Micron Technology’s meteoric rise strains tech giants and raises skepticism

Micron Technology reported $41.46 billion in fiscal Q3 2026 revenue, quadrupling year-over-year and beating estimates, as its stock surged more than eightfold in a year amid AI-driven demand for high-bandwidth memory chips. However, short interest has climbed to 37.3 million shares, signaling skepticism about the sustainability of the rally in the cyclical memory chip industry.

Micron Technology’s meteoric rise strains tech giants and raises skepticism The memory chipmaker's stock has surged more than eightfold in a year, but rising short interest suggests not everyone is buying the narrative A company best known for making the memory chips inside your laptop just posted quarterly revenue that quadrupled year-over-year. Micron Technology reported $41.46 billion in fiscal Q3 2026 revenue, blowing past the $35.84 billion Wall Street consensus. Shares surged 15% in after-hours trading following the June 24 earnings release, capping a run that has seen Micron’s stock increase more than eightfold over the 12 months ending late May 2026. The company’s market capitalization briefly flirted with $1 trillion. The AI memory gold rush The large language models and generative AI systems filling data centers worldwide need high-bandwidth memory HBM chips, and Micron happens to be one of the few companies on the planet that can make them at scale. Nvidia, a key customer of Micron’s HBM products, relies on Micron’s memory during a period of supply constraints that gives Micron significant pricing power. That pricing power showed up in the numbers. Micron’s gross margins hit 84.6% in Q3 2026. Adjusted earnings per share came in at $25.11, comfortably beating estimates. The performance prompted UBS to raise its price target on Micron to $1,625, a move that had already triggered a 19% single-day gain on May 26 when the upgrade was announced. The skeptics have receipts Short interest in Micron has climbed to 37.3 million shares, a signal that a meaningful cohort of investors is betting the rally has overshot reality. The memory chip industry is famously cyclical. Periods of explosive demand and sky-high pricing have historically been followed by supply gluts, margin compression, and painful corrections. It’s happened before with DRAM and NAND flash. Micron’s competitors aren’t standing still. SK Hynix, the South Korean memory giant and Micron’s primary rival in the HBM space, has experienced its own remarkable market gains, with its market cap also surpassing $1 trillion.
