SKHX Climbs Into SK Hynix's Nasdaq Debut as $28B Book Runs 7x Oversubscribed

The Catalyst

SK Hynix closed the institutional order book on its US listing early on July 8, with the offering reported to be more than seven times oversubscribed. The company is selling 177.9 million American depositary receipts — each representing one-tenth of a Seoul-listed common share — to raise roughly $28 billion, a figure that would make this the second-largest share sale in history, behind only SpaceX's ~$85.7 billion raise last month. Final pricing lands Thursday, July 9, with the ADRs set to begin trading on Nasdaq under SKHY on Friday, July 10. Demand skewed toward long-only funds, tech-sector specialists and sovereign wealth vehicles — the sticky capital you want anchoring the largest foreign listing the US market has ever seen.

Why the Perp Still Trades Below the Deal

SKHX tracks one full SK Hynix common share, converting the Seoul price (KRX: 000660) from won to dollars at the live USD/KRW rate. At ~$1,416 the perp implies roughly $142 per ADR-equivalent, versus the ~$158 reference price set off the stock's July 3 close — and Reuters flagged the ADSs could ultimately price nearer $166. Either way the perp is sitting somewhere around 10% under the deal even after this bounce. The gap exists precisely because US investors still can't buy the stock: the discount is the market's real-time handicap on where a heavily oversubscribed book actually clears. The $875 million in 24-hour perp volume shows traders using SKHX to position around the pricing rather than wait for the tape to open.

The AI Memory Trade Underneath

This isn't a bet on some random Korean chipmaker. SK Hynix controls roughly 60% of the high-bandwidth memory market — the stacked DRAM that sits beside Nvidia's H100, H200 and Blackwell accelerators — and it crossed a $1 trillion valuation in late May. First-quarter revenue landed near ₩52.6 trillion with operating margins reported above 70%, numbers that only make sense in the middle of an acute AI memory shortage. The listing is a capacity play: SK Hynix wants US capital to fund more fabs while HBM demand keeps outrunning supply. That's the durable reason global funds piled into the book at 7x.

What to Watch

Two prints matter. Thursday's final ADR price tells you where the largest institutions actually anchored — land it near the top of the range and SKHX's ~10% discount reads like a setup rather than a warning. Friday's Nasdaq open then gives the perp its first live US reference to arbitrage against, and the gap to the deal should compress or blow out fast depending on how the debut trades. The wildcard is the underlying: 000660 sold off hard from its June 25 record of ₩2,987,000 into this listing amid a broader memory-stock pullback, and any Seoul weakness feeds straight through the oracle into SKHX regardless of how the ADR itself opens.
