The Maze: Walmart's US ecommerce business grew 24% in a quarter when comparable sales slowed to 2.6%. The split reveals the strategy. Walmart is no longer treating stores as the legacy half of an online business. It is turning local inventory into a distributed fulfillment network: closer goods, shorter delivery promises and more shopping occasions. The store estate once looked like Amazon's digital disadvantage. Now Walmart is using those buildings to make speed a conversion tool—and to wrap marketplace, advertising, membership and fulfillment revenue around the same order.
The physical network is doing digital work. Store-fulfilled delivery grew about 43%, while Walmart Marketplace sales rose 52%, according to the detailed Q2 presentation. Deliveries under three hours represented roughly 37% of store-fulfilled orders. The operating logic is straightforward: inventory already sits near households, store teams pick it, and Walmart's Spark network moves it the final miles. That shortens the promise across groceries and general merchandise without waiting for a purpose-built warehouse in every neighbourhood. Speed becomes part of the product, not a shipping footnote.
Faster promises are changing what customers buy online. Walmart has expanded 30-minute-or-less delivery across selected US markets, covering more than 100,000 eligible items. Its routing logic considers basket size, driver availability and distance from the store. The menu ranges from scheduled slots to on-demand delivery within three hours, Express within one hour and a 30-minute tier that costs Walmart+ members $10. That lets Walmart compete for forgotten groceries, medicine, dog food, batteries and last-minute meal ingredients—the urgent missions shoppers once solved with a store trip or a specialist app.
The ecommerce engine is pulling several revenue streams. Digital sales now represent about 23% of Walmart U.S. revenue, twice the mix of five years ago. Nearly half of Walmart's marketplace business flows through its fulfillment services. More sellers create assortment; fulfillment makes those listings faster; Walmart+ turns convenience into recurring fee income; Walmart Connect sells access to the traffic. The company describes marketplace, fulfillment, membership and advertising as improving the economics of the business. The important shift is not only more online orders. It is more ways to earn from each shopper, seller and parcel moving through the network.
Growth is real, but the quarter was not frictionless. U.S. comparable sales grew just 2.6%, the slowest pace in six years, and shares fell more than 8% as investors weighed cautious expectations. Walmart also used a $2.9 billion tariff refund to support price investment, while higher fuel, claims, depreciation and healthcare costs created pressure elsewhere. The quarter's 20.6% increase in Walmart U.S. operating income therefore cannot be credited to delivery alone. The stronger claim is narrower: Walmart says ecommerce economics improved, and it has now delivered more than 20% domestic ecommerce growth for ten consecutive quarters. Digital is gaining weight even while the consumer backdrop gets harder.
Why it matters: Amazon taught retail that speed can reset customer expectations. Walmart is showing that dense stores can be a different route to the same advantage. For operators, the lesson is not to promise 30 minutes everywhere. It is to treat existing assets as a network: expose local inventory accurately, show a credible delivery promise before checkout, route orders to the cheapest workable node and add paid convenience only where urgency supports it. The winner does not merely ship faster. It makes assortment, delivery, membership, ads and seller services reinforce one another.
