Jane Street signs $13bn five-year AI cloud deal with Crusoe

A proprietary trading firm has just signed one of the largest AI cloud contracts of the year. Jane Street is committing roughly $13bn over five years to Crusoe, the data centre company, for clusters of AI chips and the infrastructure around them.

The terms were first reported by Bloomberg, citing people familiar with the arrangement, and it gives Crusoe the most prominent customer its cloud business has landed.

What makes it unusual is who is buying. Jane Street trades securities rather than selling software, and it has now contracted more AI compute than most model developers ever will.

This is its second such deal in short order. The firm signed a $6bn cloud contract with CoreWeave and put $1bn of equity into the company, which takes its committed spending across two suppliers to around $19bn.

Quantitative trading has always been compute-hungry. Pricing models, risk systems and signal research run on the same hardware that trains language models, and a firm at Jane Street’s scale would rather lock in capacity than bid for it later.

The scale still reframes who the customers are. AI infrastructure has been sold as a market for labs and hyperscalers, and a trading house quietly outspending most of them changes the shape of that demand.

Jane Street has been buying into the supply chain as well. It led a $700m round in the chip designer Etched at a $21bn valuation, which is a different kind of position from renting servers.

For Crusoe, the contract arrives at a useful moment. The company has been raising about $3bn at a valuation near $30bn, and a signed five-year commitment of this size is the strongest evidence a private data centre operator can show an investor.

The two events are connected more directly than that. Bloomberg also reported last week that Crusoe was seeking a chip loan backed by its contracts with Jane Street, which means the agreement was collateral before it was public.

That pattern is now standard in this cycle. Contracted revenue gets pledged against the debt that buys the hardware to service the contract, and the whole structure holds as long as the customer keeps paying.

Crusoe sits in a crowded new category. It competes with CoreWeave and with Nscale, which is seeking a $51bn US listing on contracted revenue that has largely not arrived yet, and all of them are selling the same promise of capacity delivered sooner than a hyperscaler can.

A contract this size cuts both ways for a company that size. Five years of committed revenue is what makes the debt affordable, and it also concentrates a large share of the business in one counterparty.

Crusoe is not short of demand elsewhere. It signed new AI computing deals with Meta earlier in the year, having built its business on powering data centres with energy that would otherwise be wasted.

Neither side has said where the capacity will sit. The chips, the sites and the delivery schedule are all undisclosed, as is whether any equity accompanies the contract the way it did with CoreWeave.

The company’s origins are unusual for a cloud provider. It started by putting computing next to stranded and flared energy rather than building on the grid, an approach that gave it power at a moment when power became the binding constraint on AI capacity.

The financial detail is similarly thin. The figure is approximate, sourced to people familiar rather than to either company, and neither Crusoe nor Jane Street has confirmed it publicly.

What the deal does confirm is a shift in who is competing for chips. When a trading firm can commit $13bn to compute without needing a model to sell, the constraint on AI infrastructure is not demand from AI companies.
