South Korean Giants Pledge $900B+ for Chips and AI
South Korea’s largest memory-chip makers and tech conglomerates pledged massive investments across semiconductors and AI infrastructure in a national plan announced June 29, 2026. Samsung and SK Hynix plan $518 billion to build four new memory fabs in the southwest, plus $52 billion for an HBM packaging hub. Separately, roughly $356 billion is allocated for AI data centers to be built by Korean firms including SK, GS and Naver through 2035. Samsung published a separate plan to invest 2,655 trillion won (~$1.7T) over the next decade with 425 trillion won for the Honam region; SK Group announced a 2,100 trillion won (~$1.4T) roadmap including 1,100 trillion won for chip capacity and 1,000 trillion won for AI data centers. The commitments total over $900 billion and aim to relieve global memory shortages dubbed “RAMageddon.”
Massive nationwide capital commitments (hundreds of billions to over $900B) for memory fabs and AI data centers can materially reshape global AI chip supply, relieve memory shortages, and affect pricing and capacity for AI infrastructure.

South Korea Pledges Massive Investment in Chips and AI
South Korea announced a large national investment program to secure its leadership in semiconductors and artificial intelligence. President Lee Jae Myung presented the plan together with senior figures from Samsung Electronics and SK Hynix. The government and corporates expect total investments in the coming years could exceed one quadrillion won (about €569 billion). Samsung Electronics and SK Hynix will each build two new chip factories, and the plan includes spending on data centers, robotics and new chip clusters in the southwest (notably Gwangju and South Jeolla), where local authorities plan to invest between 5 and 20 trillion won (≈€2.8–11.4 billion). The announcement aims to strengthen domestic supply chains and reduce economic concentration around Seoul, but critics question regional infrastructure and workforce readiness.
SK Hynix’s $720B AI Memory Buildout in South Korea
SK Hynix is investing $720 billion to build what it says will be the world’s largest network of memory factories, driven by rising AI demand for high-bandwidth memory (HBM). The company, now with a market capitalization above $1 trillion, raised $26.5 billion in July through a Nasdaq listing to help fund the expansion. SK Hynix controls a majority share of the HBM market and has signed long-term supply agreements with major customers, including collaboration with Nvidia. The buildout includes multiple new fabs in South Korea and a $4 billion packaging facility planned in Indiana; export controls limit sales of SK Hynix’s leading HBM products in China.
AI Chips Boost South Korea GDP to 2020 High
South Korea's economy expanded strongly in Q1 2026, with GDP rising 1.8% quarter-on-quarter — the fastest quarterly growth in about five and a half years — and 3.8% year-on-year. The rebound is attributed mainly to robust global demand for computer and high-performance memory chips used in AI data centers. Domestic firms Samsung Electronics and SK Hynix together control roughly 80% of the global supply of high‑bandwidth memory chips, with U.S. Micron supplying much of the remainder. The Korean central bank recently raised its 2026 growth forecast to 2.6%, while the IMF projects 1.9%. Despite geopolitical and energy risks, South Korea's stock market has surged (Kospi roughly doubled from ~4200 to ~8800 in 2026 YTD through early June), reflecting investor enthusiasm around the AI-driven chip boom.
