For the first time since 1996, former President Donald Trump didn't make the annual Forbes 400 ranking of the wealthiest Americans. Tech leaders largely dominated the magazine's 2021 list. Amazon founder Jeff Bezos topped the ranking with an estimated $201 billion net worth. Tesla and SpaceX's Elon Musk landed the No. 2 spot with an estimated $190.5 billion. Facebook founder Mark Zuckerberg and Microsoft founder Bill Gates followed their fellow billionaires.
