Spot Bitcoin ETFs Record $242 Million Inflow, Extending Nine-Day Streak

Spot Bitcoin exchange‑traded funds (ETFs) attracted $242.30 million in net inflows on Aug. 27, extending a run of daily net purchases to nine straight trading days. Spot Ethereum ETFs matched the momentum, recording $235 million in net inflows on the same day.

Institutional Buying Drives Parallel Streaks

The parallel inflow streaks follow a period of heavy institutional buying. BlackRock’s iShares Bitcoin Trust (IBIT) contributed $209 million of a $338 million Bitcoin ETF inflow on Aug. 24, while its Ethereum fund (ETHA) added $90.92 million of that day’s $116 million Ethereum ETF haul.

Market Context

• Bitcoin traded near $80,000, up 2.12 % over 24 hours.
• Ethereum traded near $2,480.
• Total net assets across spot Bitcoin ETFs reached $79.16 billion.
• Trading volume for the Bitcoin ETF category hit $8.23 billion.
• The two categories together drew $2.3 billion in the most recent week, the largest combined weekly inflow since October.

Smaller Crypto ETFs Also See Inflows

Spot Solana ETFs added $60.91 million and spot Hyperliquid ETFs attracted $24.42 million on Aug. 27, indicating institutional demand beyond the two largest crypto assets.

Implications

Steady inflows reduce the supply of spot assets on exchanges, a factor that has historically supported price during accumulation phases. The nine‑day buying streak across both Bitcoin and Ethereum ETFs suggests a broad institutional appetite rather than a narrow focus on a single asset.
