AI overview

Citadel founder Ken Griffin warns investors that an AI bubble is almost certain, predicting a GPU price collapse due to oversupply. He compares GPUs to airplane seats, arguing that both AI models and telecom infrastructure have very low marginal running costs, meaning prices can collapse once supply exceeds demand, citing the 2000 telecom boom as a historical parallel.

    Ken Griffin says investors are in an AI bubble, comparing GPU supply to airline seats

    Report first recorded Oct 22, 05:46

    Citadel founder Ken Griffin said investors are "almost certainly" in an AI bubble, but noted that companies surviving such bubbles often lead markets for decades. He warned that a chip glut could cause GPU prices to fall sharply, similar to fiber-optic cable prices after the 2000 telecom overbuild. Griffin added that corporate buyers are comparing premium models from OpenAI and Anthropic against cheaper open-source alternatives, straining labs' spending.
