Two Abu Dhabi sovereign investors kept their BlackRock Bitcoin ETF holdings unchanged through the second quarter, retaining $764 million of exposure even as the cryptocurrency remained mired in one of its steepest annual declines.
Mubadala Investment Company and the Abu Dhabi Investment Council held a combined 22.94 million shares of BlackRock’s iShares Bitcoin Trust ETF (IBIT) as of June 30, regulatory filings show.
Neither reduced its share count during the quarter.
The decision meant the funds absorbed the decline in IBIT. Their combined positions were valued at about $881.4 million at the end of March, implying roughly $118 million of value was erased during the second quarter even though the number of shares remained unchanged. Mubadala’s stake alone fell in reported value to $490.1 million from $565.6 million.
Mubadala held 14,721,917 IBIT shares as of June 30, the same amount it owned three months earlier. The position remained its second-largest reported holding in its $34.8 billion 13F portfolio, behind GlobalFoundries.
The sovereign investor had increased its position by almost 16% during the first quarter, adding more than 2 million shares as Bitcoin weakened. It had previously boosted the stake by about 46% in the final quarter of 2025.
Abu Dhabi Investment Council (ADIC) also stood pat, retaining 8,218,712 IBIT shares worth about $273.6 million as of June 30. IBIT was its largest reported US-listed position, accounting for over 33% of its roughly $715 million 13F portfolio.
ADIC began reporting the position directly earlier this year after its subsidiary Al Warda Investments had previously disclosed the stake. The reporting change did not alter the beneficial ownership of the shares.
