SK hynix priced its U.S. initial public offering on Friday, aiming to raise $26.5 billion in one of the largest stock sales ever. The South Korean chipmaker is capitalizing on a global race to build artificial intelligence datacentres that has sent its profits soaring.
The company plans to issue about 18 million shares on the Nasdaq through American depositary shares (ADS), each representing one-tenth of a regular share and priced at $149. The offering was more than seven times oversubscribed, according to U.S. media, despite recent tumbles in tech stocks over valuation fears.
The $26.5 billion raise surpasses Saudi Aramco's $25.6 billion debut in 2019 and Alibaba's $21.8 billion New York listing, though it falls far short of SpaceX's record $75 billion IPO last month. SK hynix shares rose 2.7% on Seoul's Kospi index after the announcement, adding to a gain of more than 220% this year.
The high-bandwidth memory advantage
SK hynix supplies advanced memory chips to Nvidia, the dominant player in AI processors. Together with Samsung Electronics and Micron, it controls the global market for high-bandwidth memory (HBM), a component essential for AI servers. All three companies recently saw their market capitalizations soar past $1 trillion, a milestone previously limited to about a dozen mostly American firms.
In South Korea, an image of an SK hynix jacket went viral this year as a symbol of wealth, with parody posts treating it as a "golden ticket" to luxury and status. The company's rise reflects the intense demand for HBM, which has led to shortages of other memory chips and pushed consumer electronics prices higher - Apple recently hiked the cost of its MacBooks and iPads.
Counterpoint Research analyst MS Hwang said SK hynix aims to overtake Samsung in the memory chip market. "Along with the HBM leadership it has demonstrated until recently, the company is now planning to take the lead in terms of volume as well," Hwang said. "Funds from its US listing can support such a goal."
Where the money will go
SK hynix said it will use the IPO proceeds to fund construction of the first fabrication hub at a new semiconductor cluster in Yongin, near Seoul, and to build an advanced packaging facility in the central city of Cheongju. The company is also part of a massive 800 trillion won public-private investment to build a new chip hub in southwest South Korea.
Why this matters for General, Finance, IT and Development professionals
For finance professionals, the listing underscores how AI is driving some of the largest capital raises in history, a trend that those focused on AI for Finance are tracking closely. The deal's oversubscription despite broader tech volatility signals strong investor appetite for AI hardware.
For IT and development teams, the surge in HBM demand highlights the infrastructure challenges behind AI. Building and maintaining datacentres that can handle next-generation workloads requires deep expertise in memory and processing - skills that AI for IT & Development training addresses. The chip shortage ripple effects on consumer devices also show how hardware constraints can impact product roadmaps.
