Neocloud stocks fall as Elon Musk says 200 companies in the sector may collapse

Shares of AI “neocloud” companies fell after Elon Musk warned that more than 200 firms renting computing power could face collapse or consolidation. Nebius and CoreWeave each declined about 4% on Monday, while Iren dropped 3.2%. Musk said debt markets had largely stopped funding companies without substantial revenue beyond AI data centers, raising the prospect that only a small number of neoclouds will survive. He was responding to investor Chamath Palihapitiya, who cautioned that some planned computing capacity could be left unused or earn too little to cover its financing costs in 2027.

The warning lands amid a steep sell-off and concerns that companies are borrowing heavily to buy Nvidia chips and build data centers without assurance of lasting returns. Over the past month, CoreWeave and Nebius shares fell more than 30%, and Iren’s dropped 40%; CoreWeave’s rising credit-default-swap spreads and bond yields added to worries about its financial risk. Nvidia CEO Jensen Huang countered that customer demand for neocloud capacity is exceptionally strong, arguing that limited working capital - not a lack of buyers - is the constraint. Nebius and Iren executives likewise said customers are seeking more capacity than they can provide, including for 2027 and 2028. Their assurances contrast with market fears that debt costs, oversupply, and weak returns could force a shakeout.
