Goldman Sachs Warns of Valuation Fragility as AI Disrupts Long-Term Growth Outlook

Goldman Sachs has issued a warning regarding the current composition of U.S. equity valuations, noting that investor optimism surrounding artificial intelligence may be masking significant long-term risks. The brokerage suggests that the potential for AI to disrupt existing business models is forcing a critical rethink of long-term growth assumptions. The analysis focuses on 'terminal value'—the portion of a company's valuation derived from profits expected more than 10 years into the future. This metric is particularly critical for the software sector, where the ability to maintain competitive advantages over a decade is increasingly uncertain in the face of rapid AI evolution. According to the note released Thursday, terminal value now represents approximately 75% of the S&P 500's total equity value. This level is approaching a 25-year high, signaling a heavy reliance on distant future growth rather than immediate cash flows. Goldman analysts compared the current environment to the dotcom boom, suggesting that when long-term expectations become overly optimistic, the market becomes more susceptible to sharp corrections. This shift in perspective may lead institutional investors to re-evaluate their positioning in high-growth sectors that lack immediate, tangible profit catalysts.
