AI Investments Hit 17 Times Dotcom Bubble Scale; Global Debt Pileup Raises Systemic Risk

According to MarketWatch analysis, global financial markets are now built on high valuations, elevated leverage, and AI investment frenzy, with a structure similar to conditions before the 2000 dotcom bubble and 2008 financial crisis. AI-related investments currently total approximately 17 times the scale of the dotcom bubble and four times that of the 2008 subprime crisis period.

MarketWatch and McKinsey data show real estate values are overvalued by as much as 50% globally, while global stock prices may be overvalued by up to double their fair value based on the Shiller CAPE ratio. Meanwhile, real financial assets of $500 trillion support over $1 trillion in financial assets, yet for every $1 of new real asset investment over the past 20 years, $4 in debt has been added. Approximately 40% of US-listed companies and roughly 15% of global firms are unable to service debt principal, raising deleveraging risks if asset prices decline or volatility spikes.
