American spot exchange-traded funds for Bitcoin and Ethereum recorded their strongest weekly capital inflow since October 2025. From August 17 to 21, investors poured $2.6 billion into these instruments, signaling the return of institutional risk appetite after a prolonged correction.
Bitcoin ETFs became the main beneficiary of this surge, attracting $1.92 billion. Ethereum funds also showed solid momentum: inflows totaled $697.18 million, fully offsetting the $391.96 million outflow recorded the previous week. This marks the first significant reversal for Ethereum products in recent months.
Record volumes and recovery after the downturn
Bitcoin funds posted positive flows for five consecutive trading days. The peak came on August 20, when $606 million flowed into BTC ETFs in a single day—the strongest result since May. Trading activity also surged sharply: weekly trading volume reached $22.15 billion, nearly three times the figures from the previous week.
This momentum broke a prolonged phase of outflows. The cumulative net inflow into Bitcoin funds, which peaked in October 2025 at $62.77 billion, has now declined to $53.71 billion. However, the current surge may signal the start of a new accumulation cycle.
Ethereum funds also posted their best result since October: on August 20, they attracted $220.77 million in a single day. Nevertheless, the total assets under management for these products remain 53% below the record levels of August 2025, indicating significant room for further recovery.
Asset growth outpaced inflows by 9 times
Notably, inflows alone do not explain this picture. The total value of assets in both categories rose by approximately $23 billion, while investors contributed only $2.6 billion. Excluding new contributions, the value of Bitcoin funds increased by 22.9%, and Ethereum products by 29.2%. The main driver is the revaluation of the coins themselves: at the time of analysis, Bitcoin was trading around $76,230, and Ethereum at $2,406.
Altcoin ETFs: a new wave of interest
Demand was not limited to flagship assets. Altcoin funds also recorded net inflows. XRP ETFs led the way with $39.78 million and a record weekly trading volume of $271.74 million. Solana products secured second place with $28.34 million—marking the eighth consecutive week of positive momentum.
Chainlink funds attracted $13.35 million, posting their second-best result since their launch in December 2025. Hyperliquid (HYPE) ETFs received $3.89 million, with their total assets under management reaching a record $360.39 million. Dogecoin funds rounded out the list with inflows of $654,416.
My comment: The current momentum confirms that institutional investors view the recent correction as an entry opportunity rather than a signal to exit. Particularly telling is the growth in asset value without significant new capital injections—this suggests the market is being driven by revaluation rather than speculative capital. However, for a sustainable trend, inflows need to persist at current levels for several more weeks.
