Does A Postal Service Backup Plan Materially Alter Amazon’s Cash Outlook?
An internal Amazon (AMZN) document lays out Project Aurelian, a plan for delivering its own packages without the US Postal Service. Management has told investors that most of Amazon’s heavy spending goes to AI and AWS. Is Project Aurelian a new bill for Amazon, or a name for a delivery network it is already paying for?

What Happened
It was reported on October 1 that an internal Amazon document lays out Project Aurelian. The plan is a fallback for life without the US Postal Service. Amazon developed the plan as contract negotiations with the Postal Service became strained. It aims for Amazon’s own delivery service to reach 95% of US ZIP codes. Those ZIP codes account for 99.9% of US demand. To get there, Amazon would add new delivery warehouses and local partnerships, reducing its dependence on outside carriers. The plan bears on North America, Amazon’s largest reported segment.
What Changed
Amazon was already speeding up delivery before the plan surfaced. Globally, Amazon delivered over 40% more items same day or overnight in the first half of 2026 than a year earlier. That speed figure covers Amazon worldwide, not just the US network the plan targets.
Two things are new. First, the reach: Amazon’s own service would cover nearly every US ZIP code. Second, the reason: the network becomes a fallback for life without the Postal Service, not only a way to deliver faster. The details made public put no cost on any of it.
How Big A Business This Impacts
The plan touches North America, Amazon’s largest segment, with $426.3 billion of revenue in fiscal 2025, 59% of the total. That year, North America earned $29.6 billion of operating income, a margin of 6.9%. Management expects about $220 billion of capital spending in 2026, most of it for AI and AWS. Over the past twelve months, capital spending of $173 billion already ran above operating cash flow of $161.4 billion. Any new delivery bill would widen that gap. The delivery plan has no published cost, so nothing yet shows it adding much to that budget.
What Management Has Said
On its second-quarter 2026 earnings call, management said Amazon kept cutting its cost of serving customers as transport got dearer:
- “We continue to lower our overall cost to serve.”
- “We face heightened transportation costs driven by fuel inflation from the conflict in the Middle East and higher line haul rates from driver capacity limitations.”
Amazon’s internal document adds a different motive: management spoke about the cost of delivery, while Project Aurelian aims to reduce Amazon’s reliance on outside carriers, including the Postal Service
What to Watch
- Amazon’s third-quarter 2026 report is expected on or around October 28. A cost for Project Aurelian would be the first figure that sizes the plan.
- Management’s 2026 capital spending estimate stands at about $220 billion. A rise tied to delivery warehouses rather than data centers would show the plan adding to spending.
- Management guided Amazon’s total third-quarter operating income to $22.5 billion to $26.5 billion. A result below that range would leave less money for a new delivery build.
- Amazon’s contract talks with the US Postal Service have been strained. A new agreement would keep Project Aurelian a fallback. A breakdown would make it a network Amazon has to build and fund.
