**The Ornn Compute Price Index (OCPI-A100) settled at $0.88 per GPU-hour on September 30, 2026, locking trader consensus into the $0.75–$1.00 range.** This outcome reflects sustained downward pressure on A100 rental rates across neocloud marketplaces and spot platforms, driven by abundant supply as operators shift workloads to newer accelerators like H100 and B200 while older A100 clusters enter secondary markets. Daily transaction data showed consistent declines through late September, with the index falling roughly 14% over the prior 30 days amid steady on-demand availability from providers such as RunPod, Vast.ai, and hyperscaler spot instances. Realistic scenarios that could still disrupt this positioning include a sudden spike in large-scale AI training demand or unexpected constraints on newer GPU capacity that push users back to A100 fleets.
