Friday has been a good day for Jeff Bezos.

Amazon's CEO, who owned 83,933,463 company shares as of Feb. 19, is on track to having a $5 billion day. The company's stock surged more than $59, or nearly 15 percent, to about $449 a share, according to FactSet. (Tweet This).

To put this into perspective, Bezos' one-day paper gain would be larger than the individual market caps of 17 S&P 500 companies.

The company's stock surge came one day after it reported that Amazon Web Services, which includes its cloud business, generated $1.57 billion in revenue during the first quarter, leading Wall Street to nudge off its earnings per share miss.
