South Korea Announces $576 Billion AI and Chip Investment Plan Led by Samsung and SK Hynix

South Korea announced three flagship megaprojects on June 29, 2026, totaling over $576 billion in investments to cement its global leadership in semiconductors and artificial intelligence. Samsung Electronics and SK Hynix will invest 800 trillion won ($519 billion) to build semiconductor complexes in the southwestern region, with each company constructing two memory chip fabs and the government helping double memory chip production capacity within five years. SK Group, GS Group, and Naver will invest 550 trillion won to establish AI data centers with 8.4 gigawatts of initial capacity, expanding to 18.4 gigawatts by 2035. President Lee Jae Myung stated the megaprojects' results will determine Korea's fate for the next 20 to 30 years, with the government investing over 30 trillion won in next-generation chips and aiming to make South Korea one of the world's top three AI robot powers by 2030.
