Jane Street backs CoreWeave

Jane Street is putting about $7 billion behind CoreWeave, pairing a $1 billion stock purchase with roughly $6 billion of planned cloud spending. (bloomberg.com) CoreWeave and Jane Street said April 15 that the trading firm committed approximately $6 billion to use CoreWeave’s artificial intelligence cloud platform. CoreWeave said the agreement expands an existing relationship between the two companies. (coreweave.com) Quartz and Bloomberg reported that Jane Street separately bought about $1 billion of CoreWeave shares at $109 each, taking the combined package to roughly $7 billion. (qz.com, bloomberg.com) CoreWeave rents out graphics processing units, the chips used to train and run artificial intelligence models, through large data centers. Jane Street said the new capacity will support quantitative trading and research workloads that need fast access to those chips. (coreweave.com, thenextweb.com) The deal lands as CoreWeave keeps stacking large contracts with customers that want reserved computing capacity instead of waiting for open market supply. In its registration filing, CoreWeave said most of its revenue came from multi-year committed contracts and that customers often start large and expand over time. (sec.gov) CoreWeave went public in March 2025, selling 36.59 million shares at $40 and raising about $1.4 billion in net proceeds before expenses, according to its quarterly filing. That gave public investors a direct way to bet on the business of leasing Nvidia-heavy computing clusters to artificial intelligence customers. (sec.gov) The company has also been signing other large infrastructure deals this month. Quartz reported on April 9 that Meta expanded its CoreWeave cloud agreement to $21 billion, and Bloomberg reported on April 10 that CoreWeave’s $1.75 billion junk bond rallied after deals with Meta and Anthropic improved investor sentiment. (qz.com, bloomberg.com) For Jane Street, the commitment ties a trading firm more tightly to the same artificial intelligence infrastructure race that has pulled in Meta, Anthropic, and Nvidia. For CoreWeave, it adds another customer willing to lock in billions of dollars of future demand instead of buying chips and building those systems on its own. (bloomberg.com, coreweave.com)
