Sep 17, 2026 · 18m

Summary

Brad Gerstner joins the show to discuss the state of the AI market, emphasizing that current valuations are driven by earnings rather than multiple expansion. He highlights the critical need for AI labs to hit specific revenue targets to justify massive infrastructure capex, while noting risks from potential interest rate hikes and regulatory challenges. Gerstner predicts a slower compute buildout than forecasted and advises investors to remain flexible, focusing on monthly revenue data and macroeconomic factors to navigate the next phase of the AI supercycle.
