Heavy U.S. tariffs on Chinese imports are reshaping the retail landscape, and scale is emerging as a decisive advantage. Walmart, Amazon and T.J. Maxx owner TJX are gaining market share by keeping prices low and offering faster delivery, according to industry data and company commentary. Their performance underscores that shoppers remain willing to spend when they perceive value and convenience despite broader economic uncertainty. Walmart has absorbed much of the tariff-driven cost inflation, enabling the world’s largest retailer to post a 4.5% gain in U.S. same-store sales during the first half of 2025 and to lift its full-year outlook. Chief Executive Officer Doug McMillon said investments in artificial intelligence and supply-chain automation are boosting productivity, while Chief Financial Officer John David Rainey signalled the company still sees “many opportunities to invest a dollar for high returns.” Former Walmart U.S. chief Bill Simon called the latest quarter “about as good as any retailer could have in any environment.” Amazon has expanded its delivery network to preserve two-day and same-day shipping, cushioning shoppers from higher import costs, while TJX has turned excess inventory from struggling chains into bargains that continue to draw traffic to T.J. Maxx and Marshalls stores. Both companies report that value-oriented assortments are resonating with consumers facing higher everyday prices. Not all big-box chains are faring as well. Target’s shares are down roughly 40% this year as the company wrestles with softer in-store traffic and inventory missteps, and BJ’s Wholesale Club on Friday reported a 0.3% drop in comparable-club sales, sending its stock 8% lower. BJ’s Chief Executive Officer Bob Eddy said customers across income levels are showing signs of stress, and the chain pledged to hold prices “as long as we can.” Analysts warn that retailers without pricing power or logistical scale face mounting pressure as the 145% tariff on Chinese goods flows through supply chains.
