LIVINGSTON, N.J. – September 25, 2025 – CoreWeave, Inc. (Nasdaq: CRWV), recognized as an AI Hyperscaler™, today revealed a substantial expansion of its agreement with OpenAI, valued at up to $6.5 billion. This new commitment is aimed at powering the training of OpenAI’s most advanced next-generation models, reinforcing CoreWeave’s position as a crucial cloud platform for demanding AI workloads.
This latest agreement elevates the total contract value between CoreWeave and OpenAI to an impressive $22.4 billion. The partnership has seen rapid growth this year, with an initial agreement in March 2025 worth up to $11.9 billion, followed by another expansion in May 2025 for up to $4 billion.
Michael Intrator, Co-Founder, Chairman, and Chief Executive Officer of CoreWeave, expressed pride in the deepening relationship. “We are proud to expand our relationship with OpenAI, a company consistently at the forefront of advancing artificial intelligence,” Intrator stated. He added, “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.”
Peter Hoeschele, VP of Infrastructure and Industrial Compute at OpenAI, echoed this sentiment, noting, “CoreWeave has become an important partner in OpenAI’s broader infrastructure platform. By delivering compute at unmatched speed and scale, they’re helping us advance the frontier of intelligence and ensure AI’s benefits reach everyone.”
The expansion highlights the intense demand for AI infrastructure as companies race to secure data center capacity. CoreWeave’s CEO, Michael Intrator, also emphasized the company’s strategic push for diversification beyond its historical reliance on Microsoft as a key client, stating, “This is the quarter of diversification for us,” as CoreWeave rapidly onboards a broader base of ‘creditworthy’ customers.
This agreement builds on a series of recent milestones for CoreWeave, underscoring its pivotal role in driving AI innovation. This month, the company announced a £1.5 billion commitment to powering UK AI innovation and growth, alongside the launch of CoreWeave Ventures, an initiative dedicated to backing founders and companies shaping the AI ecosystem. Furthermore, CoreWeave has expanded its platform capabilities through the acquisitions of OpenPipe and Weights & Biases.
The broader AI infrastructure landscape is also seeing significant activity. OpenAI is accelerating its “Stargate” infrastructure project, which includes new data center buildouts with Oracle (ORCL) and SoftBank. Nvidia (NVDA), a key supplier and backer of CoreWeave, has also announced its intention to invest up to $100 billion in OpenAI to deploy at least 10 gigawatts of AI data centers with Nvidia systems, representing millions of GPUs for OpenAI’s next-generation AI infrastructure. CoreWeave itself has a $6.3 billion initial order with Nvidia for chip supply.
