South Korea Commits $518B HBM & Packaging Capacity Supercycle; Nvidia China Revenue Under Structural Pressure from Huawei
Samsung Electronics and SK Hynix have jointly committed 800 trillion won (~$518B) to construct two new chip fabrication sites each in South Korea's southwest region, with an additional 81 trillion won earmarked for an advanced chip packaging cluster in the Chungcheong area — representing the largest single sovereign-backed capacity expansion commitment in HBM and advanced packaging history. Concurrently, AP News reports Nvidia's AI chip sales in China are stalling as Huawei captures domestic share, introducing a structural demand-mix risk that could compress Nvidia's addressable volume for H200/B100-class SKUs in the world's second-largest AI market.
The South Korean mega-investment signals that both Samsung and SK Hynix are racing to lock in long-term HBM and CoWoS-equivalent packaging supply ahead of projected 2027-2028 AI infrastructure peaks — if executed on schedule, this could meaningfully relieve the CoWoS and HBM supply bottlenecks that have sustained elevated BOM costs for H200/B100 integrators since 2024. However, the China displacement signal is a countervailing demand-side risk: if Huawei continues to consolidate China's AI accelerator market, Nvidia's effective volume throughput for premium HBM3e-equipped SKUs may shrink, reducing the demand floor that currently justifies HBM spot premiums.
