The online retailer famously founded by Jeff Bezos in his garage during the 1990s has long led Walmart in market capitalization but hadn’t passed Walmart in earnings. Until now. In its earnings release after the close of trading today, Amazon is expected to report revenue of $187 billion, according to analysts. Walmart reports on Feb. 20, and is projected to announce sales of $180 billion.
