AI, Not ESG, Is Driving the Revival in Sustainable ETFs – First Trust NASDAQ Clean Edge Smart Grid Infras
After more than three years of relentless investor withdrawals, U.S. sustainable ETFs finally staged a comeback in the second quarter of 2026.
But the recovery has less to do with a renewed passion for environmental, social and governance (ESG) investing than with one of Wall Street’s hottest themes: artificial intelligence.
According to Morningstar, U.S. sustainable funds attracted nearly $3 billion in net inflows during the second quarter, ending a streak of 14 consecutive quarters of outflows dating back to early 2022. The inflows, coupled with rising markets, pushed total sustainable fund assets to a record $398 billion.

However, the rebound was highly concentrated rather than broad-based.
AI Is Creating New ESG Winners
GRID’s recent success illustrates how the investment case for sustainable ETFs is evolving.
Rather than relying on traditional clean-energy themes, the ETF focuses on companies helping modernize the electric grid — an increasingly critical investment as electricity demand surges from AI data centers.
The trend reflects what many market strategists have described as the “second wave” of AI investing, in which capital is flowing beyond chipmakers such as Nvidia into companies supplying the infrastructure needed to power the AI boom.
Other Tailwinds
Apart from AI, there are other forces that are supporting sustainable ETFs.
Morningstar noted that geopolitical tensions in the Persian Gulf pushed oil prices above $100 per barrel, prompting governments and businesses to accelerate investments in alternative energy sources and grid resilience.
Renewable energy companies also benefited from this shift.
Is ESG Really Back?
Despite the encouraging headline numbers, Morningstar’s data suggests investors are being selective rather than embracing the entire sustainable investing universe.
The return to positive flows was concentrated in a small group of passive ETFs tied to electrification, grid infrastructure and renewable energy, areas directly benefiting from AI-driven power demand and growing energy security concerns.
Rather than signaling a full-fledged ESG revival, the inflows point to a more targeted trend. Investors appear to be favoring sustainable ETFs positioned to benefit from AI’s soaring electricity demand and the buildout of power infrastructure.
