The capital flow of the US spot Bitcoin ETF can be summarized as: an overall strong trend, but with increased daily volatility and disagreements among institutions.

📈 Recent Capital Inflow Overview

Overall performance: In the week ending April 11, the US spot Bitcoin ETF achieved approximately $1.1 billion in net inflows, marking the best weekly performance since January of this year. This brings the total net inflow since the beginning of the year to over $56 billion.

Daily divergence: Despite the strong weekly data, there were days of capital outflows. For example, on April 13 (Eastern Time), all spot Bitcoin ETFs combined had a net outflow of about $291 million, indicating that some funds took profits when the market rebounded to high levels.

🏛️ Analysis of Core Institutional Buyers

The current market capital flows are mainly dominated by the following institutions, whose behaviors show clear differences:

BlackRock

Product: iShares Bitcoin Trust (IBIT)

Role: The most steadfast bull and "stabilizer." On April 13, when the market overall experienced outflows, IBIT was the only major product still showing a net inflow (about $34.7 million), demonstrating strong support capacity and long-term allocation commitment. Its cumulative net inflow has exceeded $63 billion, making it the market's absolute leader.

Fidelity

Product: Fidelity Wise Origin Bitcoin Fund (FBTC)

Role: From bullish to profit-taking. During the rally from April 7-10, FBTC was an important buying force. But on April 13, it became the largest outflow, with a single-day net outflow of about $229 million. This indicates that some short-term funds or investors chose to exit at the high point of the rebound, showing more flexibility and volatility than BlackRock.

Grayscale

Product: Grayscale Bitcoin Trust (GBTC)

Role: From "selling pressure source" to "stability pool." During the initial ETF approval phase, GBTC experienced continuous large outflows due to fund migration. Currently, its fund activity has stabilized, with relatively small daily flows, no longer posing a major drag on the market.

Other institutions (such as Ark Invest, Bitwise, etc.)

Role: Trend followers. These smaller ETF products' capital flows tend to be highly synchronized with overall market sentiment, with net inflows on rising days and outflows during corrections, serving as auxiliary indicators of market sentiment.

⚡ Key Insights

Institutional turnover: Recent capital flows indicate that there has been a transfer of funds among institutions (from Fidelity to BlackRock), rather than pure market withdrawal. This reflects differing judgments among institutional investors regarding short-term prices and long-term strategies.

Market health warning: Caution is needed regarding divergence between price increases and ETF capital inflows (such as on April 13). If Bitcoin prices continue to rise without support from new ETF funds, the basis for this rebound will weaken, increasing the risk of a correction.

In summary, the buying of Bitcoin ETFs is the core engine of this bull market, but the internal dynamics (among different institutions) are subtly changing. BlackRock remains the most stable cornerstone, while Fidelity's volatility represents short-term market sentiment. Future developments should closely monitor the capital flow comparison between these two giants.
