# Micron invests $200 billion to expand its AI memory business

Micron Technology (Nasdaq: MU) will invest approximately $200 billion over the next few decades to expand memory manufacturing capacity, with a focus on domestic production in the United States, as AI demand has made memory a system-level bottleneck. This expansion plan includes building out a leading-edge fab in Boise, Idaho, where Micron will invest about $50 billion to more than double the size of its 450-acre campus and construct two new chip factories, expected to be operational by 2028. Additionally, Micron is developing a multi-fab complex in New York, which the company says could involve up to $100 billion in investment over more than 20 years.

Internationally, Micron is also expanding. The company announced a $9.6 billion investment in Hiroshima, Japan, to support the production of advanced AI memory, with construction expected to begin in May 2026 and shipments planned to start in 2028.

This scale reflects a fundamental shift in demand. High-bandwidth memory (HBM), used in conjunction with AI accelerators, has become one of the fastest-growing segments in the semiconductor industry. Each GPU in an AI server may require multiple advanced HBM stacks, increasing the memory capacity per system and exacerbating industry supply tightness, which has driven up DRAM pricing trends.

This is not a short-term expansion. Building and qualifying a memory fab takes years. With such massive capital outlays, Micron is preparing for long-term AI infrastructure build-out. The market has already reflected this optimism. Micron's stock price has risen 44.23% year-to-date and a staggering 331.75% over the past year.

Why might this AI stock be 2026's biggest surprise?
