Goldman Sachs analysts Dominic Wilson and Vickie Chang have issued a warning that the current surge in AI investments may echo the 1999 internet bubble. In their report, they highlighted five key warning signals: peak investment spending, declining corporate profits, rising corporate debt, Federal Reserve rate cuts, and widening credit spreads. While the market has not yet reached the extremes of 1999, the analysts caution that the AI-driven investment frenzy poses growing risks of a similar market collapse.
