Introduction to Supermarkets
Supermarkets aren’t just places to shop — they’re stitched into everyday life. These are where millions pick up their bread, their detergent, their dinner. Big, open aisles packed with groceries, toiletries, pet food, you name it. The idea? Everything in one stop. And fast.
Their rise wasn’t accidental. In the mid-1900s, as cars and suburbs expanded, people moved away from small-town corner shops. Supermarkets filled the gap. They offered scale, lower prices, and convenience. Since then, they’ve become a standard feature of towns and cities across the globe — shaping how food is grown, how it’s distributed, and how it ends up in your basket.
They also drive economies. Millions work in this sector — in logistics, warehousing, management, store ops. Big supermarket chains don’t just respond to demand. They influence what people want. They set trends. If a chain shifts to organic, suppliers follow. If they cut out plastic, packaging changes across continents. These are not just retailers. They’re global systems.
What Determines the Biggest Supermarkets?
When we talk about the world’s largest supermarkets, we’re not just counting stores. It comes down to revenue — how much each company brings in over a year. For public companies, that’s listed in their financial reports. Private chains? Analysts and market experts provide the best available estimates.
Size also shows in physical scale: store count, countries served, number of employees. The more stores you have, the more customers you reach. The more staff you employ, the bigger your operations. Together, revenue, reach, and workforce reveal the true footprint of each brand.
Top 10 Supermarkets by Revenue
| Supermarket Name | Country of Origin | Revenue (USD) | Number of Locations |
|---|---|---|---|
| Walmart | United States | $611 billion | 10,500+ |
| Costco | United States | $226 billion | 805 |
| Amazon (Whole Foods Market) | United States | $469 billion | 525 |
| Aldi | Germany | $107 billion | 10,000+ |
| Schwarz Group (Lidl) | Germany | $125 billion | 11,000+ |
| Tesco | United Kingdom | $89 billion | 6,800 |
| Carrefour | France | $85 billion | 12,300 |
| Ahold Delhaize | Netherlands | $38 billion | 2,000+ |
| Seven & I Holdings | Japan | $37 billion | 21,000+ |
| Billa | Austria | $10 billion | 1,000+ |
These numbers show who’s really driving the global grocery game — not just by profits, but by presence.
Walmart: Still on Top
Walmart didn’t just grow. It expanded with intent. One store in Arkansas in 1962 turned into a worldwide network. Sam Walton’s goal? Low prices. Big volume. High efficiency. The result? $600+ billion in yearly revenue and more than 10,500 stores in 24 countries.
Wherever it opens, Walmart changes things. It hires. It sources. It undercuts. Local shops often can’t keep up. But for consumers, the upside is clear: more for less. Behind that? A logistics empire — predictive inventory, tight supply chains, and deep investments in tech.
In the age of online retail, Walmart has adapted fast. Curbside pickup, online groceries, and hybrid retail models help it compete with digital-first giants. Walmart isn’t just retail. It’s infrastructure.
Costco: Bulk, Loyalty, and Scale
Costco doesn’t need to shout. Its model is quiet — and smart. Members pay to shop. And they stay loyal. The stores are plain. The products are few. But the value is strong. Founded in 1983, Costco now earns over $200 billion a year.
You’ll find bulk goods, trusted brands, and lean operations. And because the membership fees bring in consistent revenue, the company can keep prices low. That structure — fewer SKUs, big volumes — keeps operations efficient.
Costco keeps expanding. Canada. Japan. Mexico. Korea. And now, a growing online presence, too. It isn’t trendy. But it works.
Amazon’s Grocery Disruption
Amazon didn’t step into food retail. It broke in. First came Amazon Fresh — digital, delivery-focused, no physical stores. Then it bought Whole Foods. That was the turning point.
With physical stores under its belt, Amazon blurred the lines between online and offline. Prime deals. Walk-out tech. Smart pricing. Every visit generates data. Every purchase feeds the system.
During COVID, Amazon’s grocery model scaled fast. While others scrambled, it delivered. Now, its mix of online grocery, physical stores, and predictive supply makes it a different kind of player. Not a supermarket. A service engine.
Aldi, Lidl, Tesco and More
Aldi runs on simplicity. Store-brand products. Low overhead. No extras. That’s helped it grow fast across Europe, the U.S., and beyond.
Lidl — owned by Schwarz Group — takes a similar path: tight selections, rapid expansion, sharp pricing. It has over 11,000 stores and is growing fast in the U.S.
Tesco leads in the UK. But its presence stretches well beyond — with strong digital systems, loyalty programs, and a focus on sustainability.
Carrefour, France’s retail giant, mixes formats — from hypermarkets to local stores — across Europe, Asia, and South America. Big footprint. Diverse model.
Ahold Delhaize combines Dutch and Belgian legacy. Its banners — from Albert Heijn to Food Lion — make it a key player in Europe and the U.S.
Seven & I Holdings, owner of 7-Eleven, runs over 21,000 stores. Convenience is its game. But in Japan and across Asia, these stores offer much more than snacks.
Billa, Austria’s chain, focuses on central and eastern Europe. It’s smaller, but strategic.
How Supermarkets Shape Local Economies
A supermarket opens, and the local map shifts. New jobs appear. Foot traffic increases. Property values change. Prices drop for basics. Other businesses try to move in nearby.
But the flipside is real. Small shops often lose out. Local suppliers can’t compete on price. Personal shopping experiences fade. Local character? Sometimes gone.
Still, the right mix can work — where global chains, local markets, and small businesses each have room. That balance takes planning — and policies that protect small players.
