More than $250 billion is now earmarked by Micron for U.S. investment through 2035, up from an original $170 billion plan and a $200 billion target set in June.
AI-driven demand for DRAM, NAND and high-bandwidth memory is behind the expansion, with Micron saying shortages in memory and storage chips could take considerable time to ease even as supply improves gradually in 2028.
A $3 billion commitment to GlobalWafers' Texas silicon-wafer operations and a planned 10-year supply deal are meant to secure raw wafer capacity for Micron's AI memory production.
Micron's latest results underscored the boom: third-quarter gross margin rose to 84.9% from 74.9% in the prior quarter, and the company forecast about $50 billion in fiscal fourth-quarter 2026 revenue, plus or minus $1 billion.
The spending push deepens Micron's role in the AI supply chain, where its HBM is used by customers including Nvidia and AMD as hyperscalers keep raising AI infrastructure budgets.

Micron’s $250 Billion Bet: Transforming U.S. Semiconductor Manufacturing for the AI Era
Overview
Micron is making major investments to strengthen the U.S. semiconductor supply chain, driven by a surge in AI demand for advanced memory like DRAM. By deepening its partnership with GlobalWafers and committing up to $3 billion in strategic investments, Micron aims to secure essential materials and boost domestic manufacturing resilience. The company’s first fabrication plant in Idaho, set to produce DRAM by 2027, is timed to meet the growing needs of decentralized AI networks and high-performance computing. These efforts position Micron at the forefront of supporting the expanding AI infrastructure in the United States.
