Elon Musk personally is worth more than Exxon Mobil, even though Tesla (worth 800 billion) has never turned a profit.

New York (CNN Business)Elon Musk is rapidly approaching a net worth of $300 billion, as Tesla’s market cap soars past $1 trillion. That’s enough to surpass one of his biggest rivals: ExxonMobil.

As of Monday’s close, Musk’s net worth was $289 billion, according to the Bloomberg Billionaires Index, which surpasses the $272 billion market value of ExxonMobil (XOM), the company most associated with the fossil fuel industry he’s seeking to destroy.
Speaking of rivals: Musk is also worth more than fellow mega-billionaires Bill Gates and Mark Zuckerberg combined.
