Walmart's US Comp Sales Up 4.5%: Transaction Growth to Last in 2026?

Walmart's U.S. segment posted a 4.5% comp sales gain in Q3 FY2026 led by transaction and unit-volume growth across stores and digital channels, with comps positive each month and share gains broad-based across income cohorts as value and convenience attracted both upper- and middle-income shoppers while lower-income demand was sustained by pricing. Management highlighted omnichannel strength and faster fulfillment—an increasing share of digital orders delivered within three hours—as a key driver of transactions and said disciplined pricing, value focus and speed should support continued U.S. comp growth into FY2026. The stock has outperformed peers over the past year (WMT +22.4% vs. industry +21.5%; Costco -12.5%; Target -25.9%); Walmart trades at a forward P/E of ~40.3 versus the industry 36.5 (Costco ~41.8, Target ~12.7), and Zacks' consensus implies roughly 4.5% sales and 4.8% EPS growth for the year with a Zacks Rank of #3 (Hold).

Analysis

Walmart's U.S. business reported a 4.5% comparable-sales gain in Q3 FY2026 driven by increases in transactions and unit volumes, with traffic gains both in stores and online and comps positive in each month of the quarter, indicating steady underlying demand rather than a one-off promotional spike. Management highlighted broad-based market share gains across income cohorts — continued frequency from upper-income households and steadiness among middle-income shoppers — while acknowledging lower-income consumer pressure that Walmart's value positioning helped offset. Faster fulfillment and convenience initiatives materially contributed to the transaction growth mix, with a growing share of digital orders delivered within three hours and management expressing confidence these capabilities will support sustained U.S. comp growth into fiscal 2026. The shares have outperformed the industry over the past year (+22.4% vs. industry +21.5%) even as valuation is elevated: forward P/E of ~40.3 versus industry 36.5 (Costco ~41.8, Target ~12.7); Zacks consensus implies roughly 4.5% sales and 4.8% EPS growth and assigns a Zacks Rank #3 (Hold), suggesting limited upside absent accelerating fundamentals or margin improvement.

Key Decisions for Investors

• Maintain a constructive but neutral stance on WMT exposure given transaction-led comp strength and omnichannel execution, but require consistent margin/earnings beats to justify the current premium valuation
• Monitor monthly U.S. comp trends, digital order three-hour fulfillment share and gross-margin guidance closely and be prepared to trim exposure if comps or margin indicators decelerate
• Consider relative allocation decisions versus COST and TGT only after reviewing each peer's operational outlook and valuation divergence noted in the article, using Walmart as a lower-risk, steady-growth option rather than a deep-value retail play
