What Automation is Changing for Walmart's Suppliers

Walmart has become the first major retailer to reach a US$1tn market capitalisation.

This achievement comes as the company continues to invest heavily in supply chain automation and digital infrastructure, which are delivering measurable cost savings and operational efficiency improvements across its network.

The retailer's Q3 FY26 earnings release revealed US$179.5bn in revenue alongside 27% growth in ecommerce.

According to Walmart, these results reflect consistent cost savings that can be attributed directly to its supply chain investments.

The company has reached a point where more than 60% of Walmart US stores now accept freight from automated distribution centres, while over 50% of its ecommerce fulfilment volume has been automated.

“That translates into lower shipping costs,” says Walmart EVP and CFO John David Rainey.

“Our shipping costs have been down consistently for many quarters in the 30% range.

"This was another quarter where we saw double-digit improvements, and that really helps our e-commerce economics, but also helps the overall SG&A of the company.”

Modernising fulfilment networks

Walmart has been actively deploying automated technology across both perishable and non-perishable distribution networks.

According to the company, the most significant productivity gains are occurring within its fulfilment centres, where a transition that began in 2022 continues to accelerate.

“They’re about twice as productive as a legacy fulfilment centre,” explains David Guggina, EVP and Walmart US Chief eCommerce Officer.

“And they’re becoming more and more capable over time as we continue to bring more and more robotics into the different processes.”

The retailer is modernising operations through the deployment of autonomous forklifts, inventory-tracking sensors and high-density storage systems.

Much of this regional distribution centre automation has been driven by an ongoing deployment of AI-enabled robotics from automation vendor Symbotic.

Changing supplier requirements

Walmart's internal automation may fundamentally change how its manufacturing partners operate.

To integrate effectively with the retailer's high-speed automated distribution centres, suppliers and manufacturers must now adhere to increasingly strict fulfilment and packaging standards.

Under compliance frameworks such as the Supplier Quality Excellence Program (SQEP), manufacturers are required to modernise their own end-of-line operations.

This includes standardising barcode formats such as GS1-128, using specific Grade A pallets and right-sizing case packaging so goods can be seamlessly ingested and scanned by Walmart's robotic sorters and autonomous systems without manual intervention.

Additionally, Walmart has been utilising automation at the procurement level.

The company has deployed AI-powered negotiation software to manage contracts with its manufacturers.

This system automates pricing discussions, delivery windows and volume commitments, which aim to streamline supplier interactions while reducing procurement costs.

The Louisiana facility upgrade

As part of a broader initiative to upgrade all 42 of its regional distribution centres, Walmart is investing more than US$330m in its Opelousas, Louisiana facility.

The project, which is slated to begin this year, aims to double the site's shipping capacity through robotics and automation.

According to Walmart, the technology is intended to upskill and support the facility's existing workforce, rather than replace it.

More than 1,900 of Walmart's 37,400 Louisiana employees work in distribution.

A Walmart spokesperson said: “This will play a strategic role in supporting our goal of modernising our vast supply chain network by increasing the speed, efficiency and safety at which products are distributed across our regional distribution centres." 

By automating repetitive warehouse tasks, Walmart has maintained a stable global workforce of approximately 2.1 million while scaling to meet consumer demand.

The retailer now offers same-day delivery to 95% of US households.

According to the company, store-fulfilled deliveries increased by nearly 50% in Q3, with approximately 35% of those orders delivered in under three hours.

Moving forward, Walmart continues to merge its physical footprint with digital commerce and logistics, using real-time visibility and AI-driven automation to operate less like a traditional retailer and more as an omnichannel platform.
