What happened?
Amazon announced that 2026 Prime Day will take place from June 23 to 26. The change is intended to give the company an earlier promotional window than its competitors. According to Emarketer, Amazon’s U.S. e-commerce sales are expected to grow 7.1% during the period, with market share projected to reach 60.3%. The company is also actively deploying next-generation Proteus robots at European logistics centers to handle peak-season logistics pressure.
What does this mean for cross-border sellers?
Complete inventory preparation and advertising plans 4–6 weeks in advance. Sellers should closely monitor delivery performance and inventory turnover during the event. Because competitors may follow with their own promotions, sellers should plan differentiated marketing strategies ahead of the traffic peak.
