Shares of major neocloud companies fell sharply on Monday after Elon Musk, CEO of SpaceX and Tesla, warned that more than 200 firms in the sector could face collapse. Musk’s remarks, posted on X on Sunday, cited a sharp decline in debt market access for companies reliant on AI data centers for revenue.
Nebius, CoreWeave, and Iren saw premarket declines of over 4%, adding to pressure on a sector already grappling with investor concerns over debt-fueled expansion and the long-term viability of AI infrastructure investments. Musk stated that debt markets have "almost entirely shut off access to money" for companies without substantial revenue outside AI data centers, predicting a wave of "guppy-level death and consolidation" in the industry. He added that only a small number of neoclouds would survive the shakeout.
Musk’s SpaceX operates its own data centers, competing directly with neocloud providers by selling computing capacity. In a separate X reply on Friday, he also warned of "stranded compute"—computing power ready for deployment but unused due to incomplete data center infrastructure. This refers to partially built facilities unable to activate their compute resources.
Venture capitalist Chamath Palihapitiya previously described neoclouds as "disorganized and poorly capitalized" in an X post, to which Musk replied that SpaceX has no plans to acquire struggling neoclouds. "SpaceX is not buying any neoclouds. Pointless," he wrote. CoreWeave’s stock has dropped approximately 37% over the past month, while Nebius’ has fallen 30% in the same period.
Nvidia CEO Jensen Huang has countered the pessimism, asserting that demand for AI cloud infrastructure remains "off the charts." Nvidia is a major investor in several neocloud firms, including CoreWeave, Nebius, Iren, and Lambda. The divergence in outlook highlights broader uncertainty over whether the AI infrastructure buildout will generate sufficient returns to sustain current levels of investment.
