Gervonta “Tank” Davis was born on November 7, 1994, in Baltimore, Maryland, to parents Garrin Davis and Kenya Brown. According to Wikipedia’s biography of Davis, his childhood was marked by family struggles with addiction and incarceration, and at around age five he and his siblings were placed into foster care by Maryland’s child protective services. That unstable start in the city’s Sandtown-Winchester and Upton neighborhoods is a backdrop Davis has returned to repeatedly in interviews and in the community investments he has made as an adult.

Davis found boxing almost as soon as he entered foster care, joining the Upton Boxing Center under trainer Calvin Ford, a mentor who became a stabilizing figure in his life. CBS News Baltimore’s coverage of his rise traces that gym based upbringing through a decorated amateur career, including a National Golden Gloves championship and two National Junior Olympic titles, before he turned professional on February 22, 2013, with a first round knockout. Early professional purses were modest, reflecting an unheralded prospect building a record rather than a paid star.

Davis met Floyd Mayweather Jr. during a 2015 training camp for fellow Baltimore fighter Adrien Broner and signed with Mayweather Promotions later that year, a relationship that shaped the next phase of his career. Premier Boxing Champions’ profile of the Mayweather mentorship describes how Davis used that platform to win his first world title, the IBF junior lightweight belt, by stopping Jose Pedraza in January 2017 at just 22 years old. The Mayweather association gave Davis both ring exposure and a commercial blueprint he would later apply to his own brand.

Davis has won world titles in three weight classes, from junior lightweight through lightweight and junior welterweight, and became one of boxing’s biggest pay-per-view attractions along the way. His April 2023 fight against Ryan Garcia sold more than 1.2 million pay-per-view units and produced a $22.8 million live gate at T-Mobile Arena in Las Vegas. Bleacher Report’s account of the numbers notes it was the first fight to top a million buys since 2021, placing Davis alongside the sport’s biggest modern draws.

The scale of the Garcia gate is a useful marker of how far Davis’s public profile has traveled from his Upton amateur gym. CBS Sports’ report on the event ranked the $22.8 million gate fifth in Nevada boxing history, behind only Floyd Mayweather’s fights with Manny Pacquiao and Conor McGregor and Canelo Alvarez’s two bouts with Gennadiy Golovkin. That places Davis in company with the handful of boxers who can reliably move a live arena and a subscription pay-per-view audience at the same time, a recognition few active fighters in his weight range can claim.

Davis’s clearest documented endorsement deal came in May 2017, when Under Armour, the Baltimore based sportswear company, signed him as a brand ambassador and marked the deal with billboards along Interstate 95 in his hometown. The Baltimore Sun’s report on the campaign placed Davis alongside fellow Under Armour athletes Michael Phelps and Ray Lewis as a hometown face for the brand. The financial terms were not disclosed, consistent with how most of Davis’s endorsement income is structured around undisclosed appearance and licensing fees rather than public headline figures.

Davis has pursued ventures outside the ring modeled loosely on Mayweather’s own TMT brand, most visibly his GTD apparel branding worn in and around fights. His most tangible business project has been GTD Development, the company behind his plan to buy and renovate properties in the Sandtown-Winchester and Woodyear Street area of West Baltimore where he grew up. Premier Boxing Champions’ report on the redevelopment plan describes the project as an attempt to convert boxing earnings into affordable housing stock in his old neighborhood, though the venture has run into setbacks, including a fire that damaged some of the purchased properties.

Davis’s most prominent personal property is a penthouse at the Silo Point condominium tower in Baltimore’s Locust Point neighborhood, purchased for roughly $3.4 million in 2023. SouthBmore’s report on the purchase covers the unit along with its attached parking and storage space. He also owns a mansion in the Parkland Golf and Country Club area of South Florida, the scene of a 2023 burglary that stripped it of luxury vehicles. That portfolio has not been free of strain: The Baltimore Banner’s coverage of a foreclosure filing reported the Silo Point condo association moved against Davis in 2025 over more than $34,800 in unpaid fees before his attorney said the balance had been settled.
