U.S. spot Bitcoin exchange-traded funds recorded $131.1 million in net outflows on August 13, more than doubling the previous session’s withdrawals as investors continued reducing exposure to the largest cryptocurrency.
The selling contrasted with smaller but positive flows into Ethereum and Solana products. Spot Ether ETFs attracted approximately $6.7 million, while Solana funds recorded around $3.6 million of net inflows.
For Bitcoin, August 13 marked the second consecutive negative session after $61.1 million left the funds on August 12. Across the two sessions, investors withdrew approximately $192.2 million from U.S. spot Bitcoin ETFs.
The figures point to continued fragmentation in institutional crypto demand rather than a uniform retreat from digital assets.
Fidelity and ARK Lead Bitcoin Withdrawals
ARK 21Shares’ ARKB recorded the largest Bitcoin ETF redemption on August 13 at $58.8 million, closely followed by Fidelity’s FBTC with $55.1 million.
Grayscale’s GBTC lost another $36.3 million, while Bitwise’s BITB posted a $9.3 million outflow. Invesco’s BTCO shed $7.9 million, WisdomTree’s BTCW lost $4.0 million and BlackRock’s IBIT registered a comparatively modest $5.7 million withdrawal.
Two products moved against the broader trend. Grayscale’s lower-cost Bitcoin Mini Trust attracted $38.9 million, while Morgan Stanley’s MSBT added $7.1 million. Those inflows offset part of the selling elsewhere and brought the category-wide net withdrawal to $131.1 million.
The deterioration from August 12 was significant. Bitcoin ETF outflows accelerated by $70 million session over session, or roughly 115%, after Fidelity had already led the previous day’s selling with $46.8 million in withdrawals.
Bitcoin itself traded around $63,000-$64,000 during August 13, remaining under pressure despite softer U.S. inflation data that might ordinarily have supported risk assets.
Ether and Solana Continue to Attract Capital
Ethereum ETFs remained positive, recording $6.72 million of net inflows on August 13, according to SoSoValue data. Grayscale’s Ethereum Mini Trust led the category with $6.47 million, while Morgan Stanley’s recently launched MSSE added approximately $811,000. BlackRock’s ETHA recorded a relatively small $569,000 outflow.
The result followed approximately $7.4 million of Ether ETF inflows on August 12, taking combined net creations over the two sessions to roughly $14.1 million.
Ethereum ETF assets stood at approximately $10.57 billion following the August 13 session, with cumulative net inflows of about $11.45 billion. Solana ETFs also remained positive, attracting approximately $3.6 million during the latest session after roughly $9 million flowed into the category on August 12. Solana ETF assets remained around $926 million.
The divergence is increasingly notable. Across Bitcoin, Ethereum and Solana, the three categories recorded an aggregate net outflow of roughly $120.7 million on August 13, but Bitcoin accounted for more than the entire decline.
Two sessions do not establish a sustained institutional rotation. Nevertheless, the August 13 data show investors simultaneously redeeming significant amounts from established Bitcoin products while continuing to allocate smaller amounts toward Ether and Solana.
With Bitcoin ETF withdrawals accelerating from $61.1 million to $131.1 million in consecutive sessions, the next several trading days will indicate whether the move represents short-term portfolio repositioning or the beginning of a more persistent institutional risk reduction.
