Former Ultimate Fighting Championship (UFC) two-division champion Conor McGregor is targeting a spot on the historic UFC White House event scheduled for June 2026 on the South Lawn — which is being billed as “the baddest card of all time,” and McGregor has already positioned himself as a centerpiece of the unprecedented show.
But on today, “The Notorious” briefly floated a far more outlandish idea: a rematch with Floyd Mayweather — this time under mixed martial arts (MMA) rules.
“Fun times @danawhite, @ufc.
@FloydMayweather, when you are ready for that promised MMA bout, I am here.
The White House is nice in the summer I heard.
Just kidding Mike!
Although … I could fight both the same night. Floyd MMA? EASY. 10 seconds.”
As entertaining as the idea may be, it remains firmly in fantasy territory. Mayweather has repeatedly shut down the possibility of competing in MMA, even if a bout with McGregor would once again generate massive attention. The undefeated boxing legend is also reportedly planning an exhibition bout with Mike Tyson next year in Africa.
McGregor and Mayweather previously met in 2017 in one of the biggest boxing events of all time, with Mayweather stopping McGregor via TKO in the 10th round (watch highlights).
McGregor has not competed since suffering a gruesome leg break (see it here) against Dustin Poirier at UFC 264 in 2021.
