Walmart’s Automation Push Raises a Big Question: Is Faster Cheaper?

Article

Walmart has opened a highly automated fulfillment center in Stockton, California, as recent reports highlight operational challenges in its automation program. This timing matters, as the freight market now expects automation to handle real volume, enable faster delivery, and process returns across facilities, stores, and transportation networks.

For logistics leaders, the key point is clear: reducing process steps does not guarantee lower landed costs. Automation delivers value only when throughput, uptime, energy, labor, packaging, inventory, and downstream transportation improve together as a unified system.

Walmart Scales Automation—While Working Through the Friction

Walmart’s announcement of its fifth next-generation fulfillment center says the new Stockton operation spans more than 900,000 square feet and is expected to employ more than 1,000 associates. Its automated, high-density storage-and-retrieval system brings products to workers and reduces the traditional fulfillment process from 12 steps to five.

The facility adds capacity closer to West Coast customers and will support both Walmart orders and third-party Marketplace volume through Walmart Fulfillment Services. Walmart also says its next-generation fulfillment centers, combined with the rest of its network, can provide next- or two-day shipping to 95% of the U.S. population.

Walmart’s New Stockton Facility

The operating momentum is already substantial. During Walmart’s fiscal second-quarter 2027 earnings call, CFO John David Rainey said 3,100 U.S. stores receive some level of automated freight, and more than 50% of e-commerce fulfillment volume moves through automated facilities. Walmart U.S. e-commerce grew 24% during the quarter, while store-fulfilled delivery grew more than 40%.

Karisa Sprague, Walmart U.S. senior vice president of fulfillment operations, described Stockton in the company’s facility-opening statement as “people-led and tech-powered,” adding that the system is designed to “create a safer, more efficient operation” that can fulfill more orders faster.

The numbers executives should retain:

• 900,000+ square feet: Stockton’s footprint.
• 1,000+ jobs: Expected employment at the facility.
• 12 steps reduced to five: Walmart’s reported change to the fulfillment process.
• 3,100 stores: U.S. locations receiving some automated freight.
• More than 50%: Share of Walmart’s e-commerce fulfillment volume processed through automated facilities.

Automation Shifts Costs. Does It Lower Cost per Order?

Supermarket News offers a counterpoint by examining Walmart’s automation challenge and summarizing Wall Street Journal reports on equipment failures, retrofit complexity, and increased overhead. Issues include shipping cartons too large for some systems, frequent breakdowns of wheeled robots, oversized products that require manual handling, and the difficulty of installing equipment in operational warehouses built in the 1980s and 1990s.

The cost comparison is the sharpest data point. One automated grocery facility's reported electricity expense can reach $800,000 per month, up from about $250,000 previously. The same reporting says automated sites require specialized engineers who cost more than conventional warehouse labor.

That figure needs discipline. It is an attributed example—not a disclosed Walmart network average—and the reporting does not provide order volume, cases shipped, or cubic throughput for the compared periods. A larger power bill can coexist with better unit economics if the facility moves enough additional volume. Without cost per case, cost per order, and uptime, the utility bill alone cannot establish success or failure.

Walmart’s response captures the tension. In comments included in the Supermarket News report, the company said, “New technology is never perfect on day one,” adding that it is “constantly learning and adjusting.”

A factual correction is also important. The Supermarket News article says Symbotic acquired Alert Innovation from Walmart in 2023. The corporate record shows that Walmart announced its agreement to acquire Alert Innovation in October 2022, while Symbotic completed its acquisition of Walmart’s Advanced Systems and Robotics business in January 2025.

Warehouse Speed Changes the Freight Equation

For freight operators, the strategic issue is not how many robots work inside a warehouse. It is how automation changes freight arriving at the dock, the rhythm of outbound tenders, and the recovery capacity needed when the system stops.

A highly automated building can compress cycle times, but it can also make transport demand less forgiving. Faster internal processing may produce tighter pickup windows, larger release waves,s and higher expectations for trailer availability. Carriers and brokers serving these facilities should weigh appointment accuracy, drop capacity, and exception response more heavily in bids.

Packaging becomes a critical part of operating infrastructure. Cartons suitable for manual warehouses may constrain automated systems if their dimensions, tape, rigidity, or label placement don't meet machine tolerances. Reported issues with oversized boxes and products show how quickly warehouse limitations can affect supplier compliance, packaging procurement, and inbound quality control.

The downstream economics matter just as much. Reporting on Walmart’s distribution-center automation explains that the systems are intended, in part, to build store-ready pallets that are easier to unload and stock. If that design reduces touches at the store, improves shelf availability and shortens trailer dwell, value may appear outside the automated building. Measuring only warehouse headcount would miss it.

Faster warehouses are only part of the equation. The operating challenge is keeping transportation, facility design, and cost measurement in step.

Below are six decisions where greenfield facilities give freight and warehouse operators an advantage, and the metrics that show whether automation is actually paying off.
