Betting $100 on Conor McGregor? Floyd Mayweather? With current odds, it's a $487.50 difference

Placing a bet on the upcoming boxing match between UFC lightweight champion Conor McGregor and undefeated boxer Floyd Mayweather?

Prepare for two very different potential payouts.

As officials announced on Wednesday – after months of speculation and negotiations – McGregor (21-3 MMA, 9-1 UFC) and Mayweather (49-0 boxing) are finally scheduled to fight in a pay-per-view headliner. The 12-round, 154-pound boxing bout takes place Aug. 26 at T-Mobile Arena in Las Vegas.

Betting lines for the fight have been out for months – even when the fight seemed more like fantasy matchmaking than actually possible. However, the current odds consensus favors Mayweather (-800) over underdog McGregor (+500). The means a bettor would need to wager $800 on Mayweather to net $100 in profit from a winning bet. Meanwhile, a bet on McGregor would come with a 5-1 payoff.

So:

• A winning $100 bet on Mayweather (-800) would result in a profit of $12.50
• A winning $100 bet on McGregor (+500) would result in a profit of $500

As lopsided as the odds are now (and they may vary from sports book to sports book) – that’s a $487.50 difference in potential payouts, after all – they were even wider when the lines first opened back in November. Mayweather initially was a -2250 favorite (with a $4.44 payoff on a $100 bet) over +950 favorite McGregor ($950).

Early betting has favored McGregor, who’s garnered more than 90 percent of wagers, according to SportsInsights.com, “which isn’t all that surprising considering the reluctance of recreational bettors to lay moneyline odds in this range.”
