In 1972, Ross founded Related Companies, a real estate development company.[18] Related originally began as the Related Housing Companies, which built thousands of subsidized low and moderate income apartments nationwide.[19] By the 1980s, Ross turned towards higher-profile projects. He hired architect Robert A.M. Stern in the 1990s to design The Chatham on the corner of 65th Street and Third Avenue.[19]
Headquartered in New York City, Related now has offices and real estate developments in Boston, Chicago, Los Angeles, Dallas, Washington, D.C., South Florida, Abu Dhabi, and London. The company directly employs approximately 4,000 people.[20][21] The company's existing portfolio of real estate assets, valued at over $60 billion, is made up of mixed-use, residential, retail, office, trade show and affordable properties in what the company calls "premier high-barrier-to-entry markets."[21]
Related is the largest owner of luxury residential rental properties with over 40,000 units in its portfolio[22] and has developed mixed-use projects such as Deutsche Bank Center in New York, CityPlace in West Palm Beach, The Grand in Los Angeles (designed by Frank Gehry)[19] and the 28-acre Hudson Yards project[23] on Manhattan's west side.[24] Hudson Yards is the largest and most expensive real-estate project in America — at almost a billion dollars an acre. Ross constructed an atrium inside Hudson Yards specifically to entice Coach into moving into the development.[19] Related is also a major investor in Equinox Fitness Clubs, SoulCycle and fast casual restaurant chains.[20][21]
The company announced in July 2024 that Ross would be stepping down as chairman of Related Companies to focus on his business ventures via Related Ross, the Miami Dolphins, and F1. Ross will continue to serve as nonexecutive chairman of Related Companies.[25]
Via Related Ross, the developer is looking to invest $10 billion to turn West Palm Beach into a financial hub, with plans for six million square feet of office space, 1.4 million square feet of condos, and nearly 900 hotel rooms across the 70 acres of land he’s amassed over the last two decades. In December 2025, Related Ross received a $772 million loan, one of the largest construction loans in Florida history, for two office towers in West Palm Beach.[26][27] On April 2, 2026, Related Ross broke ground for a 28-story condominium along the water in West Palm Beach.[28]
Miami Dolphins
In February 2008, Ross bought 50% of the Miami Dolphins franchise, Dolphin Stadium (now known as Hard Rock Stadium), and surrounding land from then-owner Wayne Huizenga for $550 million, with an agreement to later become the Dolphins' managing general partner. On January 20, 2009, Ross closed on the purchase of an additional 45% of the team from Huizenga. The total value of the deal was $1.1 billion.[29][30] This means Ross is now the owner of 95% of both the franchise and the stadium. Ross announced his intention to keep Bill Parcells as the director of football operations.[4]
Since buying the Dolphins, Ross has brought in Gloria Estefan, Marc Anthony, Venus Williams, and Serena Williams as minority owners of the team. In 2013, Roger Goodell made a pitch to the Florida legislature on Ross’ behalf in order to obtain multimillion-dollar public funding from the state to help renovate Hard Rock Stadium, the Dolphins' home field.[31]
RSE Ventures
RSE Ventures is a private investment firm that focuses on sports and entertainment, media and marketing, food and lifestyle, and technology. RSE Ventures was co-founded in 2012 by Ross and Matt Higgins, former executive vice president of the New York Jets.[40][41] RSE builds, owns and operates a variety of companies, including the Drone Racing League, Thuzio, VaynerMedia, and Relevent.[42][43]
