Retail scale ≠ profit
Two giant retailers can show similar revenue but very different profit architectures, so supplier impact depends on each customer's margin, promo expectations and cost-to-serve rather than top-line size alone. Analysts compare Amazon and Walmart on these structural differences, and local reporting shows tariffs already affecting shelf prices—both top-down and bottom-up signals that customer-level economics matter.

Amazon and Walmart now report almost the same annual revenue, but they do not earn that money the same way. Amazon posted $716.9 billion for 2025 and Walmart reported $713.2 billion for the fiscal year ended January 31, 2026. (aboutamazon.com, walmart.com) Amazon said operating income reached $80.0 billion in 2025, including $45.6 billion from Amazon Web Services, its cloud unit, on $128.7 billion in sales. Walmart said full-year operating income rose 1.6% while revenue rose 4.7%, and its fourth-quarter growth was helped by advertising, membership fees and eCommerce. (aboutamazon.com, walmart.com) That split shapes how each retailer deals with suppliers. Amazon’s fourth quarter included $12.5 billion in operating income from Amazon Web Services and $11.5 billion from North America retail, while Walmart said its business mix is shifting toward higher-return categories like advertising and membership income. (aboutamazon.com, walmart.com) A supplier selling the same item to both chains can face different demands on price, promotion and delivery because the retailer’s profit pool sits in different places. Walmart still runs a store-heavy model built on high volume and thin merchandise margins, while Amazon can offset retail pressure with profit from cloud computing and other services. (247wallst.com, aboutamazon.com, walmart.com) The cost side is moving too. The Budget Lab at Yale said on April 2 that the average effective United States tariff rate stood at 11.0%, the highest since 1943 excluding 2025, and estimated the price-level effect at 0.5% to 0.6% if the Section 122 tariffs expire after 150 days. (yale.edu) In Bowling Green, Kentucky, WBKO reported on April 12 that import costs are already reaching store shelves. The station said Ali Miah, owner of International Food Market, told reporters he had raised prices on some imported goods after tariff-related cost increases. (wbko.com, msn.com) Walmart told investors that global eCommerce grew 24% in fiscal 2026, advertising rose 46% to nearly $6.4 billion, and membership fee revenue grew 15.1%. Those newer businesses help profits, but the company still ties its brand to low shelf prices in stores and online. (walmart.com) Amazon told investors that North America sales rose 10% to $426.3 billion in 2025, while Amazon Web Services sales rose 20% to $128.7 billion. That gives Amazon more room to keep retail prices aggressive even when the retail operation itself is not the main earnings engine. (aboutamazon.com) The revenue race now says less than the income statement underneath it. For brands deciding where to spend trade dollars, freight capacity and promotional support, the bigger customer on paper is not always the more profitable account in practice.
