SKHX Grinds Higher as SK hynix's $28B Nasdaq Book Runs Multiple Times Oversubscribed

The Book Into Pricing

The catalyst under SKHX is no longer speculation about demand — it's confirmed demand. Bloomberg reported on July 7 that SK hynix's U.S. listing is multiple times oversubscribed ahead of pricing, and the perp has drifted up 6.88% over 22 hours to roughly $1,493 as that book fills.

The structure: SK hynix is launching a ~$28.21 billion ADR offering on the Nasdaq under the ticker SKHY, with pricing set for July 9 and trading expected to begin July 10. That would rank as the largest ADR listing in Wall Street history, surpassing Alibaba's 2014 debut. The deal was trimmed from an initial ~$29.65 billion target after the stock dropped nearly 12% in a single June session on reports Nvidia might cut Rubin production — so the fact that it's now oversubscribed at the reduced size is the real signal. Cornerstone names including Coatue, Baillie Gifford and Leopold Aschenbrenner's Situational Awareness Partners have jointly indicated up to $7 billion.

Decoupling From the Memory Selloff

The most interesting thing about this bid is what it's *not* trading with. SK hynix is holding up while the broader memory complex sells off — Samsung and Micron have been under pressure into the same window. That's not sector beta; it's a flight to the single asset with the cleanest AI-memory story.

The fundamentals back the discrimination. SK hynix controls roughly 57% of the high-bandwidth memory market that every Nvidia accelerator depends on, and its 2026 HBM output is effectively sold out. Q1 was a record — revenue up 198% year over year with an operating margin above 72% — and the stock has cleared a $1 trillion market cap. When traders are picking one memory name to own through a selloff, this is the one they pick.

What Pricing Sets Up

Thursday's print is the next hard catalyst. The ADSs have been guided near $166 against a ~$158 reference, and a strong price sets the reference the Friday debut trades off of. Because SKHX tracks the KRW-listed common share converted to USD, listing-related flows and sentiment tend to bleed straight into the perp — the oracle price and the ADR narrative are moving the same underlying.

The counterweight: the offering issues new shares, so there's real dilution, and debuts this size carry bookbuild and first-day volatility. A soft print, or the memory selloff finally catching up to Hynix, is what invalidates the grind. For now the tape is doing the simple thing — pricing in a book that's already oversubscribed.
