Jane Street Commits $6 Billion to CoreWeave and Acquires $1 Billion Stake

Jane Street signed a $6 billion AI cloud deal with CoreWeave, and also acquired $1 billion worth of shares at $109 per share. Through this deal, Jane Street became one of CoreWeave's top 5 shareholders.

The agreement includes access to NVIDIA's next-generation Vera Rubin compute. Jane Street already operates tens of thousands of high-performance GPUs on its own infrastructure, using machine learning models that process massive, noisy market data in real time for its trading strategies.

According to the article, Jane Street's net trading revenue last year was $20.5 billion, and its 2024 net income was $13 billion. Also, revenue through the third quarter of 2025 already exceeded $24 billion, and Q2 2025 net trading revenue alone reached $10.1 billion.

For CoreWeave, its customer portfolio has grown larger. The company listed on the Nasdaq at $40 in March 2025, raising $1.5 billion, with a market cap of about $23 billion at the time of listing.

Since then, deals have piled up quickly.

• Meta: $35 billion scale through 2032
• OpenAI: approximately $12 billion over 5 years
• NVIDIA: a commitment to purchase $6.3 billion worth of unsold compute capacity
• Jane Street: a $6 billion deal plus a $1 billion equity investment

Unlike general-purpose cloud, CoreWeave positions itself around infrastructure specialized for AI workloads. It's attracting large customers with dedicated connectivity, custom storage configurations, and fast technical support, and its Vera Rubin systems are scheduled to be deployed starting Q2 2026.

The core message is clear: the boundary between finance and AI infrastructure is blurring, and major quant hedge funds have entered a phase of buying cloud capacity not as a mere expense but as a strategic asset. If AI compute demand keeps surging, CoreWeave's long-term contracts become a growth engine; if demand slows, those same contracts could turn into a burden.
