NVIDIA's reported mid-October shift of GB202 silicon exclusively to RTX Pro AI and professional cards has tightened RTX 5090 supply, with retailers pulling listings, Micro Center reclassifying stock as unavailable, and street prices surging past $6,000. This scarcity dynamic pits sustained AI-driven rental demand against limited existing inventory, creating uncertainty over whether hourly rates will climb above $0.70 or stabilize near current medians around $0.65–$1.36 by late November. Traders see closely matched odds across the $0.55–$0.75+ buckets because production halts often take weeks to fully constrain spot markets, while any slowdown in inference workloads or release of remaining channel stock could cap upside.
