ELON MUSK

Elon Musk cofounded six companies including electric car maker Tesla, rocket producer SpaceX and tunneling startup Boring Company.
He owns about 25% 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.
Boring Company, which aims to defeat traffic, raised $675 million in April 2022 at a $5.7 billion valuation.
Twitter's board agreed to sell the company to Musk for $44 billion in April 2022, after he disclosed a 9.1% stake and threatened a hostile takeover.
The deal closed in October 2022 after Musk tried to back out and Twitter sued. Musk now owns an estimated 82% of the company.
