Crypto-ETFs recorded a record inflow: $2.6 billion in a week — the highest since October
American exchange-traded funds for Bitcoin and Ethereum have demonstrated the strongest weekly capital inflow in the last ten months. From August 17 to 21, total inflows into these instruments reached $2.6 billion—the best result since October 2025. The market has clearly shifted into an active accumulation phase, and investors are once again showing an appetite for risk.
Bitcoin ETFs lead, Ethereum catches up
The bulk of the inflow went to Bitcoin funds, which attracted $1.92 billion. Notably, inflows were recorded for five consecutive trading days, with the peak on August 20, when $606 million flowed into BTC ETFs in a single day. This is the highest one-day figure since May of this year.
Ethereum funds also showed impressive momentum, attracting $697.18 million. This fully offset the outflow of $391.96 million recorded the previous week. The best day for ETH ETFs came on August 20—$220.77 million, marking a record since October.
Trading activity hits records
Alongside inflows, trading volumes also rose. Over the week, Bitcoin ETFs generated trades worth $22.15 billion—nearly three times more than in the previous seven days. This signals the return of institutional players who are not just holding positions but actively expanding them.
The cumulative net inflow into BTC funds peaked in October 2025 at $62.77 billion but has since declined to $53.71 billion. Despite this, current dynamics indicate a restoration of confidence after a period of correction.
Altcoin ETFs also in positive territory
Demand was not limited to leading coins. XRP ETFs became leaders among altcoins with an inflow of $39.78 million and a record weekly trading volume of $271.74 million. Solana funds secured second place with $28.34 million—this marks the eighth consecutive week of positive momentum.
Chainlink products attracted $13.35 million, posting the second-best result since their launch in December 2025. Hyperliquid ETFs received $3.89 million, with their total assets growing to a record $360.39 million. Dogecoin funds round out the list with a symbolic $654,416.
It is especially telling that the rise in asset value outpaced new investments by nine times. Excluding inflows, the market capitalization of Bitcoin funds grew by 22.9%, and Ethereum by 29.2%. Most of the uptick occurred over three trading days from August 19 to 21. At the time of analysis, Bitcoin was trading around $76,230, and Ethereum at $2,406.
My take: Current dynamics confirm that institutional interest in digital assets has not just recovered but is on the rise. However, it is worth remembering: a significant portion of the growth is driven by the revaluation of the coins themselves, not new capital. If the price corrects, inflows could quickly turn into outflows. For now, the market is showing a healthy appetite for risk, and this is a positive signal for the medium-term outlook.
