They’ve become household names because of their abilities in the Octagon, and as their fame grows, so do their bank balances. These UFC fighters have dominated the mixed martial arts game and aren’t shy to spend their hard-earned cash. Here are the richest UFC fighters of all time, according to multiple sources, and how they spend their money. Why Cristiano Ronaldo can’t sell his Trump Tower flat B.J. Penn – US$22 million B.J. Penn was the first non-Brazilian winner of the World Jiu-Jitsu Championship, taking the black belt division in 2000. This opened the door to UFC, where he would became champion of both the lightweight and welterweight divisions – the second of seven fighters to win multiple titles – and was hailed by UFC president Dana White for bringing the lower weight divisions into the spotlight. He has a net worth of US$22 million and, according to Ultimate Fighting Network, most of his wealth is from fight pay during his eight-year UFC run. He also had endorsement deals with Reebok and Last Shot, and runs his own gym and an MMA media distribution website. Brock Lesnar – US$25 million Whether fans know him from UFC or WWE, Brock Lesnar has clearly made a fortune from his fight power. According to Sportskeeda , Lesnar brought the UFC some of its highest selling pay-per-view events. His pay for his UFC 200 fight against Mark Hunt alone was reportedly US$2.5 million. The publication also reports he owns a collection of luxury cars and lives in a US$2.1 million home in Canada. According to Talk Sport, Lesnar was WWE’s biggest earner in 2020 and his earnings are now based on a flat rate, not the pay-per-view buys like other fighters. LeBron James’ epic luxury car collection George St-Pierre – US$30 million He retired from the UFC in 2013 but reappeared in 2017 to claim the middleweight championship. After becoming the fourth multi-division champion in UFC, the mighty GSP retired again in 2020. The Canadian fighter has been inducted into the UFC Hall of Fame and UFC president Dana White once said the fighter earned close to US$5 million at UFC 158. He has had endorsement deals with big brands likes Coca-Cola and Under Armour. Khabib Nurmagomedov – US$40 million He made his UFC debut in 2012 and is estimated to have a net worth of around US$40 million. Sportskeeda reports he started off earning just US$32,000 per appearance but as his reputation and wins grew, his purse increased. After beating Conor McGregor back in 2018 , Nurmagomedov took home US$1.5 million, and the fighter has scored endorsement deals with Reebok and Toyota. According to Ultimate Fighting Network, the Russian star is the co-founder of martial arts centre Eagles MMA and gets paid to give masterclasses and lectures.
