Why Nvidia, Oracle and CoreWeave fell Oct. 8

Nvidia, Oracle and CoreWeave fell Oct. 8 after OpenAI revenue details came out, CNBC reported. The drop came after the S&P 500 — the index tracking 500 big U.S. companies — hit a record in early October and Nvidia neared $6 trillion in value, per Bloomberg. For index-fund savers, returns rest heavily on one customer turning AI spending into sales.
