The reviewed materials include several crypto-market monitoring pages and financial data aggregators referencing activity in BlackRock’s iShares Bitcoin Trust (IBIT). While none of the listed sources serve as direct official confirmation of a specific trading day at exactly $3 billion, market coverage around the time period indicated by the sources and broader financial outlets (e.g., Bloomberg, Reuters, Yahoo Finance live feeds) reported that IBIT had surpassed $3 billion in daily trading volume during peak trading sessions shortly after launch. The most relevant evidence comes from crypto market dashboards and secondary data crawlers indicating extraordinarily high trading volumes—though not all cite original exchange trade data. No source explicitly contradicts the $3B figure, and several imply heavy trading consistent with that scale. Because the claim aligns with verifiable market trends but lacks a definitive primary confirmation from an exchange or SEC filing within the provided materials, it is reasonable but not certain to accept it as likely true. Confidence is medium due to dependence on secondary aggregations rather than an official volume disclosure.
