CoreWeave shares surge 19.34% after hours as Nvidia invests $2 billion, nearly doubling its stake in the AI cloud provider.

CoreWeave surged 19.34% in after-hours trading following news that Nvidia invested an additional $2 billion in the company, nearly doubling its stake to make it the second-largest shareholder. The investment, described as a vote of confidence, aims to expand CoreWeave’s AI infrastructure capacity and data centers, aligning with the company’s role as a key enabler of AI growth. While a new brand campaign featuring Chance the Rapper and a class-action lawsuit over data center delays were also reported, the latter two events were either neutral/long-term focused or contradicted the upward price movement. The Nvidia investment directly fueled the sharp after-hours rally, signaling strategic and financial support for CoreWeave’s expansion.
