Micron Technology deepened its commitment to U.S. semiconductor manufacturing on Thursday, unveiling an expanded domestic investment strategy worth approximately $250 billion through 2035 and announcing a series of supply-chain initiatives aimed at supporting the rapidly growing artificial intelligence market. Investors welcomed the move, sending the memory-chip maker's shares up about 7% after the announcement.
The latest gains add to an extraordinary rally for Micron in 2026. The company's stock has climbed more than 250% this year, propelled by surging demand for high-bandwidth memory (HBM) chips and other advanced memory products used in AI servers, hyperscale data centers and high-performance computing systems. Earlier this year, Micron surpassed a $1 trillion market capitalization, underscoring Wall Street's growing confidence that memory manufacturers will remain among the biggest beneficiaries of the AI infrastructure boom.
At the center of Thursday's announcement was a substantial increase in Micron's long-term U.S. capital commitment. The company said it now expects to invest roughly $250 billion domestically by 2035, approximately $50 billion more than previously planned. The additional spending reflects both rising customer demand and the industry's broader effort to strengthen domestic semiconductor production.
The investment package also includes up to $3 billion in strategic initiatives designed to reinforce critical parts of the U.S. semiconductor supply chain. One of the largest components is a $500 million investment involving Taiwan-based GlobalWafers, which will expand silicon wafer research, development and manufacturing operations at the company's facilities in Texas.
Micron also entered into a 10-year supply agreement with GlobalWafers, providing long-term access to silicon wafers, a foundational material used in semiconductor manufacturing. The agreement is intended to reduce supply-chain risks at a time when chipmakers continue to diversify sourcing following pandemic-era disruptions and increasing geopolitical tensions surrounding global technology production.
"Securing a reliable supply of critical input materials is essential to supporting Micron's long-term growth and technology roadmap," Ben Tessone, Micron's chief procurement officer, said in a company statement.
The company's manufacturing expansion extends well beyond supply-chain partnerships. Construction is already underway on two advanced memory fabrication plants at Micron's headquarters in Boise, Idaho, where the company aims to significantly expand domestic production capacity for next-generation memory chips.
Thursday also marked another milestone for Micron's New York expansion. The company announced that it had poured the first concrete for its fabrication facility in Clay, New York, a project Micron has described as the largest semiconductor manufacturing campus in U.S. history. Once completed, the facility is expected to become a major hub for memory-chip production while generating thousands of construction and manufacturing jobs over the coming decades.
