Walmart operates the Sam's Club warehouse chain and is headquartered in Bentonville, Arkansas.
Walmart was founded by Sam Walton, who opened the first Walmart store in Rogers, Arkansas, in 1962. The company grew by focusing on large stores, discount pricing, efficient distribution, and expansion into small towns and suburban markets. Its corporate headquarters remains in Bentonville, the city associated with the company's origins.
Sam's Club was founded by Walmart in 1983 and operates as a membership-based warehouse retailer. It sells groceries, household goods, electronics, and other products in bulk or warehouse formats. Walmart also operates its namesake stores and a large e-commerce business.
Walmart and Sam's Club are related but are not the same retail brand. Costco is a separate membership-warehouse company and is therefore a frequent source of confusion. Walmart's international operations include stores and digital businesses in multiple countries.
