US-listed ETFs attracted more than US$1 trillion in inflows during 1H26, the quickest time the industry has ever reached the impressive milestone. However, the rally was highly concentrated, with around 800 ETFs attracting little or no investor flows. To put these numbers into perspective, the US ETF industry has grown to ~US$19 trillion in AUM as of early 2026, with over 3,000 listed ETFs in the US market.
Monthly inflows in 2026 are running at roughly 2.5x the long-term historical pace, with inflows exceeding $100 billion for 13 consecutive months. Equity ETFs have dominated the 2026 YTD inflows; of the ~US$1.1 trillion in total positive ETF flows year-to-date through to yesterday, equity funds captured US$736 billion, or 67% of all inflows – it’s not surprising we’re in a bull market!
