**Sustained supply constraints and persistent demand for the Blackwell-based RTX 5090 are anchoring trader expectations for end-of-October rental rates at or above $0.60 per GPU-hour.** Launched in early 2025 with 32 GB GDDR7 and strong inference performance, the card faces ongoing shortages, with retail listings often exceeding $4,000–$9,000 amid competition from AI workloads and gaming. Current on-demand medians hover between roughly $0.55 and $0.70 across marketplaces like Vast.ai and RunPod, while spot/community tiers remain lower. The reported delay of next-generation GPUs to 2028 further supports elevated pricing by limiting near-term supply growth. With only weeks until resolution, modest fluctuations in utilization or provider capacity could still influence the final outcome, though recent trends show relative stability.
