Conor McGregor teases unfinished Floyd Mayweather business amid his hyped UFC comeback match

Conor McGregor says he is still open to a rematch with Floyd Mayweather, nine years after their 2017 boxing crossover became one of combat sports' biggest paydays. Speaking ahead of his UFC return, McGregor confirmed conversations with Mayweather's camp remain ongoing, even with his full attention on Saturday's main event against Max Holloway.The comments land days before McGregor headlines UFC 329 at T-Mobile Arena, the same venue where Mayweather beat him in 2017. It marks McGregor's first octagon appearance since breaking his leg against Dustin Poirier in July 2021, and a win over Holloway would reopen the door to boxing's most lucrative crossover fight.

Asked directly about a second Mayweather fight, McGregor didn't hesitate. "I'm open for it," he said, adding that talks with Mayweather's side have never really stopped.

The original bout carried the nickname "The Money Fight" for good reason: both men walked away with hundreds of millions of dollars from a pay-per-view audience that dwarfed most traditional boxing cards. A sequel wouldn't need to match that number to still be enormous business for both sides.

Conor McGregor vs Floyd Mayweather: What happened in the match

McGregor, a career MMA fighter stepping into a boxing ring for the first time at that level, actually built early momentum against the sport's pound-for-pound great.

He landed clean shots and pushed the pace through the opening rounds. But Mayweather's conditioning and boxing IQ took over as McGregor's gas tank emptied, and the fight ended in the 10th round on a TKO that pushed Mayweather's record to 50-0.

McGregor has also spoken about how the fallout from that 2017 payday affected his personal life, pointing to the whiskey business he launched afterward and a period of heavier drinking.

"I was trapped and caught, and it is what it is," he said, framing the stretch as a lesson he's since moved past.

That period also included a civil case brought by Nikita Hand, who alleged McGregor assaulted her in a Dublin hotel in December 2018. A jury found him liable in November 2024 and ordered him to pay nearly £206,000 in damages. McGregor has denied wrongdoing throughout. Ireland's Court of Appeal rejected his appeal in July 2025, and the Supreme Court declined to hear a further appeal in December 2025, leaving the verdict in place.McGregor has framed Saturday as the first step in a broader run that includes chasing a third UFC weight class title. Whether any of that includes a second Mayweather fight depends first on what happens at T-Mobile Arena, where a 37-year-old five years removed from competition finds out whether the layoff has caught up with him. "The excitement's going to be off the charts on Saturday night," he said.
