Global trading firm Jane Street has agreed to spend around $6 billion on AI cloud services from CoreWeave, while also investing $1 billion in the company’s equity, deepening an existing partnership between the two.
The agreement will give Jane Street access to advanced computing infrastructure across CoreWeave’s data centres, including systems powered by NVIDIA’s latest Vera Rubin technology. The setup is designed to support large-scale machine learning workloads used in trading and research.
As part of the deal, Jane Street purchased CoreWeave Class A shares at $109 each, signalling a long-term commitment to expanding its use of AI across its operations.
“We are deeply committed to investing in cutting-edge technologies that support our research in global financial markets, training large, complex models on massive volumes of noisy data, refining them continuously, and deploying at a scale to help make markets more efficient,” said Jane Street. “Access to CoreWeave’s leading AI cloud platform enables our researchers to move at the pace our competitive business demands.”
The partnership reflects growing demand for high-performance computing in finance, where firms are increasingly relying on complex AI models trained on massive datasets to improve trading strategies and market efficiency.
CoreWeave said its cloud platform was chosen for its ability to combine powerful hardware with integrated software tools, helping clients run AI systems more efficiently at scale.
The company also provides customised infrastructure, including dedicated connectivity and storage, tailored to Jane Street’s needs.
Founded in 2017, CoreWeave focuses on AI-first cloud infrastructure and went public on Nasdaq in 2025.
“Jane Street operates like a frontier lab, continually breaking new ground in deep learning and pushing the scale and complexity of their models,” said Max Hjelm, Senior Vice President of Revenue at CoreWeave. “CoreWeave was built for this purpose, and we’re excited to expand our collaboration with Jane Street.”
