What happened
SK Hynix is investing $720 billion to build the world's largest network of memory factories at its Yongin Cluster, with production starting in February. The company now controls 58% of the high-bandwidth memory (HBM) market and its market cap has topped $1 trillion after a fivefold jump in the past year. South Korea's president is pushing both SK Hynix and Samsung to expand capacity under a national plan backed by at least $22 billion in chip support.
Why it matters
HBM supply constraints directly drive GPU scarcity and cloud compute pricing for anyone training or deploying AI models. If SK Hynix's Yongin fab comes online as planned in February, HBM supply could loosen, potentially easing GPU availability and cost for AI builders. Founders budgeting for AI infrastructure should track this timeline rather than assuming current compute costs are permanent.
Discussion angle
How should AI-dependent startups plan infrastructure budgets around the possibility that HBM supply loosens in 2027 versus the risk that demand outpaces even this $720B buildout?
