Micron surges after UBS triples price target to $1,625 on HBM AI memory strength

Micron jumped as much as +19% on May 26 after UBS analyst Timothy Arcuri more than tripled his UBS price target from $535 to $1,625, the highest among 46 analysts. The rally pushed Micron above the ~$886.74/share level tied to a $1T market cap, with UBS implying a potential ~ $1.8T valuation within 12 months if the thesis holds. The core driver is AI memory. Micron is positioned for high-bandwidth memory (HBM), a critical input for AI accelerators used in large language models. The latest update adds that Micron has secured multi-year supply agreements, including partially fixed pricing in some deals, reducing reliance on historically more volatile spot-market memory pricing. Traders should focus on execution vs. competition. Micron is one of only three firms (Samsung, SK hynix, and Micron) able to produce HBM at scale. SK hynix leads HBM3E share today, while Samsung is investing in next-generation HBM production. The near-term question for Micron: can it maintain or grow HBM share as HBM4 timelines tighten? How this matters for trading: the market is leaning into an “AI memory bottleneck” narrative. If Micron can keep HBM supply effectively sold out through 2026 and beyond, sentiment could stay elevated; if market share or tech leadership shifts, the premium may compress quickly.
