B200 and B300 Prices Hit All-Time Highs as Demand Outpaces Blackwell Supply

The Blackwell era was supposed to ease GPU pricing pressure. Instead, the opposite has happened: spot and contract rates for B200 and B300 capacity have climbed to all-time highs, with B300 hourly pricing up more than 40% since its January launch and B200 rates following close behind.

For teams planning training runs or scaling inference fleets in the next two quarters, the dynamics behind this matter more than the headline numbers.

What's driving the squeeze

Three forces are compounding at once.

Reasoning models changed the demand curve. Inference-heavy reasoning workloads consume far more compute per query than classic chat-style serving. The B300's 288GB of HBM3e makes it the natural home for long-context reasoning inference, and buyers have responded. Capacity that was expected to serve training demand is being absorbed by inference fleets instead.

Rubin anticipation froze the secondary market. With Rubin on the horizon, large holders of Blackwell allocation are locking in long-term contracts rather than releasing capacity to spot markets. Less spot supply means spot prices clear higher — and contract pricing follows.

HBM remains the hard ceiling. CoWoS packaging capacity has expanded, but HBM3e output is still the binding constraint on B300 production. Every GB300 NVL72 rack ships with over 20TB of HBM, and memory suppliers are sold out through mid-2027.

The numbers

• B300 hourly rates on major marketplaces are up 40%+ from January launch pricing
• B200 spot pricing has recovered past its 2025 peak, despite a full year of production ramp
• Multi-year reserved contracts for GB300 NVL72 racks are closing at premiums to list that would have been unthinkable during the H100 glut of early 2025
• H200 pricing, by contrast, has stayed flat — the squeeze is specific to Blackwell

What this means for buyers

If you need Blackwell capacity in the next six months, reserve now. The spot market is the most expensive way to access B200/B300 today, and the premium is widening. Reserved capacity at today's contract rates will look cheap by Q1 2027 if current trends hold.

Consider whether you actually need B300. For many training workloads, B200 — or even well-priced H200 capacity — delivers better cost-per-token-trained. The B300 premium is justified for long-context inference and memory-bound workloads, less so for compute-bound pretraining.

Geography matters more than ever. Pricing pressure is most acute in U.S. regions. Capacity in India and the Middle East — where new data center buildouts are coming online faster than local demand is absorbing them — is clearing at meaningful discounts to U.S. rates for identical hardware.

Our take

Record Blackwell pricing isn't a temporary spike — it's the market repricing compute for the reasoning-model era. Supply will catch up, as it always does, but not before Rubin resets the cycle again.

NovaCore's Hyderabad Blackwell cluster has B200 and B300 capacity available for reservation at rates well below U.S. spot. If you're planning a deployment, talk to us before the next price leg up.
