In short: Jane Street has signed a $6 billion AI cloud agreement with CoreWeave and taken a $1 billion equity stake at $109 per share, making the quantitative trading firm one of CoreWeave’s five largest shareholders. The deal provides Jane Street with access to NVIDIA’s next-generation Vera Rubin compute and adds to CoreWeave’s growing contract book, which includes Meta ($35B), OpenAI ($12B), and NVIDIA ($6.3B in capacity commitments).
Jane Street, the quantitative trading firm that generated $20.5 billion in net trading revenue last year, has signed a $6 billion AI cloud agreement with CoreWeave and taken a $1 billion equity stake in the company, a deal that says as much about the future of finance as it does about the AI infrastructure market.
Under the agreement, CoreWeave will provide Jane Street with access to next-generation compute across multiple data centre facilities, including systems built on NVIDIA’s forthcoming Vera Rubin architecture. Jane Street’s $1 billion equity investment, at $109 per share, makes it one of CoreWeave’s five largest shareholders and values the cloud provider’s stock at a 176% premium to its IPO price just thirteen months ago.
Why a trading firm needs $6 billion in cloud compute
Jane Street is not a typical CoreWeave customer. The firm, founded in 2000 with offices in New York, London, Hong Kong, Singapore, and Amsterdam, runs a research-driven trading operation that already deploys tens of thousands of high-end GPUs across its own computing infrastructure. Its engineers build neural network models that power trading strategies across global financial markets, processing massive volumes of noisy market data in real time.

The firm’s statement framed the deal in language usually reserved for AI research labs: “training large, complex models on massive volumes of noisy data, refining them continuously, and deploying at a scale to help make markets more efficient.” Max Hjelm, CoreWeave’s senior vice president of revenue, was more direct: “Jane Street operates like a frontier lab.”
That comparison is not hyperbole. Jane Street’s 2024 net income was $13 billion, roughly what it costs to train a frontier language model several times over. Through the first three quarters of 2025, the firm’s revenue had already exceeded $24 billion, with a single quarter, Q2 2025, producing $10.1 billion in net trading revenue. This is a company with both the appetite and the capital to consume compute at frontier scale.
CoreWeave’s contract machine
For CoreWeave, the deal extends a pattern that has transformed it from a niche GPU cloud provider into one of the most consequential infrastructure companies in AI. The company went public on Nasdaq in March 2025 at $40 per share, raising $1.5 billion at a valuation of roughly $23 billion. Since then, it has signed contracts that dwarf its own market capitalisation at IPO.
Meta’s deal alone is worth $35 billion through 2032, expanded from an initial commitment in an agreement announced earlier this month. OpenAI has committed approximately $12 billion over five years. NVIDIA itself invested $2 billion in CoreWeave in January 2026 and separately agreed to purchase $6.3 billion in unsold compute capacity through April 2032, effectively underwriting CoreWeave’s buildout with a demand guarantee. Jane Street’s $6 billion commitment adds another major customer to a roster that also includes Anthropic, Google, and Microsoft.
The concentration of AI spending among a handful of cloud providers is reshaping the infrastructure market. CoreWeave’s pitch is specialisation: rather than competing with AWS or Azure across the full spectrum of cloud services, it builds exclusively for AI workloads, offering dedicated connectivity, custom storage configurations, and the kind of responsive technical support that general-purpose cloud providers struggle to match for demanding customers.
The Vera Rubin factor
The agreement specifies access to NVIDIA’s Vera Rubin technology, the next-generation GPU platform that NVIDIA claims will deliver up to ten times lower cost per token compared to its current Blackwell architecture. CoreWeave is among the first cloud providers to offer Vera Rubin systems, with deployment beginning in Q2 2026.
For Jane Street, the appeal is clear. Quantitative trading models are becoming deeper and more computationally expensive, and the firms that can train and refine them fastest have a direct competitive advantage. Access to next-generation silicon before competitors do is not a nice-to-have; in a business where nanoseconds matter, it is the difference between capturing and missing a trade.
The equity investment reinforces the point. By taking a $1 billion stake in CoreWeave, Jane Street is not just buying cloud capacity; it is aligning its financial interests with the continued buildout of the infrastructure it depends on. If CoreWeave succeeds, Jane Street benefits both as a customer and as a shareholder.
What this signals
The deal is the latest evidence that the boundary between AI companies and their customers is dissolving. Jane Street is a trading firm, but it operates its own GPU clusters, employs machine learning researchers, and now invests directly in AI infrastructure providers. The same pattern is visible across finance: hedge funds, high-frequency trading firms, and quantitative asset managers are all committing billions to the compute infrastructure that powers their models.
This has implications beyond Wall Street. CoreWeave’s ability to sign contracts totalling tens of billions of dollars rests on the assumption that demand for AI compute will continue to grow at rates that justify massive capital expenditure. The company’s customers are, in effect, pre-funding a buildout that will take years to complete. If AI compute demand plateaus or shifts to more efficient architectures faster than expected, the long-term contracts that underpin CoreWeave’s valuation become liabilities rather than assets.
For now, the demand signal is unambiguous. Between Meta, OpenAI, NVIDIA, Jane Street, and a growing list of enterprise customers, CoreWeave has secured commitments that would have been difficult to imagine when it listed thirteen months ago. The company’s stock has nearly tripled since its IPO, and each new contract reinforces the thesis that specialised AI cloud providers can compete with, and in some cases outperform, the hyperscalers on workloads that matter most.
Jane Street’s bet is that the returns on AI-driven trading will justify $6 billion in cloud spending and a $1 billion equity position in the company providing it. Given that the firm made $13 billion in net income last year, the maths is not hard to see. The harder question is whether the broader AI infrastructure boom, in which a handful of companies are committing capital at a pace not seen since the fibre-optic buildout of the late 1990s, will produce returns to match. Jane Street, at least, is trading as though it will.
