Amazon launches 1-hour shipping in US cities to challenge Walmart - Reuters

Amazon has launched one-hour shipping service in select US cities, directly competing with Walmart's rapid delivery capabilities. The move represents an escalation in the retail speed wars, as both e-commerce and traditional retailers race to offer faster fulfillment to consumers. By narrowing delivery windows to a single hour, Amazon aims to strengthen customer loyalty and capture more same-day purchase demand. This service expands Amazon's existing fast-delivery infrastructure, which has become a key differentiator in retail competition. The expansion signals how critical last-mile speed has become to winning market share in the broader retail sector.
