Amazon launched Amazon Supply Chain Services to open its logistics and fulfillment network to all businesses.
The service bundles freight, distribution, and parcel shipping for companies regardless of whether they sell on Amazon's platform.
This strategic initiative mirrors the launch of Amazon Web Services (AWS) by turning internal infrastructure into a public-facing business.
The move directly challenges logistics incumbents FedEx and UPS.
FedEx shares fell as much as 7.4% on the day of the announcement. UPS shares dropped 8.9% following the news.
