Micron Technology (MU) stock climbed 7% on Thursday after the company unveiled a sweeping expansion of its U.S. manufacturing footprint, raising its planned domestic investment to more than $250 billion through 2035.

BREAKING: Micron, $MU, announces plans ​to invest ​up ​to $3 billion to ‌”strengthen ⁠the US ​semiconductor ​supply-chain ⁠ecosystem.”

Micron also raises its planned US investment to over $250 billion through 2035, which it expects to create over 90,000 jobs.

That figure is up roughly $50 billion from previous guidance, with the increase driven by surging memory chip demand tied to the AI buildout.

MU stock was trading around $1,017 on Thursday, up $68 on the session.

The company also announced a separate $3 billion commitment to strengthen the U.S. semiconductor supply chain.

Of that, $500 million will go to GlobalWafers — a Taiwanese-headquartered company — to expand its 300mm silicon wafer facility in Sherman, Texas. The deal includes a 10-year supply agreement to lock in domestic wafer capacity for Micron’s future production.

“Securing a reliable supply of critical input materials is essential to supporting Micron’s long-term growth and technology roadmap,” said Ben Tessone, Micron’s chief procurement officer.

New York Fab Breaks Ground Ahead of Schedule

One of the headline moments in the announcement was the first concrete pour at Micron’s fabrication plant in Clay, New York — a milestone that arrived more than a quarter ahead of schedule.

The New York site is expected to eventually house up to four fabrication plants. Micron says it could become the largest semiconductor manufacturing site in U.S. history.

The project is projected to create around 50,000 jobs total, including 9,000 direct positions.

Combined with facilities in Idaho and Virginia, Micron expects its full U.S. expansion to generate more than 90,000 jobs.

DRAM Production Target

Micron’s long-term goal is to produce 40% of its DRAM memory chips domestically. The expanded investment is designed to help close that gap by scaling up manufacturing and reducing reliance on overseas suppliers.

The broader chip sector got a lift from the news. Applied Materials, KLA Corp, and Lam Research each rose around 7% on Thursday. ARM Holdings led the group, jumping 11%.

The investments align with Washington’s ongoing push to localize semiconductor production and build out a more resilient domestic supply chain.

Micron’s New York fab transition from site preparation to vertical construction marks the most concrete sign yet of that strategy moving from announcement to reality.
