[Christmas Week Spot Bitcoin ETF Net Outflow of $782 Million] Data from December 29 shows that U.S.-listed spot Bitcoin ETFs saw a cumulative net outflow of approximately $782 million during Christmas week, with a single-day outflow of $276 million on Friday, marking the peak outflow during the holiday period. BlackRock's IBIT experienced a single-day outflow of nearly $193 million, Fidelity's FBTC saw an outflow of about $74 million, and Grayscale's GBTC continued with small-scale redemptions. The total asset size of spot Bitcoin ETFs dropped to approximately $113.5 billion, down from over $120 billion at the beginning of December. Bitcoin's price remains near $87,000, with the outflows possibly linked to year-end asset rebalancing and reduced liquidity during the holiday season.
