Shares surged as SK hynix, the South Korean chipmaker that supplies the memory inside nearly every major AI processor, opened trading on the Nasdaq at $170 — closing its first day up roughly 13% at $168.01 . The company raised $26.5 billion, marking the biggest first-time listing by a foreign company in the U.S. — eclipsing Alibaba's 2014 record. For existing Seoul-listed shareholders, the question now is whether a U.S. listing can sustain a valuation that has already grown sevenfold in a year.
Seven Buyers for Every Share Signals Conviction — and Risk
Demand was running at seven times the available shares . About $5 billion in shares went to three cornerstone investors — Baillie Gifford, Coatue Management, and Situational Awareness Partners . That level of institutional backing suggests big money sees SK hynix as a durable AI play, not a trade. But heavy oversubscription also means the stock priced at a discount to demand, inflating the day-one pop — a gain that enriches new buyers, not the company's balance sheet.
The "Korea Discount" May Finally Have an Expiration Date
The listing tests whether SK hynix can shed its long-standing "Korea discount" — the tendency of South Korean companies to trade at lower valuations than global peers due to governance concerns . U.S. rival Micron, despite having less market share in key memory products, has benefited from direct access to the world's largest pool of investors . A Nasdaq ticker could narrow that gap over time by pulling SK hynix into index funds and U.S. institutional portfolios.
$26.5 Billion Buys Factories, but the Capacity Race Is Far From Won
SK hynix is building a $4 billion plant in Indiana for advanced packaging — the process of stacking individual chips into larger AI-ready systems — scheduled for completion in 2028 . Analysts expect SK hynix's share of the high-bandwidth memory market to slip from roughly 57% to the low-40% range as Samsung gains ground and Micron solidifies its position . Even announced factory expansions remain "insufficient to meet expected demand through the end of the decade."
Memory Is Cyclical — AI or Not
Annual revenue almost tripled from 2023 to 2025, reaching about $65 billion , and net income hit 40.34 trillion won (~$26.6 billion) in Q1 2026 alone . Those are staggering numbers. But as one analyst warned: "This is how memory always acts in any megacycle... The problem is, it always crashes hard."
The current chip shortage could last into 2030 , but investors paying a trillion-dollar price tag are betting the cycle this time bends, not breaks.
