AI and Market Optimism Drive Micron to $1 Trillion Market Cap
Micron Technology's stock surged after UBS tripled its price target to $1,625, pushing the semiconductor maker toward a $1 trillion valuation. The rally was fueled by AI optimism and President Trump's praise for the company's U.S. investments. Other AI stocks, including Marvell Technology and Qualcomm, also gained ground on the news.
Micron Technology MU closed above a $1 trillion market capitalization for the first time in its history on May 26, 2026, after shares jumped 19.29% to $895.88 . The rally was triggered by UBS analyst Timothy Arcuri, who tripled his price target on the memory-chip maker to a Street-high $1,625 from $535, a level that would imply a roughly $1.8 trillion valuation .
UBS argued that investors should begin applying a more "normal" earnings multiple to Micron as AI demand reshapes the memory market, citing tighter supply of high-bandwidth memory (HBM) and long-term supply agreements as structural tailwinds . The move added to broader market optimism, lifting the Nasdaq and S&P 500 and pulling other AI-exposed semiconductor names higher , .
The scale of the re-rating leaves little margin for execution missteps: at a $1,625 target, Micron would trade well above historical memory-cycle multiples, and any softening in HBM pricing or AI capex could pressure the stock. Investors will watch Micron's next earnings report and HBM capacity commentary for confirmation that the AI-driven demand thesis is holding.
