According to Woofun AI, between July 27th and 31st, the US spot cryptocurrency ETF market showed significant institutional fragmentation, and investor behavior was more reflected in the adjustment of positions between assets rather than complete withdrawal. Crypto Patel's data analysis revealed this core contradiction: despite the overall financial pressure on the market, there is a sharp divergence in demand trends for different mainstream digital assets, and institutions are redefining their digital asset allocation weights.
Looking at overall capital flows, US spot cryptocurrency ETFs recorded a net outflow of about $30.72 million last week. However, this macro data conceals the extreme contrast between leading assets. Bitcoin ETFs became the hardest hit area of capital withdrawals this week. The net outflow reached 61.53 million US dollars, equivalent to about 915 BTC leaving the fund portfolio. This amount is almost equivalent to the total amount of newly mined bitcoins in two days.
Despite the significant decline, the total asset size of ETFs is still limited, which is more reflective of the fine-tuning of the investment portfolio. In stark contrast to this, spot Ethereum ETFs attracted about $27.42 million in new capital inflows, corresponding to about 5230 ETH entering institutional products. At the counterparty level, BlackRock (BLK.US) was the biggest buyer this week. Its ETF bought around 1,395 BTC and 30,179 ETH; Fidelity adopted the opposite strategy, selling around 1,321 BTC and 10,890 ETH.
Additionally, Bitwise's ETF also bought around 49 BTC. Woofun AI collated data and showed that this long and short game is not simply one-sided bearishness, but rather a structural rotation of leading institutions over specific assets.
The focus has turned to second-tier assets, and the details of the institution's long and short game have further enriched the market picture. Ripple's related products performed strongly, recording a net inflow of approximately $14.86 million, making it one of the top performing cryptocurrency investment products this week. Solana's spot ETF also received about $2.82 million in new capital investment, while HBAR related products brought in nearly $461,390 in capital inflows, increasing the level of fund diversification.
However, not all products benefited, and the HYPE ETF saw a net outflow of approximately $14.75 million. At the institutional level, Grayscale reduced its holdings by selling 696 BTC and 11,146 ETH, ARK sold about 475 BTC and 1248 ETH, and 21Shares also cut its holdings.
Meanwhile, Morgan Stanley (MS.US) bought around 116 BTC, increasing its share of investment in some digital assets. Notably, ETFs for assets such as Binance Coin, Avalanche, Boca, Dogecoin, Chainlink, and Litecoin saw no capital flows this week, indicating that institutional activity is still highly concentrated on the largest mature products.
Broader ETF market data reflects investors' continued preference for diversified investment funds. In the field of traditional assets, Pioneer's VOO (VOO.US) is still the product with the largest net inflow since this year, showing a delicate balance between traditional assets and digital asset allocation. Overall, this week's data confirms the ongoing process of rebalancing institutional capital between traditional and digital markets. Bitcoin, Ethereum, and Ripple remain core assets in investment activities due to their liquidity and institutional recognition.
This trend of differentiation shows that as the market matures, institutions are shifting from a general upward logic to a selective strategy based on fundamentals and liquidity, and performance differences between assets may increase further in the future.
