Weekly Market Recap – August 17, 2026

It is becoming more difficult for investors to find ways to diversify away from AI exposure as it commands a growing share of public and private markets. Hyperscalers, with a seemingly never-ending appetite for fresh capital, have tapped nearly every corner of the capital markets – raising both equity and debt – to fund the AI capex buildout. As a result, market concentration in the tech sector, which is increasingly tied to AI, has risen with no signs of slowing down. According to J.P. Morgan Global Research, the cumulative price tag for the buildout is expected to reach $5.5tn by 2030, suggesting that elevated concentration in tech could persist for years. This could leave portfolios acutely exposed to heightened bouts of volatility if challenges arise. Potential challenges include slower AI adoption, delays in upgrading the electrical grid to power data centers or AI companies missing earnings forecasts.
