Amazon Plans More Than 1,000 Same-Day Hubs to Close Walmart Gap

Amazon is planning to build more than 1,000 same-day fulfillment hubs across the United States, a logistics expansion that Bank of America analysts say is designed to close the proximity gap that has long given Walmart a structural edge in rapid delivery, according to a Bank of America research note cited by Business Insider.

Walmart's advantage in same-day and next-day delivery has historically rested on its network of more than 4,600 US stores, which function as de facto distribution points within a short distance of most American consumers. That physical density has allowed Walmart to fulfill online orders quickly without building dedicated e-commerce infrastructure at comparable scale.

Bank of America analysts described Amazon's same-day delivery service as "very important strategically" in the note reviewed by Business Insider. The analysts said faster delivery combined with automation could extend Amazon's retail-margin gains, though they did not specify a timeline or a projected margin improvement figure in the publicly available summary of the note.

Amazon has not filed a capital expenditure breakdown specifically for the hub expansion in a public SEC filing available as of September 17, 2026. The precise cost of constructing more than 1,000 facilities, the rollout schedule, and the target markets for initial deployment are not disclosed in the source material. Those details would be revealed through Amazon's quarterly earnings reports or future SEC filings.

The hub plan represents a continuation of Amazon's multiyear investment in last-mile logistics infrastructure. Amazon disclosed in prior annual reports that it has been building out its own delivery network, including Amazon Logistics, to reduce dependence on United Parcel Service and FedEx. The same-day hub initiative extends that strategy toward the fulfillment stage rather than just the delivery stage.

Automation is central to the Bank of America analysis. The analysts noted that automated fulfillment processes within the hubs could improve per-unit economics for Amazon, which has faced margin pressure in its retail segment relative to its higher-margin Amazon Web Services division. Amazon's retail operating income and AWS operating income are reported separately in its quarterly earnings filings with the SEC.

For consumers, the buildout is intended to increase the share of US addresses that can receive same-day delivery on eligible items. Amazon's same-day delivery service is currently available in select metro areas. The 1,000-hub target would, if completed, meaningfully expand that geographic footprint, though the company has not publicly stated what percentage of US households it aims to reach.

For Walmart, the competitive pressure is arriving as the company is also investing in its own e-commerce and delivery infrastructure. Walmart has reported e-commerce sales growth in recent quarterly earnings releases and has expanded its Walmart Plus membership program, which includes same-day delivery benefits, as a direct competitive response to Amazon Prime.

The broader market context for both companies includes a period of elevated interest rates following the Federal Reserve's rate increase earlier this week, which raised the cost of capital for large infrastructure investments. Higher borrowing costs could affect the pace at which Amazon finances and deploys the hub network, though Amazon has not commented publicly on that connection as of this reporting.

Bank of America's characterization of the hub plan as strategically significant reflects a view shared by multiple analysts that last-mile delivery speed has become a primary competitive variable in US e-commerce. Whether Amazon's hub expansion translates into measurable market-share gains from Walmart will depend on execution timelines and consumer adoption rates, neither of which can be confirmed from currently available public disclosures.
