Amazon’s same-day grocery delivery service has emerged as a key driver of parcel traffic across the United States, with internal operational metrics indicating a 37% rise in delivery volume during the November–December 2025 holiday window compared to the prior year. This surge is concentrated in urban centers such as New York City, Chicago, and Los Angeles, where over 1.8 million grocery deliveries were fulfilled within 24 hours in December alone. The service, now available in more than 80 metropolitan areas, functions as a high-density delivery magnet, enabling Amazon to consolidate last-mile logistics and optimize vehicle routes. By bundling grocery orders with other small parcels, the company has reduced average delivery costs per unit by 14% in participating zones, according to internal efficiency reports. Third-party sellers and retailers have responded by increasing their reliance on Amazon’s logistics infrastructure. Over 42,000 small and medium-sized vendors signed up for the same-day delivery network in 2025, up from 28,000 in 2024, citing faster fulfillment times and higher customer retention as key incentives. This growing ecosystem has also prompted regional warehouse expansions, including two new fulfillment centers in Dallas and Atlanta, each capable of handling 250,000 daily shipments. The impact extends beyond Amazon’s direct operations. Local delivery fleets and contract logistics providers have reported a 29% increase in contract work, particularly in delivery driver staffing and electric delivery van procurement. The service’s success underscores a broader industry shift toward hyper-local delivery models, with competitors like Walmart and Instacart accelerating similar initiatives in response.
