Beyond SPY: Active ETFs Poised To Lead Next Phase Of $25 Trillion Industry Boom

The U.S. ETF industry is on track for another decade of explosive growth, but the next leg of expansion may look very different from the last. Reuters reported that according to Citigroup, ETF assets under management could more than double from roughly $10.4 trillion in March 2025 to $25 trillion by 2030, with projections now topping $40 trillion by 2035.

While passive index-tracking funds powered the first wave of ETF adoption, Citi expects active ETFs to take center stage going forward. The brokerage projects that active strategies will double their share of total ETF assets over the next decade, fueled by rising investor demand for flexibility, income generation, and downside protection in an increasingly volatile market.

Active ETFs Gain Ground As Investors Seek Flexibility

Active ETFs, once a niche corner of the market, are rapidly gaining traction as investors look beyond traditional index exposure. Unlike passive funds that mirror benchmarks, active ETFs aim to outperform or deliver specific outcomes through security selection, derivatives, or tactical allocation.

This shift comes as investors grow more conscious of market concentration risks, particularly in mega-cap-heavy indexes. Active strategies offer a way to navigate these risks while still benefiting from the ETF wrapper's lower costs and tax efficiency compared to mutual funds.

Citi notes that growth in ETF assets will increasingly be driven by a balance between organic inflows and market performance, marking a transition from the hypergrowth phase of the past decade to a more mature yet expanding market structure.

Where The Flows Are Going

Active ETF standouts:

• ARK Innovation ETF (BATS:ARKK)— A flagship actively managed fund focused on disruptive innovation, known for its high-conviction bets. The fund gained more than 4% in the past week.
• JPMorgan Equity Premium Income ETF (NYSE:JEPI)— A fast-growing income-focused ETF using options strategies to generate yield. The fund pulled in inflows of $1.4 billion in March, according to Etf Database. Over the past five days, the ETF gained 2%.
• Dimensional U.S. Core Equity 2 ETF (NYSE:DFAC)— Combines active tilts with systematic, factor-based investing. The fund saw inflows of almost $345 million in March, and the fund price has gained more than 3% in the past week.

Recent flow pressure on passive leaders:

• SPDR S&P 500 ETF Trust (NYSE:SPY)— Saw more than $10 billion in outflows in March, signaling a pause in broad-based index exposure.
• Invesco QQQ Trust (NASDAQ:QQQ)— Recorded roughly $3 billion in outflows during the same period amid tech-sector volatility.

The pullback highlights a shifting investor mindset, as some market participants rotate away from cap-weighted benchmarks toward more selective, strategy-driven exposures. While passive ETFs continue to dominate in overall assets, active ETFs are among the fastest-growing segments, attracting a rising share of the more than $435 billion in inflows into U.S.-domiciled ETFs so far this year, according to LSEG Lipper.

With product innovation accelerating and regulatory barriers easing, the ETF industry's next chapter may become smarter, more targeted, and increasingly active.
