The investment comes as artificial intelligence fuels unprecedented demand for high-bandwidth memory (HBM) and DRAM chips. Micron plans to significantly expand its US manufacturing footprint to support hyperscale data centres, cloud providers and AI infrastructure, positioning itself to benefit from the long-term AI boom.

Alongside its manufacturing expansion, Micron has committed an additional $3 billion to strengthen the US semiconductor supply chain. About $500 million will support GlobalWafers' silicon wafer facility in Texas under a long-term supply agreement, helping secure a critical component used in chip production.

Micron shares surged more than 6% after the investment plan was unveiled, reflecting optimism about the company's long-term growth prospects. The announcement also lifted sentiment across the broader semiconductor sector, with investors viewing the move as a strong commitment to capitalise on the AI-driven technology cycle.

The investment will support Micron's expansion projects across New York, Idaho and Virginia, reinforcing efforts to bring more semiconductor production back to the United States. The company expects the initiative to generate over 90,000 jobs, including construction, manufacturing and supply-chain roles, providing a significant boost to the domestic economy.

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

Micron's $250 billion investment plan marks one of the largest commitments to US semiconductor manufacturing in recent years. By expanding production capacity and strengthening its supply chain, the company is positioning itself to capture growing AI demand while supporting America's efforts to build a more resilient domestic chip industry.
