Bitcoin ETF inflows reached $242.30 million on August 27. This extended their streak to nine consecutive trading days.
Spot Ethereum ETFs matched the pace. The category added $235 million on the same day. This marked its own ninth straight inflow session.
Why Bitcoin ETF inflows matter
The parallel streaks follow heavy institutional buying. BlackRock’s iShares Bitcoin Trust contributed $209 million on August 24. This was part of a $338 million Bitcoin ETF inflow. Its Ethereum fund, ETHA, added $90.92 million of that day’s $116 million haul.
Bitcoin traded near $80,000 on Thursday. It is up 2.12% over 24 hours. Ether changed hands near $2,480 over the same period.
Total net assets across spot Bitcoin ETFs stood at $79.16 billion. Trading volume across the category reached $8.23 billion. CoinGlass data confirms these figures.
The two categories posted their biggest combined week since October last week. They drew $2.3 billion between them. This suggests institutions are building positions across both assets. They are not rotating between them.
Nine-day streak extends
The current streak traces back to August 17. Both categories began a run that reached four days by August 20. It has continued uninterrupted through August 27.
Smaller crypto funds joined the advance. Spot Solana ETFs added $60.91 million. Spot Hyperliquid ETFs drew $24.42 million. Both occurred on August 27.
Both smaller funds remain far behind Bitcoin and Ether in scale. Nevertheless, the same-day gains suggest institutional demand extends beyond the two largest crypto assets.
What sustained ETF demand means
Steady ETF demand can matter beyond the daily headline. It reduces available supply on spot exchanges. This dynamic has historically supported price during accumulation phases.
Nine straight days of buying signals broad institutional appetite. This demand is not narrow. Whether that appetite holds into next week may depend on Bitcoin and Ether extending their recent price gains.
