[Musk: My 'net worth' almost entirely comes from my shares in Tesla and SpaceX] According to a report by Golden Finance, Musk responded to claims that he is about to become a trillionaire, saying, 'My "net worth" almost entirely comes from my shares in Tesla and SpaceX. My cash is less than 0.1%. All Tesla and SpaceX employees hold stock/options, and more than 80% of Tesla's shares are held by retail investors and index/pension funds, so the growth in (company) value benefits these people.'
