Jim Cramer has asserted that Micron Technology (MU) is planning to build new manufacturing facilities, signaling a major capex push in the memory semiconductor sector. The move could reshape global DRAM and NAND supply dynamics amid rising demand and competitive pressures.
- Micron (MU) is planning to build new semiconductor plants, per Jim Cramer’s statement
- Expected capacity expansion could increase global DRAM and NAND output by over 20% within three years
- MU’s capex surge may improve supply stability for AI and data center demand
- Related stocks NVDA, AMD, and INTC could benefit from reduced memory input costs
- TSM may face indirect competition as MU expands in-house manufacturing
- MU stock rose 3.4% in pre-market trading following the announcement
Jim Cramer has publicly stated that Micron Technology (MU) is set to construct new semiconductor fabrication plants, marking a significant expansion of its manufacturing footprint. The development comes amid growing demand for memory chips used in data centers, AI systems, and consumer electronics. While details on location and timing remain unconfirmed, Cramer’s comment underscores expectations of a substantial capital expenditure increase by the company. Micron’s planned plant expansion could add several gigawatt-hours of annual DRAM and NAND production capacity, potentially exceeding 20% growth in its global output over the next three years. This would position MU to better compete with industry leaders like Samsung, SK Hynix, and emerging players in the U.S. and Asia. The move also aligns with broader U.S. industrial policy goals to strengthen domestic semiconductor production, particularly in light of recent supply chain vulnerabilities. The anticipated build-out may impact related equities such as NVIDIA (NVDA), AMD (AMD), and Intel (INTC), which rely on stable memory supply. Increased availability of DRAM and NAND could ease supply constraints, potentially reducing input costs for these companies. Meanwhile, Taiwan Semiconductor Manufacturing (TSM) may see indirect pressure on its foundry contract volume if Micron ramps up more in-house capacity for memory-intensive AI chips. Market reactions were immediate, with MU stock rising 3.4% in pre-market trading on January 12, 2026, while NVDA and AMD also posted modest gains. Analysts note that investor sentiment remains sensitive to capex signals in semiconductors, particularly given tightening global trade dynamics and subsidy-driven incentives for domestic production. The announcement has heightened speculation about a broader wave of infrastructure investment in the sector.
