15 GPU list prices rose in September and none fell. Today AWS raises Capacity Blocks 15%

In September 2026 we compared 176 posted on-demand GPU prices, each cloud's own published rate for each GPU it rents, between the first three and the last three days of the month. 15 ended the month higher, none ended it lower, and the other 161 did not move.

Today, October 7, AWS adds an increase of its own to EC2 Capacity Blocks for ML.

Everything below comes from the daily prices FastGPU records across GPU clouds, published as an open dataset, and from AWS's own pricing page. Every figure links to the page it comes from.

15 increases, no cuts

All 15 came from two providers: Verda (10) and RunPod (5). Marketplaces, where each host sets its own price, are not part of this count.

The typical price rose less

The median of each provider's lowest posted on-demand price, counting only the providers that posted a price on all six of those days, so a provider joining or leaving never reads as a price move:

GPU Sep 1 to 3 Sep 28 to 30 Change Providers
H100 SXM $3.55 $3.70 +4.3% 16
H200 $4.14 $4.38 +5.7% 14
B200 $6.18 $6.25 +1.1% 12
A100 80GB $1.79 $1.79 -0.1% 15

The cheapest offer moves both ways

The floor, the lowest posted on-demand price outside the hyperscalers (geometric mean of the first three days against the last three), is set by one or two providers at a time, so it swings:

So the list prices at the larger GPU clouds drifted up while the cheapest deal stayed a moving target. For a job of a few hours, the floor is what you pay; for a quarter's budget, the list-price trend matters more.

Same card, 44.0x apart

On September 30 a V100 cost from $0.07/hr at Vast.ai to $2.95/hr at Oracle Cloud across 8 providers: $2.95 / $0.067 (the low before rounding) = 44.0x. It was the widest spread of the month: the same card, 8 sellers.

AWS Capacity Blocks: 15% more from today, up to 26.5% outside the US

AWS's Capacity Blocks pricing page says:

Effective October 7, 2026, hourly rates per accelerator across all available AWS Regions will be: P6-B300 at $16.146 ($16.819 in AWS GovCloud Regions), P6-B200 at $14.208 ($14.801 in AWS GovCloud Regions), P5en at $7.895, P5e at $6.866, P5 at $5.970, P4de at $2.546, and P4d at $1.696.

Against the rates AWS published before, as recorded in our price-change log, per GPU per hour:

Instance GPU Before From Oct 7 Change
P6-B300 B300 $14.040 $16.146 +15.0%
P6-B200 B200 $12.355 $14.208 +15.0%
P5en, US Regions H200 $6.865 $7.895 +15.0%
P5en, Europe and Asia Pacific H200 $6.241 $7.895 +26.5%
P5e H200 $5.970 $6.866 +15.0%
P5, US Regions H100 SXM $5.191 $5.970 +15.0%
P5, Europe, Asia Pacific and South America H100 SXM $4.720 $5.970 +26.5%
P4de A100 80GB $2.214 $2.546 +15.0%
P4d A100 40GB $1.475 $1.696 +15.0%

AWS now charges one rate in every Region, so blocks that used to be cheaper outside the US (P5 and P5en) rise the most. AWS publishes these rates to a tenth of a cent; our log shows them rounded to the cent. AWS also says Capacity Block reservation prices are dynamic and are updated periodically based on supply and demand, and: "All other EC2 Capacity Block prices, as well as prices on fixed pricing models like On-Demand and Savings Plans, remain unchanged."

What it means if you rent

  • A Capacity Block is reserved capacity: you book a start date and a length, and AWS guarantees the GPUs for it. That is a different product from an on-demand GPU you can stop at any time. Still, for scale: the cheapest posted H100 SXM is $1.79/hr at Vast.ai as of 2026-10-07 01:46 UTC, the September-end median across 16 providers was $3.70/hr, and a P5 Capacity Block is now $5.970/hr.
  • If you were planning a reserved block, re-run the numbers: the reserve-or-rent calculator has the October 7 rates, and the GPU cluster page prices N GPUs for M months across providers' published term rates.
  • List prices change without notice. A price alert emails you when a GPU drops below a price you choose, with no account.

Data and method

Posted prices, not transactions. The September report is computed from the recorded daily prices once the month is over and then frozen; every dated change is in the price-change log, also as JSON at https://fastgpu.co/api/v1/price-changes. The daily series is an open dataset (CC BY 4.0). Live prices in this post are as of 2026-10-07 01:46 UTC; the linked pages show the current ones. Some provider links on FastGPU are affiliate links; tables and every "cheapest" figure are ordered strictly by price.
