Micron shares rose 7% on Thursday as the company announced a new round of investments aimed at boosting the U.S. semiconductor supply chain, and plans to accelerate its spending in the country through 2035.
The new strategic investment of up to $3 billion includes $500 million for Taiwanese-headquartered GlobalWafers to expand its wafer development and manufacturing in its Texas facilities, and also comes with a 10-year supply agreement for raw silicon wafer capacity.
“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, in a press release.
In a separate announcement, the chipmaker said it will also raise its planned U.S. investment to $250 billion through 2035, roughly a $50 billion increase, as memory demand from the artificial intelligence buildout skyrockets.
Other names in the chip space rallied on Thursday, with Applied Materials, KLA Corp and Lam Research up 7%, and ARM Holdings up 11%.
Micron’s Thursday boost is the tip of the iceberg when it comes to its stock growth this year. Shares have rocketed more than 250% in 2026, with the chipmaker hitting a $1 trillion market cap for the first time back in May.
As they try to keep up with the soaring memory demand linked to running and processing AI workloads, Micron’s hefty U.S. investments have also brought new and expanded facilities in a handful of cities where it operates.
Construction is underway on two new fabs in the company’s Boise, Idaho headquarters, and on Thursday, the company poured the first concrete at its new Clay, New York fab.
Micron’s New York facility will be the largest semiconductor manufacturing site in U.S. history, the company said in a release.
