Elon Musk's net worth exceeds $1 trillion.

Elon Musk is now so wealthy that he's making a mockery of the rich list.The Tesla and SpaceX CEO was worth $1.08 trillion as of Monday's market close, per the Bloomberg Billionaires Index. The next-richest person in the world, Alphabet cofounder Larry Page, was less than a third as wealthy with a net worth of $299 billion.In fact, Musk is richer than the next four people in the billionaire rankings: Page, his cofounder Sergey Brin, Amazon founder Jeff Bezos, and Oracle cofounder Larry Ellison, who were together worth $1.06 trillion as of Monday's close.The sheer scale of Musk's fortune means shifts in others' fortunes now pale in comparison. For example, Page, Brin, and Bezos each lost more than $10 billion in Monday's tech rout.Those losses look paltry compared to Musk's $152 billion wealth decline on the same day, fueled by a 16% plunge in SpaceX's stock just days after its blockbuster IPO.Put differently, Musk lost in one day a sum that exceeds Warren Buffett's entire fortune. The 95-year-old investor and Berkshire Hathaway chairman ranked 10th on Bloomberg's list with a $146 billion net worth at Monday's close.Given Musk has a $700 billion-plus lead over anyone else, he simply looks out of place on a mere billionaires list. He's started a trillionaire club with only one member.
