Overview
CoreWeave started in crypto mining and turned its GPU fleet into an AI cloud. It's now the biggest neocloud, serving Microsoft, OpenAI and Meta among others, with a contracted backlog of $99.4 billion (Daloopa). It's known for running very large clusters well, which is why SemiAnalysis has rated it Platinum in every ClusterMAX edition.
Good fit if
- You need a large reserved cluster on one fabric.
- You want the provider with the longest record at this scale.
- You're comfortable with a sales-led, multi-month or multi-year contract.
Things to check
- Start date. Big customers take much of the new capacity. Ask when your exact allocation will be live.
- Facility. Most sites are leased from partners. Ask which building and whether it's running today.
- Small jobs. If you only need a few nodes, a self-service provider may be quicker.
