**B200 rental prices have climbed steadily through late 2026 amid tight Blackwell supply and surging demand for frontier AI training and inference.** Median on-demand rates currently sit near $7–8.50 per GPU-hour across providers, with spot and marketplace listings ranging from $4–5 at the low end to $10+ on premium or hyperscaler instances. Recent data show 20–30% gains over the past 90 days, driven by high utilization at AI labs and neocloud operators, limited new capacity coming online, and NVIDIA’s production constraints. Traders watch indices like Ornn and Silicon Data for resolution signals, as additional Blackwell volume and any demand moderation from large-scale model deployments could pressure rates before year-end.
