Ross is also the principal owner of the Miami Dolphins and Hard Rock Stadium.

Ross is a major benefactor of his alma mater, the University of Michigan; with lifetime contributions of $478 million to the university, he is the largest donor in the university's history. According to the Chronicle of Philanthropy, his higher education gifts rank behind only those of fellow American billionaire New York City mayor Michael Bloomberg. The University of Michigan renamed its business school to the Ross School of Business in Ross's honor, in 2004, after he made a $100 million gift to fund a new business-school building. The Stephen M. Ross Academic Center was completed in January 2006. In September 2013, Ross donated $200 million to the university ($100 million to the business school and $100 million to Michigan athletics), the largest single gift in the history of the university; the University of Michigan announced plans to rename the university's athletics campus in his honor.

Early life and education Born and raised in Detroit, Stephen Michael Ross grew up in a Jewish family. He first attended Mumford High School in Detroit and later graduated from Miami Beach Senior High School. He attended the University of Florida for two years before transferring to the University of Michigan, where he earned a Bachelor of Business Administration degree in 1962. He later received a Juris Doctor from Wayne State University in 1965 and a Master of Laws in Taxation from the New York University School of Law in 1966.

Career Ross began his career as a tax attorney at Coopers & Lybrand in Detroit. In 1968, he moved to New York City and accepted a position as an assistant vice president in the real estate subsidiary of Laird Inc., then worked in the corporate finance department of Bear Stearns. In 1972, he was fired from that company after clashing with a superior; living off $10,000 ($67,000 in 2021 dollars) lent to him by his mother, he utilized his federal tax law knowledge to organize deals for wealthy investors, allowing them to shelter income with the generous incentives granted by the federal government to promote the construction of federally subsidized affordable housing. Related originally began as the Related Housing Companies, which built thousands of subsidized low and moderate income apartments nationwide. 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. 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." 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) on Manhattan's west side. 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. Ross has continued as non-executive chairman of Related Companies.

Ross 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. In January 2026, Ross committed $50m to help develop a Vanderbilt University campus in West Palm Beach. On April 2, 2026, Related Ross broke ground for a 28-story condominium along the water in West Palm Beach.

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. 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. The Dolphins wanted $3 million a year for the next 30 years, with Ross committed to funding 70% of the cost.

Since 2019, the Miami Open has been hosted at the Hard Rock Stadium.

On February 1, 2022, Ross and the Dolphins, among other teams, were cited in a federal class-action lawsuit brought forth by his former head coach Brian Flores, alleging that Ross offered Flores a $100,000 bonus for every game he lost in the Dolphins’ 2019 campaign. As of February 2, 2022, the NFL publicly denied all allegations against Ross and all others listed in the lawsuit, releasing in an official statement: "We will defend against these claims, which are without merit."

On August 2, 2022, following a six-month independent investigation by Mary Jo White and a team of lawyers, it was announced that the NFL would strip the Dolphins of their 2023 first-round draft pick and a 2024 third-round draft pick for violating the league's anti-tampering policy on three occasions from 2019 to 2022 by engaging in impermissible conversations with quarterback Tom Brady and then-New Orleans Saints coach Sean Payton, both of whom were under contract with other teams. Vice chairman and limited partner Bruce Beal was fined $500,000 and was not permitted to attend any league meetings for the rest of the 2022 season. The investigation did not find that the Dolphins intentionally lost games during the 2019 season.

In December 2024, Ross struck a deal to sell a 10% stake in the Dolphins to private equity giant Ares Management, at an $8.1 billion valuation. Ross also sold a 3% stake in the team to Alibaba co-founder Joe Tsai. The stake sales were among the first under new NFL rules that allowed PE firms to buy minority stakes in teams, a practice seen in the NBA and other pro sports leagues.

In March 2026, Ross sold 1% of his stake in the holding company behind the Dolphins for $125 million, valuing the company at $12.5 billion, a record valuation for a minority transaction in sports. Ross sold the 1% stake to Lin Bin, the co-founder of Xiaomi.

F1 Ross owns the Miami International Autodrome, a purpose-built temporary circuit around Hard Rock Stadium. The Formula One Grand Prix was held there for the first time during the 2022 season. Ross had been trying to bring about the Miami Grand Prix for several years before being successful. The circuit layout is designed in a way that local residents would not be disrupted by the races. It is also one of the newest racetracks in the United States. In 2024, there were minor tweaks made to the circuit, including resurfacing the track. RSE builds, owns and operates a variety of companies, including the Drone Racing League, Thuzio, VaynerMedia, and Relevent.
