CoreWeave Shares and Credit Markets Signal Growing Doubt

CoreWeave is facing a sharp deterioration in market sentiment, with its stock down 29% in October alone — a decline that would be alarming for any company, but carries particular weight for a firm that went public amid enormous expectations tied to the artificial intelligence infrastructure boom.
