Micron Technology (NASDAQ: MU) has poured the first concrete at its semiconductor manufacturing site in Clay, New York, a construction milestone the company says was reached more than one quarter ahead of the original schedule. The event marks the transition from site preparation to vertical construction, less than six months after the project broke ground in January 2026.

Alongside the milestone, Micron raised its planned U.S. investment to more than $250 billion through 2035, up from a prior commitment, citing demand for memory products used in artificial intelligence applications. The company said it also plans to invest up to $3 billion to develop the domestic semiconductor supply chain.

Micron said the Clay site, which could include up to four fabrication facilities, is the largest private investment in New York State history. The project is expected to generate 50,000 jobs in New York, including 9,000 direct Micron positions. Across all U.S. sites, the company projects more than 90,000 jobs.

To date, Micron and site infrastructure contractor Gilbane Building Company have directed approximately $675 million — more than half of the total awarded value — to New York-based contractors, suppliers, and subcontractors. More than 80% of workers on site have been New York residents, according to the company.

Micron selected Bechtel as the engineering, procurement, and construction partner for the first New York fab. Jacobs serves as architectural and engineering design partner.

The company's U.S. manufacturing footprint also includes sites in Idaho, where first wafer output is expected in mid-2027 for the first fab and late 2028 for the second, and Virginia, where Micron launched initial production of its 1-alpha DDR4 technology earlier this year.

Micron said it targets producing 40% of its DRAM in the United States as a long-term goal. The company also announced a $250 million investment in Trump Accounts, offering a one-time $250 seed deposit for eligible children in communities where it operates, and has committed more than $50 million to community priorities across Central New York.
