The majority of Sobrato's fortune is derived from the real estate he controls through closely held Sobrato Organization. The properties encompass more than 7.5 million square feet of commercial space and 6,700 residential units along the West Coast of the U.S., according to the company's website.

The value of the commercial holdings has been indexed to the performance of West Coast commerical property prices compiled by researcher RCA since December 2014. The base valuation was calculated using the average selling price per square foot of offices owned by Sobrato, according to three Silicon Valley property brokers in 2014.

The value of the residential properties has been indexed to the performance of West Coast residential property prices compiled by researcher RCA since December 2014. The base valuation was calculated using the median list price for homes in California as of December 2014, according to Zillow, an online real estate database.

A 40 percent discount is applied to the properties to account for debt, according to a person familiar with the holdings who asked not to be identified as the information is private. Projects under construction aren't included in the net worth calculation.

Sobrato Capital, the investment arm of Sobrato Organization, has been funded by cash flow from the real estate operations. Its holdings are valued using the asset value of the securities held by its funds, as previously disclosed on its website and confirmed by Sobrato in a May 2017 e-mail.

Sobrato confirmed his family's net worth in a May 2017 email.

John Albert Sobrato was born in San Francisco on May 23, 1939, the son of Italian immigrants John and Ann. His mother sold the family's restaurant business after his father died in 1952, and used the proceeds to invest in real estate. After graduating from Santa Clara University in 1960, Sobrato founded property developer Midtown Realty.

The pair developed 2.3 million square feet of property in Silicon Valley before they split, after which Sobrato established Sobrato Development Companies.

By 1985, Sobrato's commercial real estate holdings had surpassed 5 million square feet. He began to diversify into residential property, developing his first apartment project in San Jose. A year later, Sobrato began to construct Apple's new headquarters in Cupertino, California.

Sobrato is married with three children. He passed the daily operation of the company to his son, John, in 1997. He focuses on his philanthropic giving through the Sobrato Family Organization.
