B200 GPU rental prices in 2026 reflect expanding Blackwell supply amid sustained AI demand for large language model training and inference. Current on-demand medians sit near $7.26–$7.93 per GPU-hour across providers, with spot rates as low as $3.20–$4.26 and cheapest on-demand listings at $3.49–$3.82 from platforms like Prime Intellect, Vultr, and Verda. Nebius raised B200 rates about 19% effective October 1, contributing to localized upward pressure while broader 90-day medians remained relatively flat. Competitive dynamics among neoclouds, marketplaces, and hyperscalers (where AWS lists exceed $14) continue to widen spreads, with increasing availability from more providers potentially capping further gains absent major demand surges.
