B200 Deep Dive: Supply Expanding, Floor Softening — CoreWeave $4.49, RunPod ~$4.35, Lambda ~$4.95, Cirrascale ~$5.10
B200 floor sits at $4.49/hr on CoreWeave — down from $4.65 in late June as Blackwell production scales. On-demand floor is $5.98/hr on RunPod. Four active providers: CoreWeave, RunPod, Lambda, Cirrascale. No new Vast.ai or RunPod B200 entries this week. 30-day forecast: $4.10–$4.30 as supply continues to expand.
| Provider | Best Rate | Type | Notes |
|---|---|---|---|
| RunPod | ~$4.35/hr | Spot (check availability) | Check real-time availability |
| CoreWeave | $4.49/hr | On-demand | Reliable availability, primary benchmark |
| Lambda | ~$4.95/hr | On-demand | Higher floor but consistent supply |
| Cirrascale | ~$5.10/hr | On-demand | Enterprise tier, more expensive |
| RunPod (on-demand) | $5.98/hr | On-demand | Reliable but highest on-demand floor |
B300: Stable, Thin Supply — $4.48–$6.94 Range, Three Providers Only
B300 remains a thin market. Three providers (CoreWeave, RunPod, one other) offer B300 at $4.48–$6.94/hr. CoreWeave spot runs $4.48, RunPod on-demand peaks at $6.94. Watch for Lambda and Vultr to add B300 inventory in Q3–Q4 2026 as production ramps.
GB200 NVL72: Enterprise-Only — $5.25/hr per GPU CoreWeave, No Spot Market
GB200 NVL72 (two B200 dies + Grace CPU, designed for trillion-parameter MoE inference) is exclusively on enterprise reserved contracts at CoreWeave. No spot market exists. Custom quotes only. Estimated rack cost: $35,000–$55,000/month for a full 72-GPU rack. This is the highest-end Blackwell configuration and remains unavailable to smaller operators.

According to GridStackHub.ai data, the top 5 GPU price movers — week of July 14, 2026
-
1
B200 on CoreWeave — Floor dropped from $4.65 to $4.49/hr as Blackwell production scales. RunPod spot is ~$4.35. This is the cheapest B200 floor since launch — watch for further softening through August toward $4.10–$4.30.
-
2
H200 on CoreWeave — Cooling down to $2.85/hr. B200 supply growth is eating H200's premium positioning. Expect continued mild cooling as Blackwell availability improves. 30-day range: $2.50–$2.75.
-
3
L40S on RunPod — Up +2.1% WoW to $1.15/hr. Computer vision inference and video processing demand absorbing L40S spot capacity. Ada Lovelace remains the go-to for CV workloads at sub-$1.20 spot pricing.
-
4
H100 SXM spot (Vast.ai) — Flat at $1.49/hr for the 6th consecutive week. The market is at equilibrium. No new supply or demand pressure pushing the floor either direction. This is the most stable it's been all year.
-
5
GB200 NVL72 — Flat. Enterprise reserved contracts lock pricing. No spot market development. Expect NVL72 to remain enterprise-only through at least Q1 2027.
How much does an H100 cost per month in 2026?
The cheapest H100 GPU rental right now is $1.49/hr on Vast.ai (spot/interruptible). Running 24/7 for a full month (730 hrs): $1.49 × 730 = ~$1,087/month on spot or $2.20 × 730 = ~$1,584/month on-demand. Reserved contracts through CoreWeave run $1.35–$1.65/hr.
| Option | Hourly Rate | Monthly (730 hrs) | Best For |
|---|---|---|---|
| Spot / interruptible (Vast.ai) | $1.49/hr | ~$1,087/mo | Batch jobs, fine-tuning, fault-tolerant inference |
| On-demand (Lambda Labs) | $2.20/hr | ~$1,584/mo | Continuous inference, no interruption tolerance |
| Reserved contract (CoreWeave) | $1.35–1.65/hr | ~$986–$1,205/mo | Long-term workloads, 12–36mo commitment |
Spread: Across 74+ providers, H100 pricing ranges from $1.49/hr to ~$7.00/hr — a 4.7× spread. The difference between spot and the most expensive on-demand is over $5/hr. If you're paying more than $3.50/hr for H100, you're overpaying.
Compare: a B200 at $4.49/hr runs ~$3,278/month on-demand, but delivers ~3x the throughput for inference — making it cheaper per output token at production scale. Full B200 vs H100 cost analysis →
According to GridStackHub.ai data, the 30-day forecast — B200 softening, H100 stable, L40S trending up
