Walmart’s Grocery Lead Faces a Higher-Margin Test

Walmart's forthcoming earnings report on August 20 unveils a significant challenge for the retail giant - converting its grocery traffic into higher-margin sales. According to a new PYMNTS Intelligence report, "The Basket Breakaway: How Amazon Is Turning Walmart’s Store Traffic Into a Retail Weakness," the U.S. retail landscape is witnessing a widening gap between Walmart and Amazon, particularly in the grocery category.

While Walmart continues to dominate grocery sales, Amazon has been steadily expanding its reach into other product categories, posing a threat to Walmart's revenue streams. In the first quarter of 2026, Walmart captured 20.8% of U.S. consumer spending on food and beverages, a 17.9 percentage point advantage over Amazon's 2.9%. However, Amazon's growth in overall retail spending (9.3%) outpaced Walmart's (7.8%) during the same period, marking Amazon's largest first-quarter lead since 2024.

The report highlights Walmart's struggle in converting grocery shoppers into buyers of higher-margin products like electronics, furniture, and apparel. Despite Walmart's 10.3% share in "trip" categories and 5.9% in "order" categories, the gap between its two segments has widened by over five times since 2019. Amazon, on the other hand, leads Walmart by significant margins in categories such as sporting and hobby goods, music and books, electronics and appliances, furniture and home furnishings, and clothing and apparel.

Walmart's success hinges on its ability to leverage its existing infrastructure, such as stores, curbside pickup, Walmart+, a growing marketplace, and OnePay financing, to transform routine grocery visits into more profitable relationships. The upcoming earnings call will be closely watched to determine if Walmart can safeguard its grocery lead while expanding its presence in higher-margin categories.
