A Roundup of the Most Innovative ETFs Launched in May

For the second consecutive month, the industry saw a noticeable slowdown in new ETFs launched in May. However, even amid this more restrained launch period, the underlying trend of innovation continued to be a driving force within the ETF space.

May witnessed a subdued ETF launch environment. It saw only 52 new funds brought to market during the month. This marks the year's lowest monthly figure. That's a 29% drop from March, which saw the highest number of launches in 2025 to date.

ETF launches in May were overwhelmingly dominated by equity funds. Those accounted for 79% of all new offerings, a typical trend in the market. Notably, actively managed ETFs continued their upward trend. Those made up 87% of the new offerings, according to FactSet. Interest in active ETFs has been consistently strong for the past 18 months. That underscores the evolving landscape of the investment industry, where investors are increasingly seeking diverse strategies and innovative solutions to achieve their financial goals.

The overall launch numbers dipped in May. But the YTD figure of 370 ETF launches surpassed the previous year's 237 at the same point.

U.S. ETF assets under management saw a rise from $10.48 trillion to $11.05 trillion in May. And monthly inflows increased by 25% from April to $87.7 billion. Interestingly, flows into equity ETFs in May declined to its lowest level in 2025. Meanwhile, flows into fixed income ETFs tripled compared to April. They accounted for 44% of net new assets in May, per FactSet. YTD flows totaled $465 billion at the end of May. That potentially positioned the industry for another record-breaking year.
