CoreWeave and other neocloud stocks drop after Microsoft capex comes in below expectations
CoreWeave and Nebius shares dropped 5% in extended trading after Microsoft's capex of $45.2B missed estimates, raising concerns about neocloud infrastructure demand. Microsoft's Azure revenue grew 48%, but lower capex suggests slower data center expansion. Alphabet also missed capex expectations. Analysts predict 80% of neocloud companies may fail by 2030. CoreWeave had gained 18% before the drop, closing at $63.93.
