South Korea's SK Hynix said it plans to raise as much as $29.4 billion through a U.S. stock listing, underscoring how aggressively the semiconductor industry is moving to capitalize on the insatiable demand for advanced memory used in artificial-intelligence systems.
The company, the world's second-largest memory chip maker, confirmed on June 24 that it intends to list American Depositary Receipts on Nasdaq, with trading expected to begin in July. The sum would make it one of the largest IPOs in history, exceeding even the $25 billion raised by SoftBank's Arm Holdings in 2023. At $29.4 billion, the offering would also dwarf the largest U.S. tech debuts of the past decade.
SK Hynix's ambition reflects the central role that high-bandwidth memory, or HBM, has assumed in the AI boom. The specialized chips are stacked directly onto AI accelerators from Nvidia and others, dramatically increasing the speed at which models can process data. As leading AI labs have raced to expand their training and inference capacity, demand for HBM has far outstripped supply, sending profit margins for specialized memory producers to extraordinary heights.
Analysts expect the proceeds to fund a significant expansion of SK Hynix's advanced packaging capacity and its next-generation HBM production lines. The company currently supplies roughly 70% of the world's HBM, giving it leverage in negotiations with customers and pricing power that has surprised even bullish observers. But rivals, including Samsung and Micron, are closing the gap, and the industry is preparing for a wave of new supply to hit the market over the next 18 months.
The listing would also add a major new player to the U.S. public equity markets at a time when the New York Stock Exchange and Nasdaq are competing fiercely for high-profile overseas listings. South Korean officials have welcomed the move as a sign of deepening economic ties with the United States, while investors have scrutinized the offering as a barometer for how long the AI infrastructure spending boom will last.
Still, some analysts caution that memory chips are inherently cyclical. The semiconductor industry has a long history of overbuilding during booms, only to face sharp price collapses when new capacity floods the market. Whether SK Hynix's $29.4 billion bet pays off may depend less on this year's demand than on whether AI workloads continue to grow at their current pace through the end of the decade.
