110 providers in viabandwidth's directory advertise B300 availability. The list below sorts direct operators first (own ASN, network-verified), then marketplaces and resellers. Each provider page shows claimed locations, pricing where published and any third-party hyperscaler capacity source.
Data updated September 2026. We list a provider here only if its own website advertises B300 availability. We do not infer model offerings.
An entry rate is the lowest hourly price a provider publishes across its whole GPU range. It is not necessarily the B300 rate, because operators publish one rate card for every accelerator they sell. Rows marked B300 only list no other accelerator, so for those the entry rate is the B300 rate. 28 of 36 were verified within the last 45 days. A further 1 provider quotes in another currency and is left out of this comparison rather than converted at a rate that would go stale.
