Nvidia is a major customer of CoreWeave and a key investor. CoreWeave stock rose earlier in May after Nvidia disclosed a stake in the stock, at 24.2 million shares that are now worth more than $2.5 billion, or significantly more than Nvidia paid for them when CoreWeave went public in late March 2025.

Nvidia’s earnings have become some of the most closely watched numbers on Wall Street. The company makes up about 6.5% of the Nasdaq 100 and 5.5% of the S&P 500, so a good quarter can send the Nasdaq index soaring. A marginal or poor one can send it tumbling.
