US spot Bitcoin ETFs recorded $61.16 million in net outflows on August 12, a sharp reversal from the prior session's modest inflows. SoSoValue data shows Fidelity's FBTC led the redemptions with $46.82 million pulled out, while BlackRock's IBIT — which has dominated inflows for most of the year — also saw $14.34 million in net outflows, an unusual showing for the fund that has typically anchored the category's gains.
The reversal is notable given where flows stood just a day earlier. On August 11, Bitcoin spot ETFs posted a modest $4.89 million in net inflows, with IBIT the only fund in the category to see money come in at all. The swing from a thin inflow led entirely by BlackRock to a broader outflow led by Fidelity within 24 hours illustrates how quickly sentiment has been shifting around Bitcoin exposure products.
Ether ETFs Move the Other Direction
Spot Ether ETFs told a different story, posting $7.38 million in net inflows on the same day even as their Bitcoin counterparts bled assets. The divergence adds to a pattern that's shown up repeatedly in recent weeks, where Ether funds have drawn steadier interest while Bitcoin ETF flows have swung between modest gains and outright redemptions.

Total Bitcoin ETF Assets Still Near $77 Billion
Despite the daily outflow, the category remains substantial in aggregate: total net assets across US spot Bitcoin ETFs stood at roughly $77.4 billion as of the same day, representing about 6.06% of Bitcoin's total market capitalization. A single day of outflows, even one led by a fund as large as FBTC, represents a small fraction of that total — but the reversal from IBIT-led inflows to Fidelity-led redemptions in the span of a day underscores how sensitive these flows remain to shifting short-term sentiment around Bitcoin's price action.
