U.S. spot Bitcoin ETFs’ year-to-date flows have turned negative: they saw net outflows of $1.28 billion last week, their worst week since late June and the second consecutive week of net outflows. According to The Block, citing SoSoValue data, the 12 funds have recorded year-to-date net outflows of about $914 million—the roughly $368 million in year-to-date net inflows they still had at the start of the week was completely wiped out in a single week. The funds collectively hold about $95.9 billion worth of Bitcoin, approximately 6.3% of Bitcoin’s total market capitalization. If this trend continues through year-end, 2026 will be the first full year of net outflows for spot Bitcoin ETFs since their launch in January 2024 (net inflows of $35.2 billion in 2024 and $21.4 billion in 2025).$BTC $ETH
