Neocloud stocks including CoreWeave, Nebius and Iren fell in early trading on October 26, 2026, before rebounding later in the day. The moves followed Elon Musk’s warning that many companies renting AI computing capacity could fail or consolidate.

Key Takeaways

  • CoreWeave and Nebius shares were down more than 30% over the preceding month, while Iren had fallen 40%.
  • Musk said debt financing had become harder to obtain for companies without substantial revenue outside AI data centers.
  • Nvidia and executives at Nebius and Iren maintained that demand for AI computing capacity remains strong.

Neocloud stocks face financing concerns

The early declines added to a difficult month for the three companies, which rent computing power to customers. Their later rebound did not establish whether Musk’s comments caused the initial moves.

Investors have been concerned about borrowing used to buy Nvidia chips and build data centers, as well as whether the infrastructure will generate sufficient returns. Earlier in October, the spread on CoreWeave’s five-year credit default swaps reached levels generally viewed as signs of distress, while yields on its bonds also climbed.

Musk warns of failures and consolidation

In a post on X on October 25, Musk said debt markets had almost entirely shut off access to money for companies without substantial revenue independent of AI data centers. He predicted that many of more than 200 neocloud companies would fail or consolidate, while some would survive.

Musk’s SpaceX operates data centers and sells computing capacity, making it a competitor to neocloud providers. His prediction is not a confirmed count of companies facing failure.

Executives point to continued demand

Nvidia CEO Jensen Huang said demand for neocloud services was “off the charts,” while describing a scarcity of capital to fund growth. Nvidia is an investor in several neocloud companies.

Nebius Chief Revenue Officer Marc Boroditsky said his company did not carry the same kind of debt as CoreWeave and maintained that Nebius could sell out its planned 2027 capacity. Iren Co-CEO Daniel Roberts also said customer demand remained strong.
