CryptoBriefing and Bitcoin Magazine both cite 13F filings for Mubadala and Abu Dhabi Investment Council-linked Bitcoin ETF holdings, but disagree on the dollar values and on whether positions changed quarter-over-quarter.
CryptoBriefing and Bitcoin Magazine both cite 13F filings for Mubadala and Abu Dhabi Investment Council-linked Bitcoin ETF holdings, but disagree on the dollar values and on whether positions changed quarter-over-quarter.
What all sources agree on
- Mubadala Investment Company and an Abu Dhabi Investment Council-linked entity hold positions in BlackRock's iShares Bitcoin Trust (IBIT).
- The disclosures come from SEC 13F filings.
- BlackRock's IBIT has been highly successful since its January 2024 launch.
Where the reports disagree
1Whether holdings increased or stayed flat quarter-over-quarter
The latest filing shows a 16% increase from the roughly 12.7 million shares Mubadala held at the end of 2025.
Both wealth funds’ position in Bitcoin is unchanged since last quarter.
What would settle it: The underlying SEC 13F filings for Mubadala Investment Company and the Abu Dhabi Investment Council-linked entity for the relevant quarters.
2Dollar value and share count of Mubadala's IBIT position
Mubadala alone accounts for 14.7 million IBIT shares valued at approximately $565.6 million as of March 31.
Abu Dhabi’s Mubadala Investment Company disclosed Friday that it held a $490 million stake in BlackRock’s iShares Bitcoin Trust — the second-largest single holding across its entire 13F portfolio.
What would settle it: Mubadala Investment Company's SEC 13F filing.
3Dollar value of the Abu Dhabi Investment Council-linked entity's position
Al Warda holds around 8.2 million shares, bringing the combined position to the $764 million figure.
And a Thursday filing from the Abu Dhabi Investment Council, another state-run fund, revealed a $273.6 million position in the popular Bitcoin exchange-traded fund.
What would settle it: The Abu Dhabi Investment Council-linked entity's SEC 13F filing.
What to make of it
Treat only the existence of IBIT positions held by Mubadala and an Abu Dhabi Investment Council-linked entity as established; the specific dollar amounts and whether the holdings grew or held steady this quarter are contested and unresolved pending direct review of the SEC filings.
