Billionaire Michael Burry Sends Investors a $1 Billion Warning About the AI Boom. History Says the Stock Market Will Do This Next.

News Summary
Michael Burry, the hedge fund manager famous for his bet against subprime mortgages before the 2008 financial crisis, is sending a $1 billion warning about the AI boom by shorting two popular artificial intelligence (AI) stocks. His hedge fund, Scion Capital Management, has placed 66% of its $1.4 billion portfolio in put options on Palantir Technologies and another 14% on Nvidia, signaling his expectation for these stocks to decline. Since ChatGPT's launch in November 2022, shares in Palantir and Nvidia have surged by 2,000% and 1,300% respectively, while the S&P 500 has gained 75% (20% annually), drawing comparisons to the dot-com bubble. The article highlights that in October 2025, the S&P 500's cyclically adjusted price-to-earnings (CAPE) multiple hit 39.5, its highest level in a quarter-century, a level only surpassed during the dot-com bubble historically. Data suggests that after CAPE ratios above 39, the S&P 500 has historically declined by an average of 30% over the next three years. Investors are advised to exercise caution, avoid absurdly valued stocks, and consider building cash positions to capitalize on future drawdowns.

The Cyclically Adjusted Price-to-Earnings (CAPE) ratio is a valuation measure for the stock market, smoothing out business cycle effects by dividing real stock prices by the average of ten years of inflation-adjusted earnings.
In-Depth AI Insights
Is Michael Burry's bet merely a quantifiable warning about an AI bubble, or does it reflect deeper macroeconomic concerns? - While Burry's short positions on Palantir and Nvidia directly target valuation excesses in the AI sector, the underlying logic might be similar to his 2008 short, which involved identifying systemic risks. - The current high CAPE ratio isn't solely linked to the frenzy around AI stocks; it could also reflect a broader phenomenon of capital flowing into risk assets in a generally low-interest-rate environment (even with recent hikes, rates remain historically low). - His warning may suggest that the trigger for an AI bubble burst might not be issues with AI technology itself, but rather broader macroeconomic factors such as monetary policy tightening, global economic slowdowns, or geopolitical uncertainties. What are the key similarities and differences between the current market environment and the dot-com bubble era that investors should heed? - Similarities: Overstretched valuations (CAPE ratio at historical highs), speculative fervor in a specific tech sector (AI vs. internet), high retail investor participation, and rapid stock price appreciation. - Differences: Current AI technology is demonstrating real-world applications and revenue growth across various industries, whereas many companies during the dot-com bubble lacked viable business models. Overall, corporate profitability and balance sheets may also be healthier now than during the dot-com era. - Investors need to distinguish between fundamental AI growth and speculative valuations, and be wary of risks to non-leading AI companies under a "winner-takes-all" dynamic. If Burry's prediction of a 30% S&P 500 decline over three years comes true, how would this impact President Donald Trump's economic policies and re-election prospects? - A significant stock market downturn during President Trump's second term would severely challenge his "America First" economic agenda, particularly regarding boosting U.S. economic confidence. - A market decline could lead to reduced consumer wealth, impacting spending and investment, potentially prompting the Trump administration to pursue more aggressive fiscal stimulus or advocate for Federal Reserve rate cuts to support the economy. - Stock market performance is often seen as a barometer of presidential effectiveness; such a decline would negatively affect his efforts to secure re-election in 2028 or endorse a successor, potentially fueling public discontent with economic management.
