BlackRock's IBIT emerged as the dominant vehicle, capturing approximately $170 million—representing over 80% of total Bitcoin ETF inflows. This level of concentration underscores the institutional preference for products offered by established asset managers with substantial distribution networks and regulatory credibility.
Concurrent with Bitcoin strength, Ethereum ETFs attracted $53.75 million in inflows, with BlackRock's ETHA leading the category. The ETHA fund has announced a 1-for-3 reverse share split scheduled for October 6, a strategic move designed to elevate the per-share price and reduce per-share trading costs, potentially improving market accessibility and liquidity for institutional participants.
The August 4 inflows represent part of a broader momentum surge in crypto ETF markets. Bitcoin ETFs posted their strongest week since April 2026, accumulating $853.54 million in net inflows across the August 3–7 window. This weekly progression—Monday $170 million, Tuesday $211 million, Wednesday $244 million—suggests sustained institutional buying interest and positions crypto ETFs as a meaningful allocation vehicle within diversified institutional portfolios.
Secondary cryptocurrency ETFs displayed more muted activity.
