2025 年四大 AI 芯片设计公司消耗全球约 90% 的先进封装和 HBM 供应，这些关键输入已成为行业瓶颈。AI 几乎垄断了全球先进芯片封装与高带宽内存产能。
How much of the world's advanced chip packaging and high-bandwidth memory does AI consume？ Almost all of it.
We estimate the four largest AI chip designers consumed ~90% of global advanced packaging and HBM supply in 2025， suggesting these inputs were bottlenecks in 2025.
