Jermell DeAvante Charlo is an American professional boxer and former undisputed world super welterweight champion, born May 19, 1990, in Lafayette, Louisiana, and raised in Houston, Texas. He is the identical twin brother of fellow boxer Jermall Charlo, younger by one minute, and the two grew up training together after their father, a former amateur boxer, introduced them to the sport as children. Both brothers graduated from Alief Hastings High School in Houston. Jermell fights under the nickname “Iron Man” and is widely regarded as one of the best 154-pound fighters of his generation, a career documented in detail on Wikipedia.

The Charlo twins are unique even by professional boxing standards: they became the only siblings in the sport’s history to hold reigning world titles in the same weight class at the same time, Jermell at super welterweight and Jermall at middleweight. That shared story has shaped much of how Jermell has been covered by the boxing press throughout his career, with the brothers frequently training together and appearing on the same fight cards.

Charlo built a standout amateur résumé, winning a bronze medal at the 2005 Junior Olympics at age fifteen and finishing his unpaid career with a record of 56 wins and 8 losses. He turned professional in 2007 at just 17 years old, working his way up through regional cards while training under coach Ronnie Shields in Houston. His profile and full fight-by-fight record are tracked by ESPN’s boxing database.

Two wins in particular signaled his readiness for world-level competition. In January 2014 he outclassed veteran Gabriel Rosado over ten rounds, landing roughly half his punches to Rosado’s 18 percent, and in March 2015 he edged past the durable Vanes Martirosyan on the scorecards in a fight some ringside observers felt was closer than the judges had it. Those performances positioned him for a shot at a vacant world title within two years.

Charlo won his first world title on May 21, 2016, stopping John Jackson in the eighth round to capture the vacant WBC super welterweight championship. He defended it several times, including a brutal first-round knockout of previously unbeaten Erickson Lubin in October 2017, before a controversial split-decision loss to Tony Harrison in December 2018 cost him the belt. He avenged that defeat convincingly in a December 2019 rematch, stopping Harrison in the eleventh round to reclaim the title.

His breakthrough into the sport’s undisputed conversation came against Argentina’s Brian Castano. Their first meeting in June 2021 ended in a hotly debated split draw, but the May 2022 rematch settled the argument emphatically: Charlo dropped Castano twice and stopped him in the tenth round, unifying every major belt in the division. The full record of that historic rivalry is detailed on Wikipedia’s dedicated page for the Charlo-Castano fights.

With the Castano rematch, Charlo became the first male boxer of the four-belt era to hold the WBA, WBC, IBF and WBO titles simultaneously in the same division, and the first undisputed super welterweight champion since Winky Wright in 2004. He had already unified three of those belts in September 2020 by knocking out Jeison Rosario in the eighth round. His professional record stands at 35 wins, 2 losses and 1 draw, with 19 of those victories coming by knockout, and he held The Ring magazine’s 154-pound championship from 2020 to 2024.

Charlo’s achievement was amplified by the fact that his twin brother Jermall was simultaneously reigning as WBC middleweight champion, a genuinely unprecedented feat for siblings in boxing history. Coverage of undisputed champions across the sport’s four-belt era, including Charlo’s place in that short list, is examined by CBS Sports.

Charlo’s biggest mainstream moment came when he moved up two weight classes to challenge Canelo Alvarez for the undisputed super middleweight championship on September 30, 2023, at T-Mobile Arena in Las Vegas. Alvarez dropped Charlo in the seventh round and won a wide unanimous decision, but the event itself, a genuine pay-per-view crossover fight, drew an estimated 700,000 buys and roughly $59.5 million in revenue, putting Charlo in front of by far the largest audience of his career.

That single fight did more to raise Charlo’s public profile outside hardcore boxing circles than any of his title reigns at 154 pounds, since it paired him with the sport’s biggest pay-per-view draw on one of the year’s marquee cards. Financial analysis of the event and Alvarez’s blockbuster earnings from it, with Charlo’s participation as the vehicle, was covered by Sportico.

Charlo’s fight purses have historically been supplemented by a modest but real endorsement portfolio rather than blockbuster individual sponsorship deals typical of larger crossover stars. His most notable outside partnership has been with actor Mark Wahlberg’s sports-inspired apparel brand Municipal, which Wahlberg launched in 2019, with Charlo appearing in the brand’s clothing and promoting it on social media. That relationship, along with a broader look at his income outside the ring, is detailed by EssentiallySports.

As with most boxers outside the very top tier of pay-per-view draws, Charlo’s television and event income runs primarily through his promotional and broadcast arrangements rather than separate consumer-brand endorsements, and the financial terms of his individual sponsorship agreements have not been made public.

Charlo and his twin brother co-founded Lions Only Promotions, a promotional company that has grown beyond simply co-promoting the brothers’ own fight cards. It now operates as a small stable for other boxers, with Charlo describing his role as mentoring roughly five or six signed fighters, and has expanded into a video production arm and an in-house clothing line sold through charloboxing.com. Charlo has spoken about learning the promotional side of the business from conversations with fellow champion Errol Spence Jr. and longtime manager Al Haymon, details covered by FanSided.

The clothing line trades under the Charlo Boxing name and is tied to a physical location, Charlo Boxing and Fitness Club in Sugar Land, Texas, which the brothers have also used as a community and training hub outside of fight camps. Neither Lions Only Promotions nor the merchandise business has disclosed independent revenue figures publicly.

Charlo owns a large family home in the Houston area featuring a garage built into the property, a basketball court, a game room and a private movie theater, though the purchase price and exact address have not been publicly disclosed. His car collection has included a Lamborghini Aventador valued at more than $400,000, a Rolls-Royce, a Mercedes-Benz G-Class and a custom lifted truck, alongside a jewelry purchase reported at $553,000 in 2019 that included a $358,000 Audemars Piguet watch and a $100,000 diamond Cuban link chain. Those figures were compiled by MEAWW’s review of his assets and net worth.

No real estate holdings beyond his primary Houston residence, and no additional investment properties, have been verified by any outlet reporting on his finances.
