SemiAnalysis: cloud GPU capacity sold out through Sep 2026

SemiAnalysis data circulating on social media this week said global cloud GPU capacity is effectively sold out through August and September 2026, with the tightest availability centered on those two months. The post, shared on X by RosannaInvests, cited SemiAnalysis data showing one-year Nvidia H100 contract pricing at $2.35 per GPU-hour and said renewals are now extending into 2028. The claim fits with a broader picture SemiAnalysis has been publishing since early April. SemiAnalysis launched an H100 one-year rental price index on April 1 and described a market in which contract pricing had rebounded after a late-2025 trough, even as newer Blackwell systems were expected to add supply. ### How tight is the market the post is describing? August and September 2026 were identified in the circulating SemiAnalysis material as the hardest months to secure cloud H100 capacity globally. (semianalysis.com) The social-media post said “all cloud GPU capacity” was sold out through that window; based on the public SemiAnalysis material, that appears to refer to guaranteed contract and reserved cloud capacity rather than every possible spot or secondary-market listing. That is an inference from how SemiAnalysis frames its pricing index and rental-capacity work. SemiAnalysis’ April 1 report title — “The Great GPU Shortage – Rental Capacity – Launching our H100 1 Year Rental Price Index” — shows the firm was already tracking rental tightness as a standalone market condition. Its archive also places that report alongside later work on cluster economics and supply bottlenecks, suggesting the shortage has persisted rather than cleared. ### What is the most important number in this data? (semianalysis.com) March 2026 is the key datapoint because SemiAnalysis’ H100 one-year price index showed contract rates at $2.35 per GPU-hour, up from a low of $1.70 in October 2025. Multiple secondary reports citing the SemiAnalysis index described that as an increase of roughly 38% to 40% over six months. That matters because one-year pricing is closer to how serious enterprise and model-lab buyers lock in supply than headline on-demand listings are. (newsletter.semianalysis.com) SemiAnalysis built the index specifically around one-year H100 contracts, not only daily spot prices, which makes it a better gauge of where committed demand is clearing. ### Why are older H100s still getting more expensive? SemiAnalysis said in its April work that newer Blackwell deployments had not broken the pressure on Hopper-era systems. (semianalysis.com) Secondary reports citing the firm said demand from inference, media generation and multi-agent workloads was still pushing H100 contract prices higher even after the market had expected next-generation chips to ease conditions. Micron has also said its 2026 HBM volume is sold out under completed customer negotiations, according to reports of its fiscal first-quarter 2026 earnings call. That does not prove the cloud-capacity claim by itself, but it supports the idea that one of the critical upstream components for AI accelerators remains under long-term allocation pressure. (computing.net) ### What does “renewals extending into 2028” actually tell you? 2028 is significant because it suggests customers are not treating the shortage as a one-quarter problem. Reports summarizing the SemiAnalysis data said some H100 contracts signed two to three years ago were being renewed at original pricing, while other commitments were being extended four years out to lock in capacity. (fool.com) That points to a market where access, not just hourly price, is the scarce asset. In that kind of market, buyers with expiring allocations have an incentive to renew early rather than risk re-entering the queue later at higher prices or with no guaranteed supply. That conclusion is consistent with the SemiAnalysis pricing index and the renewal details cited in reports about it. ### Where should readers watch next? (moomoo.com) GB300 and broader Blackwell cloud rollouts are the next milestones to watch because SemiAnalysis and secondary reports both frame new Nvidia system deployments as the main potential source of relief. One report citing SemiAnalysis said Blackwell delivery timelines were already stretching into mid-2026, while the circulated post said August and September 2026 capacity was already spoken for. (semianalysis.com) SemiAnalysis’ public GPU Pricing Index and its April 1 rental-capacity report remain the clearest places to track whether H100 one-year rates move above $2.35 per hour, whether August-September tightness spills further into late 2026, and whether contract renewals continue to move into 2028.
