NEW YORK, October 17, 2025 — In a landmark moment for the investment industry, U.S.-based exchange-traded funds (ETFs) have seen inflows surpass $1 trillion in 2025, reaching the milestone at a record pace, according to State Street Investment Management.

The inflows, which crossed the trillion-dollar mark earlier than ever before, position the ETF industry to potentially reach $1.4 trillion in new investments by year-end, cementing ETFs’ dominance over traditional mutual funds as the preferred investment vehicle among both retail and institutional investors.

Historic Surge in ETF Investments

State Street’s report highlighted that virtually every asset class within the ETF sector is experiencing growth, from broad market index funds to cryptocurrency and gold-linked ETFs. The trend underscores investors’ growing preference for low-cost, transparent, and liquid investment products.

“This year’s momentum is unprecedented,” said Matthew Bartolini, Global Head of Research Strategists at State Street. “Even if markets face a correction, the underlying shift toward ETFs is structural — it’s not slowing down.”

In comparison, ETFs did not reach the $1 trillion inflow mark last year until December 11, 2024, showing that 2025’s pace is roughly two months ahead.

Mutual Fund Outflows Continue to Fuel ETF Demand

The ETF boom coincides with a massive exodus from traditional mutual funds, which have seen outflows of $481 billion during the first nine months of 2025, according to Morningstar.

Michael Venuto, Chief Investment Officer at Tidal Financial Group, said that the migration is accelerating as asset managers adapt to the ETF model.
“What’s remarkable,” Venuto noted, “is that this growth continues despite heightened market uncertainty. We’re talking daily with managers converting mutual funds to ETFs or launching new ones — the demand is extraordinary.”

Experts say that the mutual fund industry’s higher fees, tax inefficiency, and limited liquidity have made ETFs the preferred choice for both active and passive investment strategies.

ETF Market Outlook: Expansion and Innovation Ahead

Industry insiders predict that 2026 will see continued expansion of active ETFs, AI-driven investment products, and bond ETFs, as investors diversify beyond equities.

“The ETF structure has proven its resilience through every kind of market,” said Bartolini. “It’s now the foundation of modern portfolio construction.”

The accelerating pace of inflows also underscores a broader shift in investor behavior toward self-directed and digital-first investing, amplified by fintech platforms and automated advisors that favor ETF-based portfolios.
