2026 Global ETF Outlook finds the market entering a new phase where execution matters as much as growth
As global ETF assets approach US$22 trillion, the ETF industry is entering a new phase where scale itself is creating new limits, and where infrastructure, capacity and execution will increasingly determine which strategies and issuers can grow. That is the central finding of State Street Corporation’s 2026 Global ETF Outlook, From Wrapper to Backbone.
After more than a decade of rapid expansion, the report finds that ETFs are no longer functioning only as investment products. Instead, they are becoming core components of how markets operate, influencing how asset managers launch funds, move assets, reach investors and manage liquidity across regions and asset classes.
As ETFs take on this larger role, State Street’s report highlights that growth is now bringing new pressures. Issues such as liquidity management, operational readiness, distribution mechanics and capacity constraints are becoming more important as ETFs expand into more complex strategies and broader use cases, including active, outcome-oriented and fixed income approaches.
“ETF growth has reached a point where scale changes the conversation,” said Joerg Ambrosius, president of Investment Services at State Street.
“The market is still expanding, but success increasingly depends on whether firms can operate at scale, manage complexity and execute consistently as ETFs take on a larger role in the financial system.”

“What’s encouraging is how adaptable the ETF model has proven to be,” said Jeff Sardinha, global head of ETF Solutions State Street. “Issuers continue to find new ways to use ETFs across asset classes and regions, and that flexibility is opening up opportunities that didn’t exist even a few years ago.”
The report also looks back at 2025, a year that helped clarify where ETF growth is truly coming from. With roughly US$2.4 trillion in global ETF inflows during the year, much of that momentum was driven by active strategies, which attracted more than US$600 billion as investors increasingly used ETFs for fixed income, outcome-oriented and risk-managed exposures. The Outlook notes that this correctly validated last year’s expectation that active ETFs would continue to gain share as assets scaled. At the same time, industry adoption in newer areas, particularly digital assets, proved more measured than anticipated, reflecting the need for further market infrastructure and regulatory clarity. Overall, the 2025 experience highlighted that as ETF assets continue to grow, operational readiness and execution are becoming as important as product innovation.
