South Korea's President Lee Jae Myung announced a 1,350 trillion won ($880 billion) investment plan on 29 June, framing the commitment as a national-level response to the AI infrastructure arms race now consuming every major economy.
The larger portion — 800 trillion won, approximately $518 billion — goes toward building four new semiconductor fabrication plants. Samsung and SK Hynix will each operate two, with all four located in south-west South Korea in a deliberate move to spread economic development beyond the existing chip corridors near Seoul.
Samsung Group alone plans to invest approximately 1,000 trillion won ($648 billion) domestically, covering not just chip fabrication but also AI data centres, next-generation battery technology and display manufacturing. Companies including Naver are expected to invest approximately 550 trillion won to develop 8.4 gigawatts of AI data centre capacity by 2029.
The strategic logic is clear. South Korea already dominates the high-bandwidth memory (HBM) chip market through Samsung and SK Hynix — the memory technology that has become the critical bottleneck for training and running large AI models. NVIDIA's latest GPUs depend on HBM chips manufactured almost exclusively by these two companies. The new investment plan is designed to ensure that dominance extends into the AI era.
The timing reflects the scale of global AI infrastructure competition. The United States has committed over $500 billion through various AI infrastructure initiatives. China announced a 2 trillion yuan ($295 billion) data centre programme in June. The European Union's InvestAI programme targets €200 billion. South Korea's $880 billion commitment positions the country alongside — and in some measures ahead of — these larger economies in the AI hardware race.
The investment also addresses a vulnerability. South Korea's semiconductor industry currently concentrates production in a relatively small geographic area near the North Korean border, creating geopolitical risk that global customers have increasingly flagged. Distributing new fabrication capacity across the country reduces that concentration risk while creating new economic centres.
For context engineers, South Korea's investment confirms that the AI industry's value chain begins with hardware. The companies that manufacture AI chips — particularly the HBM memory that frontier models depend on — sit at a strategic chokepoint. As AI compute demand continues to double annually, the countries and companies that control chip production will shape the pace of AI development itself.
