Earlier in 2018, Bezos became the richest person alive. His net worth now totals $166.5 billion, according to Forbes' billionaires list. Going by Forbes' calculations, Bezos is worth roughly twice as much as tech leader Bill Gates and the 'Oracle of Omaha' Warren Buffett.
With revenue of $177.87 billion, as of the company's 2017 fourth-quarter earnings report, Amazon placed eighth on this year's Fortune list of America's largest companies. That's up four spots from its rank last year as No. 12. Amazon made its debut at No. 492 on the Fortune 500 back in 2002, the same year its biggest competitor Walmart first landed in the No. 1 spot. Amazon has since quickly gained on, and nearly caught up with, Walmart.
