Mairon Santos

Mairon Santos is a Brazilian mixed martial artist competing in the UFC Featherweight division. Known for his relentless pressure and elite Brazilian Jiu-Jitsu, Santos has quickly become a rising contender since entering the promotion in 2023. With a 7-2 UFC record and multiple performance bonuses, he is considered a potential future title challenger. Santos trains between Nova União in Rio de Janeiro and American Top Team in Florida, splitting his time between the two camps. As of 2026, he is ranked #14 in the division and preparing for a top-10 matchup at UFC 310.[edit]

Santos grew up in a working-class neighborhood of Rio de Janeiro, where street violence was a daily reality. At age 10, a local BJJ coach took him under his wing, giving him a purpose and a path away from trouble. He threw himself into jiu-jitsu, winning state-level titles as a teenager and earning his black belt by 22.

To support his training, Santos worked as a bouncer at a Rio nightclub. He began Muay Thai and boxing at 17, rounding out his striking. In 2019, he won the Brazilian National Jiu-Jitsu Championship as a brown belt, catching the eye of MMA scouts. He made his professional debut in 2020 on the regional circuit, winning by submission. Over the next year, he went 4-0 with all finishes, earning a spot on Dana White's Contender Series in 2022.[edit]

Santos competed on Season 6 of Dana White's Contender Series in 2022, winning a unanimous decision but initially not receiving a contract. He signed with the UFC later that year and made his promotional debut at UFC 288 in May 2023, taking a split decision. He finished 2023 with a 2-1 record.

In 2024, Santos knocked out both his opponents, earning a Performance of the Night bonus for a first-round KO. He headlined his first UFC Fight Night in March 2025, submitting a top-15 opponent and breaking into the official rankings at #14. As of early 2026, he is scheduled to face #9-ranked Josh Emmett at UFC 310 in June.[edit]

Santos is known for his aggressive, pressure-based fighting style, combining elite BJJ with developing striking. The media portrays him as a humble, hungry fighter with a bright future, often calling him "the next big thing" in Brazilian MMA. His fans, who call themselves "Team Buzzsaw" online, appreciate his relentless pace and submission finishes. On social media, Santos posts training clips and motivational quotes, engaging mostly in Portuguese.[edit]

Mairon Santos stands as a compelling figure in the modern MMA landscape, though iFANN has not yet gathered sufficient data to assign him a specific global fame ranking. While he commands a dedicated following among combat sports enthusiasts, his name has not yet crossed into the tier of universal recognition where precise ordinal placements are calculated by our algorithms. His audience, often referred to online as "Team Buzzsaw," demonstrates intense loyalty through their appreciation of his relentless pace and submission finishes, yet this group lacks a formal, documented organizational structure or unique rituals that define larger celebrity movements. Unlike veterans with decades of folklore, Santos is currently navigating the transition from rising prospect to established contender, a phase where fan engagement remains focused on fight outcomes rather than cultural mythology. The absence of a ranked position in our current database reflects this transitional status; while media outlets frequently label him a "fan favorite" and highlight his upcoming challenges against top-tier opposition like Nathaniel Wood, these descriptors signal marketability rather than a quantified level of worldwide fame. As his career progresses toward potential title shots and high-profile events like UFC Paris, his profile will undoubtedly shift, but for now, the lack of a formal fandom name or organized campaigns underscores that he is still building the historical weight required for a definitive ranking.[edit]

Before stepping into the octagon, Mairon Santos worked as a bouncer at a nightclub in Rio de Janeiro, a job that honed the physical resilience he brings to his striking today. He holds a third-degree black belt in Brazilian Jiu-Jitsu, a rank he achieved at just 22 years old, and splits his training time between Nova União in Rio and American Top Team in Florida. An avid surfer, he often takes his workouts to the ocean waves when based in Brazil, and his passion extends to the football pitch as a devoted Flamengo supporter. In 2024, UFC commentator Jon Anik bestowed upon him the nickname "The Brazilian Buzzsaw" following a stunning first-round knockout that signaled his arrival on the world stage. Fans also recall his victory in The Ultimate Fighter Season 32, which cemented his status as a top prospect before his professional record climbed to 18-1-0. A notable chapter in his recent narrative involves a weight miss incident in December 2025 prior to UFC 323, an event he publicly addressed with humility, vowing to correct the mistake and turning a potential setback into a story of accountability. These moments combine with his aggressive fighting style to build a legend of a fighter who is constantly evolving under pressure.[edit]

Santos keeps his family life private. He has not publicly named his parents or siblings, though he has mentioned in interviews that he fights to support his family back in Brazil. He has no reported children and is not married. His coach at Nova União, Master Ricardo, is described as a father figure.[edit]

Santos trains under Master Ricardo at Nova União and frequently spars with former champion Charles Oliveira and fellow contender Diego Lopes. He is managed by Tiago "The Hawk" Silva of Titan Management Group.[edit]

Santos is private about his romantic life. He was in a relationship with a woman from his hometown in Rio de Janeiro from 2019 to 2021, ending amicably before his move to the United States. Since then, he has not been publicly linked to anyone. As of 2026, Santos is single and has stated in interviews that he is fully focused on his fighting career.[edit]

iFANN currently estimates Mairon Santos's net worth at $875,000 as of 2026. This financial standing is built primarily on his earnings from UFC fight purses and performance bonuses. His base pay per bout has fluctuated between $30,000 and $50,000, with win bonuses effectively doubling those figures. His headlining appearance in 2025 likely generated over $100,000 in total compensation, bolstered further by a $50,000 Performance of the Night bonus awarded in 2024. Beyond the cage, Santos maintains smaller sponsorship agreements with local Brazilian supplement brands and a regional fight gear company. Despite his rapid rise in the rankings, there are no public records of real estate holdings or reported external investments, keeping his wealth closely tied to his active fighting career.[edit]

Santos has won a UFC Performance of the Night bonus in 2024 for a first-round knockout. He also won gold medals at the Brazilian National Jiu-Jitsu Championship in the purple belt (2017) and brown belt (2019) divisions.[edit]
