Mubadala Discloses 46% Increase in Bitcoin ETF Holdings
Abu Dhabi’s Mubadala raised its stake in BlackRock’s iShares Bitcoin Trust to $630.6 million, according to regulatory filings and press reports.
Mubadala Investment Company disclosed in a filing with the U.S. Securities and Exchange Commission that its position in the iShares Bitcoin Trust (IBIT) reached 12.7 million shares, valued at $630.6 million as of Dec. 31, representing roughly a 46% increase from the 8.7 million shares previously reported [1][2][3].
The Q4 disclosures show other institutional participants also adjusted IBIT allocations: Jane Street reported an increase in its holdings alongside Mubadala, with filings indicating Jane Street added approximately 7 million IBIT shares [6].
Separate reporting places the UAE’s overall sovereign Bitcoin exposure at higher levels, with one outlet estimating the country’s combined sovereign positions and mining activity exceed $900 million and that more than $500 million of that exposure comes from IBIT holdings via state-backed funds [4].
Regulatory filings and media reports show rising allocations to Bitcoin ETFs by Mubadala and other institutional actors, reflecting increased institutional exposure documented in recent disclosures [1][2][6].
