The world's largest retailer, still built on one promise - save people money so they can live better.
Walmart Inc., photographed by its own numbers: 10,000-plus stores, roughly 2.1 million associates, and a supply chain that puts a store within 10 miles of most Americans. Sixty-plus years after Sam Walton opened a single discount store in Arkansas.
Walmart sells almost everything a household needs - groceries, clothing, electronics, pharmacy, home goods, toys - through a network of supercenters, discount stores, neighborhood markets, Sam's Club warehouse clubs and a fast-growing website. The scale is the point: enormous purchasing power and a tightly engineered supply chain let the company keep prices low and still turn a profit on thin margins.
The model traces back to 1962, when Sam Walton opened the first Wal-Mart Discount City in Rogers, Arkansas, financing roughly 95% of it himself. His idea was simple and stubborn - offer the lowest prices, in more places, than anyone else. That "everyday low prices" discipline still runs the company, even as it has grown into the largest retailer on Earth.
What has changed is the machinery underneath. Walmart now stitches its physical stores into its digital business, using them as fulfillment hubs for pickup and delivery. Store-fulfilled orders have become one of the biggest drivers of its e-commerce and comparable sales, letting Walmart scale online without copying Amazon's warehouse-only playbook.
Walmart's customer is the value-conscious household - families stretching a budget, shoppers who want one trip to cover groceries and general merchandise, and small businesses buying in bulk at Sam's Club. Roughly 255 million customers and members visit its stores and websites each week worldwide, and around 90% of Americans live within 10 miles of a store.
The core problem Walmart solves is cost. In a market where prices creep up and time is scarce, it offers low prices and broad availability in one place - physically nearby and, increasingly, a tap away. For many communities it is the practical default for weekly essentials.

At its core Walmart makes money the old-fashioned way: sell high volumes of goods at low margins and use scale to squeeze cost out of every step. But the more interesting story of the last few years is how it has layered higher-margin businesses on top - membership fees, the Walmart Connect ad network, marketplace commissions and fintech partnerships. Those streams grow faster and earn more than selling groceries alone.

In a crowded field, three giants have carved distinct promises: Amazon sells convenience, Costco sells trust and curation, and Walmart sells price at massive physical scale. Its real advantage is the network competitors would need decades and billions to copy - distribution centers, trucks, and store proximity that turn every location into a fulfillment point.
That footprint is why Walmart can offer same-day pickup and delivery to a huge share of the country without building a separate warehouse empire. It sits at the center of American retail: the default for weekly essentials, a major grocer, a growing e-commerce player, and now an advertising and technology business. Its competitors include Amazon, Costco, Target, Kroger, Aldi and Dollar General - and internationally, retailers such as Carrefour and Tesco.
