Abu Dhabi Funds Held Every IBIT Share Through a $118 Million Loss

New 13F filings show Mubadala Investment Company and Abu Dhabi Investment Council absorbed a combined $118 million paper loss on their iShares Bitcoin Trust positions last quarter as $BTC declined, yet neither fund cut a single share. Together they held 22.94 million IBIT shares worth $764 million at June 30, down from $881 million three months earlier. November's 13F window is when the market learns whether that conviction outlasted the summer.

Key takeaways

  • Mubadala Investment Company and Abu Dhabi Investment Council together held 22.94 million IBIT shares worth $764 million at June 30, down from $881 million three months earlier, absorbing a combined $118 million paper loss without selling a single share.
  • Share counts were identical across both quarters—Mubadala at 14.72 million and the Investment Council at 8.22 million—so only the price moved.
  • For Mubadala, IBIT is 1.4% of a $34.77 billion US equity book, while for the Investment Council its $274 million IBIT position equals 38% of a $714 million US portfolio and is its largest disclosed holding.
  • Bitcoin fell 17.9% in June, closing at $58,559 and pulling the combined position $302 million below its May peak of roughly $1.07 billion.
  • Elsewhere, Intesa Sanpaolo cut its IBIT holding by 93.7% and rotated toward staked Ethereum products, and the average US spot Bitcoin ETF buyer sat 22% underwater at the end of July.

New 13F filings show Mubadala Investment Company and Abu Dhabi Investment Council absorbed a combined $118 million paper loss on their iShares Bitcoin Trust positions last quarter as $BTC declined, yet neither fund cut a single share. Together they held 22.94 million IBIT shares worth $764 million at June 30, down from $881 million three months earlier. November's 13F window is when the market learns whether that conviction outlasted the summer.

The quarter-end print understates the actual swing. $BTC opened April near $68,079 and climbed to $82,139 by May 10. IBIT touched $46.47 the following day, and at that level the Abu Dhabi stake was worth roughly $1.07 billion. June reversed it. Bitcoin shed 17.9% that month and closed at $58,559, pulling the combined position $302 million below its May peak.

Mubadala filed its 13F on August 14. The Abu Dhabi Investment Council disclosed its book one day earlier. Share counts are identical across both quarters: Mubadala at 14.72 million, the Investment Council at 8.22 million. Only the price moved.

Position size tells two different stories

For Mubadala, IBIT is 1.4% of a $34.77 billion US equity book where chipmaker GlobalFoundries occupies 94.7%. The Bitcoin ETF ranks second on that list, but it is satellite exposure against a concentrated industrial anchor.

The Investment Council runs a tighter book. Its $274 million IBIT position equals 38% of a $714 million US portfolio and is the fund's largest disclosed holding. A 17.9% Bitcoin month lands differently at that concentration.

Neither fund disclosed a second crypto product. Mubadala had added IBIT in Q1, during the same quarter Harvard cut its stake by 43%.

The rest of the institutional tape

Conviction elsewhere cracked. Intesa Sanpaolo, Italy's largest banking group, cut its IBIT holding by 93.7% in the period and rotated toward staked Ethereum products. Spot Bitcoin funds shed 3,170 BTC in late July. Ethereum funds drew inflows for a third straight week. The average US spot Bitcoin ETF buyer sat 22% underwater at end of July.

$BTC traded near $62,957 on Saturday, valuing the network at $1.26 trillion, still nearly 50% below the record of $126,080 set on October 6, 2025. Watch the November 13F filings: that disclosure shows whether Abu Dhabi held through the summer drawdown or quietly trimmed.
