Summary
Investment professionals remain bullish on artificial intelligence despite macroeconomic headwinds, with a Natixis Investment Managers survey indicating robust conviction in sector acceleration through year-end 2026. The survey found that 91% of respondents view AI as the primary driver of market performance, even as geopolitical tensions and inflation pressures persist. This strong consensus reflects confidence that AI adoption will generate meaningful economic productivity gains—88% of experts anticipate these improvements will materialize as higher corporate profitability in 2026.
However, the survey reveals material unease about concentration and systemic risks. An overwhelming 85% of specialists cite concentration risk as a key concern within the AI sector, acknowledging the disproportionate weight of mega-cap technology holdings in equity indices. Additionally, 79% of respondents warn that volatility driven by AI-related concerns could spread contagion effects to broader market segments. Only 12% of strategists forecast a bubble collapse in the remainder of 2026, suggesting skepticism remains limited but non-negligible.
Inflation concerns have escalated dramatically among the professional community. An extraordinary 97% of strategists identified inflation as the top risk for the second half of 2026, marking a substantial 18-percentage-point increase from 79% of respondents in the prior year's survey. This shift indicates growing worry that persistent price pressures could derail monetary policy accommodation and dampen equity gains. Reflecting this concern, 48% of specialists no longer classify U.S. Treasuries as a reliable safe-haven asset, while 55% view investment-grade credit as better positioned to provide portfolio protection.
Looking forward, positioning expectations favor U.S. equities, with 67% of respondents forecasting outperformance in H2 2026. Within equity allocations, 76% expect large-cap securities to outpace small-caps, and 82% prefer growth-oriented investments over value strategies—a positioning consistent with the AI-driven narrative dominating institutional asset allocation decisions.
