SK Hynix: HBM Memory, the New AI Goldmine, Attracts Wall Street

SK Hynix Turns to Wall Street to Fund the Future of AI

South Korean giant SK Hynix has announced its intention to raise $28 billion on the American stock market. This initiative aims not only to attract new investors but also to finance the expansion of HBM memory, a resource that has become essential in the field of artificial intelligence.

The sale of SK Hynix shares in the United States could generate approximately 43 trillion won, equivalent to $28 billion. This operation involves 17.79 million new shares that will be represented by depositary receipts traded on Nasdaq. According to Reuters, major investors have already expressed potential interest amounting to $7 billion.

The proceeds from this stock operation are intended to finance the construction of new factories in South Korea and the purchase of cutting-edge equipment. Among this equipment are extreme ultraviolet lithography systems provided by ASML, which are essential for advanced chip manufacturing.

The Growing Importance of HBM Memory in AI

In the world of artificial intelligence, processors often attract attention, but their efficiency depends on the ability to quickly process vast amounts of data. This is where memory comes into play, particularly high bandwidth memory (HBM). This technology allows multiple layers of memory to be brought closer together, significantly increasing the amount of data that processors can process simultaneously.

SK Hynix has positioned itself as a key player in this value chain, supplying HBM memory to tech giants like Nvidia and Google. In the face of growing demand, clients are seeking to secure their supplies for the coming years. To meet this demand, SK Hynix has accelerated the opening of new production capacities, reflecting tensions in the global supply.

This dynamic partly explains SK Hynix's strong stock market performance, with its shares rising by approximately 260% since the beginning of 2026. Despite the recent volatility in memory-related stocks, the company is fully benefiting from the AI boom, as HBM becomes an essential component of data centers.

The Impact of Memory Shortages on the Market

The success of HBM memory has repercussions for the entire memory market. By concentrating their efforts and investments on the most advanced products, manufacturers are creating tensions in other segments of the market. The growing demand from data centers is also driving demand for server DRAM and NAND solutions used in enterprise storage.

This pressure is already resulting in rising prices. The strong demand for AI infrastructure has stretched available capacities, contributing to the increase in memory chip prices. Furthermore, this shortage is beginning to affect other markets, such as smartphones and personal computers, complicating certain data center projects.

For companies heavily investing in AI, the cost of infrastructure has become a major issue. The price of infrastructure no longer solely depends on the number of GPUs purchased. The availability of memory, its bandwidth, and its ability to power accelerators directly influence the cost and timeline of projects.

South Korea's Strategy in Response to Global Demand

South Korea has well understood the strategic importance of these developments. Seoul has unveiled an ambitious $576 billion program dedicated to semiconductors and artificial intelligence, with SK Hynix and Samsung Electronics as industrial pillars. The country already dominates the global DRAM market, where Samsung held 38% of revenues in the first quarter of 2026, followed by SK Hynix with 29% and Micron with 22%.

However, uncertainty remains regarding the duration of this exceptional cycle. Memory manufacturers have historically experienced periods of shortage followed by overcapacity. In the short term, however, the expansion of AI infrastructure continues to place HBM memory at the center of investments.
