Walmart’s Next Chapter: AI and Supply Chain Innovation

Last week, Doug McMillon confirmed his plans to step down as President and CEO of Walmart (effective 31 January 2026), marking a new chapter for the retailer as it continues to modernise operations, invest in digital innovation and transform its global supply chain.

Doug led Walmart through a decade of change, positioning the company as a more agile, tech-enabled business. He has overseen a broad digital shift that includes ecommerce expansion, the integration of AI and a rethinking of logistics and fulfilment processes.

The man set to take over from Doug on 1 February 2026 is John Furner, who currently serves as President and CEO of Walmart US. John has been appointed to the Board of Directors with immediate effect, according to a statement from Walmart.

A shift in leadership

John has been with Walmart since since 1993, rising through the ranks in merchandising, sourcing and operations.

Walmart notes his focus on "associate development, digital innovation and operational excellence" as central to his leadership style. Since 2019, he has led Walmart US, the company’s largest business segment with more than 4,600 stores.

Doug stated: “Serving as Walmart’s CEO has been a great honour and I’m thankful to our Board and the Walton family for the opportunity. I’m incredibly proud of what our associates accomplished and deeply grateful for their commitment to our customers, to each other and the communities we serve.”

To support the handover, Doug will remain on the Board of Directors until the next annual shareholders’ meeting.

Walmart Chairman Greg Penner credits Doug with delivering “a comprehensive transformation by investing in our associates, advancing our digital and ecommerce capabilities and modernising our supply chain resulting in sustained, robust financial performance". 

AI-led transformation continues

Doug’s tenure coincides with Walmart's push to integrate AI into core business functions.

In October 2025, the retailer announced a partnership with OpenAI, led by Sam Altman, to create “AI-first shopping experiences”. The move enables customers to interact with Walmart using ChatGPT, aiming to deliver "personalised, contextual and multi-media interactions" beyond standard ecommerce features.

Doug said at the time that the traditional model of online shopping is shifting: “The search bar and long list of item responses is about to change as Walmart works towards a more enjoyable and convenient future.”

Walmart has spent more than five years developing AI tools not just for customers, but for its internal operations. A report published in August states that these innovations are designed “not just for scale but for people,” highlighting investments in training, pay and new career pathways.

Doug addressed the internal impact in a conversation with the Associated Press, saying: “I think for the most part, our folks are enthusiastic about it [AI] because they’ve seen new tools that they’re receiving that are making their jobs better.”

AI remains a clear focus for the company’s future.

On his successor, Doug added: "His curiosity and digital acumen combined with a deep commitment to our people and culture will enable him to take us to the next level. He’s uniquely capable of leading the company through this next AI-driven transformation.”

Building tomorrow's supply chain

Walmart continues to rework its supply chain to be faster, smarter and more responsive to customer needs.

In May 2024, the retailer opened a high-tech consolidation centre in Minooka, Illinois. The 492,000 square-foot site uses automation to handle three times more volume than a traditional facility, helping to ensure products are available in stores when demand spikes.

This site is the third of its kind and part of Walmart’s broader supply chain network modernisation plan. The programme uses data and emerging technologies to improve visibility and streamline product flow across all regions.

By July 2025, Walmart had extended AI use to its distribution centres. Automated Defect Detection Systems scan millions of packages for damages and barcode issues in real-time. These AI ‘super agents’ are designed to remove bottlenecks and maintain product integrity across the network.

Greg summarised Doug’s legacy by saying he “leaves Walmart stronger, more innovative and better aligned with our purpose to help save people money and live better". 

As John steps into the CEO role, the company’s focus on building a responsive, tech-enabled supply chain remains unchanged. The leadership transition signals Walmart’s intention to stay ahead in retail logistics while continuing to shape new ways for technology and people to work together.
