The crypto ETF market continues to show impressive momentum: on August 27, spot bitcoin funds (BTC ETF) recorded inflows of $242.3 million, while their ether counterparts (ETH ETF) saw $235 million. Both sectors posted positive flows for the ninth consecutive day, pointing to sustained institutional optimism.
The synchrony of these moves deserves special attention. This is not about capital shifting from one asset to another, but rather a parallel buildup of positions. On August 24, BlackRock's iShares Bitcoin Trust (IBIT) attracted $209 million of the total $338 million that flowed into bitcoin ETFs. BlackRock's ether fund (ETHA) added $90.92 million that same day, out of $116 million in total inflows into Ethereum funds.
Against this backdrop, bitcoin traded near the $80,000 mark, posting a 2.12% gain over 24 hours, while Ethereum held around the $2,480 level. The total assets under management of all spot bitcoin ETFs reached $79.16 billion, with the sector's daily trading volume at $8.23 billion.
Institutional appetite extends beyond the two giants
Notably, inflows are also being recorded in other crypto funds. On August 27, spot Solana ETFs (SOL) received $60.91 million, while funds tracking Hyperliquid (HYPE) took in $24.42 million. Although the volumes are not yet comparable to bitcoin and Ethereum, the very fact of simultaneous growth signals an expansion of interest from major players beyond the two largest crypto assets.
This streak of inflows began on August 17 and continued uninterrupted through yesterday. Over the past week, institutional investors poured a combined $2.3 billion into bitcoin and Ethereum ETFs — the best result since October 2025. Regular purchases are reducing available supply on spot exchanges, which historically acts as a supportive factor for prices.
Analyst comment: Nine days of continuous inflows are not just statistics, but a signal that a sustainable trend is taking shape. The key question now is whether bitcoin and Ethereum can sustain their momentum into next week. If the streak continues, we could see an attempt to test new local highs, but at the first sign of a stumble, the market could correct, as some positions will have become overheated.
