The founder and chief executive officer of the retail juggernaut added $10.4 billion to his net worth as Amazon shares rose 13 percent, the most in 2 1/2 years, a day after the company reported quarterly sales and profit that surpassed analysts' estimates. His wealth briefly eclipsed that of Gates, the Microsoft Corp. co-founder, on an intraday basis on July 27, but Amazon shares ended that day lower, leaving Bezos at No. 2.
At the close of U.S. markets Friday, Bezos had a net worth of $93.8 billion, $5.1 billion ahead of Gates on the Bloomberg index, a daily ranking of the world's 500 richest people. Gates, 61, had been the world's richest person since 2013.
Bezos, 53, has added $28.5 billion to his fortune this year. Gates's net worth has climbed by $6.3 billion since year-end, even after he donated $4.6 billion of Microsoft stock to the Bill & Melinda Gates Foundation in August.
