Investing.com -- SK Hynix's $26.5 billion Nasdaq debut on July 10, 2026—the largest U.S. listing ever by a foreign company and the second largest IPO in history—highlighted an obvious question: with AI investments breaking records and the HBM supercycle in full swing, does the Korean market-share leader, or its fierce U.S. competitor Micron, capture more of the upside?

With both companies central to the AI infrastructure buildout and, by extension, to high-stakes political powerplays, Investing.com did a deep dive to see how the two stack up across technology, valuation, and the new geopolitical reality.

**Demand far above supply**

The macro backdrop for both companies couldn't be clearer: for the foreseeable future, the demand is endless. UBS projects total memory industry revenues reaching $992 billion in 2026 and $1.76 trillion in 2027. The DRAM industry is expected to remain structurally undersupplied through at least 2028. That is not a near-term inventory cycle; it is a multi-year reshaping of the supply-demand curve.

SK Hynix CEO Kwak Noh-jung sharpened the picture in a July 10 interview: "We forecast that next year will be the worst year in the industry's history from the supply perspective. Our customer demand continues to go up, while our capacity has limitations. We still forecast that customer demand will remain higher than our supply capacity even beyond 2030". The candor from a sitting CEO to admit his company's inability to meet demand is unusual and reassuring at the same time. It is arguably bullish for pricing power across the entire sector.

**The HBM scoreboard**

On the current generation of high-bandwidth memory, SK Hynix holds a commanding position. The company controlled 56%-58% of the HBM market in Q1 2026, with Samsung and Micron roughly tied for second at about 21%-22% each. That lead is anchored by a close partnership with Nvidia, the dominant buyer of HBM chips for its AI accelerators. SK Hynix's HBM share, however, has declined from 69% a year earlier—a signal that competitors are narrowing the gap as Samsung begins HBM4 mass production and Micron expands its own HBM capabilities.

Micron reported fiscal Q3 2026 revenue of $41.46 billion, up 346% year-over-year, with EPS of $25.11, delivering a major beat across the board. The company's gross margin reached 84.9%. Those numbers reflect genuine pricing power and a customer mix shifting toward higher-margin HBM and data center DRAM.

**The valuation gap**

Here is where the comparison gets heated. Despite holding a 58% HBM market share and completing the largest foreign listing in U.S. history, SK Hynix trades at roughly 5.8 times forward earnings, versus Micron's 7 times. Micron commands a valuation premium even though it is a significantly smaller player by HBM share.
