SK Hynix Files for U.S. IPO as AI Memory Demand Outruns Supply

SK Hynix, the South Korean memory chip supplier to Nvidia, filed confidentially for a U.S. initial public offering, a person familiar with the matter said. The company did not disclose the size or timing of the deal. Bankers expect it to rank among the largest technology IPOs of the past decade, the person said.

The filing lands as the memory chip cycle turns. DRAM prices stabilized after a 2023 correction. Demand for high-bandwidth memory – the HBM3E chips SK Hynix supplies to Nvidia – is outstripping supply. The company controls roughly half the global HBM market, a position that pushed its operating profit to record levels in recent quarters.

The IPO gives U.S. investors direct exposure to that HBM franchise. SK Hynix already trades in Seoul at about 12 times forward earnings. U.S. memory peer Micron trades closer to 20 times. The discount reflects a Korea-specific risk premium that a U.S. listing could narrow, several sell-side analysts said.

The capital raise comes with an unusual use-of-proceeds angle for a semiconductor IPO. SK Hynix is spending roughly $15 billion on a new memory fab in Indiana, its first U.S. production site. The plant is scheduled to begin output in 2028. IPO proceeds will fund that buildout, the person familiar said, reducing the company's reliance on debt and Korean government subsidies.

For traders sizing the deal, the comparison to Arm Holdings' September 2023 IPO is instructive. Arm – another dominant chip supplier, also controlled by a large Asian parent – priced a $5.2 billion ADS offering that quickly doubled. SK Hynix is larger, with higher revenue and a more visible growth driver in AI memory. It also carries political risk. The Biden administration's $8.5 billion grant to the Indiana fab was part of the CHIPS Act. Any congressional recalibration of that program could hit the project's economics.

The IPO pipeline matters for sponsor-backed exits. A successful SK Hynix listing would open a window for other semiconductor and AI-adjacent companies considering U.S. floats, bankers said. The deal's pricing, expected in the second or third quarter, will test whether the market's appetite for AI hardware extends past chip design into memory manufacturing.

Five other IPOs are scheduled to list in the week ahead, including four set to raise more than $100 million.
