> Walmart's Q2 showed e-commerce sales up 24% and now over 23% of U.S. segment sales. For operators, the question is how fast stores become fulfillment nodes without breaking labor and inventory systems.

## Key points

- Walmart's e-commerce sales have grown by 24% and now make up over 23% of Walmart U.S. segment sales.
- Walmart U.S. comp sales grew 2.6% in Q2, or 3.4% excluding health and wellness, with softness attributed to drug pricing regulation.
- Stores face the challenge of becoming fulfillment centers without disrupting labor and inventory management.

Walmart’s latest quarter put a hard number on a shift most retail operators have been feeling for two years: stores are still the backbone, but digital demand is now big enough to dictate how those stores are run.

On its fiscal 2027 second-quarter earnings call, CFO John David Rainey said Walmart U.S. e-commerce sales grew 24% year over year and now represent over 23% of the segment’s sales mix, according to Retail Dive’s reporting on Aug. 20. Walmart’s own earnings materials also show the company growing total revenue 5.9% year over year to $187.9 billion, with operating income up 28.8% to $9.4 billion.

The Wall Street Journal, also on Aug. 20, framed the same quarter more bluntly: Walmart’s sales lift is increasingly coming from e-commerce, membership, and advertising, not from the physical stores themselves. For VPs of operations and supply chain leaders, that is less a narrative shift than an execution requirement. A 23% digital mix changes the store from a selling floor with a back room into a mixed-use facility with pick paths, staging lanes, and new failure modes.

## E-commerce mix is turning stores into production sites

Retail Dive reported that Walmart’s transactions and average ticket each grew more than 1% year over year in Walmart U.S. in the quarter. That’s a crucial detail for operators: digital growth isn’t only cannibalizing store volume, it’s adding work on top of already-high traffic in many locations.

Rainey said the online mix is “double what it was from five years ago,” per Retail Dive. That five-year doubling rate is a workable benchmark for other large-format retailers trying to plan store labor and fixture changes on a realistic cadence. Remodel cycles, WMS refreshes, and handheld device replacements are slower than digital growth. When e-commerce crosses the 20% threshold, many chains find they can’t keep treating picking as a seasonal overlay.

> Once online is a quarter of sales, the store stops being a channel and starts being a capacity constraint.

The WSJ’s emphasis on membership and advertising as growth engines adds another operational layer. If digital monetization is increasingly happening through membership fees and retail media, then stores end up carrying the service-level obligations that keep those flywheels spinning: high in-stock rates, dependable substitutions, predictable pickup windows, and fewer canceled orders. Those aren’t “digital KPIs.” They’re store discipline and inventory accuracy, measured at aisle level.

## Comps were also a pharmacy story, and that changes labor math

Walmart disclosed that Walmart U.S. comp sales grew 2.6% in Q2, but the company attributed softness to maximum fair price regulation on drugs, Retail Dive reported. In the same earnings materials, Walmart said comps were 3.4% excluding health and wellness.

That 80-basis-point spread matters because health and wellness is both traffic-driving and operationally specialized. If comp performance can move materially based on drug pricing policy, pharmacy labor, appointment capacity, and front-end workflow design become part of the comp plan, not a separate clinical add-on. For operators with embedded clinics, immunization programs, or high-Rx stores, the quarter is a reminder that regulatory changes can land as a store-execution problem quickly.

## What Walmart’s quarter implies for suppliers and retail ops roadmaps

Walmart raised its fiscal 2027 net sales guidance to 4% to 5%, up from 3.5% to 4.5%, according to Retail Dive’s reading of Walmart’s guidance update. The company-level numbers underline something procurement and supply chain teams already know: demand is holding, but the way demand arrives is less predictable by store and daypart.

For CPG suppliers, the e-commerce share has packaging, case-pack, and replenishment consequences. A higher online mix often increases the share of eaches and break-pack activity, whether it happens in a DC, a micro-fulfillment environment, or the store back room. If a retailer is doing more store-based picking, on-shelf availability and backroom location discipline become the supplier’s service-level issue too, because out-of-stocks get surfaced immediately as canceled or substituted online orders.

For retailers, the quarter suggests a more specific governance question: where does omnichannel labor live? When growth is being driven by e-commerce, membership, and advertising, as the WSJ reported, store leaders can end up absorbing new tasks while P&L benefits accrue to other lines. That gap tends to show up as inconsistent pickup performance, inventory record errors, and higher shrink risk unless incentives and staffing models are rebalanced.

> Retail media can fund the future, but it doesn’t pick the order.

## Questions to put into store standards and supplier scorecards this quarter

- At what e-commerce mix does the chain shift from ad hoc picking to scheduled picking blocks, and how is that threshold defined (sales mix, order volume, or labor hours)? Walmart’s 23%+ mix is a concrete reference point, per Retail Dive.
- Do pharmacy and health services have a separate comp sensitivity model in store planning? Walmart reported 2.6% comps versus 3.4% excluding health and wellness, per Retail Dive, which is a usable way to isolate how category policy changes can swing results.
- Are suppliers being measured on shelf-level availability and pick accuracy outcomes, or only on DC fill rate? A store-fulfilled model makes in-store execution part of the service-level contract even when the supplier ships casepacks to a DC.
- If membership and advertising are major growth drivers, as the WSJ reported, what operational KPIs are treated as non-negotiable to protect those businesses (pickup on-time rate, cancellation rate, substitution rate), and who owns them day to day?
