According to GridStackHub.ai data for the week of April 14–19, 2026, the cheapest H100 is $1.35/hr on RunPod (spot, community region) — while Vast.ai recorded the largest single-week average price drop in our 58-provider network this year, cutting rates 63.7% across 45 pricing records. This week's pulse covers 29 active providers and 368 GPU pricing records tracked across on-demand, spot, and reserved markets.
The headline numbers across the four most-tracked GPU classes:
| GPU | Cheapest Provider | Price/hr | Pricing Type |
|---|---|---|---|
| H100 80GB | RunPod | $1.35 | Spot (community) |
| A100 80GB | Vultr | $0.125 | On-demand (global) |
| H200 | RunPod (us-east-1) | $0.50 | On-demand |
| L40S | Vast.ai | $0.3846 | Spot |
A100 on Vultr at $0.125/hr is the most striking number in the table. On-demand, globally available, no commitment required. For teams running smaller inference workloads or fine-tuning jobs that don't need H100-class performance, this is a significant undercut versus the $0.78–$1.79/hr you'd pay elsewhere.
H200 at $0.50/hr on RunPod is the other standout. H200 carries 141GB HBM3e memory and 4.8TB/s bandwidth — it's the go-to for 70B+ parameter models. Finding it at $0.50/hr on-demand is the kind of pricing anomaly that closes fast. Check availability on the GridStackHub calculator before it disappears.

Counterintuitive? Yes. But the data is what it is. If you're running A100 workloads at scale, this is the window.

Virginia remains the gold standard for data center cost efficiency in our Stack Network Index, scoring 92/100. The practical implication: running an identical H100 cluster in California costs approximately $380,000/year more in electricity than the same cluster in Virginia. At scale, that's not a provider pricing decision — it's a geography decision.
