Amazon.com, Inc. vs Walmart Inc.: Strategic Comparison

This in-depth comparison examines Amazon.com, Inc. and Walmart Inc. across revenue, market value, business model, competitive positioning, and long-term growth strategy. Whether you are researching Amazon.com, Inc. on its own, evaluating Walmart Inc., or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between Amazon.com, Inc. and Walmart Inc. is widest.

On the headline numbers, annual revenue is $716.9B (FY2025) for Amazon.com, Inc. and $713.2B (FY2026) for Walmart Inc., while their respective market capitalizations stand at $2.69T and $790.0B. Both Amazon.com, Inc. and Walmart Inc. are headquartered in United States. Their local markets and applicable rules may still differ.

Amazon.com, Inc.: Amazon started as an online bookstore in 1994 and now runs four businesses of real scale: the world's largest e-commerce marketplace, a logistics network that carries most of its own parcels, AWS, and a $68.6B advertising operation. It also owns Whole Foods Market, Prime Video and Amazon MGM Studios, One Medical, and Amazon Leo, its low Earth orbit satellite network. The company reads more like infrastructure than retail: other businesses run on AWS, sell through its marketplace, ship through its fulfillment network, and buy its ads. The company is headquartered in Seattle, Washington. The legendary "everything store" notoriously began in a small garage in Bellevue, Washington as a simple online bookseller before aggressively expanding into retail, cloud computing, and global logistics.

Walmart Inc.: Walmart is a public retailer listed on Nasdaq as WMT since December 2025, after more than five decades on the New York Stock Exchange. It reported $713.2 billion in FY2026 revenue and is led by President and CEO John Furner. The company is headquartered in Bentonville, Arkansas.

Amazon.com, Inc. and Walmart Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Amazon.com, Inc. and Walmart Inc..

Amazon.com, Inc. business model: Amazon runs a hybrid model: it buys inventory and sells it directly, and it rents its store, warehouses, and ad inventory to independent sellers. In FY2025 online stores produced $269.3B of net sales, third-party seller services $172.2B, advertising services $68.6B, subscription services $49.6B, physical stores $22.6B, and AWS $128.7B. Marketplace referral commissions typically run in the mid-teens as a share of the sale price, and sellers pay separately for Fulfillment by Amazon and for advertising placement. Retail earns thin margins but collects cash from customers before it pays suppliers, which funds expansion without borrowing. Profit sits in AWS, which turned $128.7B of net sales into $45.6B of operating income, and in advertising, where Amazon charges for placement against shopping queries.

Walmart Inc. business model: Most of Walmart's revenue comes from selling groceries, consumables, general merchandise, health and wellness products, and fuel through stores, clubs, and ecommerce. Walmart U.S. is the largest segment at roughly two-thirds of revenue, followed by Walmart International (including Walmex, Flipkart, Walmart Canada, and Walmart China) and Sam's Club U.S. Retail margins are thin, so Walmart has been building income streams on top of the store base: Walmart Connect and Flipkart advertising, Walmart+ and Sam's Club membership fees, third-party marketplace commissions, and Walmart Fulfillment Services for marketplace sellers. Stores double as pickup and delivery points, which lets Walmart fulfill a large share of online orders from existing inventory.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Amazon.com, Inc. stack up against those of Walmart Inc..

Amazon.com, Inc. competitive advantage: Amazon's advantages depend on scale rather than patents. It carried $534.1B of gross property and equipment at the end of FY2025, including $155.1B of land and buildings and $172.5B of servers and networking equipment, which pays for delivery speed and cloud capacity smaller rivals cannot fund. Prime, priced at $139 a year in the US, changes buying behavior by making each additional order feel free once the fee is paid, and Amazon delivered more than 13 billion items same day or next day in 2025. AWS holds the largest share of global cloud infrastructure spending, about 28% in the fourth quarter of 2025 according to Synergy Research, and customers face real migration cost once applications are built on AWS-specific services. Advertising is the hardest piece to copy, because the ads run against queries from shoppers who are already at the checkout.

Walmart Inc. competitive advantage: Walmart's edge is purchasing scale, a dense U.S. store network that doubles as a fulfillment network, frequent grocery trips, and first-party purchase data that supports its advertising business.

Future prospects matter as much as current results. The growth strategies below explain how Amazon.com, Inc. and Walmart Inc. each plan to expand from here.

Amazon.com, Inc. growth strategy: Amazon's growth now comes mostly from the higher-margin layers on top of its infrastructure. Advertising services grew from $56.2B in FY2024 to $68.6B in FY2025 as Amazon added inventory in Prime Video, grocery, and its demand-side platform. In AWS the company is spending on its own silicon and capacity: the Project Rainier cluster of roughly 500,000 Trainium2 chips, built with Anthropic, became fully operational in October 2025, and Amazon had put $8.0B into Anthropic convertible notes by the end of 2025. Retail growth is being pushed through grocery, pharmacy, and same-day delivery rather than new categories, and Amazon Leo, the satellite network previously called Project Kuiper, is being aimed at commercial connectivity contracts.

Walmart Inc. growth strategy: Walmart is pushing store-fulfilled delivery, marketplace assortment, advertising, and membership while keeping its price position. In Q2 FY27 it reported 23% global ecommerce growth, 38% global advertising growth, 17% higher membership fee revenue, and U.S. marketplace sales up 52%.

A closer look at the financial trajectory of Amazon.com, Inc. and Walmart Inc. rounds out the comparison.

Amazon.com, Inc.: Amazon's headline revenue understates how concentrated its profit is. FY2025 net sales were $716.9B and operating income was $80.0B, of which AWS supplied $45.6B on $128.7B of sales. The North America segment turned $426.3B of sales into $29.6B of operating income, and International turned $161.9B into $4.8B. Advertising services, which Amazon reports inside the retail segments, grew from $56.2B in FY2024 to $68.6B in FY2025. Operating cash flow was $139.5B; $128.3B of net cash capital expenditures left $11.2B of free cash flow, down from $38.2B a year earlier. Amazon says most technology-infrastructure spending supports AWS, while fulfillment capacity also requires investment. See its FY2025 Form 10-K for the segment and cash-flow reconciliations.

Walmart Inc.: Walmart's FY2026 total revenues rose 4.7% to $713.2 billion and net income attributable to Walmart rose to $21.9 billion from $19.4 billion in FY2025. In Q2 FY27 (quarter ended July 31, 2026), total revenues rose 5.9% to $187.9 billion and adjusted EPS was $0.81 versus $0.68 a year earlier. Adjusted operating income growth of about 17% in constant currency included a benefit from roughly $2.9 billion in IEEPA tariff refunds, much of which Walmart said it reinvested in prices. Walmart raised its full-year sales and operating income growth guidance with the Q2 report. Walmart is the world's largest company by revenue and holds a massive market valuation often exceeding $400 billion to $500 billion.
