Amazon is gaining ground in the U.S. grocery war

Amazon is gaining grocery market share in the U.S., with Numerator data showing it posted the largest increase over the 12 months ended June 30. The article suggests Amazon’s hybrid grocery strategy—combining online grocery, Amazon Fresh delivery, Whole Foods Market, and local partners—is beginning to pay off as it expands same-day grocery delivery to more cities. This supports Amazon’s broader retail ecosystem and could reinforce customer frequency and spending in everyday essentials. The report also notes that competitors such as Costco and Walmart gained share, while Kroger, Albertsons, Sam’s Club, and Ahold Delhaize USA lost share over the same period. Amazon’s planned closure of some Amazon Fresh and Amazon Go stores, with conversions into Whole Foods locations, signals continued optimization of its grocery footprint.
