Multiple independent posts from The Kobeissi Letter on X and Facebook consistently report that U.S. small-cap and micro-cap equities experienced $837 million in outflows over the course of a single week. These accounts include repeated reporting of the same figure, along with contextual information such as the prior week's $1.2 billion record outflow and comparisons to historical averages. While the primary sources here are from a market commentary service and not an official exchange or fund flow dataset, the convergence and consistency across different posts by the same entity suggest they are reporting from a specific dataset. There are no contradictory claims in the provided sources, and one additional article referencing 'Small Cap Capitulation' also supports this figure. Given the alignment of multiple consistent references to this specific outflow figure, and the absence of evidence refuting it, the statement is likely true. However, the lack of confirmation from a high-authority primary market data provider (e.g., Bloomberg, LSEG, EPFR) slightly reduces the certainty to below absolute.
