CoreWeave Expands Partnership with OpenAI in New $6.5 Billion Deal

Cloud computing firm CoreWeave has signed a new $6.5 billion deal with OpenAI. According to Reuters, the new deal is the latest that OpenAI has signed in recent weeks as it seeks partners to support its datacenter construction to secure computational power. The latest deal expands the CoreWeave-OpenAI partnership, pushing the value of their contracts to $22.4 billion.

Third Deal this Year

This is the third time that the two companies are expanding their partnership this year. In March 2025, CoreWeave partnered with OpenAI in an $11.9 billion deal aimed at providing AI technology and data centers over the next five years. The deal was followed by a $4 million agreement in the month of May 2025.

“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.

CoreWeave listed publicly in March 2025 and generates revenue by leasing out data centers that are packed with NVIDIA chips. The AI cloud computing firm is backed by NVIDIA. At the beginning of this month, CoreWeave’s stock soared after the AI firm revealed that NVIDIA had placed a $6.3 billion order. The cloud computing provider also generates significant revenue from Microsoft, which is a major investor in OpenAI.

In July 2025, CoreWeave announced a $6 billion investment towards establishment of an AI data center in Pennsylvania. The investment is aimed at supporting the equipping of the new, state-of-the-art data center, which is expected to power the most competitive AI use cases. Initially, the facility will utilize 100 megawatts of power. This capacity is expected to expand to 300 megawatts, turning the facility into one of the large-scale data centers in the region.

Pushing the Stargate Project Forward

The partnership between OpenAI and CoreWeave comes soon after the AI startup gave major updates about its AI infrastructural project. On September 23, 2025, the AI startup announced that it will open three new sites under a $300 billion deal with its cloud partner, Oracle. The new sites are part of OpenAI’s Stargate project.

OpenAI also said it will establish two more data centers in partnership with SoftBank, bringing the total Stargate data centers to five. These additions increased the Stargate project’s total planned capacity to nearly 7 gigawatts, with over $400 billion in projected investment over the next three years.

“The combined capacity from these five new sites, along with our flagship site in Abilene, Texas, and ongoing projects with CoreWeave, brings Stargate to nearly 7 gigawatts of planned capacity and over $400 billion in investment over the next three years,” OpenAI said in a blog post.

OpenAI plans to construct the new facilities in Texas, New Mexico, Ohio, and the Midwest, a move that will enhance AI data center locations footprint.

Partnerships with Major AI Firms

OpenAI is working to secure an investment of up to $500 billion for the OpenAI 10 gigawatts data center project. Earlier this week, AI chip maker NVIDIA said it will invest up to $100 billion in the AI startup and supply data-center chips. This deal gives NVIDIA a financial stake in one of its largest clients and highlights the collaboration between the two leading actors in the AI race. NVIDIA also holds a 5% stake in CoreWeave.

Beyond U.S. borders, OpenAI and NVIDIA have announced plans to partner in a U.K. data center investment deal on September 12, 2025. Through this deal, which involves collaborating with Nscale Global Holdings, will see the two tech companies strengthen AI infrastructure in the country.

OpenAI’s partnerships with NVIDIA and CoreWeave reflect the converging interests among leading tech firms engaged in advanced AI technologies. Most importantly, the partnerships raise concerns about the circular financing in the industry and the sustainability of the capital flow.
