How to Bet on Floyd Mayweather vs. Conor McGregor: Guide to Superfight Betting

By Loot, Boxing Handicapper,

The Floyd Mayweather vs. Conor McGregor fight is a Superfight any way you cut it. And when the event is this huge, the betting usually follows suit. You will see a lot of people betting on boxing for the first time. And just like a lot of things where the lingo and numbers are foreign, it's not easy to understand at first. We at Lootmeister know this and have therefore laid out an easy-to-understand blueprint on how to bet on boxing, and more specifically, on the Floyd Mayweather vs. Conor McGregor fight. You will see that it goes way beyond simply betting on who will win the fight. The amount of different Mayweather-McGregor bets you can make is dizzying. We've broken it all down to make it easy to negotiate.

Where to Bet: Naturally, being in Vegas with the plethora of different sportsbooks is an option. But for the millions upon millions of people interested in this fight, the percentage of people who will actually be at the site of fight is very small. And in today's age, the percentage of those who have access to a bookie is also pretty small.

That leaves online boxing betting as the only viable option for a vast majority of those interested in plunking down a few dollars on this fight. It can seem daunting for those who have never done it and understandably so. At the same time, there has been a long enough period since online sports betting became viable to where it can be easily determined which sportsbooks are trustworthy or not.

Here at Lootmeister, we have had offers to deal with just about every book. But only the ones most worthy of our trust have been accepted as affiliates. In other words, if Lootmeister backs a sportsbook, you can rest assured that your information is as safe as it can be, while getting paid and collecting is as easy as 1-2-3. We wouldn't have it any other way. Linking to a book through us will offer afford you some special consideration, as well.


How the Odds Work: When betting boxing in the USA, we will be using an expression of odds known as the money-line. It might seem like mumbo-jumbo at first, but when you get it, you'll wonder why everyone doesn't understand it. This is one of those things that is best explained with an example:

Mayweather vs. McGregor Goes Distance +250
Fight Won't Go Distance -350

In the above bet, you have two choices as to whether the fight will go the distance. You will notice one side of the bet has a plus-sign, while the other has a minus-sign. A plus-sign means that pick is an underdog where you win more than you bet. The fight going the distance is the underdog in this bet at +250, which means you win $250 for every $100 you bet. The fight not going the distance is the favorite at -350, meaning you must bet $350 for every $100 you hope to win. And just so you know, everything revolving around the $100 bet is just to make it easy to understand and visualize. Naturally, you can bet any amount and those odds would just break down to the amount you are wagering.

Here's a handy little guide to understanding money lines:

Plus-Sign (+): Means the pick is an underdog and the number next to the (+) is how much you win for every $100 you bet.

Minus-Sign (-): Means the pick is a favorite and the number next to the (-) is how much you need to bet for every $100 you want to win.

Mayweather vs. McGregor Straight Betting: This is the most-basic form of boxing betting where you simply pick who will win the fight. It's pretty straightforward. One thing to keep in mind is that the decision that is announced in the ring is the binding result. The lone exception could be if a scorecard was quickly detected to be wrong. But any controversy with the scoring that drags on, or if a commission overturns a verdict for any reason, whether it be incorrect officiating, a foul, or a failed drug test, does not help out a losing bet. What is announced in the ring is the verdict that guides how the sportsbook pays off bets. Let's look as of press time for the Mayweather-McGregor odds to win. And keep in mind that this early in the betting in a fight with this much money swirling around it, these odds could all change.

Odds to Win the Mayweather-McGregor Fight
Floyd Mayweather -600
Conor McGregor +450

You see above that Floyd Mayweather is the favorite at -600. Our knowledge of the money lines tells us that means for every $100 we want to win on Mayweather, we need to bet $600. Conor McGregor is +450. He is the underdog, as expressed by the plus-sign. That means for every $100 we bet on McGregor, we win $450 if he wins.

