The original post featured a video clip from the Future of Global Markets conference held on Oct. 21, quoting Griffin’s statement that “GPUs, like airlines, have a very low marginal cost to run” and that “the moment you have overcapacity, pricing goes into freefall.” Sharing the post, Burry wrote, “This is obvious to most with a working brain cell.” > This is obvious to most with a working brain cell. https://t.co/h5949eBkJM > > — Cassandra Unchained (@michaeljburry) October 26, 2026 **Read Also: Ken Griffin Calls AI a Bubble After Citadel Bought the Dip** ## **Broader AI Bubble Warning** Addressing the broader sector at the same time, Griffin stated investors are “almost certainly” in an AI bubble. He added that “any radical transformation of our economy is generally intertwined with a bubble.” Griffin also noted that corporate America is scrutinizing its bills and actively evaluating how to maximize the return on AI spending. ## **Burry’s Broader Bear Market Outlook** Burry’s remarks on GPU overcapacity follow his recent publications warning of broader market overvaluation. In an Oct. 18 X post sharing his Substack analysis, Burry examined the S&P 500 following its Oct. 6 record high. He categorized S&P 500 constituents into “Leaders,” “Broken” stocks (down 20-40% from their tops), and “Busted” stocks (down more than 40%). Burry suggested that “truly busted stocks” could be a “decent haven through the bear market, even if it lasts years.” Noting that “speculation has overrun investing” and that stock indices appear “overstretched,” Burry warned investors to prepare for the possibility of another “15-20 year period of negative or little real returns in stocks.” > For each of the ten market tops over the last 40 years, one will find a caldera of lava underneath the placid S.
