SK海力士290亿美元纳斯达克上市，瞄准AI内存需求

SK Hynix is taking a $29B Nasdaq listing to US investors hungry for AI memory exposure.

The company already leads in high-bandwidth memory, the chip stack feeding Nvidia-style AI systems.

US investors could buy Korean shares before, but timing, access, and liquidity made ownership awkward.

Micron already gets US-market attention as a direct AI memory stock. SK Hynix trades below Micron on forward earnings, even after both stocks surged heavily.

South Korea is also pushing a huge semiconductor buildout with Samsung and SK Hynix.

--- 📌 The current state of the global memory market.

This market has 2 main layers: DRAM, which includes the memory used next to CPUs and AI GPUs, and NAND flash, which is the storage inside SSDs, phones, and data centers.

In DRAM, the market is extremely concentrated, with Samsung at 38.5%, SK hynix at 28.8%, and Micron at 22.4% in 1Q26, meaning the top 3 control about 90% of global DRAM revenue.

In HBM, which is a premium submarket inside DRAM, the AI-specific memory used beside Nvidia GPUs, SK hynix is the market leader, with 58% share in 1Q26, while Samsung and Micron each had 21%.

HBM, or High Bandwidth Memory, is a special form of DRAM built for extreme data movement.

The difference is physical design.

Normal DRAM chips usually sit on memory modules or near the processor, and data moves through relatively narrower connections.

HBM stacks multiple DRAM dies vertically and places them very close to the GPU through advanced packaging, which creates a much wider data path.

That wider path gives AI chips much higher memory bandwidth, meaning the GPU can receive data faster instead of sitting idle.
