Is SK Hynix stock a better pick to play AI memory market than Micron?

South Korean semiconductor giant SK Hynix made history on Wall Street, listing on Nasdaq today via American Depositary Receipts (ADRs) under the ticker SKHY.

The firm’s US initial public offering (IPO) priced at $149 was more than 7x oversubscribed – and raised a total of about $26.5 billion. This made it the largest-ever US listing by a foreign company.

SK Hynix stock is now better-positioned to compete for capital against its American rival, Micron. But is it really a better investment than MU for the long-term? Let’s find out!

SK Hynix stock owns the HBM market

SKHY shares may be a superior investment than Micron due to the company’s absolute dominance on the High-Bandwidth Memory (HBM) market.

The South Korean giant commands an impressive 56.4% share of the global HBM sector – which makes it the primary supplier of ultra-fast memory for artificial intelligence (AI) accelerators.

In fact, SK Hynix is already deeply integrated into Nvidia’s next-generation Vera Rubin platform with its advanced HBM4 architecture.

While Micron Technology is executing rather well and has sold out its capacity through the end of this year, it controls a much smaller 21% market share.

SK Hynix’s massive volume footprint grants it unparalleled pricing power and stronger, contracted multi-year revenue visibility with hyperscalers.

SKHY shares are more attractively priced than MU

In terms of profitability, SK Hynix shares seem to be in a whole another league.

In its latest reported quarter, the company’s operating margin stood at a staggering 72%, driven by high-value enterprise solid-state drives (eSSDs) and premium DRAM modules.

However, despite this world-class financial efficiency, a notable valuation disconnect persists. SK Hynix trades at a highly attractive forward price-to-earnings (P/E) multiple of just 8x, which makes it infinitely cheaper to own than Micron.

In other words, SKHY offers investors direct exposure to the booming artificial intelligence memory market at a much lower valuation than MU.

Here’s why it isn’t too late to invest in SK Hynix

Despite significant market debut gains, SKHY stock remains attractive as a long-term holding also because the company plans of using the IPO proceeds to future-proof its production moat.

Executives have earmarked substantial funds for extreme ultraviolet (EUV) lithography equipment and advanced packaging plants, including the Yongin semiconductor cluster.

This positions SK Hynix to significantly benefit as the global tech infrastructure shift from massive foundational model training toward real-time, continuous inference driven by agentic AI.

All in all, Icheon-headquartered SK Hynix Inc combines unrivaled HBM leadership, impressive profitability, compelling valuation, and an aggressive capacity expansion strategy all into one.

While Micron Technology remains a formidable competitor, SKHY appears better positioned to capture the next phase of AI-driven semiconductor demand, making it a more compelling long-term investment for growth-oriented investors in 2026.
