For years, Micron Technology, Inc. (NASDAQ:MU) was the go-to stock for U.S. investors looking to ride the AI memory boom. Now, it has company. SK hynix Inc‘s (NASDAQ:SKHY) recent Nasdaq debut has brought one of the world’s largest memory chipmakers directly to U.S. investors, setting up a fresh rivalry between two companies at the center of the artificial intelligence infrastructure buildout.
Two Nvidia Suppliers, One AI Opportunity
Both companies are key suppliers of high-bandwidth memory (HBM), the specialized chips powering Nvidia Corp.‘s (NASDAQ:NVDA) latest AI accelerators.
Both are benefiting from soaring demand for AI servers. Both have become trillion-dollar companies. And both are investing aggressively to expand production as hyperscalers race to build more AI infrastructure.
The question for investors is no longer whether AI memory is a compelling theme. It’s which stock offers the better way to play it.
How the Valuations Compare
At first glance, the two companies look more evenly matched than many investors might expect.

*P/E figures for SKHynix calculated using publicly available EPS and market data, as Benzinga Pro does not currently display these metrics for this comparison.
The comparison shows just how closely the market is valuing the two AI memory leaders. Micron trades at a slightly lower trailing earnings multiple and price-to-sales ratio, while SK Hynix carries the lower EV-to-EBITDA multiple.
Where Micron Has the Edge
Micron remains one of Wall Street’s strongest AI momentum stories.
According to Benzinga Edge Rankings, the company scores 99.62 for Momentum, 97.77 for Quality and 84.67 for Growth, reflecting both strong execution and investor enthusiasm around AI-driven memory demand.
Its Value score of 27.85, however, suggests investors are already paying a premium for that growth story.
What SK Hynix Brings to the Table
SK Hynix arrives on Nasdaq with a different advantage.
The company is widely viewed as the global leader in high-bandwidth memory and has established itself as one of Nvidia’s most important HBM suppliers. Its U.S. listing gives American investors direct access to that business without buying shares on the Korea Exchange.
While Benzinga Edge rankings are not yet available following the company’s U.S. listing, its valuation metrics suggest investors are assigning a premium comparable to Micron’s rather than treating it as a discounted alternative.
The AI Memory Trade Just Got More Competitive
SK Hynix’s Nasdaq debut isn’t just another semiconductor IPO. It expands the investment universe for one of AI’s fastest-growing markets.
Micron still offers the familiarity of an established U.S.-listed AI winner with strong momentum and a forward earnings multiple of roughly 6.3x.
SK Hynix, meanwhile, gives investors exposure to one of the industry’s dominant HBM manufacturers at valuation levels that are remarkably similar to Micron’s.
For investors, that may be the biggest takeaway. The AI memory trade is no longer a one-stock story. It has become a two-stock debate, with Wall Street now weighing whether execution, valuation or market leadership will matter most as AI spending enters its next phase.
