BlackRock's massive buying, Fidelity's reverse selling: BTC ETF fund flows reveal institutional disagreements

U.S. Spot Bitcoin ETF Net Inflows Reach $100.2 Million Yesterday, Continuing Four Consecutive Days of Net Inflows. Behind These Seemingly Stable Numbers, There Is Clear Divergence Among Institutional Investors: BlackRock’s IBIT Attracted Over 3.1 Billion Yuan in a Single Day, While Fidelity’s FBTC Experienced Nearly 1.9 Billion Yuan in Outflows. This “Ice and Fire” Phenomenon Is Reshaping the Capital Map of the Crypto Market.

Growing Capital Divergence: Who Is Buying, Who Is Selling

According to the latest monitoring data, on January 15, the capital flows of U.S. spot Bitcoin ETFs showed significant institutional divergence:

This is not an isolated case. Looking at recent data, on January 14, U.S. Bitcoin spot ETF saw a single-day net inflow of $754 million, with Fidelity’s FBTC leading at $351 million (about 3,720 BTC), and BlackRock’s IBIT at $126 million. However, on January 15, the situation completely reversed—indicating significant attitude differences among institutional investors at different times.

Why Is BlackRock Continuing to Increase Its Holdings?

BlackRock’s IBIT has maintained large net inflows for several days, reflecting the world’s largest asset manager’s strong bullish stance on Bitcoin. From mid-January data, IBIT has become the strongest capital absorber among U.S. Bitcoin ETFs. The continuous buying by this giant institution is essentially a vote of confidence with real money—they believe the current price has investment value.

Fidelity’s “Counter-Operation” Is Worth Noting

Interestingly, Fidelity’s FBTC experienced net outflows on January 15, but this does not indicate a change in its overall attitude. Looking back to January 14, FBTC still led with a net inflow of $351 million. Such intraday fluctuations more likely reflect changes in investor structure—possibly short-term profit-taking or strategic adjustments. But from the cumulative net inflow perspective, FBTC remains the second-largest fund absorber after IBIT.

What Does Four Consecutive Days of Net Inflows Mean?

Four consecutive days of net inflows are uncommon in the crypto market. The significance of this phenomenon includes:

• Selling Pressure Has Eased: Grayscale GBTC, which experienced continuous large outflows since late last year, has gradually shifted to small outflows or stabilization, indicating the previous selling pressure has been largely released.
• Institutional Consensus Is Forming: Despite some ETFs showing divergence, the overall net inflow indicates increasing institutional demand for Bitcoin.
• Price Support Is Solid: Capital inflows often precede or coincide with price increases. Currently, BTC has fallen 1.05% in 24 hours but risen 4.69% over 7 days, indicating strong bottom support.

Comparing with Historical Data: How Strong Is This Influx?

According to reports, on January 14, the U.S. Bitcoin spot ETF saw a single-day net inflow of $754 million, a recent high. The cumulative inflow over the past four days is close to or exceeds the buildup period at the end of last year.

Grayscale mentioned in its report that December 2025 is a “Fake Winter,” with the market in a phase of shrinking volume and oscillation, but this is precisely a process of system energy accumulation. The continuous capital inflow starting mid-January reflects this “accumulation before rise.”

Personal Viewpoint

From an institutional behavior perspective, the current ETF capital flows indicate that the crypto market is transitioning from retail-driven sentiment to institutional pricing. The sustained increase by giants like BlackRock is more convincing than any market sentiment indicator—because their decisions are backed by rigorous risk assessment and long-term allocation considerations. Fidelity’s divergence adds short-term uncertainty but does not alter the overall net inflow trend.

Summary

The four-day consecutive net inflow of U.S. spot Bitcoin ETFs marks a new phase of sustained institutional capital entry. Despite divergence among major players like BlackRock and Fidelity in specific operations, the overall capital flow remains positive. This aligns with Grayscale’s “accumulation before rise” outlook, suggesting the market is preparing for the next upward move. The key going forward is whether this net inflow can continue and whether prices can break through current key resistance levels.
