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, IBIT is the only ETF on the 2025 Flow Leaderboard with a negative year-to-date return (YTD), highlighting it as an outlier on performance versus peers (source: @EricBalchunas on X, Dec 19, 2025). He reports that despite the negative return, IBIT still placed 6th by net inflows for the year, underscoring strong investor demand (source: @EricBalchunas on X, Dec 19, 2025). He adds that IBIT attracted more money than GLD in 2025 flows, indicating robust allocation to spot Bitcoin exposure via ETFs (source: @EricBalchunas on X, Dec 19, 2025). Balchunas characterizes this pattern as HODL-style behavior from traditional investors, which he presents as the key takeaway for BTC-linked ETF flows (source: @EricBalchunas on X, Dec 19, 2025).

According to Farside Investors, US-listed Bitcoin ETFs recorded a total net inflow of $607.1 million on May 21, 2025, marking a significant surge in institutional demand. The iShares Bitcoin Trust (IBIT) led with $530.6 million, followed by Fidelity's FBTC at $23.5 million and Bitwise's BITB at $20.5 million. Other funds such as ARKB and HODL saw modest inflows, while several products like BTCO, EZBC, BRRR, BTCW, and GBTC reported zero flows. This robust ETF inflow is a bullish signal for crypto traders, indicating heightened market confidence and likely supporting upward price momentum in the near term (source: Farside Investors, Twitter, May 22, 2025).

According to Farside Investors, Bitcoin ETF net inflow reached $674.9 million on May 2, 2025, with BlackRock's IBIT ETF accounting for the entire inflow and all other major ETFs, including FBTC, BITB, ARKB, and GBTC, recording zero net flows. This concentrated inflow into IBIT indicates strong institutional buying demand for this specific fund, suggesting a potential bullish sentiment for Bitcoin price action in the short term (source: Farside Investors on Twitter). Traders may interpret this as a sign of market confidence focused on the IBIT product, which could influence Bitcoin spot and futures trading strategies.
