Micron accelerates global capacity expansion: $9.3 billion Hiroshima plant breaks ground in Japan, AI memory production targets 2028
BlockBeats News, July 5 — Micron is making an all-out effort to expand global production capacity to address the severe shortage of AI-driven HBM, DRAM, and NAND memory. The company expects tight supply to continue until after 2026, with new capacity gradually coming online starting in 2027, involving substantial overall investment. Details include:
Heavy investment in the US
· The Manassas plant in Virginia achieved 1α nm process mass production in May 2026. The $2 billion expansion project will quadruple DDR4 wafer supply, focusing on automotive, defense, and industrial sectors, with support from the CHIPS Act subsidy.
· In Boise, Idaho, an investment of about $50 billion is underway to build next-generation plants, with groundbreaking completed. The first plant is expected to go into production in mid-2027. Recently, the company further increased total US investment to approximately $200 billion (manufacturing + R&D), including a new second fab.
· The megafab project in Clay, New York, worth tens of billions of dollars, is steadily advancing, with plans for multiple wafer fabrication plants and a target of large-scale production around 2030.
Simultaneous expansion in Asia
· In early July, Hiroshima, Japan held a groundbreaking ceremony for a ¥1.5 trillion (about $9.3 billion) expansion focused on high-end HBM and other AI chips, with shipments expected around 2028. The Japanese government is providing substantial subsidies.
· Singapore: Construction of a $24 billion advanced NAND wafer fab began in January, scheduled to start production in the second half of 2028.
· Taiwan: Acquired the Powerchip Tongluo wafer fab for $1.8 billion, aiming to begin DRAM production in 2027.
Micron emphasized that this capacity expansion is mainly to meet long-term demand and localize the supply chain, not for a short-term significant increase in consumer-grade supply. Analysts believe the overall DRAM/NAND shortage is unlikely to change in the short term, and prices remain supported. This round of global expansion is expected to significantly boost Micron’s production capacity and create tens of thousands of jobs. The company aims to produce about 40% of its DRAM in the US by around 2030. More updates will follow as AI demand continues to evolve.

Goldman Sachs believes that the rapid rise in real interest rates has exerted more direct pressure on the US stock market, with rate-sensitive sectors such as small-cap and financial stocks being particularly affected. On the liquidity front, Goldman Sachs estimates that pension funds may sell around $3.3 billions in equities at the end of the month and quarter, and that CTAs may sell about $530 million worth of Russell 2000 index futures in the coming week.
