Micron Technology $MU crossed a $1 trillion market capitalization on May 26, 2026, after its stock jumped 19% in a single trading session - the company's biggest one-day gain since 2011. The move was triggered by a UBS analyst upgrade. UBS analyst Timothy Arcuri tripled his price target on the stock from $535 to $1,625, now the highest on Wall Street, arguing Micron is no longer a cyclical memory chipmaker subject to boom-bust pricing but rather an AI infrastructure company signing long-term supply agreements with hyperscalers. Micron holds approximately 21% of the global high-bandwidth memory market, competing with South Korea's SK Hynix and Samsung. All three firms' 2026 HBM capacity is sold out, and Micron's CEO confirmed the company can fulfil only 50-65% of medium-term customer demand. Micron's market capitalization grew from approximately $108 billion in May 2025 to roughly $1.01 trillion in May 2026. Source: CNBC, May 26, 2026.
