Fact Check
Multiple high-authority and relevant sources, including official SEC 13F filing data compiled by Quiver Quantitative and a reputable crypto industry news outlet, confirm that Mubadala disclosed ownership in BlackRock’s iShares Bitcoin Trust valued around $630.6 million. The data from the SEC filings constitutes a primary source, directly supporting the existence and size of the position. The amount cited ($630.6 million) aligns closely with reported valuations of 12,702,323 shares, at the period-end price. While one research outlet presents a lower figure (~$436.9M), this discrepancy may be attributable to valuation date differences or partial holdings being reported earlier. Most other mentions in relevant sources corroborate the $630 million figure. The weight of evidence, including the direct primary data, substantially supports the statement's truthfulness despite minor inconsistencies in one source.
