SK Hynix just pulled off something no foreign company has done before. The South Korean memory chip giant raised approximately $26.5 billion through its American Depositary Receipt offering on the Nasdaq Global Select Market, making it the largest first-time share sale by a foreign entity in US history.
The offering, priced at $149 per ADR, was more than seven times oversubscribed. A total of 177.9 million ADRs were sold, with each receipt representing one-tenth of a common share. Trading kicked off on July 10, 2026, under the ticker SKHY.
Why a Korean chip company needed a US address
SK Hynix has long suffered from the so-called “Korea discount,” a persistent valuation gap between South Korean firms and their global peers. The discount exists because investors have historically applied a penalty for the conglomerate structures, corporate governance quirks, and shareholder-unfriendly practices that characterize many Korean chaebol-linked companies.
The ADR listing is a direct play to close that gap. By making shares accessible to US institutional investors, SK Hynix is essentially saying: “Price us like you price our American competitors.” The company retains its primary listing on the Korea Exchange under KOSPI: 000660, so this isn’t an exit from Seoul. It’s an expansion of the investor base.
Analysts believe the ADR could serve as a catalyst for reducing the Korea discount, though a complete resolution is considered unlikely.
The AI supply chain connection
SK Hynix is a leading provider of high-bandwidth memory, or HBM, which has become the critical bottleneck component in AI data center buildouts. NVIDIA’s GPUs depend on the memory stacked alongside them, and SK Hynix supplies that memory.
Plans for the ADR were publicly detailed on June 24, 2026, with a subsequent SEC filing in early July. The speed from announcement to trading, roughly two weeks, signals how eager both the company and underwriters were to capitalize on the current market window for AI-adjacent listings.
What this means for investors and the broader market
SK Hynix just demonstrated that a well-timed US listing can generate extraordinary demand, particularly for companies positioned within the AI supply chain. However, follow-up actions from industry peers like Samsung have not been observed immediately following this sale.
The seven-times oversubscription creates a secondary market dynamic worth watching. That level of excess demand suggests many institutional allocators received smaller positions than they wanted. Those funds will likely be buying in the open market over the coming weeks, which could provide price support but also compress the discount SK Hynix was trying to eliminate faster than anyone expected.
