'McGregor makes a lot from fighting. A study by OLBG found that he makes over $8m for every minute in the octagon'
In 2020, the now 33-year-old fighter told ESPN he believed he would be a billionaire by the time he's 35.
However, he looks set to beat his own prediction by at least a year as it looks like he will break into the billionaire bracket as he turns 34 in July.
Andrew Petcash, a sports entrepreneur and former Division 1 basketball player at Boston University, detailed how the Notorious is about to turn the major financial corner in a series of tweets.
A former athlete himself, Petcash created the Petcash Post, a newsletter that “breaks down the business of athletes & sports" which is “read daily by athletes, coaches, sports professionals and fans”.
In the first tweet Petcash declares: “Conor McGregor will be a billionaire this year, (earning) $235m from fighting and a $600m deal off the ring.
He adds: “McGregor makes a lot from fighting. A study by OLBG found that he makes over $8m for every minute in the octagon.
"Billed as ‘The Money Fight’, the Dubliner took on Floyd Mayweather in what was the second most watched fight of all-time,” Petcash reports. “The duo pocketed $400M combined.
“Conor also known as ‘Notorious’ is a huge asset to advertisers," Petcash states and then lists his endorsements that include Reebok, DraftKings, Burger King, Beats by Dre, Wynn Resorts, Roots of Fight, MonsterEnergy and EA (Electronic Arts).
“McGregor made $158m last year - it's the most ever by an athlete,” he adds.
“McGregor invested in his own fitness program, FAST, a program (that) helps users get into fighting shape. Last year it did $5m in revenue.
“August McGregor, his fashion and lifestyle line, created alongside A-list tailor David Heil makes luxury suits for the likes of Elon Musk. Around $50m/year in profits is created by this menswear brand,” Petcash tweets, adding, “a huge acquisition is on the horizon.
“The Mac Life, Conor's media house has 1.2m subscribers on YouTube. The Mac Life primarily covers MMA, sports, lifestyle and fitness (and) early every video gets six figure views bringing in $1000's of ad revenue.”
He also refers Proper No 12, Conor’s whiskey brand that had $1bn in sales in its first year of launch.
“In April 2021, McGregor sold his majority stake to Proximo Spirits for $600m,” Petcash adds. “He is estimated to have made a whopping $150m from this deal.”
As well as his big earnings, Petcash highlights McGregor's philanthropy.
“Conor may be notorious in the ring, but he's generous in the community, adding: “Donated $1m for families of deceased first responders. Built houses for the homeless in Dublin. Donated $1.4m in PPE kits to healthcare workers in Ireland.
“Conor McGregor, 'The Notorious One', excels equally at business and sport,” Petcash sums up. “In his words, fighting is his 'third income'.
“With his smart business moves, he is all set to achieve his personal goal of becoming a billionaire by the time he is 35.”
McGregor is not shy about splashing his cash.
Just last week he took ownership of his new 63-foot-long Lamborghini Technomar, nicknamed the “supercar of the sea” after seven months of waiting for the vessel to be ready.
Estimated to cost in the region of €3 million, McGregor previously referred to 4000-horsepowered, dual engine, twin turbo, “rocket ship” as the best purchase he has ever made.
“I am honoured to secure the Number 12 edition of just 63 to be made,” he revealed on Instagram last year. “1963 being the year Lamborghini first began, and 12 being, well you know Twelve
When later asked by MMA journalist, Aaron Bronsteter, what was the best purchase he ever made, McGregor said: “I would say my Lamborghini yacht.
“It's some vessel so I'm really excited to get into it and rally it around. I look forward to setting records on it also.
McGregor also has a collection cars including a luxury Rolls Royce worth more than €435,000 that was seen most recently in Temple Bar.
The Notorious rocked up outside The Porterhouse and Roberta’s on Parliament Street and shared a photo of his black Rolls Royce Phantom VIII on the cobblestoned paths.
A grey Range Rover Sport worth around €87,400 can also be spotted in the photo parked behind the Rolls Royce.
McGregor, of course, also famously purchased the Black Forge Inn in Dublin 12 for €2m in 2020 and later spent a further €1m renovating the pub
He also recently secured planning permission with 10 planning conditions attached by the council for the scheme, which will see it expanded at the rear of the venue.
In May of last year, it was reported how a record four athletes had each earned $100 million or more in the previous 12 months.
According to data from Forbes, MMA star McGregor topped the list of the world's 10 highest-earning athletes, having made $180 million in 2020.
“This is the 32-year-old's first time in the No. 1 slot -- and it isn't just because of his fighting earnings," it was reported.
McGregor has also often appeared in numerous social media posts with his entourage or partner Dee where he appears in designer clothes and sports exclusive watches and other trappings of wealth
