The world's largest retailer by revenue is Walmart, the American chain founded by Sam Walton.
Sam Walton opened the first Walmart store in Rogers, Arkansas, on July 2, 1962, with his brother James “Bud” Walton. The business grew by emphasizing low prices, efficient distribution, and stores in smaller communities that larger department-store chains often overlooked. Walmart later expanded internationally and added Sam’s Club warehouse stores.
Walmart’s revenue leadership refers to retail revenue, a measure that places it ahead of other major retailers such as Amazon, Costco, and Kroger. Amazon is sometimes described as the world’s largest company by revenue in broader rankings because its technology and cloud businesses are included, but Walmart remains the leading retailer by retail revenue in standard industry comparisons.
The company is headquartered in Bentonville, Arkansas, and remains closely associated with the Walton family, which retains a major ownership stake. Its name is often written simply as “Walmart,” although the corporate entity is Walmart Inc.
