Bitcoin ETFs flip negative for 2026 after $1.28 billion outflow week, worst since June

Bitcoin Exchange-Traded Funds (ETFs) have experienced a significant downturn, recording their worst performance since June and turning negative for 2026. This decline follows a substantial $1.28 billion outflow week. A major contributor to this trend was BlackRock's IBIT, which accounted for a dominant 98% of Friday's outflows alone, with an estimated $403 million exiting the industry-leading fund.
