In 2021, Amazon will make more than $386 billion in U.S. e-commerce sales, according to the latest estimates from eMarketer. That’s about $320 billion more than its biggest e-commerce rival in the country, Walmart. In fact, if you combine the U.S. e-commerce sales of the next nine top e-commerce retailers, the total will still be less than Amazon’s this year.

In addition to Amazon, the top five retailers include Walmart with $67.39 billion in sales, eBay with $40.47 billion, Apple with $35.30 billion and The Home Depot with $21.42.
