Just days away from what will be the biggest money-making fight of all-time, Floyd Mayweather is still favored to beat Manny Pacquiao. While the betting odds vary slightly at different sportsbooks, every oddsmaker has given Mayweather the edge.

Mayweather’s odds have seen a slight increase recently at Bovada.lv, where he is a -225 favorite. The betting website has given Pacquiao +175 odds in the days leading up to the fight.

Pacquiao is also a +175 underdog at Sportsbook.ag, though Mayweather’s odds are -205. The betting odds appear to have settled after there was significant movement when the fight was first made official.

“We don’t expect too much movement from our current line,” Sportsbook.ag Senior Betting consultant Matt James said via vegasinsider.com. “The betting public will be on Manny and the wise guys' money is expected to be on Floyd. Remember, we opened Mayweather -275 back in December, but when the fight was formally and officially announced in February at that time we were at Mayweather -260. All the early money was on Pacquiao to the point that it drove our price down to -200, but since then we have seen some money show on Mayweather and we’re currently dealing -205.”

The majority of bets have been made on Pacquiao, but more overall money is backing Mayweather. As of Sunday, 59 percent of wagers had been placed on Pacquiao at Sportsbook.ag, while 31 percent back Mayweather. But 63 percent of the total money wagered was placed on the favorite.

Betting on Mayweather to win in any fashion might not be worth it to some gamblers, but the odds are more favorable when trying to predict a knockout or decision. The odds for a Mayweather victory by KO, TKO or disqualification are +550 at Bovada.lv. The site gives -135 odds of Mayweather winning by decision.

The last five Mayweather victories have come via decision, and he has just one knockout since his fight with Ricky Hatton was stopped early in 2007. Pacquiao was knocked out by Juan Manuel Marquez in Dec. 2012, but Marquez had achieved four knockouts in his previous eight fights. The loss was the first time Pacquiao had been knocked out in 13 years.

The most unlikely outcome, according to oddsmakers, is a draw. Mayweather has never been involved in a draw, and Pacquiao’s last draw came in 2004. The odds of a draw have been set at +1200 at Bovada.lv and +1000 at Sportsbook.ag.
