Amazon announced its Supply Chain Services platform, opening its trailers, intermodal containers and air cargo capacity to third-party shippers. This service integrates with its fulfillment centers, distribution hubs and last-mile delivery network, extending capabilities previously reserved for Fulfillment by Amazon users.

Following the announcement, transportation stocks plunged, with C.H. Robinson shares down nearly 10%, RXO off about 10%, GXO Logistics dropping 18%, Forward Air falling 24%, FedEx down 9% and UPS tumbling 10.5%. Investors reacted to potential increased competition and margin pressure from Amazon’s expanded logistics offering.

Analysts argue the expansion improves utilisation of Amazon’s excess logistics capacity but does not signal a fundamental shift in its capabilities. The platform is viewed as targeting cost-sensitive customers by monetizing spare capacity rather than directly competing with premium logistics providers.
