Jane Street is committing $6 billion to CoreWeave's AI cloud and buying $1 billion in stock

Jane Street has committed about $6 billion to use CoreWeave's AI cloud platform and made a separate $1 billion equity investment in the company, bringing its total commitment to $7 billion, the companies said April 15.

Under the cloud agreement, CoreWeave will give Jane Street access to compute across multiple data center facilities, including Nvidia $NVDA's Vera Rubin technology, along with the software and services needed to deploy and scale its AI operations. CoreWeave said the arrangement includes dedicated connectivity, custom storage configurations, and technical support tailored to Jane Street's research needs.

According to Reuters, the $109-per-share price Jane Street paid for its CoreWeave equity stake represented a 7% discount to where the stock last closed. Reuters reported that with the new purchase folded in, Jane Street holds roughly $1.44 billion worth of CoreWeave stock in total, a position large enough to rank it among the company's five biggest shareholders.

"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," Jane Street said in a statement. "Access to CoreWeave's leading AI cloud platform enables our researchers to move at the pace our competitive business demands."

Max Hjelm, Senior Vice President of Revenue at CoreWeave, said in a statement that "Jane Street operates like a frontier lab, continually breaking new ground in deep learning and pushing the scale and complexity of their models."

The deal is the third major agreement CoreWeave has announced this month. Earlier, CoreWeave signed a $21 billion agreement with Meta $META to supply AI cloud capacity through 2032, expanding a prior contract valued at about $14 billion. A day later, CoreWeave reached a multi-year agreement with Anthropic to provide compute supporting the development and deployment of Claude AI models, though financial terms of that deal were not disclosed.

CoreWeave, which completed its public listing on Nasdaq $NDAQ in March 2025, has been working to broaden its customer base and expand its software offerings beyond access to Nvidia processors. The company had been heavily dependent on Microsoft $MSFT, which accounted for about 70% of its revenue last year, according to Bloomberg. CoreWeave shares have nearly doubled from their starting point this year, gaining roughly 64% since January.

Jane Street, founded in 2000, is a technology-driven trading firm with more than 3,500 employees across offices in New York, London, Hong Kong, Singapore, and Amsterdam. The firm uses large-scale computing to fuel trading algorithms. Its revenue in the first nine months of 2025 surpassed $24 billion, according to Bloomberg, well above its previous annual record of $20.5 billion set in 2024.
