Citigroup's Updated Outlook on ETF Growth
Assets under management for U.S. exchange-traded funds could more than double to $25 trillion by the end of this decade, according to Citigroup's latest analysis released on Thursday. Investors are flocking to ETFs for their low-cost, diversified exposure across various markets, driving this projected expansion. As of March 2025, the U.S.-listed ETF industry's total assets were approximately $10.4 trillion, providing a solid baseline for future growth.
The Wall Street brokerage had earlier projected ETF AUM to reach $19 trillion by 2030 and $29 trillion by 2035. Citigroup has now revised these figures upward, anticipating more than $40 trillion by 2035. This optimistic outlook reflects maturing market dynamics where ETF growth enters a more balanced phase.
Balancing Flows and Performance in ETF Expansion
While these projections are more bullish than prior estimates, they indicate ETFs will experience a more mature stage of AUM growth. Organic drivers like investor flows and inorganic factors such as performance returns will balance out more evenly compared to the disproportionate flow dominance of the past ten years, Citigroup noted.
A significant portion of this growth is expected from active ETFs, which are forecasted to outpace their passive counterparts in attracting investments. Active ETFs represent one of the fastest-growing segments in the ETF market, appealing to investors through flexible strategies and competitive costs. Unlike passive ETFs that simply track and mirror an index's performance, active ones aim to outperform benchmarks or achieve targeted investment outcomes.
Active ETFs Poised for Market Share Doubling
In its base case, Citigroup expects active ETFs' market share of total ETF AUM to double over the next ten years. This shift stems from active products capturing a larger portion of industry flows. The brokerage highlighted this trend in a note issued Thursday, underscoring the evolving preferences in the investment landscape.
Several factors are bolstering this industry-wide growth. Product innovation continues to introduce new offerings tailored to investor needs. Regulatory changes have simplified ETF launches, lowering barriers to entry. Investors are increasingly adopting sophisticated strategies, and demand persists for flexible, tax-efficient investment solutions that ETFs provide effectively.
Key Drivers of ETF Industry Momentum
- Product innovation expanding ETF variety and appeal.
- Easier regulatory environment for launching new funds.
- Shift toward sophisticated investment strategies.
- Rising demand for tax-efficient, adaptable solutions.
- Balanced growth from both flows and market performance.
- Rapid expansion in active ETF segment outpacing passive.
Record Inflows Underscore ETF Popularity
Recent data reinforces Citigroup's projections. ETFs tracking U.S. equities have recorded more than $75.8 billion in inflows so far this year, building on over $1.1 trillion in inflows from the last two years, per LSEG Lipper data. Overall, U.S.-domiciled ETFs have seen more than $435 billion in inflows year-to-date.
These figures highlight the relentless investor appetite for ETFs amid broader market trends. Acquisitions like Goldman Sachs' purchase of Innovator Capital, which lifted its ETF assets to $90 billion, and strategic moves such as Vanguard stripping China from emerging markets plays, illustrate the dynamic environment shaping the sector. Citigroup's analysis positions ETFs as a cornerstone of modern portfolio construction, with growth trajectories pointing to substantial scale in the coming years.
