Artificial intelligence is driving a surge of assets into thematic exchange-traded funds, but experts warn of the risks as tech stocks lead the market lower. Thematic ETFs can be volatile, delivering strong gains when a theme is in favor, but momentum may fade quickly.

ETFs focused on disruptive technology, including AI, have seen significant flows this year. The surge has lifted funds like the Global X AI & Technology ETF and the Robotics & AI ETF, attracting billions in assets and delivering strong performances.

Thematic ETFs require more research than traditional funds, with performance spreads among AI-focused ETFs reaching 60% this year. The ETF market has seen rapid growth, with close to 800 new ETFs launched in the first nine months of 2025, surpassing the total number of individual stocks traded in the U.S.

Despite recent market jitters, thematic investing can be worthwhile for investors who understand the risks. Themes can run quickly, so investors should seize moments of opportunity and consider taking profits. Thematic ETFs offer exposure to key technology trends, but investors should be prepared for short-term volatility. 1.
