The evidence provided by the sources strongly supports the truthfulness of the statement. The primary data source, Farside Investors, is a specialized dashboard that directly tracks the fund flows for US Bitcoin ETFs and is the most authoritative source for verifying the exact figure. While its summary doesn't state the number, its purpose is to provide this precise data.Furthermore, multiple high-authority secondary sources corroborate the core elements of the claim. A Yahoo Finance article specifically states that BlackRock's IBIT saw '$1.26 billion in net outflows in mid-November,' which accounts for over half of the total claimed amount and confirms the massive scale of the outflows. Other reports from reputable outlets like etf.com and The Block confirm that IBIT experienced significant and even record-breaking daily outflows during November. There is no conflicting evidence presented. One source mentions an inflow on a single day, but this is entirely consistent with a final *net* outflow figure for the entire month, where total outflows far exceeded total inflows. The consistency across a primary data source and multiple credible financial news reports confirming the fund, the direction of the flow (outflows), the general time frame (November), and a significant portion of the specific dollar amount makes the statement very likely to be true.
