Bitcoin retraced 25%, with IBIT capital inflow of $8.4 billion: Why are institutions continuing to buy ETFs?

The cryptocurrency market in the first quarter of 2026 was anything but calm. Bitcoin steadily declined from about $87,000 at the beginning of January to roughly $66,000 by the end of March, a quarterly drop of over 25%, marking the worst quarterly performance since 2018. Market sentiment cooled again, with voices echoing that “the bear market has arrived.”

However, during the same period of continuous price decline, a set of fund flow data showed an entirely opposite signal. The iShares Bitcoin Trust Fund under the global asset management giant BlackRock attracted net capital inflows throughout the quarter, recording net inflows on 48 out of 62 trading days, with a total net inflow of approximately $8.4 billion for the entire quarter. The underlying issues behind this data go far deeper than “whether institutions are optimistic about Bitcoin”—they reveal that institutional investors have already formed an independent, systematic decision-making framework for crypto asset allocation.

An “Counterintuitive” Quarterly Report

On April 14, 2026, BlackRock released its first-quarter financial report. Data showed that the company’s GAAP net profit for the quarter reached $2.2 billion, up 17% year-over-year, with total revenue of about $6.7 billion, up 27% year-over-year. The platform recorded approximately $130 billion in net inflows, with the iShares ETF product lineup contributing about $132 billion, setting a new quarterly record.

In the crypto asset sector, IBIT saw a net inflow of about $8.4 billion in the quarter. By the end of the quarter, IBIT managed assets of approximately $55 billion, holding over 800k Bitcoin, about 3.8% of the total Bitcoin supply of 21 million. The fund held about 49% of the total assets of the U.S. spot Bitcoin ETFs, leading ahead of Fidelity’s FBTC and Grayscale’s GBTC.

According to Gate data, as of April 27, 2026, Bitcoin’s price was $77,688.2, down about 0.3% in 24 hours, with a market cap of $1.49 trillion and a market share of 56.37%.

Price Pressure Under Macro Headwinds

To understand the significance of IBIT’s fund flow in the first quarter, we first need to revisit the macro environment at that time.

In early 2026, global risk assets faced multiple pressures. Geopolitically, rising tensions in the Middle East pushed Brent crude oil prices above $116 per barrel, fueling inflation expectations. The bond market responded swiftly, with expectations of Federal Reserve rate cuts in 2026 sharply declining, and federal funds rate futures once showed a nearly 30% chance of rate hikes before year-end. The strengthening dollar and rising 10-year U.S. Treasury yields to 4.40% jointly drained global liquidity.

On the policy front, the Fed’s hawkish turn became a core variable suppressing risk asset prices. As a non-yielding asset, Bitcoin was especially under pressure in a high-interest-rate environment.

Within the crypto industry, regulatory frameworks were also undergoing profound changes. In September 2025, the U.S. Securities and Exchange Commission introduced a new general listing rule for ETFs, reducing approval cycles from 240 days to 75 days. On March 17, 2026, the SEC and the Commodity Futures Trading Commission jointly declared staking rewards as non-securities, initiating a wave of staking ETF issuances. While these regulatory developments were beneficial for institutional entry in the long term, they did not offset the macro pressures impacting prices in the short term.

Key Event Timeline:

Data and Structural Analysis: A Three-Dimensional Perspective on IBIT Fund Flows

Dimension 1: Continuity and Density of IBIT Inflows

In the first quarter, IBIT experienced net inflows on 48 out of 62 trading days, meaning approximately 77% of trading days saw net inflows, totaling about $8.4 billion. This ratio is especially notable in a market environment where prices declined over 25%. During a week in mid-March (March 9–13), the U.S. spot Bitcoin ETF recorded a total net inflow of $767 million, with IBIT alone contributing about $600 million.

After April, this trend further intensified. IBIT achieved nine consecutive days of net inflows, accumulating approximately 21,500 BTC holdings during this period, with total holdings surpassing 800,000 BTC for the first time, reaching 806,700 BTC, with a market value of about $14.9k, setting a new record for the fund’s holdings. On April 15, the net inflow reached $291.9 million, and on April 10, $269.3 million.

Dimension 2: Asset Under Management (AUM) Shrinkage and Net Inflows Coexist

A potentially misleading data point is the change in IBIT’s AUM. Due to Bitcoin’s price decline, IBIT’s AUM shrank from about $78 billion at the start of the quarter to roughly $54 billion at the end. This means that despite continuous net inflows, the market value shrank by about $24 billion, far exceeding the net inflow amount. This phenomenon confirms a core judgment: the shrinkage in AUM is driven by price declines, not redemption pressure. In other words, investors did not withdraw due to falling prices; instead, they continued to buy more.

