South Korean chip giant SK Hynix successfully raised $26.5 billion in its U.S. share offering, marking it as the largest listing by a foreign company in the U.S. and the second-biggest IPO in U.S. market history, trailing only SpaceX's $85.7 billion offering. The company sold 177.9 million American depositary shares (ADRs) at $149 each, with trading commencing on the Nasdaq under the ticker symbol "SKHYV" and expected to switch to "SKHY" for regular trading on Monday. Each ADR represents one-tenth of a Seoul-traded common share.
The offering saw immense demand, with orders during the book-building process reportedly over seven times the number of shares available, highlighting significant investor appetite for companies crucial to the artificial intelligence (AI) supply chain. Nearly half of the ADRs were allocated to the top 10 orders, with interest approaching $200 billion. This strong demand allowed the ADRs to be priced at about a 2.9% premium compared to SK Hynix's closing price of 2.19 million won ($1,450) on the Korean stock market.
SK Hynix intends to use the proceeds solely for facilities and equipment, including the construction of a new fab at the Yongin semiconductor cluster, a P&T7 advanced packaging and test plant in Cheongju, and the acquisition of extreme ultraviolet (EUV) lithography scanners from ASML. These investments are strategic, aimed at expanding its capacity for advanced DRAM and high-bandwidth memory (HBM), and addressing packaging bottlenecks to maintain its dominant position in the HBM market, where it held 58% by revenue in Q1 2026. The listing also provides U.S. investors direct access to SK Hynix shares, bypassing the complexities of overseas trading.
Analysts view this listing as a pivotal moment for the memory chip sector and a "yardstick to test the water" for continued investor enthusiasm. Experts like Seoul National University finance professor Jaewon Choi noted that the U.S. listing offers easier access to substantial investment capital. Dave Mazza, CEO of Roundhill Investments, emphasized that the listing removes an accessibility barrier for many U.S. institutions. There is also an expectation that the ADRs could trade at a premium, potentially leading to a re-rating of both the ADRs and Seoul shares as global access improves, similar to the case of TSMC's ADR listing in 1997. Economist Baek Seok-hyun of Shinhan Bank also noted that the planned conversion of a portion of the dollar proceeds into won could support the Korean currency.
Bank of America, Citigroup, Goldman Sachs, and JPMorgan acted as joint bookrunners for the offering. The successful listing surpasses Alibaba's $25 billion New York listing in 2014 as the largest U.S. IPO by a foreign company. The offering's scale and the positive market reaction signal strong confidence in SK Hynix's role as a key supplier for AI chip giant Nvidia and its future growth prospects in the rapidly expanding AI market.
