Can you say no to $10 billion for anything? Well, one Miami sports titan did.

Stephen Ross, owner of the Miami Dolphins, reportedly entertained but ultimately rejected an offer of $10 billion for ownership of the NFL franchise, as well as the team’s home arena, Hard Rock Stadium, and the Formula 1 Miami Grand Prix, according to a report by USA TODAY Sports.

According to the report, the 83-year-old Ross, who’s known for his real estate development company The Related Companies, rejected the $10 billion offer because he wants to keep his assets within the family.

While selling off the assets for $10 billion might seem like a proposal that’s too hard to refuse, the growth of sports valuations in recent years makes it feasible that the value of the assets only continues to grow.

The Dolphins alone were valued at $5.7 billion by Forbes in 2023, 11th highest among the 32 NFL franchises, and was up 24% versus the previous year. That was the second-highest percentage value increase of all NFL franchises last year, but collectively, the league still saw 14% growth among its teams.

The value of a single F1 race is unclear, though the 2023 Miami GP brought in $350 million in economic impact for the city of Miami over just one weekend, according to a report by Applied Analysis.
