Prime Day spending rises as Walmart faces wider retail pressure

Prime Day has become a floor-level test for Walmart, not just an Amazon sale. Adobe Analytics said U.S. online spending on the first day of Amazon Prime Day reached $8.3 billion, up 5.3% from a year earlier, while Walmart ran Walmart Deals June 22-28 and Amazon's Prime Day ran June 23-26, putting the Bentonville, Arkansas retailer in the same summer promotion window.

For hourly associates, that overlap shows up in practical ways: more customers comparing prices on the app while standing in aisles, more questions about substitutions, more pressure to keep shelves, pickup orders and front-end service lined up with what shoppers saw online. Department managers and assistant managers feel it in pricing execution, replenishment and pickup readiness, because the event is no longer about one retailer pulling traffic away from another. It is about whether Walmart can keep its low-price message credible when shoppers are moving between stores, apps and delivery options in the same trip.

Walmart has leaned into that competition with a model built on low prices, faster delivery, curbside pickup and in-store shopping, and it has said those channels are central to growth. The company also said it was rolling out AI-powered tools, including real-time translation and task management, across 1.5 million U.S. associates. During peak promotion weeks like Prime Day, those tools are meant to help workers keep pace, but the pressure on the floor is still the same: get the price right, keep inventory moving and make the customer experience match the promise on the screen.

The stakes are larger than a single week. Adobe said Prime Day 2025 generated $24.1 billion in online spending across U.S. retailers over the event period, showing how much of the shopping surge now spills beyond Amazon itself. That matters inside Walmart because customers increasingly treat summer discount events as a direct comparison on value, speed and convenience, and a weak price sign or a slow substitution answer can erase the edge of a deal.

Walmart has spent years building its pitch around that competition, using its store network, e-commerce assortment and membership services to keep shoppers inside its ecosystem. This year's overlap between Walmart Deals and Prime Day made that strategy visible on the sales floor, where every price check, pickup handoff and customer-service answer became part of a wider retail stress test.
