A South Korean chipmaker that supplies Nvidia prices roughly $28 billion of U.S. shares Thursday. The result will be a verdict on whether AI's spending cycle still pays for itself.
SK hynix hits the Nasdaq capital tap Thursday, looking to raise roughly $28 billion in U.S.-listed shares of a South Korean chipmaker whose memory sits inside most of the world's AI servers. If the deal trades higher on Friday, public capital is voting that AI infrastructure has staying power. If the debut wobbles, a seven-times-oversubscribed book will not insulate the company from the broader worry that AI capacity is being built faster than AI revenue.
The company plans to issue the equivalent of about 18 million new shares on Nasdaq on Friday through American Depositary Receipts, the financial instruments that let foreign shares trade on U.S. exchanges. The Korean disclosures and the Form F-1 filed with the SEC target a raise of 43 trillion won, roughly $28 billion, revised down from an initial target above 45 trillion won. Bloomberg reported the deal was more than seven times oversubscribed.
SK hynix is the dominant supplier to Nvidia of high-bandwidth memory, or HBM, the specialized chips that sit alongside Nvidia's AI processors. Its shares are up more than 200% year-to-date. The company sits in a three-firm oligopoly for HBM, alongside Samsung Electronics and Micron, both of which have also crossed $1 trillion in market capitalization on AI demand. Those three control the global HBM market.
Global tech stocks have sold off in recent weeks on fears of stretched AI valuations and on questions about when the trillions of dollars in planned AI capacity spending will produce returns. SK hynix sits at the intersection of that spend. Every high-end AI server needs HBM, and HBM supply is set by three firms, including SK hynix.
The $28 billion target would not match SpaceX's roughly $75 billion U.S. offering last month, but it would rival Saudi Aramco's $25.6 billion 2019 debut and the $21.8 billion Alibaba raised when it listed in New York. The Fool analyzed the F-1 filing for the comparisons.
As chipmakers reroute capacity toward the more lucrative HBM used in AI servers, the market for the less exotic memory inside laptops and tablets has tightened. Apple raised prices on MacBooks and iPads earlier this year, in part because of memory-component costs, and Counterpoint Research analysts expect those increases to persist into 2027 as new HBM capacity comes online slowly.
Earlier coverage of the listing plans framed the deal as a way for SK hynix to broaden its investor base beyond Seoul's Kospi exchange. That case is stronger now than it was then, because the company needs sustained capital to fund capacity expansions that AI customers are ordering in volume. Pepperstone research strategist Dilin Wu called the offering "a huge development that should broaden the capital base for the memory sector," per Yahoo Finance.
For the broader market, Friday's trade is a clean test. A healthy debut would suggest capital allocators still treat AI infrastructure as a durable, multi-year buildout capable of absorbing new equity through cycles. A flat or down open would echo the recent selloff in AI-exposed U.S. tech names and force a recalculation of how much of the spending cycle is already in the price.
The listing will not, on its own, settle whether AI is overbuilt. It will tell investors how much of that worry is already there.
