Traders see closely matched odds for B200 GPU rental prices by end of October because Blackwell supply ramps remain uncertain amid high AI demand. NVIDIA's production yields and packaging constraints continue to limit availability, while hyperscalers like Microsoft and Google accelerate custom silicon alternatives that could ease pressure on third-party rentals. Recent enterprise adoption reports and cloud provider capacity announcements have kept both the above-$6.50 and below-$4.50 outcomes near 30 percent, reflecting divergent views on whether hardware shortages persist or new capacity arrives in time. Key swing factors include any further delays in volume shipments and shifts in training workload forecasts through Q4.
