## Key points

- Neocloud firms’ shares have fallen sharply amid concerns about debt.
- CoreWeave has $35.1bn in debt.
- Their prospects depend heavily on continued AI investment.

## Summary

Neocloud companies such as CoreWeave and Nebius rent computing power to major AI developers, but growing concerns about their debt and exposure to customer spending have made them a focus of debate over whether the AI boom is sustainable. Their recent share-price falls have sharpened questions about the financial risks behind the rapid expansion of AI infrastructure.

These firms often borrow against long-term customer contracts and the costly chips they buy upfront; CoreWeave has accumulated $35.1bn in debt. Its shares and those of Nebius, IREN and Applied Digital have each fallen by about a quarter or more in the past month, while lenders are seeking higher returns. Many companies began in crypto mining, and analysts warn their fortunes depend on major customers continuing to spend: Gartner predicts 80% of neocloud firms will cease independent operations by 2030.
