How Automation is Powering Walmart's Cost Savings

As procurement and supply chain leaders seek to drive operational efficiency and reduce costs, Walmart's automation strategy demonstrates how strategic investment in distribution technology can deliver significant financial returns.

Walmart's automation journey offers procurement professionals a compelling case study in how technology investment can transform both operations and bottom-line performance.

Since beginning its automation rollout, Walmart has reached a US$1tn valuation, becoming the first major retailer to achieve this market capitalisation. This milestone demonstrates the procurement and supply chain benefits of next−generation technological implementation.

The company plans to invest US$330m to modernise its regional distribution centre in Opelousas, Louisiana, with the goal of doubling shipping capacity through automation deployment.

Procurement's role in automation

In Walmart's Q3 2025/26 earnings release, the retailer reports growth across sales and revenue, including ecommerce growth of 27% and revenue of US$179.5bn for the third quarter. For procurement leaders, the consistent cost savings represent a key outcome of strategic supplier and technology investment decisions.

The retailer's strategy for offering low prices and greater convenience includes leveraging physical and digital assets. Through repeated procurement investments in supply chain automation, Walmart is seeing improved efficiency across operations.

More than 60% of Walmart US stores accept freight from automated distribution centres and more than 50% of its ecommerce fulfilment centre volume is automated. According to the company, this has resulted in greater unit productivity across distribution networks.

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

"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 ecommerce economics, but also helps the overall selling, general and administrative expenses (SG&A) of the company."

For procurement teams evaluating automation, suppliers and solutions, these figures indicate the potential return on investment from distribution centre technology.

Sourcing fulfilment technology

Automated technology is being deployed across perishable and non-perishable distribution networks, but fulfilment centres are undergoing the most significant productivity transformation.

Procurement decisions around automated fulfilment centre suppliers are proving central to this shift, with many new facilities entering Walmart's supply chain.

"They're about twice as productive as a legacy fulfilment centre," says 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 launch of Walmart's next-generation fulfilment centres began in 2022, with plans to expand automated centres further. Procurement of automation solutions has been a key focus in recent years, including sourcing autonomous forklifts, inventory-tracking sensors and high-density storage systems from technology suppliers.

Strategic procurement outcomes

Walmart has seen substantial benefits from this automation transformation, with a share price exceeding US$126. Its growing ecommerce operations and ability to offer same-day delivery to 95% of US households demonstrates how procurement-led technology investment can enable customer service improvements.

This is aided by ongoing procurement and deployment of warehouse automation solutions, supported by a stable global workforce of approximately 2.1 million. In Q3, there was an increase of almost 50% in store-fulfilled delivery, with approximately 35% of store-fulfilled orders delivered in less than three hours.

Through procuring automation for repetitive tasks, Walmart is ensuring its workforce can focus on other areas without spending time and resources training new staff to meet consumer demand.

As part of its push to modernise all 42 regional distribution centres, Walmart is preparing to invest more than US$330m in its Opelousas distribution centre. By procuring and introducing robotics and automation solutions, Walmart plans to double the facility's shipping capacity, with the project beginning in 2026.

A Walmart spokesperson says: "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."

With revenue growth, cost savings and increased efficiency, Walmart is demonstrating how procurement leaders can drive automation implementation and digitalisation for operational gain.
