The global artificial intelligence boom is fueling demand for memory chips, and Micron Technology is betting $250 billion that it can feed that hunger by building plants on American soil.
The explosive growth of generative AI has created an insatiable appetite for high-bandwidth memory (HBM), a specialized DRAM that enables rapid data transfer between GPUs and memory. Micron's HBM3E chips are integral to Nvidia's H200 and B200 AI accelerators, and the company's expanded U.S. production capacity will help meet this demand while reducing supply chain risks from geopolitical tensions in Asia.
Micron's new plan covers spending on U.S. factories through 2035. The extra cash comes as the AI boom pushes demand for high-end memory chips used in data-center processors. That same demand caused a worldwide memory shortage that has hit consumer electronics and car manufacturing.
CEO Sanjay Mehrotra said, "The investment will create more than 90,000 jobs" and "help ensure the leading-edge technologies shaping the future are built right here in the United States." Micron wants to make 40% of its DRAM products in the U.S. within ten years.

To get there, Micron is also spending $3 billion to secure domestic semiconductor supply chains. A chunk of that - $500 million - goes to GlobalWafers, a Taiwanese company that supplies the raw silicon wafers chips are built on. Micron's top procurement official Ben Tessone said the action "reflects our commitment to strengthening supply assurance, deepening collaboration with key suppliers, and supporting the expansion of the semiconductor supply chain and manufacturing infrastructure in the United States."
Micron isn't the only chipmaker going all in. South Korean rivals Samsung and SK Hynix have planned a combined $880 billion in investments over several years. SK Hynix is planning a U.S. stock exchange listing that might generate close to $27 billion, according to its most recent closing price in Seoul.
The federal government has prioritized expanding domestic semiconductor production capacity since the passage of the 2022 Chips and Science Act - originally enacted under President Biden and later amended after Donald Trump returned to the White House. Commerce Secretary Howard Lutnick attended an event near Syracuse, New York, where he said, "amazing companies are just investing massively in America, and of course, Micron being right at the top of the heap."
The push to onshore semiconductor production reflects growing concerns over supply chain vulnerabilities, particularly given the concentration of advanced chip manufacturing in Taiwan and South Korea. The U.S. Chips and Science Act, which provides subsidies and tax credits for domestic fabs, has accelerated such investments. Micron's plans align with a broader national strategy to secure critical technology components as geopolitical risks in the Asia-Pacific region persist.
Investors have already rewarded Micron.
Meanwhile, SK Hynix's potential U.S. listing could bring another wave of capital into the memory sector.
