SK Hynix targets $14 billion US listing as AI memory demand surges

SK Hynix plans to list in the US as soon as August, betting a 240% stock rally can sustain investor appetite for the AI memory boom.

South Korea's SK Hynix expects SEC approval for its US ADR listing during the week of June 22, with a debut as soon as August, as the memory chipmaker races to triple wafer capacity by 2034 to meet AI demand.

"SK Hynix plans to issue ADRs within 2026, but the details, including the size and timing, have not yet been decided," the company said in a statement. Chairman Chey Tae-won said wafer capacity will double within five years and triple by around 2034, with the first phase of four new fabrication plants in South Korea scheduled for completion early next year.

The offering could raise as much as $14 billion, according to a person familiar with the matter who asked not to be identified because the information is private. SK Hynix confidentially filed for the listing in March. Its shares have surged 240% this year, pushing its market value past $1 trillion in May — making it only the third Asian company after Taiwan Semiconductor Manufacturing Co. and Samsung Electronics to reach that milestone.

The listing would plug SK Hynix directly into the US appetite for AI stocks at a moment when the pipeline is crowded with marquee names. OpenAI and Anthropic have both filed for IPOs, and SpaceX's blockbuster offering is approaching. For SK Hynix, the move broadens its investor base beyond Seoul and provides fresh capital for the capacity expansion the AI boom demands — construction of its four South Korean fabs will continue through 2034, a decade ahead of the original schedule.

Capacity Expansion Targets a Structural Shortage

SK Hynix is the dominant supplier of high-bandwidth memory (HBM), the stacked DRAM that Nvidia's AI accelerators depend on. The company recently signed a multi-year deal with Nvidia to co-develop memory for its next-generation chips, locking in demand as Jensen Huang warned the memory shortage could last for years.

The capacity buildout is aggressive. After completing domestic plants, SK Hynix will consider building factories overseas, including in Japan, where Chey said all necessary infrastructure already exists. The expansion comes as memory makers have deliberately restrained new capacity additions to maintain pricing discipline — a strategy that has boosted margins but created the exact supply gap that AI demand is now exploiting.

A Crowded US IPO Pipeline Tests Investor Appetite

An August debut would add SK Hynix to what is shaping up to be a busy second half for US equity markets. Investors are closely watching a wave of AI-related listings, including OpenAI, Anthropic, and SpaceX, whose IPO demand is approaching four times oversubscribed, according to a person familiar with the matter.

For SK Hynix, the timing aligns with peak market enthusiasm for AI-linked semiconductor stocks. The company's 240% year-to-date gain reflects its dominant position in HBM, where it holds the majority of early HBM4 supply. But the question for investors is whether the memory cycle stays hot long enough to reward buyers after such a run.

SK Hynix trades at a premium to historical multiples as the market prices sustained AI-driven scarcity. The US listing could unlock additional demand from institutional investors who cannot easily access Korean-listed shares. However, Elon Musk's proposed $122 billion Terafab — a vertically integrated chip manufacturing complex — looms as a long-term risk to memory pricing power, though meaningful supply impact is unlikely before 2030.
