Micron Joins Trillion-Dollar Club as AI Memory Demand Fuels Rally; MU Surges

Micron Technology Inc. (MU) surpassed $1 trillion in market value for the first time on May 26, 2026, as the artificial intelligence boom drives insatiable demand for high-bandwidth memory (HBM). The milestone ignited a broad rally across memory stocks and related ETFs. President Trump publicly endorsed the company, and UBS analysts doubled their price target. The surge highlights the intensifying global competition for advanced memory chips critical to AI data centers. Micron’s ascent follows record earnings fueled by premium pricing for its HBM3E products.
