AI fatigue is gripping the market and driving chip stocks toward their worst stretch in 16 months

The market's patience with artificial intelligence spending appears to be thinning. According to Dow Jones reporting, anticipation is building for Anthropic's investor day while Wall Street grows less patient with heavy AI outlays — a shift in sentiment that has chip stocks heading toward their worst stretch in 16 months.

The dynamic reflects a maturing phase of the AI trade. Earlier, announcements of large capital expenditures were often rewarded as evidence of ambition; now investors appear to be weighing those costs against the timing and visibility of returns. When spending is scrutinized rather than applauded, semiconductor shares — the most direct beneficiaries of AI infrastructure buildouts — tend to feel the adjustment first, since their valuations embed expectations of continued, aggressive demand.

What to watch: whether Anthropic's investor day offers concrete detail on revenue trajectories and cost discipline, and whether other major AI spenders face similar questions in coming earnings cycles. For market observers, the key question is whether this is a pause in enthusiasm or a broader reassessment of how AI investment is valued. Neither outcome is predetermined — the data ahead will shape the answer.
