by Ever Wonder Studio, Hidden Empire and Limitless X Holdings. Promotional duties will be handled by Manny Pacquiao Promotions and Mayweather Promotions in partnership with CSI Sports/Fight Sports. For Mayweather, the fight offers another opportunity to reinforce his undefeated legacy and silence critics who felt the first bout lacked fireworks. For Pacquiao, it is a chance at redemption and perhaps the most dramatic way possible to hand his longtime rival a first professional loss.
