Floyd Mayweather vs. Conor McGregor Odds Update: Betting Lines, Props, Analysis

The megafight between two-division UFC champion Conor McGregor and unbeaten welterweight boxing champ Floyd Mayweather Jr. is now less than a month away, and bettors continue to support the underdog Irishman despite this being his first professional boxing match.

Sportsbooks monitored by OddsShark show McGregor as a consensus +400 underdog (bet $100 to win $400) with Mayweather still sitting as a large -600 favorite (bet $600 to win $100). The big question is, how low will the betting line go?

It is safe to say the public has taken more interest in this matchup than any other in boxing history. The intrigue behind McGregor's strategy and inexperience inside the boxing ring combined with Mayweather's age and long layoff as the 40-year-old attempts to pick up win No. 50 have taken the world by storm over the past month.

Mayweather has not fought since earning a unanimous-decision victory against Andre Berto to improve to 49-0 nearly two years ago on September 12, 2015.

The hype behind this fight has been unlike anything anyone has ever seen, with many boxing purists believing it is nothing more than a publicity stunt. Regardless, there is a lot of money to be made by the two fighters who will go toe-to-toe at T-Mobile Arena in Las Vegas on August 26.

Bettors think they will be able to capitalize as well, no matter who they are supporting. The sportsbooks have them covered with a number of props.

For example, McGregor backers will not find much value on the KO/TKO/DQ prop right now at +500 since that is likely his only path to victory. The same cannot be said for Mayweather though, as the same prop for him has a price of -140, with a decision in his favor paying out much better at +200. McGregor winning by decision is +1000.

If you are looking for round props, betting either fighter to win in the 12th is worth +1800 compared to the fight going the distance (+160) and a draw (+3300). McGregor guaranteed a knockout within the first four rounds, and you can get +700 if you believe he will back that up. By comparison, Mayweather to win in the first four rounds is +400.
