en.Wedoany.com Reported - Amazon Web Services (AWS) has announced that, effective July 1, 2026, it will increase pricing for its Amazon EC2 Capacity Blocks for Machine Learning service by approximately 20%, marking the second price adjustment for the service in 2026. This service provides guaranteed access to GPU infrastructure reservations for AI training and inference workloads. AWS stated that Capacity Block reservation prices are updated periodically based on supply and demand, and customers pay the rate in effect at the time of purchase, even if the reserved capacity is used after future price changes.
The updated hourly accelerator reservation rates show that, across all commercial AWS regions (excluding GovCloud), P6-B300 is priced at $14.04, P6-B200 at $12.355; P5 in US regions is $5.191, outside the US at $4.72; P5e is $5.97; P5en in US regions is $6.865, elsewhere at $6.241; P4de in US regions is $2.214. AWS noted that all other Capacity Block pricing remains unchanged. Reservation fees are paid upfront at the time of booking, while operating system fees are billed separately based on the actual operating system used and instance runtime.
Amazon launched the EC2 Capacity Blocks service to provide customers with guaranteed access to scarce AI accelerator capacity without requiring long-term reserved instance commitments. The service supports scheduled reservations for NVIDIA Blackwell, Hopper, and Ampere GPU platforms, as well as AWS Trainium instances, helping organizations secure GPU infrastructure in advance for planned AI training and inference workloads. AWS previously raised Capacity Block pricing in January 2026, and this adjustment reflects ongoing market demand for dedicated AI computing resources.
AWS stated: "Reservation prices for Amazon EC2 Capacity Blocks for ML are updated periodically based on supply and demand."
