TMTPOST -- Shares of CoreWeave (CRWV) surged more than 50% last week after the AI cloud provider reported a remarkable quarterly revenue jump and revealed that Nvidia (NVDA) owns a larger stake in the company than previously expected. CoreWeave, which went public in late March, announced on Wednesday that its first-quarter revenue soared over 400% year-over-year. A regulatory filing on Thursday disclosed that Nvidia, a key partner, now holds a 7% stake in CoreWeave—up from about 5% before the IPO. Additionally, the company revealed last week a new four-year agreement with OpenAI, the creator of ChatGPT, valued at up to $4 billion. This deal builds on a nearly $12 billion commitment CoreWeave announced in March, highlighting its growing role in powering AI infrastructure.
