OpenAI tapped SK Hynix and Samsung to supply high-bandwidth memory for its $500bn Stargate AI project.
SK Hynix shares jumped nearly 10%, and Samsung Electronics rose over 3% after the announcement.
Samsung dominates global DRAM and NAND production, while SK Hynix leads in HBM, critical for AI processing.
Together, they control more than half of the global memory market, influencing prices, capacity, and innovation.
Industry analysts predict the Stargate project will trigger unprecedented investment across the AI supply chain.
The collaboration reinforces South Korea’s role as a central player in global semiconductor production.
HBM Drives Next-Generation AI Performance
High-bandwidth memory allows AI chips to move massive data volumes at extreme speeds, beyond standard memory limits.
Stargate will deploy supercomputers across continents, requiring hundreds of thousands of HBM stacks each month.
SK Hynix will supply HBM3 chips, while Samsung expands into next-generation HBM4 production to meet demand.
The project could reshape global semiconductor capacity, boosting both companies’ influence in AI infrastructure.
Analysts say the initiative strengthens Korea’s position in the rapidly evolving AI ecosystem.
HBM’s ultra-fast performance enables large-scale model training and deployment that conventional memory cannot support.
Seoul Gains Strategic AI Advantage
Hosting the Stargate project positions South Korea as a regional technology hub beyond hardware manufacturing.
OpenAI and its U.S. backers deepen ties with Seoul while reducing reliance on China-sensitive AI supply chains.
Korea’s export-driven memory industry provides the scale and political alignment Washington seeks for critical facilities.
Experts note the project strengthens U.S.–Korea cooperation and underscores the country’s importance in AI development.
Seoul benefits from both economic growth and enhanced global influence in next-generation technologies.
The Stargate project could cement South Korea as a central node in international AI infrastructure networks.