Totals (Over/Under) Betting: The next most-popular form of betting in boxing is a total rounds bet, also known as an over/under. In this bet, who wins the fight is of no consequence. We are merely betting on how long the fight will last. Let's look at the total for Mayweather-McGregor:

Floyd Mayweather vs. Conor McGregor Over/Under
Over 9.5 Rounds (+140)
Under 9.5 Rounds (-160)

Above you see the total is set at 9.5 rounds, making the line in the sand at 1:30 of the 10th round. If you think it will last at least that long, you would bet over. And if you think the fight will end before that, you would bet under. For this wager, the under is favored at -160, meaning you would bet $160 for every $100 you hope to win. The over is the underdog at +140 and you would win $140 for every $100 you bet.

Props: A good way to look at prop bets are that they are smaller results within a bigger result. It's less about who and more about how. For fights this big, the rule of thumb is that if your mind can conceive it, there's a good chance the bet will be offered. You can pick how a fight will end, when it will end, and everything in-between. And for some of the bets, where your position needs to be very specific, the payouts can be pretty big. Let's look at an example of a typical prop bet and then explain the different prop bets for Mayweather vs. McGregor that you will be seeing.

Prop Bet Example:

Mayweather Wins By Decision: +318
Explanation: In this prop, you're picking that Mayweather wins a decision. For this bet to win, he needs to win on the scorecards, whether it be a regular 12-round decision or a technical decision before the 12th round. He is +318. From what we know about how money lines work, the plus-sign indicates an underdog price and this number is how much we win for every $100 we bet. Therefore, a winning $100 bet on this prop would yield $318 in winnings, in addition to getting our $100 bet back. This is how all prop bets will work.

How a Fighter Will Win: Beyond just picking which fighter will win, you can get even more-specific if you have a really good read and pick the manner in which a fighter will be victorious. The two major options, naturally, are by decision or by knockout. And there are a few wrinkles in each. For example, if a fighter is stopped by an accidental head-butt and the fight goes to the scores for a technical decision, that counts as a decision. And a knockout is counted toward this bet with a real KO, a TKO, a disqualification, or a corner or fighter retirement.

How a Fight Will End: Just as how you can pick how a fighter will win, you can pick the way a fight will end, with the main choices being decision or knockout.

Specific Round: For the real daring bettor, you can pick a specific round in which a fighter will win or for when the fight will end. With this being a bet where a lot of accuracy is required, the payout can be quite handsome.

Round Ranges: For those looking to have a little extra backup with a rounds pick, you can pick a range of rounds for when a fight will end or when a fighter will win, with that window usually being 3 rounds, like a KO in rounds 4-6, for example.

Draws: At this level, draws are pretty uncommon. But they do happen and when they do, it can be a big payoff. This has become a more-difficult bet to win in recent years, as a "no-contest" has replaced a technical draw for when a fight ends inside of four completed rounds due to an accidental foul leading to a fight-ending injury. But it can still count toward technical decisions, say if a fight ends after 6 rounds when a fighter can no longer go on after an accidental foul. It's also a good hedge for when you have a lot of money on one fighter to win. You just never know with these judges and betting on a draw is one way to insulate yourself from some of the monkey-business this sport has seen.


Alternate Lines: Naturally, they have odds for who will win the fight and when the fight will end. You can take a more-severe stand and bet on an alternate line. The normal total for this bout is 9.5 rounds. You can make the over/under any number of rounds you want, with the odds adjusting depending on which round you pick. You can also bet on a fighter to win, but he needs to do it within a certain amount of time. A good way to look at these bets are as more-extreme stands on already-existing bets.

Also: If your brain can conceive it, it will likely be offered. We see in events like the Super Bowl where you can bet on such minutia as how long it will take to sing the National Anthem or how many times the announcers will mention the name of a player's girlfriend. It might not get that kooky for the Mayweather vs. McGregor prop bets, but there will be some wild ones. Some of the more-conventional ones you will see in addition to the ones already mentioned are when you determine if a decision will be unanimous, majority or split, both on the fight or for an individual fighter. Or you can take point handicaps on the scorecards for either fighter. You can bet if the fight will end on an even or odd round. A lot of these more-exotic bets will be released closer to fight-night. Good luck!
