Michael Intrator, co-founder and chief executive officer of CoreWeave Inc., during an interview on the floor of the New York Stock Exchange (NYSE) in New York, US, on Monday, Sept. 22, 2025.
CoreWeave on Thursday announced a $6.5 billion deal with OpenAI, expanding its current agreement with the artificial intelligence startup behind ChatGPT.
The new agreement brings the AI cloud infrastructure provider's total contracts with OpenAI to $22.4 billion.
"This milestone affirms the trust that world-leading innovators have in CoreWeave's ability to power the most demanding inference and training workloads at an unmatched pace," CoreWeave CEO Michael Intrator said in a statement.
In March, CoreWeave announced an $11.9-billion agreement with OpenAI to provide AI datacenters and technology over five years. Intrator told CNBC in May that the companies expanded the agreement by $4 billion.
CoreWeave, which went public in March, makes money by renting out and building data centers packed with numerous Nvidia graphics processing units. The company is backed by Nvidia and makes a significant chunk of its revenue from Microsoft , which is a key investor in OpenAI.
At the time of its prospectus, CoreWeave said it operated 32 datacenters powered by more than 250,000 Nvidia GPUs. Its datacenter plans span the U.S. and parts of Europe, including the United Kingdom, Spain and Sweden.
Some of CoreWeave latest projects include a $6-billion deal for an initial 100 megawatt datacenter in Lancaster, Pennsylvania and a multibillion-dollar commitment to building up AI datacenter capacity in the U.K.
Companies across the AI sector are racing to meet booming demand for computing capacity. That's ramped up the pressure on companies such as Open Ai and Nvidia.
OpenAI CEO Sam Altman told CNBC's Jon Fortt earlier this month that the compute constraints faced by the AI company and industry "have been terrible."
"We're so limited right now in the services we can offer," he added.
Earlier this week, Nvidia announced a $100-billion investment in OpenAI to support its datacenter buildout using the chipmaker's AI processors.
