Floyd Mayweather is coming out of retirement for a rematch against Manny Pacquiao on Sept. 16 at The Sphere in Las Vegas, promoters said today.

The rematch comes more than a decade after the pair’s first meeting in 2015 that generated a record 4.6 million pay-per-view buys and a world-record live gate of $72 million at the MGM Grand Garden Arena.

The rematch will stream on Netflix at no additional cost to its 325+ million subscribers, following Mayweather’s announcement that he is coming out of retirement through a multi-fight partnership with CSI Sports/FIGHT SPORTS, officials said today in a news release.

Mayweather, who turns 49 on Tuesday, hasn’t fought in nine years. The former five-division world champion has still been in the ring regularly throughout his 40s with a series of lucrative exhibition bouts against the likes of online influencer Logan Paul, YouTuber Mikuru Asakura and John Gotti III, the grandson of the infamous mafia boss.

Pacquiao, 47, also recently announced a comeback. He is slated to take on Ruslan Provodnikov in Las Vegas on April 18 in the second fight of his comeback.

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

Netflix Vice President of Sports Gabe Spitzer called the event a “full-circle moment,” having spent time in both fighters’ training camps earlier in his career. Jas Mathur, CEO of Manny Pacquiao Promotions, projected it will become the most-watched boxing event in Netflix Sports history.

The rematch is the latest addition to Netflix’s growing live boxing portfolio, which includes the Jake Paul vs. Mike Tyson event — the most-streamed sporting event in history with 108 million live global viewers, officials said.

It will be the first boxing match at the Sphere, which opened in late 2023.