Dimension 3: Structural Differentiation in Institutional Behavior

Institutional behavior was not uniform in the first quarter. Hedge fund Brevan Howard reduced its IBIT holdings by 85%, while corporate treasuries, university endowments, ETF issuers, and Abu Dhabi’s Mubadala increased their holdings. As of late April, Strategy had accumulated over $10 billion worth of Bitcoin, holding 815,061 BTC, surpassing IBIT to become the world’s largest corporate Bitcoin holder.

This divergence itself signals important behavioral insights: short-term trading-driven funds (like some hedge funds) are choosing to exit, while allocation-driven funds (like sovereign funds and corporate treasuries) are increasing their positions. The operational approaches and decision timelines of these two types of funds are markedly different, jointly shaping the buy-side ecosystem of the quarter.

Public Sentiment and Divergent Views

Regarding IBIT’s quarterly data and institutional behavior, three typical interpretive perspectives have emerged.

One camp believes that IBIT’s sustained net inflows during a price decline have profound market implications. A widely cited view is that: this “does not indicate confidence in short-term prices but shows that a significant proportion of institutional and wealth management funds have made allocation decisions, and these decisions have become durable—advisors who allocated in 2024 have never redeemed during downturns.”

Another camp sees the decline as a normal correction within a bull cycle. Experts like the head of research at Galaxy Digital suggest that the long-term logic remains intact. The behavior of pushing holdings to record highs is interpreted as a vote of confidence in Bitcoin’s long-term value.

A cautious and observant camp points out that the fund flow into spot ETFs reversed at the end of the quarter, with some inflows attributed to quarter-end rebalancing and dividend purchases rather than fundamental shifts in institutional conviction. On March 27, IBIT recorded a single-day outflow of $201 million, indicating volatility in institutional participation. Extreme bearish analysts like Bloomberg senior strategist Mike McGlone even reiterated warnings of a potential sharp decline in Bitcoin.

The commonality among these perspectives is that all acknowledge ongoing institutional inflows. The disagreement lies in the motivation and sustainability of these inflows. This article leans toward the view that the “structural allocation” explanation is most supported by the data—the consistent behavior of IBIT on 48 net inflow days is hard to explain solely by short-term speculation or rebalancing. The factual basis for this judgment includes: first, the high proportion of net inflow days at 77%, exceeding the entire quarter; second, the steady inflow during price declines rather than during rebounds; third, the acceleration of inflows after April.

Industry Impact Analysis: Structural Reconfiguration of Institutional Allocation

The deep impact of IBIT’s first-quarter data on the industry can be viewed from three levels.

First level: Consolidation of ETF market competition. As of March 30, 2026, U.S. listed spot Bitcoin ETFs held about 1.29 million BTC, worth roughly $86.9 billion. IBIT’s single product accounted for about 60% of the market share, forming a clear leading barrier. New entrants like Morgan Stanley’s MSBT, with an initial fee of 0.14% and a launch size of $133 million after 8 days, face significant competitive challenges from IBIT’s established position. With 26 months of first-mover advantage, institutional Bitcoin allocation decisions are embedded in thousands of client portfolios.

Second level: Establishment of a paradigm for institutional allocation behavior. The continuous inflows into IBIT indicate that some institutional investors have crossed the decision threshold of “whether to allocate Bitcoin” and entered the stage of “managing allocation ratios.” This shift has profound implications—it means that future Bitcoin market buyers will include a rigid allocation layer unaffected by short-term price fluctuations.

Third level: Emergence of passive-style allocation behavior. As ETF products mature, some funds may adopt dollar-cost averaging or other automated entry methods, forming a near “passive allocation” pattern. This phenomenon has long existed in traditional asset classes but is relatively new in the crypto market.

Conclusion

In the narrative of the crypto market, “institutional entry” has been a recurring theme for nearly a decade. But the IBIT data from Q1 2026 provides more verifiable evidence: institutions are not only in the market but are participating in a manner distinct from retail investors—buying more during declines, holding through volatility, and maintaining allocations amid macro headwinds.

The fact that IBIT experienced 48 net inflow days despite a decline of over 25% in price does not itself indicate a directional judgment on short-term prices. But it points to a more structural trend: Bitcoin as an asset class is gaining a relatively stable allocation position within some institutional portfolios. While this position may be modest (less than 0.5% of traditional AUM), its existence has quietly shifted the discussion from “whether to allocate” to “how much to allocate.”
