US spot Bitcoin ETFs recorded $131.1 million in net outflows on Aug. 13, with Morgan Stanley Bitcoin Trust and Grayscale Bitcoin Mini Trust ETF the only products to take in new money. Morgan Stanley added $7.1 million and Grayscale’s smaller Bitcoin fund drew $38.9 million, partly offsetting $177.1 million of gross withdrawals across seven other funds, according to SoSoValue. The split was especially pronounced within Grayscale’s lineup, where GBTC lost $36.3 million but the Mini Trust’s inflow left the firm’s two Bitcoin products $2.6 million net positive for the day. The withdrawals came as Bitcoin fell below $63,000 and traded as low as $62,487 over the past 24 hours, according to CryptoSlate's data. ARK 21Shares Bitcoin ETF led redemptions with $58.8 million, followed by Fidelity’s FBTC at $55.1 million, while Bitwise’s BITB, Invesco’s BTCO, BlackRock’s IBIT and WisdomTree’s BTCW also posted outflows. Over the four sessions through Aug. 13, the group logged $332.0 million in net outflows, reversing part of the prior week’s $853 million rebound and leaving the month $521 million net positive. The next session may show whether the divergence between the two inflow funds and the broader ETF group was temporary or the start of a more durable shift.
