The U.S. Supreme Court unanimously invalidated sweeping tariffs on billions of dollars of Chinese imports imposed during the previous administration. The ruling removes a significant layer of import duties that had increased costs for e-commerce companies sourcing goods from overseas.

Following the decision, Amazon and eBay shares climbed as investors anticipated lower procurement costs and wider profit margins. The broader online retail sector also saw gains, signaling confidence in the industry’s ability to pass savings to customers and expand market share.
