Micron's new $50 billion investment will be added to its previous $200 billion commitment, with related projects spanning multiple facility construction plans in New York, Idaho, and Virginia. Total expenditures are expected to continue through 2035. Meanwhile, Micron stated it will separately allocate $3 billion to strengthen the domestic semiconductor supply chain.
Micron Technology has significantly increased its commitment to building factories in the United States and is collaborating with silicon wafer suppliers to develop a domestic supply chain, reflecting the explosive growth in demand for memory chips driven by the AI infrastructure boom.
Micron Technology announced on Thursday that it is increasing its previously disclosed U.S. domestic production expansion plan to $250 billion, an addition of $50 billion over its original commitment. Following the U.S. stock market open today, memory-related stocks surged across the board, $Micron Technology (MU.US)$ 、 $Western Digital (WDC.US)$ 、 $Seagate Technology (STX.US)$ rose more than 7%. $SanDisk (SNDK.US)$ Rising more than 5%.
Meanwhile, Micron stated it would allocate an additional $3 billion to strengthen the domestic semiconductor supply chain, including providing a $500 million strategic investment to Taiwan-based silicon wafer supplier GlobalWafers Co. The two companies also signed a ten-year raw material supply agreement aimed at securing critical raw materials for Micron’s long-term manufacturing plans.
Investment scale expanded to $250 billion, with projects extending through 2035
Micron’s newly added $50 billion investment will be layered on top of its previous $200 billion commitment. The related projects include multiple fab construction plans across New York, Idaho, and Virginia, with total expenditures expected to continue through 2035.
Micron attributes this large-scale expansion to the "unprecedented demand" generated by the rapid build-out of AI infrastructure. As investments in AI computing power continue to intensify, demand for high-bandwidth memory chips has surged sharply, placing pressure on both Micron and its competitors to accelerate capacity expansion.
Securing silicon wafer supply: Ten-year agreement strengthens domestic supply chain
Within the $3 billion allocated for supply chain investments, Micron’s $500 million strategic investment in GlobalWafers has drawn particular attention. The ten-year agreement between the two parties will ensure Micron access to "significant silicon wafer capacity," supporting its long-term manufacturing roadmap and reinforcing the U.S. semiconductor manufacturing ecosystem.
Ben Tessone, Senior Vice President and Chief Procurement Officer at Micron, stated in a press release that this strategic investment demonstrates Micron’s commitment to enhancing supply security, deepening collaboration with key suppliers, and supporting the expansion of the U.S. semiconductor supply chain and manufacturing infrastructure. Both parties also expressed their willingness to collaborate on next-generation wafer technologies.
Memory chip giants race to expand capacity amid industry-wide investment surge
Micron's capacity expansion move is not an isolated case.
Last week, Samsung Electronics and SK Hynix jointly disclosed that the two South Korean memory giants plan to invest a combined total of up to USD 880 billion in projects including new wafer fabrication plants. This series of substantial capital expenditures underscores a new round of an arms race in the global memory chip industry, driven by surging demand from artificial intelligence.
Meanwhile, SK Hynix is reported to have priced its U.S. share offering at a level 3.1% above its closing price in Korea, reflecting continued strong investor appetite for memory chip stocks in capital markets.
This expansion plan also aligns with the U.S. government's policy objective of bringing semiconductor manufacturing back onshore. The CHIPS and Science Act was enacted in 2022 under the Biden administration and subsequently amended after President Trump took office. Micron Technology is among the beneficiaries of this legislation, alongside Intel and Taiwan Semiconductor. Micron’s significant upward revision of its investment commitment further solidifies its strategic position within the U.S. domestic semiconductor manufacturing landscape.
