Amazon has partnered with FedEx to fill some delivery gaps left by UPS, after UPS announced earlier in 2025 that it would significantly reduce deliveries for Amazon, reports Business Insider.

FedEx had severed its relationship with Amazon in 2019 because of rising competition between the two companies.

Business Insider said May 12 it had seen an internal document that indicated Amazon had signed a new partnership deal with FedEx in late February to handle some parts of its package deliveries.

The FedEx deal gives Amazon "cost favorability" compared with UPS, the document said, suggesting the e-commerce behemoth will save money from the transition, but didn't specify the extent of the deal, or which Amazon packages would be handled by FedEx.

"Securing FedEx capacity is our primary solution for these capacity constraints," the internal document said.
