Floyd Mayweather and Manny Pacquiao Agree September Rematch at Sphere in Las Vegas — Netflix to Stream Live

floyd mayweather and Manny Pacquiao have agreed to a professional rematch scheduled for Saturday, 19 September at Sphere in Las Vegas, billed as the first professional boxing match to be staged at that venue and set to be streamed live on Netflix. The announcement revives one of boxing's biggest rivalries and raises immediate questions about rounds, weight class and the fighters' motivations.

Floyd Mayweather's comeback, record and recent activity

Former world champion Floyd Mayweather has announced he will come out of retirement for a fourth time. This will be his first professional bout since beating Conor McGregor by 10th-round technical knockout in 2017. Mayweather has an unbeaten professional record of 50 wins, with 27 of those by knockout. He has participated in a string of exhibition bouts since 2017 and is scheduled to face Mike Tyson this year.

Mayweather has made public claims that his events will generate the biggest gates, the largest global broadcast audiences and the most revenue for each event. It is also noted that Mayweather will turn 49 on Tuesday; elsewhere in the available material it is stated that he will be 49 when the fight takes place. The differing age references are unclear in the provided context.

Manny Pacquiao's return, record and motivations

Manny Pacquiao retired from professional boxing in 2021 to focus on his political career and returned to the ring last July to fight WBC welterweight champion Mario Barrios. That fight ended in a draw, allowing Barrios to retain his title. Pacquiao is credited with 62 wins from 73 bouts and is described as a winner of 12 world titles across eight weight classes.

Pacquiao has framed the rematch as something the fans deserve, saying the two gave the world the biggest fight in boxing history and expressing a desire for Mayweather to live with the one loss on his professional record and remember who handed it to him. He has dedicated the fight to fellow Filipinos and to bringing glory to the Philippines. In October he had said the pair were close to agreeing a rematch but that it depended on their ability to understand each other.

Floyd Mayweather and the timeline of post-2015 fights and exhibitions

• Beats Andre Berto by unanimous decision in September 2015 to move to 49-0, then retired shortly after.
• Returned for a professional, sanctioned crossover bout against Conor McGregor, which Mayweather won by TKO in the 10th round, securing a 50-0 professional record.
• Exhibition vs. Tenshin Nasukawa in December 2018: Nasukawa was flattened three times and stopped inside one round.
• Exhibition vs. Logan Paul in June 2021 at Hard Rock Stadium in Miami, Florida: the pair went the full eight rounds with no winner declared.
• Exhibition vs. Don Moore in May 2022 in the United Arab Emirates: the bout went eight rounds, Mayweather dominated exchanges and scored a knock-down.

Details confirmed — venue, date, broadcast and open questions

The rematch will take place on Saturday, 19 September at Sphere in Las Vegas and will be streamed live on Netflix. It is described as the first professional boxing match ever staged at Sphere. It is not yet known over how many rounds the rematch will be contested or at what weight class. It is also noted that, unlike title fights, this rematch will feature no belts.

The fighters first met in 2015 in a fight billed as the 'Fight of the Century' and said to remain the richest fight in boxing history; Mayweather won that encounter by a wide unanimous decision in Las Vegas. Observers in the available material characterise the 2015 encounter as a tame affair with both fighters past their peaks and say the September bout could be of even lower quality.

Financial expectations, streaming context and stakes

Predictions in the available coverage indicate the rematch will be lucrative: it is expected to earn the pair tens of millions of dollars. Pacquiao is framed as a national hero in the Philippines while Mayweather is described as having forged a lucrative career and a reputation for playing the villain.

Netflix's live sports push is highlighted in the context of the broadcast: a previous Netflix stream of Jake Paul versus Mike Tyson in 2024 attracted 108 million live global viewers and is described as the most-streamed sporting event in history. Netflix has also carried NFL games on Christmas Day and recently provided live coverage of a climber scaling a Taipei skyscraper.

What remains unresolved and what to watch next

Key operational details remain unresolved: the rounds and weight class for the rematch are not yet known. The fighters' exact ages at fight time are presented inconsistently in the available material and are unclear in the provided context. The promotional build and final financial terms are not specified here. Observers should watch for official confirmations on rounds, weight, undercard, and promotional logistics in the coming weeks.
