Walmart was the largest US retailer by US sales in 2022, with about $500 billion in sales, more than double the size of runner-up Amazon, according to the National Retail Federation.
Insider Intelligence/eMartker projects that Amazon will outsell Walmart Inc. in US e-commerce sales in 2022, with $392.21 billion to $68.09 billion.
However, with a considerably greater physical store footprint, Walmart leads overall sales.
Costco Wholesale, The Kroger Co., and The Home Depot are the other corporations in the top five that gain from in-store sales. Those firms will benefit as in-store retail media grows in popularity.
