Spot Bitcoin ETFs have faced a challenging period, recording a total of $2.3 billion in outflows over the past two weeks, with $333.7 million withdrawn just on Tuesday. This marks the seventh consecutive day of net outflows, with BlackRock's ETFs leading the withdrawals at $192.4 million, followed by Fidelity and Grayscale. The ongoing trend has erased approximately $1.88 billion from spot Bitcoin ETF products, the longest streak of outflows since December 2025. Analysts attribute these withdrawals to a combination of macroeconomic uncertainty, portfolio adjustments, and a growing interest in AI stocks, reflecting Bitcoin's evolution into a macro-risk asset. Despite the negative flow data, a significant transaction involving 29.2 million shares of BlackRock's Bitcoin ETF was noted, contributing to a total trading volume of $4.4 billion, the highest since April 17. This suggests that institutional interest in Bitcoin may still be strong, as the market absorbed the large order without significant price disruption, indicating potential bullish sentiment for future adoption.
