Former NEC Director Gary Cohn: The market would be floundering without the AI energy trade

Summary

Gary Cohn warns that the AI infrastructure build-out is turning historically asset-light tech giants into asset-heavy, debt-financed companies with uncertain cash flows, creating a valuation problem similar to the fiber optic bubble. He believes compute will likely be overbuilt and become a commodity, benefiting later buyers rather than today’s heavy spenders. He notes the market’s dependence on the AI-energy trade and mentions quantum computing as a future disruption.

• Large tech firms (Magnificent Seven) are shifting from asset-light cash generators to asset-heavy AI capex spenders, reducing free cash flow.
• Valuations based on high-growth, cash-flow models may no longer apply; investors need a new valuation framework.
• Cohn sees a risk that AI compute infrastructure will be overbuilt and commoditized, repeating the fiber optic bubble where early builders (WorldCom, Enron) never monetized.
• He warns that just because companies want to dominate does not mean they will make money; the eventual buyers of distressed assets may capture the value.
• The stock market this year is almost entirely driven by the AI and energy trades; stripping them out reveals a negative market.
• Quantum computing is emerging and will require different infrastructure from current data centers, adding another layer of uncertainty for today’s AI capex plans.
