According to @EricBalchunas, passive funds gained 1.4 percentage points of market share in 2025 to reach 54% overall, comprising roughly 60% on the equity side and 40% on the fixed-income side, source: @EricBalchunas on X, Jan 8, 2026. According to @EricBalchunas citing analysis by @JSeyff, the slower pace of passive share gains was driven by a bull market subsidy and genuine growth from active strategies, particularly in active ETFs, fixed income, and buffer strategies, source: @EricBalchunas on X, Jan 8, 2026; analysis referenced from @JSeyff.

According to Eric Balchunas, only 50% of 2025 ETF net inflows went into funds charging 10 bps or less, the lowest share in years, source: Eric Balchunas Jan 7 2026. He said this is not due to investors leaving ultra cheap funds, since the 50% slice still totaled about 750 billion dollars of flows, source: Eric Balchunas Jan 7 2026. He attributed the shift to an expanding ETF universe that includes legacy active strategies, buffer ETFs, hot sauce products, and BYOA, source: Eric Balchunas Jan 7 2026. He added that this is welcome news for asset managers after a period when cheap beta seemed poised to take everything, source: Eric Balchunas Jan 7 2026.

According to @EricBalchunas, active ETFs now outnumber passive ETFs by fund count, while active strategies hold roughly 10% of total ETF assets and are growing quickly (source: Eric Balchunas on X, Oct 14, 2025). For traders, this shift in product mix highlights that new launches and flows may increasingly favor active vehicles even as passive AUM dominance persists, affecting liquidity dispersion and pricing across segments (source: Eric Balchunas on X, Oct 14, 2025). In crypto specifically, most U.S. spot Bitcoin ETFs such as IBIT and FBTC are passively managed index trackers per their SEC prospectuses, making the broader active-ETF growth an important backdrop when assessing future crypto ETF structures, fees, and tracking approaches (source: SEC prospectuses for iShares Bitcoin Trust and Fidelity Wise Origin Bitcoin Fund, Jan 2024). Monitor the active-to-passive ETF launch ratio and net inflows as leading indicators for potential demand shifts that could influence digital-asset exposure via ETFs (source: Eric Balchunas on X, Oct 14, 2025).

According to Eric Balchunas, active ETFs have attracted 40% of net flows in 2025 despite comprising just 10% of total ETF assets. Additionally, nearly 90% of all new ETF launches this year are active, enabling active ETFs to surpass passive ETFs in terms of total launches. This significant capital inflow and surge in active ETF launches suggest a shift in investor preference toward active strategies, which could impact liquidity and volatility in related sectors, including cryptocurrency-linked ETFs. Traders should monitor this trend, as increased active management may lead to more dynamic portfolio adjustments and could influence market correlations with crypto assets (Source: Eric Balchunas on Twitter, June 12, 2025).

According to @SirYappityyapp, ETF launches in April 2025 increased by 132% year-over-year, marking record monthly growth for the third consecutive month. The market is now 50% ahead of last year's record pace and could see up to 1,000 ETF launches this year. Notably, 88% of new ETFs are actively managed and 68% incorporate derivatives, indicating heightened risk appetite and innovation in investment products. For crypto traders, this surge in ETF activity, especially those using derivatives, signals increased institutional interest in alternative assets, potentially boosting liquidity and volatility in related crypto markets (Source: Eric Balchunas via Twitter, May 9, 2025).
