Why Are CoreWeave, Nebius, and IREN Stocks Tumbling in Pre-Market Today, Oct. 29?
CoreWeave (CRWV), Nebius (NBIS), and IREN (IREN) stocks fell in premarket trading on October 29, following lower-than-expected capital spending reports from Microsoft (MSFT) and Alphabet (GOOGL). Microsoft reported $45.2B in capex, below the $50.7B estimate, while Alphabet reported $51.36B against a $55.09B forecast. Both companies are major customers for neocloud firms, raising concerns about AI infrastructure spending and data center capacity.
