Goldman Sachs: AI-related companies account for approximately 40% of the market capitalization of the S&P 500

The AI wave is breaking the traditional asset diversification logic of pension and sovereign funds, with risks spreading from technology stocks to multiple areas such as private equity, corporate bonds, and infrastructure. Institutional investors are beginning to reassess the AI exposure of their entire portfolios.

Goldman Sachs estimates that AI infrastructure-related companies account for about 40% of the total market capitalization of the S&P 500; Apollo data shows that this year, AI-related issuances have accounted for nearly half of the investment-grade bond issuance and 87% of venture capital funding. Monte Tarbox, Chief Investment Officer of the New York City Retirement System, recently rejected a fundraising request due to an overweight position in a private equity fund related to AI.

Institutions currently face the challenge of lacking a unified standard for measuring AI exposure. The Los Angeles County Employees Retirement Association estimates that 8% to 19% of its holdings are related to AI; a survey by Invesco of 90 sovereign wealth funds shows that more than half list market concentration as the primary risk of AI investment. Some large institutions are beginning to adopt a holistic portfolio approach to track AI-related exposure and the correlations between assets, while some institutions are starting to use AI tools to monitor their own portfolios.
