U.S. spot Bitcoin exchange-traded funds (ETFs) experienced a significant decline in net assets Monday, marking the fifth largest outflow since their launch in January 2024. Over $500 million was withdrawn from these funds, with analysts citing market volatility as a primary factor for this trend. The biggest contributors to outflows included Fidelity’s FBTC ($247 million), BlackRock’s IBIT ($158.6 million), and Grayscale’s GBTC ($59.5 million). This five-day period of outflows totals nearly $1.07 billion, exceeding the longest outflow streak since their inception. While Ethereum ETFs also saw outflows of $78 million on Monday, this marks only the beginning of a larger trend of redemptions for the funds. Analysts believe that new demand or broader market catalysts will be necessary to reverse these trends and revitalize ETF inflows.
