Floyd Mayweather has opened as a -220 favorite over Manny Pacquiao at the Westgate Las Vegas SuperBook — if the fight happens by the end of next year.
Mayweather said in an Instagram video Saturday morning that a rematch between the two will take place this year. Pacquiao then followed up with a tweet that read “50-1 #NoExcuses” with a video of the two together.
Mayweather is 50-0 in his career and last fought against UFC star Conor McGregor in August of 2017.
The fight must take place before the end of 2019 for action.
A bettor would have to lay $22 to win $10 if betting on Mayweather. Anyone wagering on Pacquiao would win $18 on a $10 bet.
Mayweather and Pacquiao fought in May of 2015, with Money winning by unanimous decision. Two judges scored it 116–112, the other 118-110.
While sports bettors often side with favorites, books made a killing on Mayweather in their last fight because of one-sided action on the underdog. He closed around -200.
Pacquiao last fought in July, defeating Lucas Matthysse by TKO in the seventh round to win the WBA welterweight title.
