The report “2026 Global ETF Outlook: From Wrapper to Backbone” by State Street includes its now-traditional list of “clear and testable” predictions regarding the likely evolution of ETF markets in 2026. These forecasts highlight where momentum is building, where inflection points are emerging, and where change may arrive sooner—or later—than consensus expectations.
In total, the report presents 13 predictions for the North American ETF market:
1. U.S. ETFs Will Attract $2.1 Trillion in Net Inflows During the year, the ETF industry is expected to attract $2.1 trillion in inflows into U.S.-listed ETFs, surpassing the $1.49 trillion recorded at the end of 2025, according to ETF.com data cited by State Street. Global ETF inflows reached $1.9 trillion last year.
2. There Will Be More U.S. ETFs Than Mutual Funds The number of U.S. ETFs will exceed the number of mutual funds (excluding money market funds and fund-of-funds products), continuing an already established trend. The report notes that ETFs have become one of the dominant investment vehicles in North America due to their lower costs, tax efficiency, liquidity, and ease of use. They are also particularly popular among younger investors: ETFs represent 30% of Millennials’ portfolios on average. 26% for Generation X. 21% for Baby Boomers. Surveys indicate portfolio allocations to ETFs could rise by 20% or more across all age groups, including a 31% increase among Generation X investors.
