Sustained demand for NVIDIA Blackwell B200 GPUs in large-scale AI training and inference workloads has kept median on-demand rental rates near $7.15 per GPU-hour as of mid-September 2026, with recent transaction data showing modest upward drift over the past month. Supply constraints from HBM3e memory shortages, TSMC CoWoS packaging limits, and ongoing production backlogs have prevented meaningful price erosion despite incremental capacity additions by providers like CoreWeave and Lambda. Trader consensus around the $7.00+ outcome reflects the narrow window to year-end and limited near-term catalysts that could flood the spot market, though faster hyperscaler deployments or softer inference demand could still compress rates into lower brackets.
