CoreWeave and Nvidia have signed an agreement that will see the latter take up CoreWeave's unused compute capacity.

As reported by Reuters, the deal has an initial value of $6.3 billion and will see the chip designer purchasing any residual cloud capacity not sold to other customers.

In an SEC filing, CoreWeave said: "Under the terms of agreement, in instances where the company’s data center capacity is not fully utilized by its own customers, Nvidia is obligated to purchase the residual unsold capacity through April 13, 2032, subject to any termination described below and satisfaction of delivery and availability of service requirements."

How much compute this is likely to comprise has not been shared. Nvidia has previously signed agreements with CoreWeave to lease compute capacity.

The news follows reports that Nvidia had signed a $1.5bn deal to lease back its own chips from AI cloud provider Lambda last week. This would comprise up to 18,000 GPUs over the next five years.

Earlier today, reports emerged that Nvidia was scaling back its ambitions for DGX Cloud, which previously aimed to compete with its cloud customers, claiming that DGX Cloud would instead be used by Nvidia's own researchers.

This has, however, been disputed by Nvidia's DGX Cloud head Alexis Black Bjorlin, who said "DGX Cloud is fully utilized and oversubscribed, and we are expanding its scale.”
