Jane Street–CoreWeave Deal

Jane Street is treating artificial-intelligence computing like a supply contract, not a utility bill. On April 15, it agreed to spend about $6 billion with CoreWeave and bought another $1 billion of the company’s stock. (sec.gov) CoreWeave said the agreement is multi-year and expands an existing relationship. The company said it will give Jane Street access to next-generation systems across multiple facilities, including Nvidia’s Vera Rubin chips, plus the software and services needed to run models at scale. (coreweave.com) The stock purchase was priced at $109 a share for 9,174,311 Class A shares, or about $1.0 billion in cash, according to CoreWeave’s April 15 filing. Reuters reported that price was about 7% below CoreWeave’s prior close and lifted Jane Street’s total position to about $1.44 billion, making it one of CoreWeave’s largest shareholders. (sec.gov) (finance.yahoo.com) The basic business here is renting clusters of graphics processors, or GPUs, that train and run large artificial-intelligence models. CoreWeave sells that capacity by the chip-hour, along with networking, storage, and managed software, according to its public filing. (sec.gov) Jane Street said it uses machine learning in its research across global financial markets, training large models on “massive volumes of noisy data” and refining them continuously. That puts a trading firm into the same queue for scarce high-end compute as model builders and big consumer-tech companies. (coreweave.com) The timing matters because CoreWeave has spent April stacking giant contracts. On April 9, it announced an expanded agreement with Meta worth about $21 billion through December 2032, and on April 10 it announced a multi-year deal with Anthropic. (coreweave.com 1) (coreweave.com 2) Those wins also change who CoreWeave serves. A company that had been closely associated with artificial-intelligence labs and hyperscalers is now locking in a Wall Street trading house as a long-term compute customer and shareholder at the same time. (reuters.com) (coreweave.com) CoreWeave’s filings before its public listing showed why these long contracts matter. The company told investors it priced access to its platform on a per-GPU-per-hour basis and relied heavily on a limited number of customers, with Microsoft accounting for 62% of 2024 revenue in its S-1. (sec.gov) For Jane Street, the deal suggests compute is becoming part of market infrastructure inside quantitative trading, alongside data feeds and networking. For CoreWeave, it adds another customer willing to reserve capacity years ahead instead of buying it one job at a time. (coreweave.com)
