Micron Technology just did something that would have sounded absurd two years ago. The memory chipmaker crossed $1 trillion in market capitalization on May 26, closing at approximately $895.88 per share after a roughly 19% single-day surge.
That’s the company’s best single-day performance since 2011. And it places Micron, a company once considered a cyclical commodity play, in the same rarefied air as Apple, Microsoft, and Nvidia.
The numbers behind the surge
The catalyst was a combination of analyst upgrades and accelerating demand for high-bandwidth memory chips used in AI training and inference workloads. UBS raised its price target on Micron from $535 to $1,625 on the same day, a record on Wall Street. That’s not a modest bump. That’s a full-throated declaration that the memory market is undergoing a structural transformation.
Micron’s stock has now more than tripled year-to-date in 2026. Over the trailing 12 months, shares have climbed approximately 700%. For context, that means someone who bought $10,000 worth of Micron stock a year ago is now sitting on roughly $80,000.
