Micron Technology stock hit an all-time closing high of $1,133.99 on June 18, 2026, as artificial intelligence memory demand continues to accelerate far beyond the company’s ability to produce chips. The memory chipmaker’s surge reflects a historic shortage of both DRAM and high-bandwidth memory (HBM) used in data centers training and running AI models.
The stock has gained 293% year-to-date in 2026, with Micron’s management recently disclosing that its entire HBM capacity for the year is already sold out. This sold-out status, combined with soaring prices for memory chips, has driven both revenue and profit expectations to record levels ahead of the company’s earnings report on June 24.
Micron’s revenue trajectory shows the scale of the AI-driven demand surge. In the second quarter of fiscal 2026, the company generated $23.9 billion in revenue. For the current quarter, Micron expects $33.5 billion—a 40% sequential jump. Wall Street analysts are forecasting even higher revenue of around $41 billion for the next quarter, according to The Motley Fool, suggesting the memory shortage will persist well into 2027.
The company manufactures two primary types of memory: DRAM for high-speed computing and NAND for long-term storage. Both are in acute short supply due to massive data center spending by cloud providers building AI infrastructure. Micron’s production capacity has been essentially fully booked this year, with no slack to meet additional demand.
Micron’s path to increased supply remains constrained. The company is working to bring its new Idaho facility online by mid-2027, but that timeline leaves the shortage intact for another 12 months. Even once capacity expands, data center capital spending is expected to rise again in 2027, according to analysis from The Motley Fool, which would further stretch available supply.
The memory chipmaker reached a $1 trillion market valuation in May 2026, a milestone that underscores how central Micron has become to the AI infrastructure build-out. A year earlier, the company was worth roughly $70 billion—making the scale of the rally one of the largest in semiconductor history.
Analyst price targets have widened significantly as expectations diverge on how long the memory supercycle will sustain. Some forecasts range as low as $155, while others exceed $1,500, reflecting genuine disagreement about whether AI demand can justify the company’s current valuation or whether the shortage will eventually ease and compress margins.
