If the Floyd Mayweather–Conor McGregor superfight ever happens, the UFC superstar will have the chance to pull off one of the biggest upsets in sports history—at least according to the oddsmakers.

The Westgate Las Vegas SuperBook released their official odds for the (potential) fight, with Mayweather coming in as a heavy 25-1 favorite.

The odds have McGregor at 11-1 to win over McGregor and are based on the fight being a boxing match:

The fight appeared to be a true possibility early on Valentine’s Day after reports that McGregor was heading to Las Vegas and the Nevada State Athletic Commission confirmed “real discussions” were going on. But then Mayweather poured water on those rumors, posting a message on Instagram saying he was “happily retired."

McGregor of course went back at Mayweather, writing on social media that “I am in Las Vegas. Floyd has retired on my arrival.”

Then early Wednesday morning, Mayweather seemingly backtracked on his “happily retired” comments, writing a message on Instagram hinting to McGregor that a fight still could be possible:

The two may one day end up in the ring. If that happens, then Vegas is pretty confident in their pick.
