CoreWeave is a GPUaaS provider headquartered in New Jersey. They build or lease datacenters, buy GPU clusters from companies like Dell, and sell access to those clusters on a consumptive basis to customers. They were founded in 2017 as Atlantic Crypto and focused on mining Ethereum cryptocurrency using NVIDIA GPUs

Business model

In practice, CoreWeave’s unit of sale are whole clusters for fixed terms. CoreWeave customers rent a whole GPU cluster from CoreWeave for a term of four years on average;1 they prepay 15-25% of the total contract value up-front, then pay the remainder on a monthly basis.1 In exchange, CoreWeave will manage the hardware lifecycle and provide an SLA that guarantees you exclusive access to a subset of those GPUs (perhaps 95%) each month.

At the end of contract terms, CoreWeave repurposes Gen N-1 GPUs for inferencing.1

Technology

Hardware

CoreWeave uses Dell hardware for their GB200 NVL72 racks.2

Software

CoreWeave exposes GPU resources through a Kubernetes interface. As far as I know, there is no VM service, because their nodes are bare-metal.

LOTA (Local Object Transfer Accelerator is their in-house object storage cache.3

Customers

Microsoft is CoreWeave’s largest customer, which has allegedly committed $10 billion in GPU capacity between 2023 and 2030 over at least five different contracts.45 Microsoft accounted for $81 million (35% of CoreWeave’s revenue) in 2023 and $1.2 billion (62% of its revenue) in 2024, driven by a Master Services Agreement signed in February 2023.1

Other notable customers include:

  • Oracle Cloud5
  • Meta51
  • IBM is also using a CoreWeave cluster for training its Granite model.6
  • NVIDIA has also stated that it uses clusters in CoreWeave for internal R&D.4
  • Cohere1
  • Mistral1
  • Magnetar Capital, CoreWeave’s lead investor, also pays for GPU capacity from CoreWeave for its portfolio companies.1
  • Jane Street, also an investor, trains its models on CoreWeave clusters.1

CoreWeave will also be building a datacenter for Canadian sovereign AI in partnership with Cohere.7
