Walmart makes money primarily through high-volume retailing at low prices. Its core model combines grocery, consumables, health and wellness, general merchandise and fuel sales with procurement scale, dense store coverage and growing digital fulfillment. In Q1 FY2027, the quarter ended April 30, 2026, revenue was $177.8 billion, up 7.3% as reported and 5.9% in constant currency.
The company operates through three reportable segments
- Walmart U.S.: The largest business, with Q1 FY2027 net sales of $117.2 billion, up 4.5%. Comparable sales excluding fuel rose 4.1%, driven by 3.0% transaction growth and a 1.1% increase in average ticket. This segment anchors Walmart’s U.S. grocery, household essentials, pharmacy, general merchandise, pickup, delivery and marketplace operations.
- Walmart International: The global segment generated Q1 net sales of $35.1 billion, up 18.0% as reported and 10.1% in constant currency. Operating income was $1.6 billion, up 23.9% as reported. The segment includes markets such as Mexico and Central America, Canada, China, India through Flipkart and other countries.
- Sam’s Club U.S.: The membership warehouse business produced Q1 net sales of $23.4 billion, up 6.1%. Comparable sales excluding fuel rose 3.9%, while eCommerce sales grew 23%. The segment earns revenue from merchandise sales and recurring membership fees.
Walmart’s revenue base is broad, but its profit mix is shifting. Traditional store sales remain the main source of revenue, while higher-margin businesses are becoming more important. These include retail media and advertising, marketplace commissions and services, fulfillment services, membership fees, financial services and data or technology-enabled partnerships. In Q1 FY2027, global eCommerce sales grew 26%, global advertising grew 37%, Walmart U.S. advertising grew 36% and global membership fee revenue grew 17.4%.
Walmart’s main product and service categories are grocery, consumables, health and wellness, general merchandise, fuel, club merchandise, memberships, eCommerce marketplace services, retail media, fulfillment and selected financial and technology services. Stores increasingly function as fulfillment nodes, supporting pickup, delivery and faster last-mile economics.
The company’s competitive advantages are scale, price perception, store density, grocery frequency, supplier leverage and omnichannel reach. Walmart serves about 280 million weekly customers and members across more than 10,900 stores and eCommerce websites in 19 countries. Its physical network gives it a delivery and pickup advantage in many local markets, while grocery traffic gives the company frequent customer engagement that supports advertising, memberships and digital commerce.
Walmart is one of the largest companies globally by annual revenue, with FY2026 revenue of about $713 billion. It is a defensive retail bellwether with major exposure to U.S. grocery, value-oriented consumer spending and household essentials. In Q1 FY2027, Walmart U.S. reported broad-based share gains, with eCommerce contributing about 530 basis points to comparable sales growth.
Direct competitors include Amazon, Costco, Target, Kroger, Aldi, dollar stores, regional grocers, club retailers and digital marketplaces. Amazon is the most relevant cross-category peer because it competes with Walmart in eCommerce, marketplace services, retail advertising, fulfillment and retail technology. Costco is the closest large-scale warehouse-club peer for Sam’s Club. Kroger, Aldi and regional grocers compete most directly in food retail, while Target and dollar stores overlap in general merchandise, consumables and value shopping.
Compared with Amazon, Walmart has a stronger physical grocery and store-fulfillment base, while Amazon has greater strength in digital-native marketplace scale, cloud infrastructure and Prime-led online engagement. Compared with Costco, Walmart has a broader mass-retail footprint and a larger eCommerce and advertising platform, while Costco has a more concentrated membership warehouse model. Walmart’s market position increasingly depends on combining its store network with digital services, marketplace growth, advertising and recurring membership economics.
China is a meaningful operating market within Walmart International, especially through Walmart stores, Sam’s Club China and omnichannel services. It is not reported as a separate material revenue segment. Investor exposure to China is mainly through local retail operations, Sam’s Club growth, digital delivery, sourcing and tariff or trade-policy sensitivity. Walmart U.S. remains the dominant earnings driver, with Q1 net sales of $117.2 billion compared with $35.1 billion for all of Walmart International.
