Samsung Electronics and SK hynix, alongside the South Korean government and major groups, announce large-scale investments to expand Korea’s semiconductor and AI infrastructure. The planned semiconductor complex in the country’s southwestern region involves 800 trillion won (reported as about $519 billion by one outlet and about $585 billion by another) from Samsung and SK hynix, with both companies building two memory chip fabs. The broader government-private plan also includes AI data centres financed by SK Group, GS Group and Naver, backed by 550 trillion won. The data-centre capacity starts at 8.4 gigawatts and is intended to reach 18.4 gigawatts by 2035.

The announcement is presented as part of the government’s three flagship megaprojects covering semiconductors, physical AI and AI data centres, aimed at meeting growing global demand driven by AI adoption. The initiatives also seek to spread high-tech investment beyond the capital region by developing industrial activity across the southwestern, central and southeastern regions. Government support includes efforts to accelerate chip-cluster construction and provide long-term funding and ecosystem development for next-generation chips, power and cooling solutions, and AI-related infrastructure. The government also promotes physical AI as a strategic industry by 2030.
