Micron said its planned U.S. fab and technology investment now exceeds $250 billion through 2035, as the memory maker starts the first concrete pour at its Clay, New York site.

Micron said the New York milestone came more than one quarter ahead of its original plan and moves the project from site preparation to vertical construction.

The company linked the larger investment plan to demand for memory in the AI era and to a long-term goal of producing 40% of its DRAM in the U.S.

Micron Raised Its U.S. Investment Plan Above $250 Billion

Micron said the expanded plan covers fab and technology investments across the U.S. through 2035.

The company said the increase reflects confidence in continued demand for leading-edge memory products, while the same announcement described the Clay project as the centrepiece of its domestic manufacturing plan.

Sanjay Mehrotra, Micron's chairman, president and chief executive, said the company is increasing its U.S. investments to more than $250 billion through 2035.

Commerce Secretary Howard Lutnick said the commitment would create nearly 100,000 jobs, while New York Governor Kathy Hochul referred to up to 50,000 jobs tied to the Central New York project.

Micron also said its U.S. manufacturing plan supports a long-term objective of producing 40% of its DRAM in the U.S. The announcement described that target as a domestic manufacturing objective and did not attach it to a disclosed customer order book.

The official release framed the investment as a memory-supply and manufacturing programme rather than a single-fab update.

The announcement did not provide a site-by-site spending split across New York, Idaho, Virginia, research and development, or other technology categories.

Clay Fab Moves From Site Work To Vertical Construction

The Clay site has completed key early works less than six months after breaking ground in January 2026, according to Micron.

The first concrete pour marks the start of vertical construction, and the company said Bechtel has been selected for engineering, procurement and construction management on the first two fabs.

Micron said approximately $675 million has been directed to New York-based contractors, suppliers and subcontractors to date, representing more than half of the total awarded value so far.

The company said more than 80% of workers on site to date have been New York residents.

The New York project could include up to four fabs.

Micron listed 50,000 expected New York jobs for the project, with 9,000 of those roles directly at Micron, alongside construction work for union trades, apprentices, local training graduates, specialty contractors and suppliers.

Idaho And Virginia Extend The Memory Manufacturing Plan

Micron said the New York site is the cornerstone of a wider U.S. investment plan.

Micron said the Idaho schedule puts first wafer output for the first fab in the middle of 2027 and the second fab near the end of 2028.

Virginia adds a different part of the memory roadmap.

Micron said it launched initial production of its 1-alpha DDR4 technology there earlier this year, supporting long lifecycle product needs in auto, industrial, medical, aerospace and defence markets.

Micron said the U.S. projects are expected to create more than 90,000 jobs.

The company said it would remain disciplined and responsive to the market environment as it aligns supply plans, and said capacity additions would depend on demand conditions as well as construction milestones.

Micron Has Not Named Customer Orders For The New Capacity

The announcement named public officials, contractors and community investment programmes, including Micron's recently announced $250 million investment in Trump Accounts for eligible children and families.

Senator Chuck Schumer said he delivered a $6.1 billion CHIPS grant and other federal support for the New York project.

Micron's announcement did not name signed customer orders for the new fabs, disclose production volumes by site, set utilisation targets, or provide a ramp date for the first New York wafer output.
