**Balanced supply and demand dynamics for NVIDIA H100 GPUs are driving the tightly contested Polymarket odds across price brackets.** Recent data shows median on-demand rental rates holding steady near $3.30–$3.40 per GPU-hour through late September 2026, with a modest 10–14% year-over-year increase but little movement in the past month. Neocloud and marketplace providers continue expanding capacity, widening the spread from sub-$2.00 spot offerings to hyperscaler rates above $7.00, while sustained AI training and inference demand supports the floor. Newer Blackwell-series chips and additional data center deployments over the next eight weeks represent key swing factors that could shift availability or pricing by end of November. Traders appear to weigh these offsetting pressures evenly, reflecting uncertainty around near-term capacity additions versus persistent large-model workloads.
