American spot exchange-traded funds for Bitcoin and Ethereum experienced their strongest capital inflow in the last ten months. During the trading week from August 17 to 21, $2.6 billion flowed into these instruments — the best figure since October 2025. This is a signal that cannot be ignored: institutional players are once again actively increasing their exposure to digital assets.
Bitcoin Funds Lead, Ethereum Recovers
The main impact was borne by Bitcoin ETFs, which attracted $1.92 billion. Notably, inflows were recorded for five consecutive trading days, with the peak occurring on August 20, when $606 million flowed into the funds in a single day. Trading volumes are also impressive: over the week, the total turnover of Bitcoin funds reached $22.15 billion — nearly three times more than the previous week.
Ethereum funds, in turn, showed a confident recovery, attracting $697.18 million and fully offsetting the outflow of $391.96 million recorded the previous week. They delivered their best result on August 20 — $220.77 million in one day, marking the highest figure since October.
Asset Growth Exceeded Fund Inflows by 9 Times
It is important to understand: inflows are only part of the picture. The total value of assets under management for both categories of funds grew by approximately $23 billion, while investors contributed only $2.6 billion. This means the main driver was the appreciation of the coins themselves. Excluding new contributions, the value of Bitcoin funds increased by 22.9%, and Ethereum funds by 29.2%. At the time of publication, Bitcoin is trading around $76,230, and Ethereum is in the region of $2,406.
Since the start of the year, both segments remain in negative territory in terms of net flows: $2.91 billion has been withdrawn from Bitcoin ETFs, and $177.93 million from Ethereum products. However, the last week demonstrates a clear shift in sentiment.
Altcoin ETFs: A New Wave of Interest
Altcoins have not been left behind either. The leader among them was the XRP ETF with an inflow of $39.78 million and a record weekly trading volume of $271.74 million. Solana funds attracted $28.34 million — this is already the eighth consecutive week with a positive result. Chainlink funds received $13.35 million, marking the second-best figure since their launch in December 2025.
Hyperliquid products gathered $3.89 million, bringing the total value of assets to a record $360.39 million. Closing the list are Dogecoin funds with a result of $654,416.
My take: The current dynamics indicate a return of risk appetite among institutions, but one should not be deceived — a significant portion of the growth is driven by market revaluation rather than new capital. The sustainability of this trend will be tested in the coming weeks, especially against the backdrop of macroeconomic uncertainty. For now, the market is receiving a powerful positive signal capable of supporting the upward movement.
