US cryptocurrency exchange-traded funds started the new week on a weaker footing on August 10, with spot Bitcoin ETFs recording approximately $144.6 million in net outflows and spot Ethereum ETFs losing another $14.6 million.
The reversal came immediately after one of the strongest weeks for institutional crypto demand since April. US Bitcoin ETFs attracted roughly $854 million between August 3 and August 7, while Ether ETFs brought in approximately $245 million.
Monday therefore represented a sharp change in direction rather than a continuation of last week’s accumulation.
BlackRock’s iShares Bitcoin Trust, IBIT, recorded the largest Bitcoin ETF redemption of the session, with approximately $53.56 million leaving the fund. Across the entire US spot Bitcoin ETF complex, net redemptions reached roughly $145 million.
Ethereum experienced a smaller but similarly important reversal. US spot Ether ETFs recorded $14.6 million in net outflows, ending a four-session run of positive flows.
Bitcoin’s Five-Day Inflow Streak Ends
The August 10 numbers interrupted a strong recovery in institutional Bitcoin demand.
During the previous trading week, Bitcoin ETFs recorded positive flows across all five sessions, accumulating approximately $854 million. BlackRock’s IBIT alone accounted for roughly $694 million of that weekly total, demonstrating how heavily the recovery had depended on the world’s largest asset manager.
The Monday reversal consequently stands out. IBIT went from being the principal source of new demand to the largest contributor to daily redemptions.
Even so, one negative session does not erase the previous week’s accumulation. The $144.6 million withdrawn Monday represents only around 17% of the roughly $854 million that entered Bitcoin ETFs during the preceding five sessions.
Bitcoin was trading around $65,000 as the flows were reported, with investors also positioning ahead of US inflation data. The relatively stable price despite ETF redemptions suggests the market absorbed the selling without a major deterioration in spot demand.
Ethereum Also Loses Momentum
Ethereum’s $14.6 million outflow was considerably smaller than Bitcoin’s in absolute terms, but it ended an increasingly important period of institutional accumulation. Ether ETFs attracted approximately $245 million during the August 3–7 week, their fifth consecutive positive week according to reported fund-flow data.
That performance had strengthened the argument that institutional investors were beginning to broaden allocations beyond Bitcoin. Ether funds had recently outperformed Bitcoin ETFs during some periods, supported by growing interest in stablecoins, tokenized assets and Ethereum’s role as settlement infrastructure.
Monday’s data provide an early test of whether that momentum can continue.
The combined Bitcoin and Ethereum ETF outflow on August 10 was approximately $159 million. While meaningful, it remains modest compared with the more than $1 billion the two categories collectively attracted during the previous week.
The latest session therefore looks more like a pause in institutional accumulation than evidence of a wholesale retreat.
What happens next will be more consequential. If redemptions continue across several sessions, August 10 could mark the beginning of another risk-reduction cycle. If inflows quickly resume, Monday’s withdrawals may instead prove to be routine profit-taking after the strongest weekly demand in months.
For now, the message from regulated crypto funds has changed: after five days of aggressive accumulation, institutional investors started the week by taking money off the table.
