Samsung and SK Hynix are committing $590 billion to build new chip factories and packaging centers, backed by South Korean government support. The investment targets explosive growth in AI data center demand, particularly for high-bandwidth memory (HBM) chips that power large language models and other compute-intensive workloads.
Memory prices are climbing sharply as AI adoption accelerates. Jefferies projects quarterly price increases of up to 50 percent through 2027, driven by sustained data center expansion. Samsung and SK Hynix control roughly 80 percent of the global HBM market, positioning them to capture significant value from this price surge.
HBM chips represent a bottleneck in AI infrastructure. Unlike standard DRAM, HBM stacks memory vertically on processor packages, delivering the high bandwidth required for training and inference at scale. Nvidia's H100 and newer GPU architectures depend heavily on HBM supply. Shortages in 2024 constrained data center deployments across cloud providers and enterprises.
The $590 billion commitment addresses this constraint directly. The funding covers manufacturing capacity expansion and advanced packaging technologies needed to scale HBM production. South Korea's government backing reflects the country's strategic interest in maintaining semiconductor leadership against competition from Taiwan and the United States.
This investment carries competitive implications. TSMC, the world's largest contract chipmaker, supplies packaging services for advanced chips but does not produce memory. Intel and Micron pursue memory production in the US and Europe, but neither commands SK Hynix and Samsung's scale or manufacturing expertise in HBM specifically.
The price surge benefits memory suppliers in the near term but risks demand destruction if costs become prohibitive for smaller AI companies and startups. The investment timeline extends through 2027, suggesting Samsung and SK Hynix expect sustained HBM demand beyond the current wave of large language model
