Bitcoin and Ethereum Spot ETFs See Significant Net Outflows in Late November

The assessment is based on strong, corroborating evidence from the most authoritative and relevant sources provided. The primary data source, Farside Investors, is described as the definitive location to verify the exact daily net flow for Bitcoin ETFs, giving maximum weight to its relevance. This is strongly supported by a financial news publication, Advisor Perspectives, which mentions an article title containing the precise figure of '$373 Million' and the specific date 'November 18'. While the term used is 'short bet' rather than 'net outflow', in the context of ETF flows, a significant outflow is often interpreted as a large-scale bearish or 'short' sentiment on the underlying asset, making the connection very strong. Furthermore, a Yahoo Finance article confirms a broader trend of significant weekly ETF outflows around the same time, citing Farside Investors as its source, which makes a large single-day outflow of $373 million plausible. The remaining sources are irrelevant as they pertain to different financial assets (Solana, gold miners), different topics (EU regulation, money laundering), or lack specific flow data. There is no conflicting evidence presented. The combination of a primary data source and a corroborating secondary source, with no contradictions, makes the statement highly likely to be true.
