Persistent memory shortages and sustained AI demand have kept RTX 5090 hardware prices elevated well above MSRP, yet cloud rental medians have already declined roughly 34% over the past year to around $0.58 per hour as more consumer-grade cards reach rental platforms. Traders see the $0.45–$0.55 range as the most probable outcome by end-September because incremental supply additions and spot-instance competition continue to exert downward pressure without any near-term relief in GDDR7 availability. No major new model launches or regulatory shifts are expected in the next two months to reverse this modest softening trend.
