Amazon AWS has increased its third-quarter 2026 ASIC server shipment forecast by 20% to 30% from its original plan, signaling stronger confidence in demand for systems built around its Trainium3 artificial intelligence chip. Server motherboards and other components for Trainium3-based systems began shipping in May, adding a fresh supply-chain datapoint that suggests the program is moving ahead. The development also shifts attention to whether AWS will speed up work on Trainium4, which the industry is now watching closely.
