Micron Technology commits $250 billion to US expansion as AI memory demand reshapes chip industry

Micron Technology Scales US Investment to $250 Billion

Micron Technology revealed plans to invest more than $250 billion in the United States through 2035, marking a roughly $50 billion increase from its previous commitment 2

. The expanded Micron investment plan aims to achieve 40% of DRAM output on US soil while addressing surging AI memory chip demand across data centers and cloud infrastructure. Chairman, President and CEO Sanjay Mehrotra announced the commitment at an event in Clay, New York, where the company marked the first concrete pour at its new fabrication facility—a milestone reached more than one quarter ahead of schedule 3

.

The announcement sent Micron shares climbing to an intraday high of $1,035.50, representing a gain of as much as 9.1% on the session, with the stock more than tripling in value year to date 3

3

. Commerce Secretary Howard Lutnick emphasized the strategic importance, stating that Micron's commitment would create nearly 100,000 jobs while providing leading-edge memory supply domestically 2

2

. The broader domestic manufacturing buildout is projected to support more than 90,000 jobs across construction, semiconductor manufacturing, and supply-chain roles 3

Hiroshima Factory Expansion Targets High-Bandwidth Memory Production

Separately, Micron Technology broke ground on a ¥1.5 trillion, approximately $9.3 billion, Hiroshima factory expansion focused on High-Bandwidth Memory production 1

. The Boise, Idaho-based chipmaker will use the site to produce the stacked DRAM that sits next to GPUs inside AI accelerators from Nvidia and other customers, with commercial shipments expected to begin around summer 2028 1

. Japan's Ministry of Economy, Trade and Industry (METI) has committed up to ¥500 billion, roughly $3.1 billion, toward the project's capital costs 1

. Including research and development support already pledged, the government's backing for Micron's Japanese operations now totals roughly ¥775 billion, covering close to half of the new investment 1

Mehrotra noted the symbolic significance of the location during the groundbreaking ceremony, revealing that Micron's first HBM production wafer was made at this same Hiroshima, Japan site—the piece of memory technology now sitting at the center of the AI buildout 1

. The facility already serves as one of Micron's most advanced DRAM manufacturing sites after the company introduced EUV lithography into production in 2024, enabling the transition from its 1-beta DRAM process to the more advanced 1-gamma node 4

AI Chip Shortage Drives Urgent Capacity Expansion

The investments reflect a binding constraint across the industry: Micron can currently fulfill only between half and two-thirds of customer orders for HBM, with its entire 2026 output already sold out under multi-year contracts 1

1

. High-Bandwidth Memory has become critical for AI accelerators and high-performance GPUs due to its exceptionally high bandwidth and energy efficiency, making it indispensable as AI infrastructure deployment accelerates worldwide 4

4

. Micron is only one of three companies globally that can manufacture HBM at scale, alongside Samsung and SK Hynix 1

.

The company reported fiscal third-quarter results that cleared analyst targets on nearly every key measure, projecting that the memory-chip shortage will persist past 2027 3

3

. This supply constraint is already affecting consumer electronics makers, who have begun absorbing the cost of the DRAM shortage as manufacturers redirect wafer capacity toward the higher margins that HBM commands 1

1

. Industry forecasts suggest Micron could eventually account for roughly one-quarter of the HBM market while representing approximately 20% of total HBM shipments 4

Strengthening the Semiconductor Supply Chain

Micron outlined plans to direct up to $3 billion toward strengthening the US semiconductor supply chain, with $500 million earmarked as strategic financing for GlobalWafers, a silicon wafer maker based in Taiwan, to scale up production capacity at its Texas operations 3

. Under the deal, GlobalWafers would supply Micron with raw silicon wafers over a decade-long contract tied to the company's long-term US semiconductor manufacturing plans 3

.

The New York facility near Syracuse is expected to become the largest private investment in the state's history and the largest semiconductor manufacturing site in US history 2

. With up to four fabrication plants planned, the project is projected to generate 50,000 jobs in New York, including 9,000 direct Micron positions 2

. Less than six months after breaking ground in January 2026, Micron has directed approximately $675 million to New York-based contractors, suppliers, and subcontractors, with more than 80% of on-site workers drawn from New York residents 2

Competitive Landscape and Strategic Positioning

Competition within the HBM market remains intense, with SK Hynix currently holding the leading position and supplying much of the HBM used by Nvidia's AI accelerators, while Samsung continues expanding its own production capabilities 4

4

. Both rivals have been producing HBM at scale for longer than Micron and are running their own expansion programs, meaning the competitive map could look considerably different by the time Hiroshima's new lines are shipping at volume in 2028 1

1

. Construction is also advancing at Micron's Idaho facilities, with first wafer output expected from its first Idaho fab in mid-2027, followed by production from a second fab in late 2028 2

2

. In Virginia, Micron has already started initial production of its 1-alpha DDR4 memory technology for automotive, industrial, medical, aerospace, and defense customers 2

.

Japan has treated the Hiroshima deal as part of a larger industrial strategy, with Prime Minister Sanae Takaichi unveiling a long-term roadmap targeting ¥101.6 trillion in combined public and private investment in semiconductors and AI through 2041 1

1

. Tokyo has committed tens of billions of dollars to chipmakers since 2021 in an effort to rebuild a domestic industry that once led the world in memory production before ceding ground to South Korea 1

. Market analysts believe Micron is well positioned to benefit from robust AI-related demand, particularly for advanced memory chips used in next-generation computing, with continued investments by major technology companies in AI infrastructure expected to support revenue and earnings growth over the coming years 5
