Summary: Jane Street has entered into a $6 billion AI cloud agreement with CoreWeave, taking a $1 billion equity stake at $109 per share, positioning the quantitative trading firm among CoreWeave’s top five shareholders. This deal grants Jane Street access to NVIDIA’s next-gen Vera Rubin compute and complements CoreWeave’s expanding contract portfolio, including agreements with Meta ($35B), OpenAI ($12B), and NVIDIA ($6.3B in commitments).
Jane Street, the quantitative trading firm earning $20.5 billion in net trading revenue last year, secured a $6 billion AI cloud deal with CoreWeave while also investing $1 billion in equity at $109 per share, indicative of shifting finance and AI infrastructure markets.
Per the agreement, CoreWeave will offer Jane Street access to next-gen compute in multiple data centers, utilizing NVIDIA’s upcoming Vera Rubin architecture. Jane Street’s $1 billion equity investment at $109 per share makes it a top five CoreWeave shareholder, with stocks now valued at a 176% premium over its IPO price 13 months ago.
Why Jane Street required $6 billion in cloud capabilities
Uncharacteristic for a CoreWeave client, Jane Street, established in 2000 with international offices, runs a research-focused trading unit utilizing tens of thousands of advanced GPUs. Their engineers develop neural network models driving trading strategies and real-time processing vast market data volumes.
The company described the deal in AI research lab terms: “training expansive, intricate models on massive noisy data volumes for efficient market-making.” Max Hjelm from CoreWeave remarked: “Jane Street resembles a frontier lab.”
The comparison holds. Jane Street’s 2024 net income hit $13 billion—sufficient to train multiple frontier language models. By 2025’s third quarter, the firm’s revenue surpassed $24 billion, with a single quarter (Q2 2025) yielding $10.1 billion net trading revenue, indicating capacity for frontier scale compute consumption.
CoreWeave’s contract expansion
For CoreWeave, the deal continues its transformation from niche GPU cloud provider to major AI infrastructure player. Publicly listed on Nasdaq in March 2025 at $40 per share, raising $1.5 billion at a $23 billion valuation, subsequent contracts have dwarfed its IPO market cap.
Meta’s deal alone is valued at $35 billion through 2032, expanded from an initial commitment. OpenAI has committed about $12 billion spanning five years. NVIDIA invested $2 billion in CoreWeave in January 2026 and separately agreed to purchase $6.3 billion in remaining compute capacity until April 2032, essentially backing CoreWeave’s growth with demand assurance. Jane Street’s $6 billion commitment adds another major client to its lineup including Anthropic, Google, and Microsoft.
The concentration of AI expenditures among a few cloud providers is reshaping the infrastructure landscape. CoreWeave’s offering is specialization: building solely for AI workloads, delivering dedicated connectivity, custom storage, and responsive technical support unmatched by general-purpose cloud providers for demanding clients.
The impact of Vera Rubin
The deal includes access to NVIDIA’s Vera Rubin technology, the next-gen GPU platform claimed to offer up to ten times reduced cost per token versus the current Blackwell architecture. CoreWeave is one of the first cloud entities to offer Vera Rubin systems, with delivery in Q2 2026.
For Jane Street, the attraction is evident. Quantitative trading models are becoming more intricate and computationally demanding, and firms with the ability to train and refine them swiftly gain a competitive edge. Access to novel technology in advance of competitors is crucial; in a sector where milliseconds count, it means the difference between trade opportunities gained or missed.
The equity investment emphasizes this point. With a $1 billion stake in CoreWeave, Jane Street isn’t merely acquiring cloud capacity; it’s aligning its financial interests with the infrastructure essential to its operations. Should CoreWeave thrive, Jane Street benefits as both client and shareholder.
Implications
This deal underscores the dissolving boundaries between AI firms and their clientele. Jane Street, a trading firm, operates its GPU clusters, employs machine learning experts, and now funds AI infrastructure providers directly. This trend is visible across finance: hedge funds, high-frequency trading firms, and quantitative asset managers are all committing billions to compute infrastructure fueling their models.
This has broader implications beyond finance. CoreWeave’s contracts, totaling tens of billions, assume AI compute demand continues growing, justifying substantial capital investments.
