Micron Technology briefly crossed a $1 trillion market value on May 26, 2026, after its shares jumped 17.4% to $881.6. At one point in the session, the stock was up as much as 19.3%, putting the U.S.'s largest memory chipmaker in rare company.
The move is why investors were searching for Micron's mu stock price on Tuesday: UBS lifted its price target to $1,625 from $535, the highest among 46 brokerages covering the company, and that call landed as the market kept rewarding memory makers tied to artificial intelligence demand. Art Hogan said the demand environment for pure memory had increased rapidly and that Micron “sits at the center” of that shift.
Micron's rise has not come out of nowhere. Its shares have climbed more than eightfold over the past 12 months, powered by strong earnings and a supply backdrop that has tightened just as data center demand has accelerated. The company operates four business units — Compute and Networking, Mobile, Embedded and Storage — but the market is focusing most on the memory pieces that feed AI systems.
That is also where the friction lies. said Micron's 2026 high-bandwidth memory supply is already sold out, even as its next-generation HBM4 chips have entered production. In other words, the stock has raced ahead on expectations that supply will stay scarce, but the market is also staring at how much capacity can be added and how long the current imbalance can last.
For now, the valuation milestone tells the story: investors are treating Micron less like a cyclical chipmaker and more like a critical supplier to the AI buildout. The next question is whether the company can keep turning that scarcity into earnings fast enough to justify a price target that now sits far above where the stock traded only months ago.
