The Pre-Mortem: What a Market Correction Would Look Like

At 40:30 · chapter starts 36:40

When Dubner suggests a 20% market correction as the dark scenario for a pre-mortem exercise, Gensler gently corrects him: with stocks at 235% of GDP versus a 25-year average of 110–120%, there's a lot of room between here and dark. The real pre-mortem runs like this: chip and memory companies with gross margins of 70–80% face a price collapse as AI demand softens; data center construction grinds to a halt; neo-cloud companies that leased chips on leverage face insolvency; private credit is exposed. Warren Buffett's famous line applies — you find out who was swimming without trunks when the tide goes out. Gensler also identifies a second-order risk: if US frontier AI models keep raising prices, American companies will defect to cheaper Chinese models (DeepSeek, Qwen, Moonshot), undermining the entire premise of American AI dominance. He notes the S&P 500 contains hundreds of companies whose valuations implicitly assume they won't be disrupted — and AI's success means some of them will be.
