SK Hynix and Samsung gained from surging demand for high-bandwidth memory tied to OpenAI’s $500bn AI buildout.
Shares of SK Hynix jumped nearly 10% and Samsung Electronics rose over 3% after the announcement in Seoul trading.
OpenAI chose both firms to supply advanced memory chips for its massive “Stargate” data-centre initiative.
Samsung Electronics leads global memory production, dominating DRAM and NAND flash markets that power servers and devices.
SK Hynix ranks second in DRAM output but leads in high-bandwidth memory, vital for Nvidia’s artificial intelligence processors.
Together, the two companies control over half of global memory supply, influencing prices, capacity, and technology shifts.
Demand Locks in Advanced Memory Growth
High-bandwidth memory enables AI chips to process enormous data volumes at lightning speed, unlike standard memory systems.
The Stargate project will build a global network of AI supercomputers spanning multiple continents, industry analysts confirmed.
Experts estimate the project will consume hundreds of thousands of HBM wafers or stacks each month.
Such volumes would reshape semiconductor capacity worldwide, solidifying SK Hynix’s lead in HBM3 production.
Samsung aims to leverage the opportunity to expand its presence in next-generation HBM4 development.
The initiative ensures both Korean firms anchor the AI supply chain during a surge in investment and demand.
South Korea Strengthens Role in AI Strategy
The Stargate project carries profound strategic importance for South Korea’s ambitions beyond hardware manufacturing.
Hosting one of the world’s largest AI infrastructures reinforces Seoul’s position as a regional technology powerhouse.
OpenAI’s investment aligns with Washington’s push to base key facilities in allied, politically stable countries.
By supporting OpenAI, South Korea strengthens global technology ties while reducing reliance on China-sensitive AI supply lines.
Korea’s export-driven memory sector offers unmatched production scale combined with strong political alignment with the United States.
The collaboration positions South Korea as a central hub in the future of artificial intelligence infrastructure.
