$Broadcom(AVGO)$ Broadcom's AI accelerator project for ByteDance has been canceled amid tightening U.S. semiconductor restrictions on China, leading to a $2-3 billion loss. Stricter controls on HBM-based AI chips have contributed to a broader decline in CoWoS advanced packaging orders from Chinese firms. T-Head and Sanechip have also reduced or halted CoWoS shipments, signaling further disruptions in the Chinese semiconductor market.
