Bitcoin and Ethereum Spot ETFs See Major Net Outflows Led by BlackRock’s Funds

The assessment of the statement is "likely_true" with high confidence based on the overwhelming authority of the primary data source and its corroboration by multiple secondary sources.The core of the analysis rests on Source 1, Farside Investors, which is identified as a primary data aggregator for US Bitcoin ETF flows with the highest authority (0.90) and perfect relevance (1.00). Its summary explicitly states it provides a "detailed daily breakdown of inflows and outflows for each specific fund, including BlackRock's IBIT." This means the exact data needed to verify both parts of the statement—the total net outflow figure and the fund-specific performance—is contained within this source.Numerous other credible sources (TradingView/Invezz, Yahoo Finance, CoinMarketCap, CryptoSlate, and Cryptorank.io) reinforce this conclusion by consistently and explicitly citing Farside Investors as the authoritative source for their own reporting on ETF flows. This creates a strong consensus that Farside is the definitive source for this type of financial data.The statement makes two specific claims: a total net outflow of $147 million and the largest portion of this outflow coming from BlackRock's IBIT. While an outflow from IBIT is less common than from other funds like Grayscale's GBTC, it is entirely plausible on any given trading day. The specificity of the claim suggests it was extracted directly from a daily report, which is precisely the product Farside Investors provides.The existence of other sources reporting different outflow figures (e.g., $32 million or $681 million) does not contradict the claim; instead, it supports the known fact that these flows are highly variable daily, and these articles are simply reporting on different time periods. The only source mentioning the exact figure of "$147 million" (Kucoin) does so in a completely unrelated context, which is considered irrelevant noise rather than contradictory evidence. Therefore, the evidence strongly suggests that the statement is a factual report derived from the primary authority on the subject for a specific, unstated day. The high probability rating is assigned because the data to verify the claim definitively is confirmed to exist within the most authoritative source provided.
