TLDR
- BlackRock’s IBIT pulled in about $25B in 2025 inflows, ranking sixth among U.S. ETFs.
- IBIT is the only top-ranked ETF in 2025 with a negative year-to-date return.
- Gold ETF GLD gained over 60% in 2025 but attracted less capital than IBIT.
- BlackRock reported $2.34B in IBIT outflows during November 2025.
BlackRock’s spot Bitcoin ETF, iShares Bitcoin Trust (IBIT), ranked sixth among all U.S. ETFs for net inflows in 2025. This result comes despite the fund recording a negative annual return. Data from Bloomberg indicates that IBIT attracted approximately $25 billion in inflows year-to-date. The ranking places IBIT ahead of several top-performing funds, indicating strong investor interest in Bitcoin exposure, regardless of short-term price fluctuations.
Strong ETF Inflows Signal Institutional Interest in Bitcoin
IBIT’s inflow of $25 billion this year places it among the most successful ETFs in terms of capital attraction. Notably, it ranks above several equity and bond ETFs that posted double-digit gains, as well as the gold-backed GLD ETF, which recorded over 60% gains but drew less investment than IBIT.
Despite a -9.6% return in 2025, BlackRock’s IBIT just ranked 6th in total ETF inflows ($25B+).

Bloomberg ETF analyst Eric Balchunas highlighted these numbers to illustrate investor behavior. He stated that such inflows, despite negative returns, reflect longer-term confidence in Bitcoin as an asset class. He suggested that many investors are not focused on short-term gains but instead take a long-term strategy, with some applying a “buy and hold” approach. Balchunas described this pattern as consistent with the behavior of seasoned investors who view Bitcoin as a long-term store of value or strategic asset.
Bitcoin Price Movement Lags Behind ETF Demand
Despite continued capital inflow into spot Bitcoin ETFs, Bitcoin’s market performance in 2025 has not kept pace. On a year-to-date basis, Bitcoin has underperformed, with prices declining from prior highs. Some market participants have questioned why rising institutional ETF purchases have not driven stronger price performance.
Balchunas addressed this concern by noting that the Bitcoin market has matured. In this environment, long-term holders often choose to manage risk and take profits rather than chase short-term price movements. Additionally, many are now using options strategies to generate yield, reducing immediate upward pressure on prices.
Data from December 19 showed $158 million in net outflows across all U.S. spot Bitcoin ETFs. Fidelity’s FBTC was the only fund to report net inflows that day. Spot Ether ETFs also experienced continued outflows, with $75.9 million withdrawn, extending a seven-day losing streak for Ether-based ETFs.
BlackRock Maintains Confidence Despite Short-Term Outflows
In November 2025, BlackRock’s IBIT faced nearly $2.34 billion in net outflows, including two days of large investor withdrawals. While the short-term trend raised concerns among some observers, BlackRock remained confident in its long-term strategy.

Speaking at Blockchain Conference 2025 in São Paulo, Cristiano Castro, BlackRock’s director of business development, emphasized that the firm’s Bitcoin ETF products have become major contributors to revenue. He noted that ETFs serve multiple roles, including cash-flow management and rebalancing, and that periods of outflows are part of regular capital market cycles.
