Trader sentiment on B200 rental prices at end-October reflects tight but easing supply amid surging AI inference and frontier model demand. Current marketplace rates cluster between $4.13 and $6.69 per GPU-hour, with medians near $6.11 across neocloud and enterprise providers. Hyperscalers maintain premiums through reserved capacity while spot and smaller platforms offer lower entry points. Production ramps at TSMC and growing HBM3e output are expected to add supply through Q4, yet persistent agentic workloads and multi-model training cycles could sustain utilization above 80 percent. The balanced odds across $5–$6.50 brackets capture uncertainty over whether incremental Blackwell volumes will outpace demand before October.
