Micron shares jump 2.3% after Nvidia reports record sales driven by AI infrastructure demand

Micron (NASDAQ:MU) stock rose 2.3% in the afternoon session following Nvidia's announcement of record sales and income, which the CEO described as driven by 'parabolic' demand for AI infrastructure. Shares subsequently cooled to $758.44, up 4% from the previous close.

Strong semiconductor demand reflects a massive buildout of data centers requiring high-performance chips, particularly High Bandwidth Memory (HBM) components. Analysts have declared a 'semiconductor supercycle'—a prolonged period of above-average growth—as companies worldwide develop AI capabilities.

Micron is up 140% since the beginning of the year and trades close to its 52-week high of $803.63 from May 2026. The semiconductor sector's long-dated cash flows (valued primarily in 2027–2030 AI capex) are sensitive to discount rate changes; when Brent crude dropped 5.21% during the session, expected inflation fell and the rate compression produced outsized stock moves.
