**Trader consensus on A100 GPU rental prices landing in the $0.75–$1.00 range by end of October reflects abundant supply in secondary marketplaces and spot segments.** As of mid-October 2026, on-demand medians across providers sit near $1.50–$2.00 per GPU-hour, yet cheapest listings on platforms like Vast.ai frequently fall to $0.47–$1.09, with spot rates even lower. This gap arises because newer H100/H200 and Blackwell GPUs absorb high-end AI training demand, leaving older A100 capacity available for inference, fine-tuning, and smaller workloads. Recent 30- to 90-day trends show modest declines or stability in medians, with no major supply shocks or demand surges reported. Resolution likely tracks an index weighted toward accessible rental rates rather than premium hyperscaler pricing, leaving little time before month-end for meaningful movement.
