Walmart vs Costco: Which Company Has Better Technology?

Walmart is the clear technology leader by capability and reach. Costco's quieter achievement is designing a retail model that needs less technological complexity to work.

“Better technology” needs two scorecards

One scorecard asks which retailer has more sophisticated systems. Walmart wins it comfortably. The second asks whether the technology fits the operating model without adding needless cost. Costco is much more competitive there. A forklift moving a full pallet to the sales floor can be a better system than a robot picking individual units when the business deliberately sells cases in high volume.

The companies are not running differently branded versions of the same store. Walmart describes itself in its fiscal 2026 annual report as a technology-powered omnichannel retailer serving customers through stores, websites and mobile apps. Costco says its economics come from a limited selection, rapid inventory turnover, volume purchasing, reduced handling and no-frills warehouses. Their technology stacks reflect those choices.

Walmart’s supply chain is the stronger technical system

Walmart coordinates a vast assortment across stores, fulfillment centers, marketplace sellers, pickup windows and home delivery. Automation is becoming part of the normal network rather than an isolated experiment. In its February 2026 earnings call, the company said about 60% of US stores were receiving at least some freight from automated distribution centers and about half of e-commerce fulfillment-center volume was automated. Management connected that automation with better inventory visibility and labor productivity.

That is a meaningful advantage: software must know what is available, where it should go and whether a store, warehouse or seller can fulfill an order fastest. Robotics then makes part of the physical decision executable. The result is not a fully autonomous retailer, and company percentages are not independent performance tests, but the documented scale is well beyond what Costco publicly describes.

Costco simplifies before it automates. Its 2025 annual report says most merchandise is purchased directly from suppliers and routed through cross-docking depots or straight to warehouses. Goods are commonly displayed on the same pallets used for transport, while stock sits in racks above the floor. That design removes unpacking, shelf replenishment and piece-picking work. It is operational engineering, even when the visible tools are conventional.

Walmart also wins the customer-facing digital comparison

Walmart has spent years joining its store network to online shopping: marketplace, pickup, delivery, Walmart+ and store-fulfilled orders live inside one broader ecosystem. Fiscal 2026 results reported 24% global e-commerce growth, led by store-fulfilled pickup and delivery and marketplace. That does not prove its app is always easier to use, but it shows digital fulfillment is central to growth rather than an accessory to visiting a store.

Costco has a functional digital business, not an absent one. It operates e-commerce sites in eight countries, and its annual report says e-commerce produced about 7% of fiscal 2025 net sales while digitally enabled sales represented about 10%. Members can use a digital membership card and order groceries for same-day delivery. Yet the integration has seams: Costco’s current help material says same-day service is powered by Instacart, uses a separate cart from Costco.com and includes marked-up item prices. That is convenience through a partner, not the same degree of end-to-end ownership.

AI is a Walmart-wide capability, but the evidence needs restraint

Walmart’s annual report explicitly places AI inside its e-commerce and supply-chain investment. The defensible claim is not that every decision is autonomous; it is that Walmart has the data volume, fulfillment network and software organization to apply prediction, search, routing and personalization across many workflows. Names such as “agentic shopping” can change faster than annual filings, so individual app features should be treated as a dated snapshot.

Costco’s public filings are less specific about named AI systems. They do say the company is making substantial technology and IT investments, including digital resilience, websites and mobile applications. That corrects the caricature of Costco as frozen in the 1990s. The evidence supports a narrower conclusion: Costco modernizes its digital foundation while keeping the warehouse proposition primary. It does not support confidently assigning undocumented AI systems to pharmacy, fuel or inventory.

Advertising makes Walmart’s technology commercially broader

Walmart’s technology is not used only to move merchandise. Walmart Connect sells advertising against shopper attention and purchase signals, and the Vizio acquisition added a smart-TV platform and more advertising inventory. For fiscal 2026 Walmart reported that its global advertising business grew 46% to nearly $6.4 billion, including Vizio. This creates another reason to improve identity, measurement, personalization and media systems.

Costco’s flywheel remains membership. Its fiscal 2025 filing reported $5.323 billion in membership fees and a 92.3% renewal rate in the US and Canada. Technology can make joining, renewal and shopping easier, but Costco does not need to become an ad-tech company to make the model work. The comparison is therefore about strategic scope as much as technical competence.

Category verdict: Walmart leads, with one important caveat

If “better” means greater capability, technical ambition and digital reach, choose Walmart. It has built the stronger technology organization and applies it across more of the retail value chain. If “better” means the fewest systems needed to deliver the business promise, Costco deserves more credit than a feature checklist gives it. Its restraint is partly a consequence of good model design.

The fairest verdict is decisive but not dismissive: Walmart is the technology leader; Costco is the simplicity leader. Walmart uses technology to tame complexity and open new revenue streams. Costco avoids much of that complexity in the first place.
