Total net assets across spot Bitcoin ETFs stood at $79.16 billion as of the latest update. BTC traded over $80,000 at the time of writing.

Ether ETFs Post Sixth Straight Day of Gains

BlackRock’s ETHA supplied $90.92 million of the day’s $116 million Ethereum ETF haul, about 78% of the total, per SoSoValue. Grayscale’s Ethereum Mini Trust added $12.50 million, the second-largest contribution.

The result builds on the biggest Ether ETF inflow in 10 months, recorded earlier in August. Ether changed hands near $2,486, up 2.4% over 24 hours.

BlackRock is the world’s largest asset manager, with $15.3 trillion in assets under management as of June 30, 2026. It led inflows across both crypto ETF categories on Aug. 24.

That dual dominance suggests BlackRock remains the primary entry point for institutional crypto exposure. The pattern held through most of August.
