Micron Technology's ambitious bet on America's semiconductor industry received a strong endorsement from investors Thursday after the memory chip giant unveiled billions of dollars in new investments designed to strengthen the domestic chip supply chain and meet surging demand fueled by artificial intelligence.
Shares of Micron climbed 7% following the announcement, extending what has already been a remarkable year for the company. It later paired some gains. The stock has surged more than 250% in 2026 as demand for high-bandwidth memory and other AI-related semiconductor products continues to accelerate.
