Micron Technology has achieved a market capitalization exceeding $1 trillion for the first time, joining an exclusive group of tech giants like Nvidia and Apple. The memory chipmaker's stock surged up to 19% on May 26, closing at approximately $891, following a significant upgrade from UBS, which raised its price target from $535 to $1,625. This upgrade was driven by the soaring demand for high-bandwidth memory (HBM), crucial for AI accelerators in data centers. Micron's HBM capacity is fully booked through 2026, with recent quarterly revenues nearing $2 billion, reflecting strong sales of its HBM3E products and the upcoming HBM4 rollout. Despite the milestone, Micron faces competition from SK Hynix and Samsung, both advancing their HBM4 technologies. The company's ability to sustain its market position will be critical as it navigates this competitive landscape.
