U.S. spot Bitcoin ETFs recorded $57.63 million in net outflows on August 14, according to SoSoValue data, marking the third consecutive trading day of withdrawals from the category. BlackRock's IBIT led the exodus with $55.51 million pulled out, while Bitwise's BITB was the lone fund to post a gain, taking in $6.14 million.
Spot Ether ETFs, by contrast, recorded zero net inflows or outflows for the session, a rare stall after a run of active trading in the category. Taken together, the two readings point to a broader pause in institutional appetite for crypto ETF exposure heading into the back half of August.
The three-day slide is part of a larger weekly pattern: spot Bitcoin ETFs recorded a combined $389.7 million in net outflows between August 10 and August 14, their largest weekly withdrawal in six weeks. Spot Ether ETFs also finished the week in negative territory, with about $2.25 million in net outflows over the same five-day stretch. Daily fund-level flow data for the category is tracked on SoSoValue's Bitcoin ETF dashboard.
A Mixed Picture Across Institutional Holders
The outflows arrive even as some institutions have been adding to their Bitcoin ETF exposure through other channels. Recent quarterly filings from major banks showed several quietly building call-option positions on spot Bitcoin funds during the second quarter, a reminder that daily fund flows and quarterly institutional positioning don't always move in the same direction, since a bank building options exposure isn't the same as fresh money flowing into the ETF itself day to day.
What to Watch Next
Three straight days of outflows isn't yet a trend reversal on its own, but a fourth consecutive day, or a widening of the daily outflow figure beyond $57.63 million, would be a stronger signal that institutional sentiment toward spot Bitcoin exposure is genuinely cooling rather than just pausing after a strong summer of inflows.
