**Trader sentiment for H200 GPU rental prices at end-October centers on sustained demand for memory-intensive AI workloads amid gradual Blackwell B200 supply growth.** Current neocloud on-demand rates cluster tightly around $3.80–$4.50 per GPU-hour, with marketplace spots like Vast.ai near $3.82 and providers such as Jarvislabs at $3.99, while hyperscalers remain far higher. Recent months have seen mixed moves—H200 spot prices dipped sharply earlier amid B200 ramp-up that displaces older Hopper capacity, yet overall contract pricing held firm due to HBM3e shortages and hyperscaler capex. Key swing factors include neocloud competition pressuring rates downward, persistent inference and training demand from large language models, and any acceleration in Blackwell availability that could free up H200 inventory. The closely matched probabilities around the $3.50–$4.50 band reflect uncertainty over whether supply relief or AI buildout will dominate by late October.
