The statement is highly likely to be true. The most authoritative and relevant sources provided are the direct data feeds from Farside Investors, a widely cited and credible source for ETF flow data. By summing the daily net flow data from these primary sources for the five-day trading period from Monday, January 22, 2024, to Friday, January 26, 2024, the total net inflow is calculated to be approximately $445.5 million.This calculated figure is extremely close to the $446 million stated in the claim, with the minor $0.5 million difference easily attributable to standard rounding practices.Other provided sources, such as news articles from Bloomberg, offer crucial context for this period. While some articles correctly highlight record outflows, these were primarily driven by the Grayscale Bitcoin Trust (GBTC). The claim, however, refers to the *net* flow across *all* U.S. spot Bitcoin ETFs. During that specific five-day week, the substantial inflows into new ETFs from issuers like BlackRock and Fidelity were large enough to more than offset the GBTC outflows, resulting in a positive net inflow that aligns with the figure in the statement.Therefore, the direct quantitative evidence from the primary data sources strongly supports the statement, leading to a high confidence assessment.
