Walmart: From a Small-Town Arkansas Store to the World's Largest Company by Revenue

How Sam Walton opened a single discount store in Rogers, Arkansas in 1962 with one obsession — pass every supplier saving to the customer — and built the world's largest company by revenue at $681 billion, employing 2.1 million people across 10,750 stores in 19 countries and serving 270 million customers every single week.

Sam Walton and the Obsession With Low Prices

Samuel Moore Walton was born in 1918 in Kingfisher, Oklahoma, shaped by a Depression-era childhood that gave him a lifelong understanding of what price means to families living close to the edge. After serving in the US Army Intelligence Corps during World War II, Walton opened a Ben Franklin franchise variety store in Newport, Arkansas in 1945 with a $25,000 loan from his father-in-law. He immediately distinguished himself by travelling to suppliers, negotiating better deals, and passing the savings to customers rather than keeping the margin. His store outsold every other Ben Franklin franchise in the region.

When his Newport landlord refused to renew his lease, Walton relocated to Bentonville, Arkansas. He had a theory: rural and small-town customers were being ignored by national retailers who focused only on large cities. They wanted the same range of products and the same low prices as city shoppers, and nobody was giving it to them. On July 2, 1962, Walton opened the first Wal-Mart Discount City store in Rogers, Arkansas. The message was on the door: lowest prices, every day, for everyone.

The Supply Chain Revolution That Changed Retail Forever

Walmart's rise to dominance was not built on marketing or brand personality. It was built on logistics. Walton understood earlier than almost any retailer that the real competition in discount retail happens not on the shop floor but in the supply chain. Every dollar saved in transportation, warehousing, and procurement flows directly to the price difference between Walmart's shelf and a competitor's. From the 1970s onward, Walmart invested systematically in distribution infrastructure: its own truck fleet, regional distribution centres positioned to replenish stores daily, and eventually a proprietary satellite network that gave Walmart real-time inventory data across all its stores before most retailers had computerised their back offices.

The supplier relationship model Walmart pioneered was equally transformative and equally controversial. Walmart's scale gave it purchasing power to dictate terms in ways that were unprecedented. Major consumer goods companies assigned dedicated teams to work on-site at Walmart's Bentonville headquarters, sharing production data to meet Walmart's replenishment demands. Suppliers wanting access to Walmart's enormous customer base had to accept thin margins, continuous price pressure, and complete transparency about their cost structures. Walmart's leverage effectively transferred value from manufacturers to consumers, which was precisely what Sam Walton intended.

"There is only one boss. The customer. And he can fire everybody in the company from the chairman on down, simply by spending his money somewhere else." Sam Walton, Walmart founder

Walmart's Global Business Segments

The Amazon Battle: From Threat to Credible Digital Rival

For most of the 2010s, Walmart appeared to be losing the war with Amazon. Its eCommerce efforts were disjointed and late. The company that had built the world's most efficient physical supply chain struggled to translate those advantages into digital. The wake-up call came as Amazon's grocery ambitions, formalised with the Whole Foods acquisition in 2017, directly targeted Walmart's core business. Walmart responded with urgency. It acquired Jet.com in 2016, launched Walmart+, its $12.95 per month membership programme directly competing with Amazon Prime, and began converting its 4,600+ US store network from a perceived liability into a last-mile fulfilment asset.

Global eCommerce net sales grew 22% in Q4 fiscal 2025. The advertising business, Walmart Connect, grew 24% in the US and 27% globally to $4.4 billion in fiscal 2025, using Walmart's massive first-party purchase data to offer brands targeting capabilities that rival Amazon Advertising. Walmart's physical store network, once seen as Amazon's greatest advantage over the incumbent retailer, is now its own competitive moat: no purely digital retailer can replicate same-day delivery at Walmart's cost structure without owning equivalent physical infrastructure across the country.

According to BBC Business, Walmart's transformation into a credible omnichannel and advertising business represents one of the most successful corporate reinventions in retail history, with a company founded on physical store excellence now generating high-margin digital revenue streams that would have seemed impossible a decade ago.
