AI capex-sensitive stocks fall amid rising OpenAI worries

Shares of AI capex-sensitive firms slid after a Wall Street Journal report said OpenAI missed key user and revenue targets and faces scrutiny over its heavy computing spend. Stocks such as Oracle, CoreWeave and AMD fell in premarket trade (Oracle/CoreWeave ~-3.5%, AMD ~-2.7%), stoking concerns about the sustainability of the AI spending boom and pressuring tech-linked markets. The report — noting OpenAI missed a 1 billion weekly-user goal, missed revenue targets, and may burn through a recent $122 billion funding round within three years — raised questions about partner demand for cloud compute, slowing capex commitments and the timing of a potential OpenAI IPO. The news weighed on sentiment for the US Tech 100 and other AI/cloud-related names.
