SK Hynix's Record $26.5B ADR Sinks Below Its Offering Price

SK Hynix's record-breaking $26.5 billion Nasdaq ADR listing — the largest US debut ever by a foreign company — has round-tripped straight back to its $149 offering price, and in some sessions slipped below it, even as Nvidia-linked headlines have been flashing bullish signals for AI chip demand. The reversal is a sharp reminder that a hot IPO and a hot sector don't guarantee a stock stays up.

What happened

SK Hynix ADRs (ticker: SKHY) began trading on Nasdaq on July 9 at a reference price of $149 per share, priced at the top of demand after the offering was oversubscribed more than seven times. Shares opened around $170 and closed the first session near $168, a roughly 13-14% pop that made headlines as the biggest US listing by a foreign company in history, edging out Alibaba's 2014 record.

The euphoria didn't last. By July 13, the ADR had plunged as much as 9.3% in a single session to close at $152.35, erasing most of the debut rally. Days later, the stock broke below its own $149 listing price entirely, wiping out the entire "pop" investors paid a premium to chase. As of July 26, SKHY was still bouncing in a wide range between roughly $153 and $164 — trading essentially flat to its IPO price nearly three weeks after a listing that was supposed to be a slam-dunk win.

Why it matters

The timing is what makes this notable. Nvidia — the company whose AI chips SK Hynix's high-bandwidth memory (HBM) directly feeds — has had a run of arguably positive news, including talk of a multibillion-dollar backstop arrangement with OpenAI and a new AI infrastructure partnership involving SK Group itself. Yet none of that has been enough to lift SK Hynix's ADR back to its debut highs. That's a decoupling worth noting: HBM is supposed to be one of the most direct beneficiaries of Nvidia's AI buildout, but investors are pricing SK Hynix's US shares as if the "Nvidia halo" isn't automatically transferring.

Instead, the ADR's slide has tracked broader skepticism about whether AI-driven memory earnings can justify the multiples buyers paid at the IPO, plus straightforward profit-taking from investors who bought the opening pop. As I covered in Kospi's 5.7% 'Black Friday' Crash Slams SK Hynix's New Nasdaq ADR, the ADR's steepest drop came directly on the heels of SK Hynix's Korean-listed shares (000660) falling more than 15% in Seoul on the same trading day — a reminder that the ADR doesn't trade in a vacuum from its home-market stock.

Who's affected

SK Hynix itself is the obvious one: the company raised the capital specifically to fund Korean fab expansion and EUV lithography equipment purchases, so a depressed ADR makes any future follow-on capital raise more expensive. The broader Korean memory complex is also in the crosshairs — Samsung, SK Hynix's chief domestic rival, has had its own volatile stretch, as detailed in Samsung Plunges 7.6% as Kospi's 5.72% Crash Triggers $5B Sell-Off, even as S&P separately named Samsung memory's "top winner" on outlook upgrades. That split — one ratings agency bullish on the sector's fundamentals while ADR investors sell the actual stock — captures just how contested the AI-memory valuation debate has become right now.

It also feeds into the wider credit-market unease around AI capital spending that I flagged in Moody's Warns AI Spending Threatens Big Tech's Credit: when even a company sitting at the center of AI hardware demand can't hold its IPO pop, it adds to the case that markets are starting to demand proof, not just a growth story, from AI infrastructure plays.

What to watch next

SK Hynix reports second-quarter earnings on July 29, and that print will be the next real test of whether the ADR can reclaim ground above $149. Investors will be watching HBM order visibility and any commentary on 2027 capacity commitments tied to the capital the ADR offering was meant to fund. Beyond that, keep an eye on hyperscaler capex guidance from Microsoft, Meta, Amazon and Google as they report earnings this same window — soft signals there would compound pressure on SK Hynix's US shares regardless of what Nvidia's own stock does day to day. Also worth tracking is the ADR-to-common-share conversion mechanics and premium, since a persistently thin or negative premium versus the Seoul-listed stock is itself a signal of how much confidence US investors still have in the listing.

This is not financial advice — always do your own research before making investment decisions.

The bigger takeaway is that a record-setting IPO number and a hyped sector narrative aren't the same thing as sustained investor conviction. SK Hynix's ADR proved it could attract enormous demand on day one; the past three weeks have shown that holding onto that demand — even with Nvidia-adjacent tailwinds in the headlines — is a separate and much harder problem.
