Jane Street Commits $7 Billion to CoreWeave in Equity and Cloud Spending Deal
Summary
Jane Street Group has taken a $1 billion equity stake in AI cloud provider CoreWeave at $109 per share and agreed to spend approximately $6 billion on the company’s technology offerings, the companies announced Wednesday — CoreWeave’s third multibillion-dollar commitment this month alone.
The deal gives the trading firm priority access to Nvidia’s next-generation Vera Rubin chips across multiple CoreWeave data centers, while also covering products that will help Jane Street build and deploy its own AI software. The combined $7 billion commitment — part equity, part cloud spend — signals that Wall Street’s most computationally intensive firms are moving aggressively to lock in dedicated GPU capacity before supply tightens further.
Jane Street previously held approximately 6.17 million CoreWeave shares, or roughly 1.5% of shares outstanding, according to Bloomberg data. The firm has separately invested in Anthropic across its Series E and F rounds and is reportedly in talks to co-lead a $1 billion investment in cloud startup Fluidstack at an $18 billion target valuation.
The deal also advances CoreWeave’s effort to reduce its dependency on Microsoft, which represented approximately 70% of its revenue last year. Earlier this month, Meta committed $21 billion to CoreWeave, and Anthropic agreed to spend multiple billions on its data center capacity.
Trading firms such as Jane Street rely on high-performance compute to power algorithms that execute market decisions in microseconds — a use case that demands the kind of dedicated, low-latency infrastructure that hyperscalers have struggled to reliably provide. Jane Street’s revenue in the first nine months of 2025 exceeded $24 billion, surpassing its prior full-year record.
