Micron Builds New AI Memory Capacity in Idaho
During Micron’s fiscal third-quarter 2026 earnings call, CEO Sanjay Mehrotra confirmed that the company’s new Boise facilities are progressing according to schedule. The ID1 facility is expected to produce its first wafers in mid-2027, while the ID2 facility is projected to begin production in late 2028.
The two semiconductor fabs represent one of Micron’s largest investments in U.S. manufacturing capacity. The company plans to add approximately 3,500 direct jobs at the Boise sites, expanding from its current workforce of around 7,000 employees in the region.
Micron has also acknowledged the broader staffing challenge involved in the expansion, noting that future operations could require a workforce of up to 17,000 jobs. The project is supported by up to $6.2 billion in CHIPS Act funding, alongside Micron’s planned $100 billion semiconductor campus in Clay, New York.
AI Demand Drives Semiconductor Investment
Micron’s expansion is tied closely to the rapid growth of artificial intelligence infrastructure. High-bandwidth memory is essential for AI accelerators because it allows processors to access large amounts of data quickly during complex workloads.
The company expects significant capital spending as it builds new capacity. Fiscal 2026 capital expenditures are projected at approximately $27 billion, including around $10 billion in the fourth quarter alone.
However, Micron CEO Sanjay Mehrotra highlighted several challenges affecting semiconductor expansion, including long construction timelines, shortages of workers with specialized trade skills, regulatory requirements and the need for additional energy infrastructure.
Micron Stock Creates New Wealth in Idaho
Micron shares have experienced significant gains, increasing more than 200% year to date and rising substantially over the previous year. The stock performance has created major wealth effects among employees and local investors who hold company shares.
Boise wealth manager JT Belnap described the experience of one client who gained approximately $1 million in stock value over eight trading days due largely to holdings in Micron.
