Walmart makes money primarily through high-volume retail sales at low prices, with grocery and consumables anchoring customer traffic. The company adds scale through general merchandise, health and wellness, fuel, eCommerce, marketplace activity, advertising, delivery services, and membership fees from Samâs Club and Walmart+.
â
In Q1 FY2027, for the three months ended April 30, 2026, Walmart generated total revenue of $177.8 billion, up 7.3% year over year. Net sales were $175.7 billion, up 7.1%, and operating income was $7.5 billion, up 5.0%. Adjusted operating income rose 7.6% to $7.7 billion.

Walmart operates through three main segments
â
- Walmart U.S.: The largest segment, with Q1 FY2027 net sales of $117.2 billion, up 4.5%. Comparable sales excluding fuel rose 4.1%, supported by 3.0% transaction growth and 1.1% average ticket growth. This segment includes U.S. supercenters, discount stores, Neighborhood Markets, eCommerce, marketplace, advertising, pharmacy, and Walmart+.
- Walmart International: A diversified international retail business with Q1 FY2027 net sales of $35.1 billion, up 18.0% reported and 10.1% in constant currency. Operating income rose 23.9% reported to $1.6 billion. China is meaningful within this segment through Walmart China and Samâs Club China, although China is not reported as a standalone segment.
- Samâs Club U.S.: A membership warehouse club business with Q1 FY2027 net sales of $23.4 billion, up 6.1%. Comparable sales excluding fuel rose 3.9%, driven by 6.2% transaction growth. Membership fee revenue at Samâs Club U.S. rose 5.6%.
â
Walmartâs main revenue streams are
â
- Product sales: Store, club, and online sales across grocery, consumables, general merchandise, health and wellness, and fuel.
- Membership fees: Recurring revenue from Samâs Club and Walmart+, with global membership fee revenue up 17.4% in Q1 FY2027.
- eCommerce and marketplace: Online retail, third-party marketplace sales, pickup, and delivery. Global eCommerce sales rose 26% in Q1 FY2027, including 26% growth in Walmart U.S., 27% growth in Walmart International, and 23% growth at Samâs Club U.S.
- Advertising and retail media: Walmart sells advertising through its retail media platforms, supported by large customer reach and purchase data. Global advertising grew 37% in Q1 FY2027, while Walmart U.S. advertising rose 36%.
- Delivery and commerce services: The company earns revenue from delivery, fulfillment, marketplace services, and related technology-enabled commerce solutions.
â
Walmartâs core advantage is scale. The company reported FY2026 revenue of $713 billion, about 2.1 million associates, approximately 280 million weekly customers and members, and more than 10,900 stores across 19 countries. This gives Walmart purchasing power, logistics density, data depth, and the ability to spread technology and supply-chain investments across a large revenue base.
â
The companyâs store base is also a fulfillment asset. Walmart uses stores and clubs as local nodes for pickup and delivery, which supports faster service and helps eCommerce growth while keeping customers inside the Walmart ecosystem. This model differs from Amazonâs more centralized eCommerce and cloud-led business mix, although both companies compete directly in online retail, marketplace, delivery, advertising, and membership.
â
Walmartâs market position is strongest in U.S. mass retail and grocery. In Q1 FY2027, the company reported broad-based market share gains, led by grocery and general merchandise and by upper-income households. This is important because Walmartâs value positioning is strongest during periods when consumers focus on price, yet the company is also attracting higher-income shoppers through convenience, delivery, and digital services.
â
Direct competitors include Amazon, Costco, Target, Kroger, BJâs Wholesale Club, regional grocers, dollar stores, and international retail chains. Samâs Club U.S. competes most directly with Costco and BJâs in warehouse clubs. Costco remains the clearest peer for the club model, while Amazon is Walmartâs most important competitor in eCommerce, marketplace, delivery, advertising, and subscription-based customer relationships.
â
Walmartâs business model remains lower-margin than many digital platforms, so execution in higher-margin areas matters. Advertising, membership, marketplace services, automation, AI-powered tools, and supply-chain productivity are central to its margin expansion strategy. The companyâs FY2027 guidance calls for constant-currency net sales growth of 3.5% to 4.5% and adjusted operating income growth of 6.0% to 8.0%, indicating management expects profit growth to outpace sales growth.
