Amazon is considering ending its partnership with USPS when their contract expires at the end of 2026. This $6B+ annual relationship faces uncertainty as negotiations stall over USPS's proposed "reverse auction" system for shipping capacity.
What's Happening
Talks between Amazon and USPS have stalled over a fundamental disagreement about how shipping capacity should be allocated. USPS wants to implement a "reverse auction" system where carriers bid for delivery contracts. Amazon, which has invested heavily in its own logistics network, is reportedly unwilling to participate in this competitive bidding process.
The current contract expires at the end of 2026. If no agreement is reached, Amazon could walk away from its largest shipping partner, a move that would reshape the entire US package delivery landscape.
Why This Matters
USPS delivers approximately 15% of Amazon packages, with that number reaching 30-40% in rural areas where private carriers don't operate. A breakup would force major changes to delivery infrastructure across the country.

The Core Disagreement
USPS wants to move to a "reverse auction" model where shipping capacity goes to the lowest bidder. This approach could help USPS maximize revenue from its delivery network. Amazon, however, has spent over $100 billion building its own logistics infrastructure and doesn't want to compete on price alone.
According to industry reports, Amazon executives believe their volume and reliability should guarantee preferential treatment, not subject them to auction-style bidding.
Amazon's Logistics Buildout
Amazon has invested heavily in delivery infrastructure since 2018. The company now operates over 1,000 delivery stations across the US, has a fleet of 100,000+ branded vans through its Delivery Service Partner program, and has expanded its air cargo network to 100+ planes.
Impact on Amazon Sellers
FBA Sellers
If USPS exits Amazon's delivery network, FBA sellers could see delivery time changes in specific ZIP codes, particularly rural areas. Amazon would need to either build out its own rural delivery capacity or rely more heavily on UPS and FedEx, both of which charge premium rates for remote deliveries.
Higher delivery costs in rural areas could affect Prime delivery promises and potentially impact profit margins on orders shipped to those regions.
FBM Sellers
Fulfilled by Merchant sellers who use USPS for their own shipping may face indirect effects. If USPS loses Amazon's volume, the postal service might need to raise rates across the board to compensate for lost revenue.
Potential Upside
Some analysts suggest Amazon building out more delivery infrastructure could ultimately benefit sellers through faster, more reliable deliveries. Amazon's own delivery network already handles same-day and next-day deliveries more consistently than third-party carriers.
What Sellers Should Do Now
- Audit your geographic sales distribution: Understand what percentage of your orders ship to rural ZIP codes that rely on USPS. Use your order analytics to identify geographic patterns.
- Monitor delivery performance metrics: track on-time delivery rates by region. Changes in delivery performance could signal network adjustments before any official announcement.
- Consider FBA for high-volume products: FBA gives you access to Amazon's expanding logistics network, insulating you from carrier-specific disruptions.
- Review FBM shipping strategies: If you ship FBM, diversify your carrier mix. Don't rely exclusively on USPS for fulfillment.
