South Korea announces $1T+ AI, chip mega-investment led by Samsung, SK Hynix through 2035

South Korea unveiled a sweeping semiconductor and AI industrial strategy on June 29, anchored by $518 billion in chip fabrication investment from Samsung Electronics and SK Hynix to build two new fabs each in the country's southwest. The government also earmarked 81 trillion won ($52.5 billion) for a chip-packaging cluster near Seoul and backed 550 trillion won ($356 billion) in AI data-center investments from SK Group, GS Group, and Naver by 2029. By 2035, the nation targets total AI data-center investment exceeding 1,000 trillion won ($648 billion), supporting 18.4 gigawatts of compute infrastructure.

President Lee Jae Myung framed the initiative as a 'great leap forward' on the 'triple axis' of semiconductors, physical AI, and data centers, positioning South Korea to 'secure the core elements of AI faster than any other country.' The strategy reflects Samsung and SK Hynix's commanding position in high-bandwidth memory (HBM) chips, now essential to global AI accelerator systems. Stock prices for both chipmakers dipped post-announcement (Samsung -4.86%, SK Hynix -1.68%), with some analysts cautioning that the surge could fuel oversupply.

For architects planning AI infrastructure capex and memory supply chains, South Korea's bet signals sustained HBM capacity scarcity through the decade and geopolitical fragmentation of chip manufacturing. SK Hynix's pending Nasdaq listing ($29 billion) and Samsung's southern expansion tighten Korean firms' position as indispensable to NVIDIA-equivalent GPU ecosystems, potentially constraining TSMC's foundry leverage and reshaping equipment-supply dependencies for 2nm node scale-up.
