Elon Musk's estimated net worth has now surpassed $400 billion, according to an estimate from Bloomberg News — the first person ever to reach such a milestone. As Tesla shares hit a new all-time high Wednesday, Musk's wealth leapt to some $440 billion, according to Bloomberg. A separate billionaire index tracked by Forbes pegs Musk's net worth at about $369 billion, with Amazon founder Jeff Bezos at No. Yet Musk's net worth has climbed even without that compensation deal, which is now worth $100 billion. Musk spent much of the year focused on the 2024 election: Federal Election Commission filings show he spent nearly a quarter of $1 billion on helping elect Donald Trump to a second term as president.
