Amazon Is About to Dethrone Walmart in a Major Way

Walmart (NYSE: WMT) has been the biggest company in the U.S. by revenue for close to two decades and the biggest company in the world by revenue for much of that time as well. Walmart's revenue is set to clock in around $550 billion this year -- tops in the world by a wide margin. The e-commerce leader is expected to surpass Walmart in U.S. gross merchandise volume (GMV) by next year, according to Evercore ISI, which forecasts Amazon to reach $415 billion GMV next year, ahead of Walmart at $370 billion, though that does not include sales from Sam's Club.
