Conor McGregor, seen entering the UFC Octagon, has been a favorite when looking at Conor McGregor odds history.

Conor McGregor Odds: Career UFC Betting Odds History

Conor McGregor has taken the combat sports world by storm since entering the UFC in April 2013. His rare combination of unparalleled bravado and unique striking ability has made him the most polarizing UFC fighter of all time. What sets him apart from other trash-talkers in the sport is his ability to back up his words in impressive fashion, as he’s recorded eight TKO/KO finishes in his 13 UFC fights.

Going back to his time outside the UFC, the 32-year-old Irishman has won 22 of his 27 pro fights. He finished 19 of those fights by TKO/KO, one by submission and two by decision.

Conor McGregor’s Odds

From the start of Conor McGregor’s career, he had a lot of shine. Odds of -155 made him a betting favorite in his UFC debut vs Marcus Brimage in 2013 and he has closed as a favorite in all but two fights since. McGregor’s high was -950 vs Dennis Siver at the start of 2015. Meanwhile, against hard-nosed fighter and cardio king Nate Diaz in a welterweight bout at UFC 202, McGregor’s fight odds were -155.

McGregor was an underdog for the first time in his UFC career vs Jose Aldo at UFC 194, closing at -105 before knocking out the Brazilian in 13 seconds.

The line for McGregor’s last fight against Dustin Poirier closed with McGregor as a -315 favorite. The Irishman absorbed several leg kicks that left him in a boat in the ocean with no oars as Poirier swarmed him with a flurry of shots, eventually putting McGregor down for a knockout loss.

McGregor vs Floyd Mayweather

McGregor’s meteoric rise earned him a major payday and a dance with Floyd “Money” Mayweather Jr., arguably the greatest boxer of all time. Understandably, Notorious was an underdog against the multi-division champion, then 49-0, but not by as much as you might have expected as he ended up closing as just a +265 underdog.

Unfortunately for McGregor backers in that pro boxing event, Mayweather scored a 10th-round TKO for the win, but McGregor’s $100-million payday was a win as well.

It wasn’t a completely one-sided affair, though, as many, myself included, believe that McGregor won several rounds before Mayweather kicked it into another gear. Conor says that he learned Floyd’s tendencies and that he would beat him in a rematch – oddsmakers don’t agree as McGregor is an early +600 underdog.

McGregor vs Khabib Nurmagomedov

Following the May-Mac event, the Irishman returned to the Octagon in a highly anticipated bout for the UFC lightweight belt against Khabib “The Eagle” Nurmagomedov. There was really bad blood between these athletes that spilled over when McGregor attacked Nurmagomedov’s bus with a dolly ahead of the Eagle’s title fight at UFC 223 in Brooklyn in April 2018. 

Once McGregor sorted out his legal issues from the bus incident, the fight was on at UFC 229 in October 2018. And for the second time in his MMA career, Conor was an underdog (+130). Nurmagomedov won that bout via fourth-round submission.

2021: The Season of Conor McGregor?

Notorious announced in an interview in late 2019 that he would be returning to the Octagon in 2020 for a season that would consist of at least three fights, with his sights set ultimately on a rematch with Nurmagomedov. His first fight came at UFC 246 in January as he stood across the cage from fan favorite Donald “Cowboy” Cerrone.

While the COVID-19 pandemic halted McGregor’s season, perhaps his plans have simply been pushed back a year with one fight already in the books, a loss to Dustin Poirier on January 24. The two look to be linking up again for a trilogy bout in the summer and a third McGregor fight could potentially take place later in the year.

Here’s a list of McGregor’s career UFC odds along with three fights from his pre-UFC days:
