Micron Shares Surge on Blockbuster Earnings Driven by AI Chip Demand

Micron Shares Surge on Blockbuster Earnings Driven by AI Chip Demand Micron’s meteoric rise from a low-profile memory supplier to a trillion‑dollar AI winner has upended tech markets, enriching investors while raising costs for consumers caught in a global chip squeeze.

In early 2024, Micron’s stock traded below $100, with a market value under $100 billion. As generative AI workloads exploded, demand for high‑bandwidth memory (HBM) and other system memory began to outstrip supply, setting up what analysts later dubbed a period of “RAMageddon” expected to last into 2027.

By Micron’s fiscal third quarter of 2026, the shortage had fully hit. The company reported that revenue had “quadrupled” year‑on‑year to about $41–42 billion, driven almost entirely by AI memory demand, with profits surging from roughly $1.9 billion to over $28 billion. Gross margins climbed above 81 percent as AI accelerators from Nvidia and Google turned HBM into the “binding constraint on AI infrastructure expansion.”

Investor reaction was immediate. After Micron posted what one outlet called a “15‑fold profit surge,” shares rallied in after‑hours trading on expectations of “sustained demand for computer memory.” The company’s stock then soared more than 236% in a single month, briefly pushing its market value to around $1.27 trillion and allowing it to “surpass the market valuation of Meta and Tesla” at one point before settling slightly below them.

Wall Street began branding Micron “the next Nvidia,” betting that long‑term supply deals and sold‑out HBM capacity would make its earnings more “durable” despite memory’s history of brutal boom‑bust cycles. Micron highlighted 16 strategic agreements, including a multi‑year deal with AI lab Anthropic covering HBM, DRAM, and SSDs alongside a strategic investment.

But the same crunch that is “paying off” for Micron is hurting device makers and consumers. Apple, for example, has linked looming product price increases to the “unprecedented” cost of memory chips, even as Micron’s blockbuster results “spark [a] Wall Street tech shake‑up.”

Micron now forecasts fourth‑quarter revenue of roughly $49–51 billion and has raised its capital spending plans above $25 billion to expand advanced DRAM and HBM production. Whether that investment averts the next painful downturn—or simply sets up a larger one—has become the central question for investors and the wider tech industry.
