**Stable spot-market supply on platforms like Vast.ai has anchored A100 rental rates near the $1.00–$1.25 band as October closes.** As of late October 2026, on-demand medians hover around $1.40–$1.88 per GPU-hour across providers while spot and community listings frequently clear between $0.40 and $1.00, reflecting ample decentralized capacity that offsets tighter enterprise contracts. AI inference and fine-tuning workloads sustain baseline demand for the Ampere architecture’s 80 GB HBM2e without triggering the sharp spikes seen in newer Blackwell or H100 segments. Flat 90-day price trends and no major supply disruptions or hyperscaler procurement surges in the past week reinforce trader consensus around the leading outcome, with resolution on October 31 now just days away.
