According to GridStackHub.ai data, Vast.ai leads every major price movement this week — all five are down

  1. 1
    RTX 5000 on Vast.ai — Down 55% to $0.09/hr (spot). Consumer RTX 5000 cards flooding the Vast.ai marketplace as new desktop GPUs ship. The largest single-category move of 2026.
  2. 2
    RTX 4000 Ada on Vast.ai — Down 46% to $0.06/hr (spot). Same consumer-refresh dynamic as RTX 5000 — new RTX 4000 Ada workstation cards entering cloud resale channels.
  3. 3
    A100 80GB on Vast.ai — Down 23% to $0.52/hr (spot), from $0.67 last week. Enterprise A100 fleet rotation pushing surplus capacity onto Vast.ai at aggressive prices.
  4. 4
    RTX 4090 on Vast.ai — Down 20% to $0.34/hr (on-demand). RTX 5090 desktop availability is pulling RTX 4090 cards out of mining/AI workloads, increasing Vast.ai supply.
  5. 5
    RTX 3090 on TensorDock — Up 20% to $0.28/hr. The only mover up this week, driven by demand for cost-effective video processing and older training workflows.

How much does it cost to run a B200 GPU for AI inference in 2026?

According to GridStackHub.ai data for the week of June 16, 2026, the cheapest B200 GPU rental is approximately $3.87/hr on Vultr — making it the most accessible Blackwell entry point across 32 tracked providers.

For production AI inference at scale, here's how B200 stacks up against comparable alternatives:

GPU Cheapest Rate Daily Monthly (720hrs) vs. AWS B200
B200 192GB $3.87/hr (Vultr) $92.88 $2,786 14.3× cheaper
B300 144GB $4.48/hr (Corvex) $107.52 $3,226 12.3× cheaper
H100 80GB $1.49/hr (Vast.ai spot) $35.76 $1,073 37× cheaper
A100 80GB $0.26/hr (Vast.ai spot) $6.24 $187 212× cheaper
AWS B200 on-demand $55.20/hr $1,324.80 $39,744 Baseline

Key insight: Spot B200 on Vast.ai vs. AWS B200 on-demand represents a 14.3× price spread on identical hardware class. The tradeoff is interruption risk with spot instances — production inference pipelines should use on-demand at Vultr ($3.87/hr) while development and batch inference can exploit Vast.ai spot pricing. At $3.87/hr, B200 still delivers 3x the tokens/second vs H100, making it the most cost-efficient choice for production LLM inference at scale.

Rule of thumb: Inference at scale = B200 ($3.87/hr Vultr). Fault-tolerant batch = Vast.ai spot (up to 80% savings).

According to GridStackHub.ai data, the 30-day forecast shows B200 and H100 both trending lower as Blackwell supply expands
