Current median on-demand B200 rental rates sit near $6.7–$6.8 per GPU-hour across neocloud indices, with listings spanning $3.50 at the low end to over $14 at hyperscalers. Modest price increases of roughly 5–6% over the past week and 20% over the past month reflect sustained AI training and inference demand outpacing the gradual ramp of Blackwell supply through additional providers. Competitive dynamics hinge on capacity fragmentation—lower-cost neocloud and marketplace offerings versus premium enterprise allocations—plus utilization rates and any late-September capacity releases that could widen spreads or stabilize the central $6.50–$7.00 band favored by traders.
