According to @rovercrc, BlackRock purchased $169.3 million worth of Bitcoin (BTC) (source: Crypto Rover post on X, Sep 10, 2025). The post does not include transaction evidence, ETF flow data, or a link to an official BlackRock filing (source: same X post). Traders should seek confirmation via the iShares Bitcoin Trust (IBIT) daily holdings and flow updates published by BlackRock (source: BlackRock iShares official site). Official confirmations can also appear in SEC filings such as prospectuses, 8-Ks, or 13F reports (source: U.S. SEC EDGAR). If IBIT shows net share creations of a similar magnitude, that would imply corresponding spot BTC purchases under the ETF creation mechanism (source: IBIT prospectus filed with the SEC).
