The news: Walmart Inc. reshuffled its leadership ranks ahead of its CEO transition.

• Walmart US ecommerce head David Guggina will take over as president and CEO of the entire division on February 1.
• The retailer also announced new leadership for Sam’s Club and Walmart International, along with the promotion of Walmart US chief growth officer Seth Dallaire to the same role at Walmart Inc.

What it means: Walmart’s decision to elevate the head of its US ecommerce business to the top division role is a clear sign of the company’s priorities in 2026 and beyond. The retailer is making bold bets on agentic commerce—including a new partnership with Google to make its products discoverable and purchasable via Gemini—while continuing to invest in fundamentals like its supply chain to drive greater efficiency and improve execution.

While it may take time for Walmart’s agentic efforts to fully gain traction with shoppers, its ecommerce business is poised for another year of healthy growth.

• Walmart’s digital sales are growing significantly faster than overall sales, thanks to investments in automation and delivery speed, rising adoption of its Walmart+ membership program, and its increasingly lucrative retail media business.
