Elon Musk cofounded six companies including electric car maker Tesla, rocket producer SpaceX and tunneling startup Boring Company. He owns about 23% of Tesla between stock and options, but has pledged more than half his stock as collateral for loans. SpaceX, founded in 2002, is worth $127 billion after a funding round in May 2022; it quadrupled its value in three years. Hosted on Acast. See acast.com/privacy for more information.
