Nebius Group N.V.Altman's warning on unsustainable AI compute spending and Nebius's reliance on three customers for 59% of revenue raise doubts about its $37.5B backlog.
OpenAI CEO Sam Altman warned of "unsustainable silliness" in AI compute spending, saying some new neoclouds lack the revenue or buyers to support their buildout plans, and traders are reassessing publicly traded AI compute stocks. The names in focus include CoreWeave, Nebius Group, IREN, Hut 8, Bitdeer Technologies, and Cipher Mining. CoreWeave reports a revenue backlog of approximately $104 billion, Nebius has $37.5 billion in remaining performance obligations, Hut 8 has $26.6 billion in base-term contract value, and Bitdeer signed a $4.70 billion lease with Volta. However, risks include high debt, such as Cipher's $6 billion debt against $562 million equity, and customer concentration, with Nebius relying on three customers for 59% of revenue. Altman also noted that if compute costs fall, some may have made "dumb financial decisions," a common feature of booms.
