Amazon Threatens to Sever $6 Billion USPS Tie, Accelerating Shift to Private Delivery Dominance

E-commerce giant Amazon is exploring a major strategic pivot that could see it terminate its decades-long partnership with the U.S. Postal Service (USPS), potentially dealing a significant financial blow to the government agency.

The move is driven by the breakdown of contract talks regarding the “negotiated service agreements” that govern Amazon’s package delivery, which is set to expire in October 2026. Amazon was reportedly surprised by the USPS’s decision to phase out these individualized contracts in favor of a new, competitive, auction-style bidding system for access to its parcel capacity. The goal of the new system is to “democratize” access for smaller shippers, but it removes the sweetheart deal currently enjoyed by large customers like Amazon.

For the USPS, losing Amazon’s business would be catastrophic. The company is the agency’s top customer, contributing over $6 billion in annual revenue in 2025, which accounts for approximately 7.5% of the USPS’s total yearly income. The Postal Service is already facing financial challenges, having posted a $9.5 billion loss in the last fiscal year, and it relies heavily on parcel revenue to maintain its universal service mandate, particularly in expensive rural areas.

In response to the uncertainty, Amazon is actively planning to fully leverage its massive internal infrastructure, Amazon Logistics, by pulling the billions of packages it currently routes through the USPS. The company has spent billions expanding its proprietary network of planes, fulfillment centers, and delivery vans.

This expansion has brought Amazon to the brink of parity with the government carrier. Industry data from 2024 highlights the rapidly closing gap, illustrating Amazon’s confidence in its ability to become almost entirely self-reliant in package delivery.
