Musk Warns Over 200 Neocloud Firms Face Collapse as Stocks Swing Sharply

Elon Musk said more than 200 neocloud companies could fail, a warning that sent shares of several publicly traded providers swinging sharply. Nebius, Iren and CoreWeave all dropped in early trading on Monday, then recovered later in the session.

Musk, who is CEO of SpaceX and Tesla, made the comments in a post on X on Sunday. "As of the past few weeks, debt markets have almost entirely shut off access to money for any company that doesn't have substantial revenue independent of AI data centers," he wrote. He added that the 200-plus neoclouds "are going to see guppy-level death and consolidation. Some will make it through, but not many."

The remarks carry a competitive angle. SpaceX runs its own data centers and sells computing capacity, which puts it in direct competition with neoclouds that also rent out compute.

Musk was responding to a post by Chamath Palihapitiya, founder of Social Capital, who gave his view of the data center buildout. Palihapitiya suggested there will be more partially stranded compute, and more compute sitting in inventory, in 2027 than is currently forecast. That capacity, he said, will be "bought and paid for but effectively underearning (below total cost of capital) or collecting dust." He called 2027 a turbulent year that will clear out bad bets and bring consolidation for some companies.

The sector has already had a rough month. CoreWeave and Nebius shares have fallen more than 30%, while Iren has dropped 40%. The sell-off began earlier in October after the spread on CoreWeave's five-year credit default swaps reached levels generally seen as a sign of distress, and yields on its bonds also rose. Investors have grown nervous about companies borrowing heavily to buy costly Nvidia chips, build data centers and rent out computing power.

Nvidia, which has invested in several neoclouds, tried to steady the sector last week at its GTC event in Berlin. Chief executive Jensen Huang told CNBC that demand for neoclouds is "off the charts." He said the missing piece is working capital, noting that "there's a scarcity of capital" because demand for AI spans so many sectors. "The demand of the capital is much greater than the availability of the capital. That's going to get solved," Huang said.

Executives at the affected companies also defended their positions. Marc Boroditsky, chief revenue officer at Nebius, separated his company from worries around CoreWeave, telling CNBC, "we're not carrying the kind of debt that they are." He said that if Nebius brought its 2027 capacity online, it would sell out, and that "the same type of dynamic" could apply in 2028.

Iren Co-CEO Daniel Roberts said customer demand has not changed. "We understand the increased focus from investors, but when we're talking from customers, nothing has changed. The demand is still there," he told CNBC last week. He said conversations with customers for next year cover multiples of all the capacity the company can bring online, and that 2028 has begun to come into focus in the past month or so.
