Micron and SK Hynix Cross $1 Trillion Valuations as Chip Shortage Fuels AI Boom

Micron Technology and SK Hynix each reached a $1 trillion market valuation this week, joining Samsung as the only memory chip manufacturers to achieve this milestone. The surge reflects an unprecedented demand for high-bandwidth memory (HBM) chips, critical for powering AI accelerators in data centers, as supply struggles to keep pace with rapid expansion. Micron’s Q1 2026 financial results highlight the trend, with revenue climbing 56.6% year-over-year to $13.64 billion, while non-GAAP earnings per share reached $4.78. The company’s Cloud Memory Business Unit generated $5.28 billion in revenue, with a gross margin of 66%, nearly doubling from the prior year. Gross margin for the quarter expanded to 56%, up from 38.4% in the same period last year, driven by higher prices and constrained supply. Micron’s CEO, Sanjay Mehrotra, linked the company’s performance to the AI boom, emphasizing its role as an essential enabler for memory and storage needs. The company expects fiscal Q2 revenue of approximately $18.7 billion, with non-GAAP gross margins projected to hit 68%. Industry analysts note that HBM demand has outpaced production capacity, creating a bottleneck for AI infrastructure. Hyperscalers investing in AI clusters require massive amounts of HBM to support advanced accelerators, further tightening supply conditions. The trend underscores the critical role of memory chips in the AI-driven technology supercycle, benefiting leading manufacturers like Micron and SK Hynix.
