MIAMI — Majority control of the Dolphins is “not for sale,” a source told ESPN, after USA Today reported that owner Stephen Ross turned down a $10 billion offer for control of the team, the Formula One Miami Grand Prix and Hard Rock Stadium.

According to USA Today, Ross “entertained” an offer that would represent, by far, the largest team sale in American sports history. He turned down the offer in order to keep team control of the Dolphins within his family; Ross made his daughter, Jennifer, his successor in 2022.

Ross purchased a controlling share of the Dolphins in 2009 and spent $500 million on significant renovations to Hard Rock Stadium in 2015. Ross and Dolphins CEO Tom Garfinkel were instrumental in bringing the Miami Open tennis tournament to the Hard Rock Stadium grounds in 2019 and built the Miami International Autodrome around the stadium three years later to host the Miami Grand Prix in 2022.

Hard Rock Stadium is one of the most versatile sports venues in the United States, hosting college and NFL football games, the Dolphins Challenge Cancer bike ride and 5K fundraiser, and music festivals, along with the Miami Open and the Miami Grand Prix. It will also be a host venue for the FIFA World Cup in 2026.
