This list is built from each provider's own pages and announcements. It shows who sells the platform, not who has free racks on your dates. Availability changes weekly, and some of the best options are operators that don't advertise.
Hyperscalers vs neoclouds
Hyperscalers (Azure, AWS, Oracle) sell GB300 inside their wider cloud. That's simpler if your data and contracts already live there, but large GB300 blocks usually go through account teams and long commitments. AWS, for instance, tells buyers to contact sales (AWS).
Neoclouds (CoreWeave, Nebius, Lambda, Crusoe and smaller operators) are built around GPU clusters. They tend to move faster on whole-rack reservations and bare-metal access. See Best Neocloud for a wider directory.
A lot of GB300 capacity is contracted before it's built. IREN's $9.7 billion agreement to deploy GB300 capacity for Microsoft is one example (IREN, Nov 2025). Racks that aren't already spoken for come free in bursts, which is why it pays to ask several operators at once.
What to ask every provider
- Will I get whole racks with the 72-GPU NVLink domain intact, or slices?
- Which fabric between racks, InfiniBand or Spectrum-X, and is it non-blocking at my size?
- Exact start date per rack, and what happens if delivery slips.
- Uptime commitment at rack level, and how failed trays are swapped.
- Bare metal, Kubernetes or Slurm, and who manages what.
- Storage throughput and data egress terms.
