SK Hynix (SKHY) Just Priced the Biggest U.S. Listing Ever. Seoul Says $149 Is Already a Premium.
SK hynix raised $26.5 billion in the largest first-time U.S. share sale on record — and the $149 ADS price is already a ~5% premium to its own Seoul close. The parity math, the profit-quality footnote, and four scenario zones from $118 to $220.
SK hynix priced 177.9 million American Depositary Shares at $149.00 apiece on Thursday night, raising roughly $26.5 billion — eclipsing Alibaba's $25 billion in 2014 as the largest first-time U.S. share sale on record. When-issued trading under the temporary ticker SKHYV begins today; regular-way trading as SKHY starts Monday, July 13 on the Nasdaq Global Select Market.
At the offering price, the company that supplies the memory inside Nvidia's AI accelerators is worth about $1.09 trillion. And unlike almost every trillion-dollar debut before it, this one comes with a built-in answer key: SK hynix has traded in Seoul for decades. The stock already has a price. The only question the Nasdaq listing asks is what Americans will pay on top of it.
What just listed
SK hynix is not a startup with a story. It is the world's largest supplier of high-bandwidth memory — the stacked DRAM that sits millimeters from the GPU die in every serious AI accelerator — with a 56.4% global HBM market share in Q1 2026, per IDC data cited in the company's own prospectus. It is #2 in overall DRAM (29.1%) and #2 in NAND flash (18.5%).
The financials read like a typo. First-quarter 2026 revenue came in at ₩52.6 trillion (about $34 billion), up 198.1% year over year. Gross profit was ₩41.7 trillion — a 79.3% gross margin, a number more familiar from software companies than from cyclical commodity semiconductor makers. Full-year 2025 revenue of ₩97.1 trillion was itself up 46.8% from 2024. This is what the AI memory shortage looks like on an income statement: the industry sold out of supply, and pricing did the rest.
The prospectus quotes Gartner forecasting the total memory market nearly tripling from $216 billion in 2025 to $633 billion in 2026. SK hynix is the purest large-cap exposure to that number anywhere in the world — purer than Samsung (where memory is diluted by phones and appliances), purer than Micron, which closed Thursday at $991.64, up 5.7% on the day, as the whole complex repriced around the listing.

Why the stream is watching
Three things make this debut unusual, and all three matter for the price.
First, the anchor. Each ADS represents exactly one-tenth of a Seoul-listed common share. On Thursday, those shares closed at ₩2,186,000 — about $142 per ADS-equivalent at the exchange rate used in the prospectus. The $149 offering price was therefore already a ~5% premium to Seoul before a single U.S. share traded. Friday's Seoul close of ₩2,180,000 doesn't change the picture.
Second, the demand signal. Baillie Gifford, Coatue, and Situational Awareness Partners indicated interest in up to $7 billion of the offering as cornerstone investors — non-binding, but a marquee endorsement covering more than a quarter of the deal.
Third, the volatility. Seoul traded SK hynix through an 11%+ peak-to-trough swing during pricing week — ₩2,343,000 on July 6, down to ₩2,076,000 on July 8, back to ₩2,186,000 by Thursday. The anchor itself is moving.
So the setup for Monday is genuinely strange: a trillion-dollar company IPO-ing at a premium to its own visible market price, into the hottest semiconductor tape in years, with no over-allotment option for the underwriters — Korean law forbids it — and a fixed supply of ADSs at the open.
Which raises the only question that matters for anyone typing $SKHY into an order box: what is an ADS actually worth once the first-day fireworks fade — and what would make $149 look cheap, or expensive, by October?
The rest of this briefing is for paid members: the parity math that tethers SKHY to a number you can compute from Seoul's close every morning, the four scenario zones from $118 to $220, the finance-income footnote flattering the profit line, where the $26 billion actually goes, and the three dates that matter between now and October.
