Amazon is reportedly preparing a major logistics shift that could reduce the share of packages it sends through the U.S. Postal Service by at least two-thirds by fall 2026. If executed at that scale, the move would deepen Amazon’s push into in-house delivery and reshape one of the biggest relationships in U.S. parcel shipping.
What the Report Says
According to reporting from The Wall Street Journal, Amazon has been signaling plans to materially reduce USPS package volume as contract and bidding dynamics evolve in 2026. Multiple market summaries of the report point to a reduction target of roughly two-thirds, with timing tied to the fall season.
That would be a significant volume reset for USPS, which has handled a large portion of Amazon’s parcel traffic in recent years, especially on costlier routes.
Why Amazon Is Making This Shift
The strategic logic is straightforward: tighter control over last-mile delivery, better route optimization, and improved economics over time. Amazon has steadily expanded its own fulfillment and delivery network, and cutting dependence on external carriers fits that long-term model.
This also gives Amazon more flexibility during peak seasons, when service reliability and delivery speed directly impact customer retention.

A large drawdown from a customer as big as Amazon could pressure USPS package volume and revenue mix, at least in the near term. USPS has invested heavily in network modernization and parcel capacity, so a sudden change in large-shipper flow can affect utilization and operating leverage.
The agency may need to replace lost volume with other shippers, reprice contracts, or rebalance network planning to protect margins.
