Key Takeaways
- • Michael Burry endorsed Ken Griffin's warning that an AI-driven GPU oversupply could push computing rental prices into 'freefall', calling the argument 'obvious to most with a working brain cell' in an X post.
- • Griffin, speaking on Bloomberg Talks, drew a parallel to the telecom fibre overbuild around 2000, warning that marginal GPU pricing could collapse if supply exceeds demand.
- • Nvidia and AMD could see weaker orders, and CoreWeave would be most directly exposed because GPU rentals are central to its business; CoreWeave debt yields have reportedly reached 15%.
- • Current rental data points the other way: Social Capital reportedly cited a 45% rise in H100 rental costs since December, which Chamath Palihapitiya attributed to electricity constraints.
Summary
Michael Burry has publicly backed Citadel founder Ken Griffin's warning that the artificial intelligence boom could end in a collapse of GPU rental prices, according to the International Business Times UK. In an X post on a Monday, Burry wrote: 'This is obvious to most with a working brain cell,' endorsing the view that an oversupply of AI chips could sharply depress rental prices and undermine the economics of companies investing heavily in computing infrastructure.
Griffin raised the concern the previous week on Bloomberg Talks, drawing a comparison with the telecommunications infrastructure boom around 2000. 'We built more fibre than we had demand for, and the price of telecommunications just went straight down,' he said. He argued that if GPU provisioning exceeds demand, 'marginal pricing will actually go into freefall.' The economics hinge on the fact that once GPUs are installed, the incremental cost of renting out spare capacity for an additional hour is relatively low, so providers facing excess capacity may cut prices to keep equipment utilised.
Such a downturn could hit Nvidia and Advanced Micro Devices through weaker orders, while specialised cloud providers such as CoreWeave would be exposed more directly. The article notes that Nvidia's gross margin fell to 56.9% in fiscal 2023 from 64.9% a year earlier, even as revenue stayed broadly flat at $27 billion, illustrating how quickly profitability can deteriorate when demand weakens. Nvidia has since maintained gross margins above 70%, reaching 75% in the quarter ended July 2026.
Current pricing does not yet show an oversupply. Social Capital reportedly highlighted that the cost of renting Nvidia's H100 GPUs had risen 45% since December, despite the chip being available since 2022 and two newer generations having reached the market. Social Capital founder Chamath Palihapitiya attributed the strength to electricity constraints, arguing that power availability remains a significant obstacle to adding capacity.
CoreWeave's operating margin dropped markedly in 2025 compared with 2024, leaving little cushion if rental rates weaken. Blackstone President and COO Jon Gray discussed the economics of specialised cloud providers on Bloomberg Talks, describing their underlying business as strong while stressing the importance of delivering capacity. Bloomberg Talks host Dani Burger noted that yields on some of CoreWeave's debt had reached 15%, underscoring financing pressure across parts of the AI infrastructure sector. A sustained fall in rental prices could make it harder for operators to cover financing and operating costs, potentially reducing their willingness to buy additional chips.
