SK Hynix lists in the US: memory as the bottleneck of AI infrastructure

SK Hynix, the South Korean company, debuted on Nasdaq on July 10, 2026, through American depositary receipts (ADRs). Shares opened above the initial offer price, signaling investor support amid a global surge in demand for memory in AI servers and data centers.

The memory supercycle

In an interview with Bloomberg, Di Zhou, a portfolio manager at Thornburg Investment Management, described the current moment as a "memory supercycle": a period of unusually high and rising demand for semiconductor memory across all categories. The fundamentals are strong: order volumes for DRAM, NAND flash and high-bandwidth memory (HBM) are reaching record levels thanks to the mass construction of AI data centers.

• SK Hynix is one of the world's three largest memory makers (together with Samsung and Micron Technology)
• Debut on the US Nasdaq exchange: July 10, 2026, via American Depositary Receipts
• Specialization: DRAM (working memory), NAND flash (storage), HBM for processors and GPUs
• HBM is critical for NVIDIA H100, H200 and other AI accelerators

Memory as the bottleneck

The memory shortage has become a acute problem for AI infrastructure. GPUs can compute trillions of operations per second, but memory has to physically deliver data at the same speeds. SK Hynix's HBM (High Bandwidth Memory) is one of the few products that meets this requirement. The company has mastered advanced manufacturing technology and holds roughly 30% of the global HBM market.

The problem: major AI labs compete for memory chips as fiercely as they do for GPUs. TSMC cannot produce enough, and SK Hynix and Samsung are becoming geostrategic assets for cloud providers.

SK Hynix's position in the AI race

Over the past year, SK Hynix tripled its orders from cloud providers (AWS, Google Cloud, Microsoft Azure). The company does not compete with NVIDIA in GPUs, but without its memory no data center will reach full performance. It is a low-profile but critical and financially lucrative role. The Nasdaq IPO will let the company raise capital to expand HBM and DRAM production.

"SK

Hynix is one of the highest-quality memory companies in the world," — Di Zhou.

Investors heard that and voted with their wallets.

What this means

SK Hynix's Nasdaq debut signals a shift in investment thinking: it is not only AI model developers but also suppliers of the hardware foundation that are becoming growth leaders. The AI transformation requires physically rebuilding the planet: data centers, power systems and, critically, memory. For the foreseeable years, memory will remain a scarce resource, and companies like SK Hynix will set the pace of AI innovation.
