The UFC lightweight champion can now boast to be sharing the same list with legendary boxers such as Mike Tyson, Oscar De La Hoya, Manny Pacquiao, Evander Holyfield and, of course, Mayweather himself.
With speculation mounting regarding his fighting future and whether or not he will ever return to the Octagon, McGregor said he is putting his boxing career on hold for a bit and want an MMA fight next.
Floyd, of course, is coming off his mega-fight with UFC superstar Conor McGregor.
McGregor hasn't competed in the UFC since 2016 when he won the lightweight championship with a second round TKO against Eddie Alvarez.
"A real fight", McGregor said while signing autographs. However the UFC has been under new ownership for months. What's a real fight?
In the 10th, Mayweather moved in for kill pinning a visibly tired McGregor against the ropes and landing a flurry of punches when the referee stepped in to stop the fight.
But Friday night, he gave perhaps his most definitive clue yet for his next venture: You can expect him back in the UFC's octagon - not in a boxing ring.
According to a new report from Brian Campbell of CBS Sports, Showtime Sports confirmed that there were 4.3 million pay-per-views for the fight.
The blockbuster event took in more than over $600m in revenue from ticket sales, sponsorship and global distribution.
Pacquiao's promoter, Bob Arum of Top Rank, has very little interest in the fight but he's willing to make it happen if that's the opponent that Manny requests.
He said: "They just called me not too long ago and asked me to come back".
