CoreWeave Lands $6B AI Deal With Jane Street, Secures $1B Equity Investment

CoreWeave has secured a $6 billion commitment from trading firm Jane Street to use its artificial intelligence cloud platform, alongside a $1 billion equity investment, marking one of the largest customer-backed deals in the rapidly expanding market for AI infrastructure.

The agreement expands an existing relationship between the two companies and will give Jane Street access to next-generation compute capacity across multiple facilities operated by CoreWeave. The deployment includes systems built on Nvidia’s upcoming Vera Rubin architecture, as well as integrated software and services designed to support large-scale model training and deployment.

Jane Street will also purchase $1 billion of CoreWeave’s Class A shares at $109 apiece, underscoring a tighter alignment between the infrastructure provider and one of its largest customers. The combined commitment reflects the trading firm’s increasing reliance on machine learning to process vast datasets and refine trading strategies.

The deal highlights how AI infrastructure providers are increasingly securing long-term revenue visibility through large enterprise commitments, particularly from firms outside traditional technology sectors. Financial trading firms like Jane Street have become heavy users of advanced compute, applying deep learning models to optimize pricing, liquidity provision and risk management across global markets.

For CoreWeave, the agreement adds to a growing roster of high-profile customers and reinforces its positioning as a specialized cloud provider focused on GPU-intensive workloads. The company has been rapidly scaling capacity to meet demand from AI developers, enterprises and research organizations, often differentiating itself through customized infrastructure offerings such as dedicated networking and tailored storage configurations.

Jane Street said the expanded access to CoreWeave’s platform will support its ongoing efforts to train increasingly complex models and deploy them at scale, as competition intensifies in quantitative trading and data-driven market making.

The announcement comes amid a surge in capital flowing into AI infrastructure, with companies racing to build out data centers and secure power, hardware and financing to support next-generation workloads. CoreWeave has been at the center of that buildout, leveraging both debt and equity markets alongside customer commitments to fund its expansion.
