Crypto-ETFs recorded a record inflow of $2.6 billion: Bitcoin and Ethereum lead the way
American exchange-traded funds for Bitcoin and Ethereum demonstrated the strongest weekly capital inflow since October 2025. During the period from August 17 to 21, investors poured $2.6 billion into these instruments, signaling the return of confidence among institutional players in the crypto market.
The main flow of funds went into Bitcoin ETFs, which attracted $1.92 billion. Ethereum funds also showed an impressive result, receiving $697.18 million and fully offsetting the outflow of $391.96 million recorded the previous week.
Record inflow in 10 months
Bitcoin funds attracted capital for five consecutive trading days. The peak came on August 20, when $606 million flowed into ETFs in a single day — the highest figure since May. Trading activity also increased significantly: the volume of transactions in Bitcoin funds reached $22.15 billion over the week, nearly three times higher than the previous week's figures.
This momentum helped break a prolonged streak of outflows. The cumulative net inflow into Bitcoin ETFs peaked in October 2025 at $62.77 billion but then declined to $53.71 billion. The current week became an important step toward recovery.
Ethereum funds also posted their best result since October: on August 20, they attracted $220.77 million in a single day. At the same time, the total assets under management remain 53% below the record levels of August 2025. Since the start of the year, both types of ETFs are still in the red: investors withdrew $2.91 billion from Bitcoin funds and $177.93 million from Ethereum products.
Asset value growth exceeded fund inflows by 9 times
However, inflows alone do not explain the full picture. The assets of both categories increased in value by approximately $23 billion, while investments amounted to only $2.6 billion. The value of Bitcoin funds, excluding new contributions, rose by 22.9%, and Ethereum funds by 29.2%. Most of the rise occurred over three trading days from August 19 to 21.
The key driver was the revaluation of the coins themselves. At the time of publication, Bitcoin was trading around $76,230, and Ethereum at $2,406.
Altcoin ETFs continue to grow
Positive momentum also affected other crypto funds. The leader was the XRP ETF, which attracted $39.78 million with a record weekly trading volume of $271.74 million. Solana products secured second place with $28.34 million in inflows — this is already the eighth consecutive week of growth. Chainlink funds received $13.35 million, posting their second-best result since their launch in December 2025.
Hyperliquid ETFs attracted $3.89 million, and their total asset value reached a record $360.39 million. Dogecoin funds rounded out the list with a result of $654,416.
My view: the current inflow is not just a spike but a signal of a shift in sentiment among institutional investors. Asset value growth exceeding fund inflows by 9 times indicates that the market is driven not only by new money but also by a revaluation of the fair value of digital assets. If this momentum continues, we could see historical highs updated within the coming months.
