Tyson Fury earned around 50 times more for his trilogy bout with Deontay Wilder than Francis Ngannou did for his UFC heavyweight title defence against Ciryl Gane.
Fury and Wilder played out one of the most exciting trilogies in boxing history when they met in 2018, 2020 and 2021, with the Brit winning two of the fights after their first ended in a draw.
And both men were paid considerably more for their involvements in the fights than Ngannou has made in multiple UFC bouts.
The Cameroonian has fought for the title three times in his career, all in pay-per-view main events, twice as challenger and once now as champion.
He was paid $500,000 for his first effort at the belt against Stipe Miocic back at UFC 220 in 2018, which he lost by unanimous decision in Boston.
His next shot at the gold came three years later against Miocic again, where he was paid a reported $580,000 as well as a $50,000 performance bonus, although that base purse figure is not official.
He defeated Miocic in their rematch to claim the belt for the first time, and was paid $600,000 for his first defence against Gane last night.
And while these numbers are nothing to scoff at for most people, they are a sizeable amount less than his boxing counterparts are earning.
Back when he and Miocic first met, Wilder was WBC heavyweight champion, with Fury challenging him 11 months later in an epic Los Angeles fight night.
For that bout, which sold 325,000 pay-per-view units in the United States, Wilder was paid a guaranteed purse of $4million, while Fury made $3million.
That means Fury made five times Ngannou's purse, while Wilder made over six times - but that's only scratching the surface of what the boxers would make from their feud.
By their second and third bouts, Wilder and Fury were both massive stars and their PPV meetings made them guaranteed purses of $5m, which may have risen as high as $30million.
Fury is currently mandated to fight Dillian Whyte in his second world title defence, and part of the method for calculating the massive 80-20 purse split is their declared purses.
Fury is claiming to the WBC to have made $18m for his trilogy with Wilder, which would be a whopping 30 times more than the amount Ngannou made to face Gane.
Would you like to see Francis Ngannou fight Tyson Fury in a boxing match this year? Let us know your thoughts in the comments section below!
Ngannou fought Gane at a sold-out Honda Center in Anaheim, California, a similar size venue to the T-Mobile Arena where Fury fought Wilder in their trilogy last October.
And with pay-per-view prices for the UFC having risen to $75 in the United States this year, the event was only marginally cheaper than the $80 fans paid for Fury and Wilder 3 on the same ESPN PPV platform.
It begs the question where the money is going, with Gane only receiving $500,000, meaning their collective purses are a fraction of what either Fury or Wilder made.
Fury vs Wilder 3 sold a reported 600,000 PPVs in America, so Ngannou vs Gane would have to sell a monumentally lower number for the revenue splits to add up.
Ngannou is currently locked in a contractual stalemate with the promotion, and as it stands could leave as champion if he refuses to fight until December when he becomes a free agent.
