Morgan Stanley’s Bitcoin Trust and Grayscale’s Bitcoin Mini Trust ETF were the only US spot Bitcoin funds to attract capital on Aug. 13, offsetting part of a broad withdrawal that pushed the group to $131.1 million in net outflows for the session.

Morgan Stanley Bitcoin Trust added $7.1 million, while Grayscale’s smaller Bitcoin fund took in $38.9 million, according to SoSoValue data. Their combined $46.0 million of inflows contrasted with $177.1 million of gross outflows across seven other products.

The divergence was particularly sharp within Grayscale’s own lineup. GBTC lost $36.3 million, but the Mini Trust’s inflow was large enough to leave the asset manager’s two products a combined $2.6 million positive for the day.

This outflow comes as Bitcoin dropped below $63,000 to as low as $62,487 during the last 24 hours, per CryptoSlate's data.

Fidelity and ARK drive broad redemptions

The positive flows into Morgan Stanley and Grayscale’s Mini Trust came as withdrawals spread across most of the US spot Bitcoin ETF complex.

ARK 21Shares Bitcoin ETF recorded the largest outflow at $58.8 million, followed by Fidelity’s FBTC at $55.1 million. Together, the two products accounted for $113.9 million, or 64.3% of gross outflows among the seven funds that posted withdrawals.

Bitwise’s BITB shed $9.3 million, while Invesco’s BTCO lost $7.9 million. BlackRock’s IBIT posted a comparatively modest $5.7 million outflow, and WisdomTree’s BTCW lost $4.0 million.

That distribution made Aug. 13 notable less for any single dominant redemption than for the number of products participating. Even BlackRock’s IBIT, which has frequently been one of the strongest sources of inflows in the category, finished the session negative.

Four sessions erase part of the prior rebound

Meanwhile, the Aug. 13 withdrawals extended a weaker stretch for Bitcoin ETF demand without fully reversing the previous week’s rebound.

US spot Bitcoin ETFs recorded $332 million in net outflows across the four sessions through Aug. 13. The group lost $144.6 million on Aug. 10, attracted $4.8 million on Aug. 11, then posted outflows of $61.1 million on Aug. 12 and $131.1 million on Aug. 13.

The sequence was therefore not an uninterrupted outflow streak, but it marked a clear reversal from the preceding week's sessions. During this period, the funds attracted $853 million, according to SoSoValue data.

The subsequent $332.0 million withdrawal erased about 38% of that gain, leaving the combined flows for this month at $521 million net positive.

The next completed session will show whether the Aug. 13 split, with Morgan Stanley and Grayscale’s Mini Trust attracting capital while most competing products lost assets, persists or proves to be a one-day divergence.
