NextFin news, CoreWeave, a U.S.-based AI cloud infrastructure provider, announced on Thursday, September 25, 2025, that it has signed a new contract worth up to $6.5 billion with OpenAI to expand its supply of data center capacity. This latest agreement increases the total value of their partnership to $22.4 billion, marking a significant expansion in AI infrastructure support for OpenAI's operations.
The deal, signed in the United States, aims to provide OpenAI with the advanced computing resources necessary to train and deploy next-generation high-performance AI models. CoreWeave's infrastructure includes data centers equipped with cutting-edge AI chips, positioning the company as a key partner in OpenAI's strategy to diversify and scale its cloud computing capabilities.
This $6.5 billion addition follows earlier agreements in March 2025, when OpenAI initially signed a deal with CoreWeave valued at up to $11.9 billion, and a subsequent $4 billion expansion in May 2025. Together, these contracts reflect OpenAI's efforts to reduce reliance on Microsoft Azure by broadening its cloud infrastructure partnerships.
CoreWeave's CEO highlighted that the expanded contract will support OpenAI's ambitious plans to increase its data center capacity, which is part of a broader industry trend toward massive investments in AI computing power. OpenAI's vice president responsible for infrastructure and industrial computing acknowledged CoreWeave as a critical infrastructure partner in the company's AI development roadmap.
The announcement coincides with OpenAI's launch of new data center sites under its Stargate project, including partnerships with Oracle and SoftBank, aiming for nearly 7 gigawatts of planned data capacity and projected investments exceeding $400 billion over the next three years. CoreWeave's expanded contract is integral to this large-scale infrastructure build-out.
Financially, CoreWeave's shares closed at $126.65 on the New York Stock Exchange on the day of the announcement, down 5.1% from the previous trading session. The company went public in March 2025 at $40 per share, with its stock price more than tripling in six months, reflecting investor confidence in its growth prospects tied to AI infrastructure demand.
Industry analysts note that this deal exemplifies the rapid scaling of AI infrastructure investments by leading AI firms like OpenAI, driven by the increasing computational demands of advanced AI models. CoreWeave's role as a 'neo-cloud' provider specializing in AI-optimized data centers is central to meeting these demands.
In summary, on Thursday, September 25, 2025, CoreWeave and OpenAI solidified their expanded partnership through a $6.5 billion contract in the U.S., enhancing OpenAI's AI infrastructure capacity and marking a strategic move to diversify cloud partnerships beyond Microsoft, supporting the future growth of AI technologies.
