SK Hynix Takes the Lead Over Micron in HBM Race

Key Points

• SK Hynix is the market share leader in high‑bandwidth memory (HBM) and recently partnered with Nvidia.

• Micron has a long track record with memory‑chip investors and has prospered in HBM despite entering the market later.

When Micron went public in 1984, it was not the only U.S. maker of DRAM, but over subsequent years other domestic DRAM producers exited the sector. As a result, Micron became the sole U.S.‑listed memory company until new competition emerged.

That changed this month.

SK Hynix listed its American depositary receipts on the Nasdaq Exchange on July 10, giving U.S. investors direct exposure to the memory market, especially the high‑bandwidth memory (HBM) segment that data centers now demand at scale. The question for investors is whether to favor SK Hynix or stay with Micron.

The case for SK Hynix

SK Hynix’s partnership with Nvidia gives it a distinct advantage, as sales of its HBM chips benefit from integration with the AI accelerator market leader. The Korean firm was the first to produce HBM in 2013 and still commands about 56 % of the market on which Nvidia depends.

Memory chip makers enjoy premium pricing while demand outpaces supply, but the sector is notoriously cyclical. Eventually supply will catch up, and pricing power could erode. SK Hynix’s leading market share could become a liability in a downturn.

Nevertheless, the market is not facing an immediate glut. In the most recent quarter, SK Hynix’s revenue surged 199 % year‑over‑year, following a 47 % increase in the prior full year. Net income rose 397 % YoY to $26.5 billion. The stock trades at a P/E of around 24, reflecting the sector’s volatility.

AI‑driven data‑center growth appears sustainable, and SK Hynix’s positioning in HBM places it in a strong spot for continued upside.

Why investors might still prefer Micron stock

Micron’s 42‑year listing gives it a well‑understood track record. As a U.S. company, investors can own its shares directly rather than through an ADR, which may be preferable to some.

Although Micron entered the HBM market later (2021) and trails SK Hynix in market share, it remains a key Nvidia supplier. Micron’s recent quarters have also shown robust growth: revenue jumped 346 % YoY in the most recent quarter, and net income increased nearly fifteenfold. Its P/E of about 20 suggests a lower valuation than SK Hynix.

Investors who tolerate sector volatility may still find Micron attractive for its brand recognition and direct U.S. listing.

SK Hynix or Micron?

For investors seeking exposure to the high‑bandwidth memory theme, SK Hynix’s market leadership and strategic tie‑up with Nvidia make it the more compelling choice. Micron offers a longer history and a lower valuation, but SK Hynix’s dominant position in a growth‑driven segment gives it a durable competitive edge.
