Confidence rating:

The majority of Ross's fortune is derived from his ownership of New York-based Related Cos., the closely held real estate business he founded in 1972. Related has a real estate portfolio valued at more than $60 billion, including luxury condominiums, affordable housing and bespoke company headquarters, according to its website.

The size of Ross's interest in these properties isn't disclosed. Bloomberg calculates the company's net value by subtracting debt from the sum of market value of its properties. Ross is credited with 50% ownership of the balance, based on discussions with analysts at CBRE and Cushman Wakefield.

Ross is assumed to own 95% of the Miami Dolphins professional football team, according to information that used to appear on its website. The franchise is valued based on a September 2021 report by valuation consultants Sportico.

Fitness chain Equinox has about 100 clubs, according to a Jan. 29, 2019 press release, and Related's stake is valued using the $18 million price-per-club paid by the chain for six clubs in 2014. A 25% discount was added in December 2020. Its 97% stake in SoulCycle is valued separately using the price paid for a 25% stake in the company in May 2015 and net of debt, according to SoulCycle's August 2015 prospectus.

A re-calculation of Related's debt on Sept. 15, 2021 led to a fall in the valuation of $1.2 billion.

Jon Weinstein, a spokesperson at Related Cos., declined to comment on the net worth calculation.
