$29 billion — the memory AI wants just pushed this company onto US markets
Korean memory chip giant SK Hynix's US IPO is in final countdown — issuance starts July 10, subscription and payment July 14, official Nasdaq listing July 29, ticker SKHY. The raise is about $29 billion, the largest foreign-company ADR offering in US market history.
A memory chip maker raising this much — why? Two words: AI.
HBM, the hard currency of the AI era
SK Hynix's lifeline right now is HBM (high-bandwidth memory). It's a critical component in AI training and inference chips — Nvidia's GPUs need HBM as VRAM to run large models, or all that compute starves for data.
SK Hynix holds the largest share of the global HBM market, ahead of Samsung and Micron. In 2025 AI compute demand exploded, HBM went short, prices soared. Fortune reported the numbers: for 2026 SK Hynix is projected to post 221 trillion won (about $144 billion) in net income, up 415% year on year; revenue of 355 trillion won (about $231 billion), up 265%.
Net income up over fourfold in a year — this isn't a normal business, it's a company riding a once-in-a-generation tailwind.
Why list in the US, not Korea
Fair question. The answer is blunt — US markets offer higher valuations, deeper capital pools, and a denser base of AI-theme investors. SK Hynix needs to expand HBM capacity, and a single new fab runs into the billions. Korea's market alone can't fuel that.
More importantly, AI supply-chain capital clusters in US equities. Nvidia, Broadcom, AMD all list there, and investors there have the highest appetite for the "AI memory" story. Listing on Nasdaq puts SK Hynix directly in front of that money.
What it signals for the industry
This IPO isn't just about SK Hynix. It sends a few signals:
- AI hardware is still accelerating: a memory giant willing to raise $29B to expand means the industry bets AI compute demand keeps burning for years
- HBM is the new battleground: Samsung and Micron are both chasing share — the capacity race among the three is just starting
- Semiconductor equipment benefits: expansion means buying gear, orders flow to ASML, Applied Materials and the like
There's risk too. If AI compute demand growth slows in 2027 and HBM prices turn, the new capacity becomes a burden. But for now, the market is betting "still going up."
In one line: AI pushed a memory company onto the largest foreign-company IPO seat in US history. The next question is how long this wind keeps blowing.
