Michael Burry backs Ken Griffin’s warning that GPU prices could crash

Two of Wall Street’s best-known skeptics are now reading from the same script on AI chips. Michael Burry has publicly sided with Citadel founder Ken Griffin, who warned that GPU prices could collapse once supply outpaces demand. Burry skipped the diplomatic phrasing. On October 26, 2026, he said the risk is “obvious to most with a working brain cell.” The dark fiber comparison Griffin made his case at Citadel’s Future of Global Markets conference, held October 20-21, 2026. His main historical reference was the 2000 telecom fiber-optic bubble. That bust left behind what the industry called “dark fiber,” meaning cable that was installed but never lit up with traffic. Griffin’s concern is that GPUs could follow a similar arc, with surplus capacity crushing prices. He also compared GPU supply dynamics to the airline industry. Griffin didn’t stop at pricing. He said investors are “almost certainly” in an AI bubble when it comes to GPU demand. He also raised doubts about how long older GPU models stay useful. In a field where the technology moves this quickly, he questioned whether earlier chips remain economically viable for long. And if supply does run ahead of demand, Griffin argued G...
