Ray Dalio’s latest warning is blunt: the companies building the AI revolution could see their stocks fall by as much as 80% even if they succeed in changing the world. That jarring assessment came during a July 2026 interview with My First Million, as detailed in the original report. Dalio’s message lands at a moment when crypto markets are running hot on AI narratives, and his metric for reckoning—a bubble gauge sitting at 75% of the extremes seen in 1929 and 2000—demands attention from risk-asset traders.
The billionaire investor explained that during bubble periods, even the most successful companies can lose about 80% of their market value. He described how the excitement around major new technologies fuels investment, but promising prospects alone do not guarantee good stock returns. High starting valuations and a wave of new competitors typically erode the upside. That dynamic, Dalio says, is already baked into AI-related equities, leaving them vulnerable to a sharp repricing.
The Trigger That Could Prick the Bubble
Dalio’s historical research suggests bubbles deflate when investors are forced to convert paper gains into cash. The usual catalysts are tightening monetary policy or new wealth taxes. In 1929 and 2000, rate hikes and regulatory moves played central roles. Today, central banks are still navigating inflation risks, and any unexpected shift toward restraint could rapidly change the liquidity backdrop that has propped up AI valuations.
