TSMC packaging shift could boost AMD CoWoS share and trim Nvidia's allocation

The reallocation of TSMC's advanced packaging capacity is poised to reshape the AI chip competitive landscape. As demand for proxy AI processors surges, the allocation of production resources is shifting toward CoWoS, thereby undermining NVIDIA's dominance in high-end packaging. AMD, leveraging its CoWoS capabilities, is expected to gain significant market share by 2027. This shift reflects a broader reassessment of supply chain strategies amid geopolitical fragmentation, especially in the context of U.S.-China tech decoupling. NVIDIA risks customer attrition if it fails to adapt its strategic partnerships. Historically, shifts in packaging technology have triggered industrial restructuring; this move may prompt further strategic realignments among foundries and chipmakers. Over the next 12 months, market dynamics will center on capacity allocation, standardization, and customer retention, establishing new competitive barriers.
