Confidence rating:

About half of Musk's fortune is derived from publicly traded carmaker Tesla, which became the state of California's biggest auto-industry employer, and closely held rocket business SpaceX, which counts the U.S. National Aeronautics and Space Administration as a client. 

Musk owns about 20 percent of Tesla, which acquired his SolarCity alternative energy business in 2016, according to a September 2016 merger prospectus. He owns about 33 million Tesla shares and 4.2 million exercisable options, according to the company's 2018 proxy. He controls the stake through a revocable trust and has pledged 13.8 million shares as collateral against personal obligations, according to the proxy. These shares are included in the net worth analysis and their value offset by a $624.3 million liability, the amount of borrowings against them, as disclosed in a March 2017 filing.

SpaceX is valued using the details from a November 2017 fundraising round that valued the company at $21.5 billion, according to documents reviewed by researcher Equidate. Musk owns 53 percent of the closely held company through a trust, according to a Nov. 15, 2016 filing with the Federal Communications Commission. The analysis assumes he didn't sell shares in the 2017 fundraising. His stake has been diluted in proportion to the amount raised. The value is reduced by 15 percent to account for typical discounts that shares in startups attract on the secondary market, according to two brokers who asked not to be identified because the information is private. 

His investment in tunneling venture Boring Company is valued at cost.

Spokesmen for Tesla and SpaceX declined to comment on Musk's net worth.


Birthdate: 6/28/1971
Family: Single, 5 children
Education: 1997, Wharton School of The University of Pennsylvania, Bachelor's Degree, Business 1995, Trustees of The University of Pennsylvania/The, Bachelor's Degree, Physics

Born in South Africa to an engineer father and nutritionist mother, Musk left home as a 17-year-old for college in Canada, in part to avoid serving in the apartheid-era South African army. After graduating from the University of Pennsylvania with degrees in physics and economics, he enrolled at Stanford University. He dropped out after his first few days to pursue his three main areas of interest: the Internet, clean energy and space.

He created an online publishing platform called Zip2 in 1995 and sold it four years later for more than $300 million. He reinvested some of the proceeds to start, an online payment system. He would merge that with what eventually became PayPal, the e-commerce site that was ultimately sold to eBay for $1.5 billion in 2002.

His next project: SpaceX, a closely held rocket company that was tapped by NASA to take over space shuttle's role of resupplying the International Space Station. A year later, he founded Tesla Motors, a Palo Alto, California-based company that produced the world's first all-electric, zero-emission sports car in 2010, the same year the company sold shares in a public offering.

His third company, SolarCity, is the biggest provider of solar power systems in the U.S. Managed by his cousins, Peter and Lyndon Rive, SolarCity sold shares in a public offering in 2012 and was bought by Tesla on Nov. 21, 2016.

Musk, who recently said he intended to retire on planet Mars, joined Warren Buffett's Giving Pledge in April 2012.
