Ciryl Gane, nicknamed “Bon Gamin,” is a French mixed martial artist who competes in the UFC heavyweight division. Born on April 12, 1990, in La Roche-sur-Yon, he is a two-time UFC interim heavyweight champion and one of the sport’s most technically regarded heavyweight strikers, according to Wikipedia’s overview of his career. HMW estimates retained assets from disclosed UFC purses, confirmed performance bonuses and reported endorsement deals. It does not infer a figure from popularity or social reach, and it treats his early, lower-purse fights separately from the seven-figure paydays of his title runs rather than assuming continuous peak earnings.

Gane grew up playing football and basketball and did not begin training in combat sports until his early twenties, after a friend introduced him to a Muay Thai gym while he was working a study program in furniture sales in Paris. He turned professional in Muay Thai in 2016 and compiled a 14-0 record, winning the AFMT National Title at +91kg, a run detailed in EssentiallySports’ account of his career earnings. He made his professional MMA debut in 2018 with the Canadian promotion TKO, winning the vacant heavyweight title by submission and defending it twice before signing with the UFC in 2019. Income from this period is valued conservatively, since regional promotion purses are far smaller than his later UFC paydays.

Gane made his UFC debut on August 10, 2019, and built a 10-0 unbeaten run through the heavyweight division. That streak culminated on August 7, 2021, at UFC 265, where he stopped Derrick Lewis in the third round to win the interim heavyweight championship and earned a Performance of the Night bonus, a result confirmed in Wikipedia’s career summary linked above. The win vaulted him into title-unification contention and marked the point at which his purses moved into six-figure and eventually seven-figure territory.

Gane has fought for the undisputed or interim UFC heavyweight title four times. He lost a unification bout to Francis Ngannou at UFC 270 in January 2022 after leading on the scorecards through two rounds, then lost to Jon Jones by first-round submission at UFC 285 in March 2023 for the title Ngannou had vacated. On June 14, 2026, he won the interim heavyweight championship a second time, stopping former two-division champion Alex Pereira in the second round at UFC Freedom 250, a result covered by CBS Sports’ report on the Pereira fight. That win, which earned him a $425,000 Performance bonus, set up a rematch with undisputed champion Tom Aspinall. Only documented purses and bonuses tied to these results are counted in this estimate.

Gane built a reputation early in his UFC run as an unusually fluid mover for a heavyweight, and his run to the interim title made him one of the sport’s most closely followed contenders outside the United States. His profile crossed further into the mainstream when he headlined the co-main event of UFC Freedom 250, held on the South Lawn of the White House, a booking reported by UFC.com’s coverage of the event. He has also appeared on screen, including a role in the 2025 Netflix release “KO” and a cameo in “Den of Thieves 2: Pantera.” Media reach and viral moments are treated here as brand equity, not booked as a direct dollar value.

Gane signed a two-year image and sponsorship contract with combat sports brand Venum in late 2021, formalizing a relationship the fighter had worn into his interim title win, according to Sport Buzz Business’ report on the Venum deal. He also carries UFC-arranged partnerships with Monster Energy, along with individual endorsement deals reported for G-Shock watches, lifestyle brand DFNS, Crypto.com and MYPROTEIN France, as detailed in EssentiallySports’ reporting linked above. These arrangements are valued using reported deal terms where available and treated as modest supplementary income rather than a primary earnings source, since fight purses remain his dominant income stream.

Gane has not disclosed ownership of a gym, apparel line or other operating company with published accounts. He trains and is closely associated with MMA Factory in Paris, but public reporting describes this as a coaching relationship with Fernand Lopez rather than an ownership stake. His income outside fighting centers on appearance-linked endorsement deals rather than an independent business he controls, and HMW does not assign enterprise value to training partnerships without financial disclosure.

Gane lives in Nogent-sur-Marne, just east of Paris, in a home reported to include a large garden and swimming pool, according to Analyse Économique’s profile of his fortune and assets, which also credits Gane with a cautious, long-term approach to managing his earnings. The same reporting identifies a Mercedes-Benz G-Class and a Yamaha Ténéré 700 motorcycle as his documented vehicles. No purchase price or square footage for the property has been publicly disclosed, so this estimate applies a conservative valuation to the home and vehicles rather than treating them as confirmed high-value line items.
