Micron, Nvidia and AI chip stocks fall as report on OpenAI’s revenue causes ‘undue concern’

A report suggesting OpenAI's annualized revenue fell short of expectations rippled through semiconductor shares, with Micron, Nvidia and other AI-linked chip names coming under pressure. The reaction reflects how tightly portions of the chip sector's valuation are now tied to perceptions of AI demand.

Analysts pushed back, describing the market's response as "undue concern." In their view, the reported figure reflects differences in how annualized revenue is calculated and disclosed rather than any deterioration in underlying demand for AI computing. Annualized revenue, which extrapolates a shorter period into a full-year pace, can vary widely depending on the snapshot used and what is included.

For investors, the episode illustrates how sensitive AI-related equities have become to headline data points about a small number of private companies. What to watch: whether upcoming earnings from chipmakers and cloud providers confirm continued capital spending on AI infrastructure, and whether subsequent reporting on OpenAI's revenue clarifies the measurement question. Until then, single data points may keep driving outsized moves.
