SKHX Reclaims the ADR Pricing Line as SK Hynix's Seoul Shares Jump 5%

Back to the Pricing Line

SKHX trades at $1,490, up 4.84% over the last 23 hours, and that number is not a coincidence. Ten ADRs make one SK Hynix common share, and the company priced its US offering at $149 per ADR, which pins the perp's fair value at exactly $1,490. After SKHX faded below that line when the deal priced, it has now reconverged onto it — pulled up by the underlying, not by anything specific to the perp.

SKHX is oracle-priced off the KRW spot of Seoul-listed 000660, converted to USD, and those shares rose 5.30% Thursday to ₩2,186,000. The perp's 4.84% is that Seoul session filtered through the USD/KRW rate. This isn't a Hyperliquid narrative — it's the Korean close doing the work, and the perp mechanically following it back to par with the offering price.

The Deal That Moved It

The catalyst upstream is the offering. SK Hynix priced roughly $26.5 billion of ADRs, a raise set to top Alibaba's $25 billion 2014 debut and stand as the largest first-time US listing by a foreign issuer. The book came more than seven times oversubscribed, and the demand isn't hard to explain.

SK Hynix is the primary HBM supplier into Nvidia's AI accelerators and the dominant name in high-bandwidth memory, and it posted record Q1 profit on climbing memory prices. Raising dollars now — stock richly valued, the HBM order book effectively sold out for 2026 — funds new fabs without adding debt. UBS went further and flagged an arbitrage between the ADR and the Seoul line.

Does the Premium Cross the Pacific?

Here's the live question for anyone holding SKHX. The ADR opens for when-issued trading Friday on Nasdaq under SKHY, and Korean desks are split on whether a US premium re-rates the underlying or stays stranded on the American side. Shinhan Securities points to conversion constraints — the regulatory approval needed to swap common shares into ADRs — which, as with TSMC's persistent ~19% ADR premium, could let a US-only premium hold. KB Securities takes the other side, arguing the ADR and the Seoul shares re-rate simultaneously.

For SKHX the distinction is everything: the perp tracks KRW spot, so it captures the underlying's move but not any premium that lives only in the ADR. If the KB view wins and Seoul catches a sympathetic bid off a strong debut, SKHX has room above $1,490. If the premium stays trapped on the US side, the perp stays tethered to the Korean close — right where it sits now.
