Jane Street finalizes a $6 billion agreement for AI cloud services with CoreWeave and commits $1 billion in equity investment.

      In summary, Jane Street has entered into a $6 billion AI cloud agreement with CoreWeave and acquired a $1 billion equity stake at $109 per share, positioning the quantitative trading firm among CoreWeave’s five largest investors. This agreement grants Jane Street access to NVIDIA’s upcoming Vera Rubin computing technology and contributes to CoreWeave’s expanding portfolio of contracts, which also includes deals with Meta ($35B), OpenAI ($12B), and NVIDIA ($6.3B in capacity commitments).

      Jane Street, which generated $20.5 billion in net trading revenue last year, is engaging in this $6 billion agreement with CoreWeave, along with a $1 billion equity investment, highlighting trends in finance as well as the AI infrastructure sector.

      The agreement allows CoreWeave to provide Jane Street with next-generation computing resources across various data center facilities, utilizing systems based on NVIDIA’s soon-to-be-released Vera Rubin architecture. Jane Street’s equity investment at $109 per share positions it as one of CoreWeave’s main stakeholders and assigns a valuation to CoreWeave’s stock at a 176% premium compared to its IPO price from just thirteen months ago.

      Jane Street is not an ordinary customer for CoreWeave. Established in 2000 with locations in New York, London, Hong Kong, Singapore, and Amsterdam, the firm conducts research-driven trading and already utilizes thousands of high-end GPUs within its own computing infrastructure. It develops neural network models that facilitate trading strategies across global markets, processing vast amounts of market data in real time.

      The firm’s announcement described the agreement with terminology typically linked to AI research labs: “training large, complex models on massive volumes of noisy data, continuously refining them, and deploying at scale to enhance market efficiency.” Max Hjelm, CoreWeave’s senior vice president of revenue, stated more plainly: “Jane Street operates like a frontier lab.”

      This comparison is justified. Jane Street’s 2024 net income reached $13 billion, several times the cost associated with training a leading language model. As of the first three quarters of 2025, the firm’s revenue had already surpassed $24 billion, with Q2 2025 alone yielding $10.1 billion in net trading revenue. This demonstrates that the company possesses both the need and the financial resources to utilize compute at a leading scale.

      For CoreWeave, this agreement reinforces its transformation from a niche GPU cloud provider to a significant player in the AI infrastructure market. Following its public listing on Nasdaq in March 2025 at $40 per share, raising $1.5 billion at an approximate valuation of $23 billion, the company has secured contracts that exceed its market valuation at IPO.

      The deal with Meta is valued at $35 billion through 2032, an increase from an initial commitment in a recently announced agreement. OpenAI has pledged about $12 billion over five years. NVIDIA itself invested $2 billion in CoreWeave in January 2026 and separately agreed to acquire $6.3 billion in unsold compute capacity through April 2032, effectively providing a demand guarantee for CoreWeave’s expansion. Jane Street’s $6 billion commitment adds another significant client to CoreWeave’s lineup, which already includes Anthropic, Google, and Microsoft.

      The growing concentration of AI spending among a few cloud providers is reshaping the infrastructure landscape. CoreWeave’s strategy emphasizes specialization: as it does not compete with AWS or Azure across all cloud services, it focuses solely on AI workloads, delivering dedicated connectivity, tailored storage solutions, and responsive technical support that general-purpose cloud providers often struggle to deliver to demanding clients.

      The agreement grants access to NVIDIA’s Vera Rubin platform, the next-gen GPU technology that NVIDIA claims will offer up to ten times lower cost per token compared to its existing Blackwell architecture. CoreWeave will be among the first cloud providers to implement Vera Rubin systems, with deployment commencing in Q2 2026.

      For Jane Street, the allure is evident. Quantitative trading models are increasingly complex and resource-intensive, and firms that can train and refine them the quickest hold a direct competitive edge. Securing next-generation technology before competitors is critical; in a sector where nanoseconds matter, this can determine whether a trade is executed successfully or missed.

      The equity investment emphasizes this point. By investing $1 billion in CoreWeave, Jane Street is not merely purchasing cloud capacity; it is aligning its financial interests with the ongoing development of the infrastructure it relies on. If CoreWeave prospers, Jane Street stands to gain both as a customer and a shareholder.

      This deal reflects the blurring lines between AI companies and their clients. While Jane Street is primarily a trading firm, it operates its own GPU clusters, employs machine learning researchers, and now directly invests in AI infrastructure providers. This trend is observable across the financial sector, as hedge funds, high-frequency trading firms, and quantitative asset managers are pouring billions into the computational infrastructure that drives their models
