Bitcoin ETFs cross $100 billion as nine-day inflow streak extends

Metric	Value
BTC ETF daily inflow	$242.24M
ETH ETF daily inflow	$234.51M
BTC ETF total assets	$100B+
BTC price (Aug 28)	~$79,500

US spot Bitcoin ETFs crossed $100 billion in total assets on Aug 27, as $242.24 million in net inflows extended their streak to nine sessions.

Spot Ethereum ETFs matched the pace with $234.51 million in inflows the same day, also marking a ninth consecutive session, according to CoinGlass data.

BlackRock's iShares Bitcoin Trust contributed $209 million of a $338 million haul on Aug 24, while its Ethereum fund added $90.92 million of that day's $116 million. Spot Solana ETFs drew $60.91 million and Hyperliquid funds $24.42 million on Aug 27, with XRP vehicles also posting gains.

The two flagship categories attracted a combined $2.3 billion last week, their largest weekly haul since October, as institutions built exposure to both assets rather than rotating between them. Bitcoin traded near $79,500 on Aug 28, up 1.1 percent over 24 hours, with Ether near $2,490.

Nine-Day Streak Spans Bitcoin, Ether and Altcoin Funds

The synchronized run began Aug 17, when both Bitcoin and Ether funds started climbing together, and continued without interruption through Aug 27. Wu Blockchain reported the Aug 27 figures, showing the two categories moving in near-perfect lockstep.

Total net assets across spot Bitcoin ETFs stood at $79.16 billion before the milestone, with category trading volume reaching $8.23 billion. The $100 billion crossing reflects the cumulative effect of sustained daily inflows that have absorbed available supply on spot exchanges.

Scale Gap Persists Between Flagship and Smaller ETFs

The gap between the flagship categories and smaller funds remains stark. BlackRock's IBIT alone accounted for $209 million of the $338 million that flowed into spot Bitcoin ETFs on Aug 24, while its ETHA fund drew $90.92 million of that day's $116 million Ethereum haul.

The $60.91 million into Solana ETFs and $24.42 million into Hyperliquid funds on Aug 27 point to broadening demand, though those vehicles remain far smaller and do not share the same registration status or disclosure standards as the US spot Bitcoin and Ether products.

Whether the streak holds into next week may depend on Bitcoin and Ether extending recent gains, with both up 5.4 percent over the past seven days. The nine-day run has coincided with Bitcoin's recovery toward the $80,000 area, keeping institutional flows firmly in focus.
