Amazon is planning a major expansion of its sub-same-day delivery network: from fewer than 100 stations today to more than 1,000 by 2031, with roughly 80% of Prime members expected to live within 10 miles of one. The company forecasts the stations will handle about 28% of company-fulfilled volume by 2029 and half of transactions by 2035.

The buildout is expected to prioritize technology and proximity to customers, with many—possibly most—new stations using repurposed properties instead of purpose-built warehouses.

Large new industrial buildings, around 300,000 square feet, remain a common format; in Jacksonville, Amazon upgraded a 272,000-square-foot building with $16.6 million in improvements and later spent another $12 million to add refrigerated space for groceries and perishables.

But Amazon is also exploring smaller and unconventional sites, where being close to customers can matter more than a building’s size. Its planned Orbital modular warehouse technology is designed to handle about 75,000 same-day units in 100,000 square feet and can be arranged in different types of spaces.

Examples include a 15,000-square-foot former Bartell Drugs site in Seattle used for Amazon Flex and a proposed 5,700-square-foot site in North White Plains, New York, for Amazon Now grocery and household deliveries within 30 minutes.

Vacant Amazon Fresh stores could also be converted into delivery stations: after Amazon closed its Fresh grocery division in January 2026, it remained responsible for long-term leases on many locations, whose grocery-ready layouts and customer-facing sites could make conversion practical.

Amazon is testing another approach inside existing Whole Foods stores: a 10,000-square-foot automated center in Plymouth Meeting, Pennsylvania, holds 12,000 items not displayed on shelves, which shoppers can order in-store and often collect within 10 minutes.

A planned 230,000-square-foot big-box store in the Chicago area could combine conventional retail with a sub-same-day delivery station, reflecting a broader trend that includes retailers such as Costco incorporating or expanding delivery operations in store developments.

Walmart is pursuing neighborhood-scale delivery hubs as well, often in former drugstores; its closed-to-the-public Depots typically span 15,000 to 20,000 square feet and let drivers pick up high-demand goods for nearby deliveries, often within 30 minutes.
