Citadel's Ken Griffin Warns of AI Bubble and GPU Pricing Glut

Citadel founder Ken Griffin warned that financial markets are almost certainly in an artificial intelligence bubble, cautioning that an emerging GPU glut could trigger severe price collapses. Speaking at recent events, Griffin compared GPU dynamics to airline seats and the 2000 telecom crash, citing low marginal operating costs and uneven corporate productivity gains. However, he advised against selling AI equities entirely, predicting transformative leaders will endure. SEC filings reveal Citadel trimmed its Nvidia stake by 37% while holding $2.36 billion in the chipmaker alongside $2.59 billion in Amazon, amidst broader industry concerns over hyperscalers' heavy capital expenditures.
