AI Infrastructure Stocks Rattled by Neocloud Sector Fears

A wave of investor anxiety is sweeping through the artificial intelligence infrastructure sector, with companies like CoreWeave at the center of growing doubts about the durability of the so-called neocloud business model. The sell-off and sentiment shift are rippling outward, unsettling a wider swath of the AI industry that had until recently commanded robust valuations and confident outlooks.

Neocloud companies — specialized cloud providers that lease high-powered GPU clusters primarily to AI developers — emerged as darlings of the post-ChatGPT investment boom. Their pitch rested on surging demand for compute capacity that traditional hyperscalers like Amazon Web Services and Microsoft Azure could not fulfill fast enough.
