According to Bloomberg, Galaxy Digital founder Mike Novogratz stated at the Greenwich Economic Forum that AI is in "the biggest bubble of our lifetime," but advised investors to enter immediately, believing the bubble has not yet fully inflated. Bridgewater Associates founder Ray Dalio, speaking in Singapore, warned that AI is a "classic bubble" and is close to bursting, driven by rising interest rates and the demand to convert paper wealth into cash. Nassim Taleb, author of *The Black Swan*, believes the real risk lies in the bond market, not AI stocks themselves. Goldman Sachs data shows that the market capitalization of AI-related stocks now accounts for 42% of the S&P 500's total market cap, surpassing the 41% peak during the dot-com bubble in 1999. Goldman Sachs strategist Bobby Molavi's historical analysis found that bubble collapses typically begin with a shift in central bank policy, rather than a "spectacular" end.
