Conor McGregor, the former two-division UFC champion, is set to end a five-year hiatus tonight when he faces Max Holloway at UFC 329 in Las Vegas. The 37-year-old Irishman, already one of the wealthiest fighters in combat sports, is expected to add significantly to his estimated net worth of $200 million (£149.3m), according to Celebrity Net Worth.
McGregor's UFC Comeback and Earnings
McGregor has not fought since breaking his leg in a first-round defeat to Dustin Poirier in 2021. He was due to return two years ago against Michael Chandler but pulled out due to injury. Tonight's bout against Holloway marks their second encounter, 13 years after McGregor won their first fight by decision in Boston.
The UFC has moved away from its pay-per-view model after signing a $7.7 billion media rights deal with Paramount+ in January. Instead, fighters at UFC 329 receive a guaranteed flat fee. McGregor, who features in eight of the top 10 highest-selling PPVs in UFC history, earned roughly $33 million (£24.6m) for his last fight against Poirier and $22 million (£16.4m) for their rematch six months earlier.
His most lucrative payday came in 2017 when he boxed Floyd Mayweather, earning around $100 million (£74.6m) despite a late stoppage defeat. In total, his UFC earnings are estimated at over $235 million (£175.4m). Official purses from the Nevada State Athletic Commission show he made a guaranteed $3 million (£2.2m) for his fight against Khabib Nurmagomedov, the highest-selling PPV in UFC history.
Endorsements and Business Ventures
McGregor has endorsed more than 20 major brands, including Monster Energy, Beats by Dre, Burger King, Reebok, DraftKings, and Bud Light. He also owns several pubs in Dublin, most notably The Black Forge Inn, which he purchased for $2.2 million (£1.7m) in 2019 and spent an additional £868,000 transforming into a gastro pub.
His most successful business venture is Proper No. Twelve Irish Whiskey, launched in 2018. In 2021, McGregor and two other investors sold their stakes for $600 million (£503m). He also launched Forged Stout to rival Guinness, which is widely advertised at major sporting events. Additionally, he created a fitness app five years ago and co-founded August-McGregor, a clothing line selling suits and casualwear.
In 2024, McGregor became a part-owner of the Bare Knuckle Fighting Championship (BKFC), expanding his influence in combat sports.
McGregor's Manchester United Dream
McGregor has repeatedly expressed interest in buying Manchester United. In 2021, after former executive vice-chairman Ed Woodward stepped down amid the Super League controversy, McGregor posted on X (formerly Twitter): "Hey guys. I'm thinking about buying Manchester United! What do you think?" He later added: "I am certainly interested in acquiring a sports team at some stage! Both Celtic and Man United are teams I like for sure."
However, his proposition was largely tongue-in-cheek, as he lacked the financial capability to purchase the club alone. Talks of a takeover resurfaced in October 2025 after Saudi boxing promoter Turki Alalshikh suggested United had reached an "advanced stage" of negotiations with new investors, though he later clarified he was not involved. Sir Jim Ratcliffe had already bought a nearly 30% stake in the club in 2023 via his company Ineos.
McGregor's net worth of $200 million falls far short of United's valuation, which exceeds $6 billion. Still, his business acumen and growing wealth keep the dream alive.
