SK Hynix IPO in the US: memory as a bottleneck in AI infrastructure

SK Hynix, a South Korean company, made its debut on Nasdaq on July 10, 2026, through American Depositary Receipts (ADRs). Quotations opened above the initial offering price, signaling investor support against the backdrop of a global surge in demand for memory for AI servers and data centers.

Memory Supercycle

Thornburg Investment Management portfolio manager Di Zhou called the current moment a "supercycle of memory" in a Bloomberg interview — a period of abnormally high and growing demand for semiconductor memory across all categories. Fundamentals are strong: order volumes for DRAM, NAND flash, and high-bandwidth memory (HBM) are reaching record levels thanks to massive AI data center construction.

• SK Hynix is one of the three largest memory manufacturers globally (along with Samsung and Micron Technology)
• Debut on the American Nasdaq exchange: July 10, 2026, via American Depositary Receipts
• Specialization: DRAM (random access memory), NAND flash (storage), HBM for processors and GPUs
• HBM is critical for NVIDIA H100, H200, and other AI accelerators

Memory as a Bottleneck

Memory shortage has become an acute problem for AI infrastructure. Computing units (GPUs) can calculate trillions of operations per second, but memory must physically deliver data at the same speeds. HBM (High Bandwidth Memory) from SK Hynix is one of the few products meeting this requirement. The company has mastered cutting-edge manufacturing technologies and holds approximately 30% of the global HBM market.

The problem: major AI labs compete for memory chips as actively as they do for GPUs. TSMC cannot produce enough — 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 has tripled orders from cloud providers (AWS, Google Cloud, Microsoft Azure). The company does not compete with NVIDIA on GPUs, but without its memory, no data center will achieve full performance. It's a low-profile, yet critical and financially rewarding role. The Nasdaq IPO will allow the company to 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 this and voted with their price.

What This Means

SK Hynix's debut on Nasdaq symbolizes a shift in investment paradigm: not only AI model developers, but also suppliers of hardware foundations are becoming growth leaders. AI transformation requires physical re-equipment of the planet — construction of data centers, power systems, and critically — memory. In the foreseeable years, memory will remain a scarce resource, and companies like SK Hynix will determine the pace of AI innovation.
