Neocloud Volatility Continues as Debt Concerns Grow 

Nebius (NBIS), CoreWeave (CRWV), and IREN (IREN) each had a volatile session of trading following Elon Musk’s Sunday post on X. Musk said debt markets have “almost entirely shut off access to money” for companies without substantial revenue outside AI data centers and predicted that more than 200 neoclouds face “guppy-level death and consolidation,” adding that “some will make it through, but not many.” The declines compounded pressure the group was already facing amid concerns over debt-funded expansion and whether the AI buildout will generate adequate returns. Nebius ended the day down over 3%, while Iren and CoreWeave ended the day positive on the session.
