Walmart E-Commerce Soars 25% Globally: How Big Can Digital Get?

Walmart's Q2 FY26 results highlight a significant acceleration in its digital ecosystem, with global e-commerce sales surging 25% and U.S. e-commerce up 26%. This robust growth is fueled by strategic investments in rapid store-fulfilled delivery, which saw a nearly 50% increase, and a booming advertising business, Walmart Connect, up 31%. The company's broad-based digital expansion across all segments, including international and Sam's Club, alongside strong marketplace adoption and membership income growth, firmly establishes e-commerce as a central engine of its overall growth strategy.

Analysis

Walmart's second-quarter fiscal 2026 results reveal a significant acceleration in its digital strategy, cementing e-commerce as a primary growth engine. Global e-commerce sales surged 25%, with the U.S. segment growing even faster at 26%, driven by a nearly 50% increase in store-fulfilled deliveries. This logistical prowess, which enables fulfillment in under three hours for a third of such orders, creates a distinct competitive advantage. The growth is further supported by high-margin ancillary businesses, with the global advertising unit expanding 46% and membership income rising 15.3%, enriching the revenue mix. While Walmart's digital growth outpaces Costco's 14.8% e-commerce comparable sales increase, it faces intense competition from players like BJ's Wholesale, which posted a 34% jump in digitally enabled sales. Despite this strong operational performance, reflected in a 27.7% share price rally over the past year, the stock's valuation appears stretched. Its forward P/E ratio of 34.79 sits above the industry average of 32.03, and it carries a neutral Zacks Rank #3 (Hold) and a C for Value, suggesting that the market has already priced in much of this positive momentum.

Key Decisions for Investors

• Investors should recognize that Walmart's successful execution in e-commerce, rapid delivery, and high-margin advertising validates its long-term growth strategy, but the current premium valuation warrants caution.
• Given the stock's 27.7% run-up and forward P/E ratio exceeding the industry average, new capital allocation may be better deferred pending a more attractive entry point or further evidence of margin expansion from its digital initiatives.
• Monitor key performance indicators such as the growth rate of Walmart Connect and marketplace fulfillment adoption, as sustained high performance in these areas will be critical to justifying the stock's premium valuation against strong digital competition from peers like Costco and BJ's Wholesale.
