Bitcoin’s Selloff Hit Abu Dhabi’s $764 Million ETF Bet. Its Next Move Was the Real Signal

Bitcoin’s latest institutional filing cycle delivered a quiet signal from Abu Dhabi: two of the emirate’s biggest state-backed investors watched the value of their spot Bitcoin ETF positions fall, but neither one cut a share.

The important detail is not the size alone. It is that the share count stayed put through a difficult quarter for Bitcoin.

According to CryptoSlate, Mubadala Investment Company and the Abu Dhabi Investment Council held a combined 22.94 million shares of BlackRock’s iShares Bitcoin Trust ETF, or IBIT, at the end of June. Neither investor reduced its reported share count during the second quarter.

The report estimates that Bitcoin’s decline erased roughly $118 million from the positions’ market value. It also notes that ADIC began reporting its position directly after the stake had previously appeared through subsidiary Al Warda Investments, a reporting change that did not alter beneficial ownership.

That distinction matters. The dollar value fell with the market, but the institutions themselves did not sell down the disclosed ETF positions.

CryptoSlate also placed the holdings inside Abu Dhabi’s broader digital-asset strategy, including the government-backed Hub71 ecosystem’s dedicated Web3 program. The unchanged ETF exposure therefore sits alongside a longer-running effort to build digital-asset infrastructure, not a single isolated trade.

The underlying regulatory records make the scale concrete. Mubadala’s SEC Form 13F information table lists 14,721,917 IBIT shares valued at $490,092,617 as of June 30.

The table identifies the security as iShares Bitcoin Trust ETF, lists the common-share interest under CUSIP 46438F101, and reports sole investment authority over the full position. It reports no shares under shared or other investment authority.

Those details are important because they come from the fund’s filed quarter-end snapshot, not a social-media estimate. The filing’s $490.1 million figure is the reported June 30 value; it is not a live valuation and will move with IBIT’s market price.

Form 13F captures holdings, not management’s next decision. It shows what Mubadala reported owning at quarter-end without revealing whether the fund plans to buy, sell, hedge, or hold after that date.

The separate Abu Dhabi Investment Council filing lists another 8,218,712 shares valued at $273,600,922. Its table identifies the same IBIT security, the same CUSIP 46438F101, and defined investment discretion over the full position, with all 8,218,712 shares reported under that authority.

Together, that is 22,940,629 shares with a reported quarter-end value of $763,693,539, all tied to BlackRock’s U.S.-listed spot Bitcoin fund.

The filings separate price damage from investor behavior. A lower dollar value can look like retreat when the asset itself is falling.

In this case, the reported share counts show something different: the two institutions absorbed the drawdown without shrinking the positions.

The ADIC record should also be read as a June 30 snapshot. It confirms the size and value reported on that date, while the comparison with the prior quarter supplies the key behavior signal: the share count remained unchanged even as the market value declined.

That is why the combined total is more useful than a dramatic dollar-loss figure by itself. One measures the market’s move; the other reveals what the disclosed holders actually did.

For the second sovereign investor, the filing therefore supplies two firm boundaries: a precise disclosed position at quarter-end and no evidence of a reduced share count during the period. Anything about its strategy after June 30 would go beyond the record.

That does not prove a new purchase is coming, and it does not tell us what either fund thinks Bitcoin will do next. It does show that a steep decline was not enough to force these two long-horizon investors out of their regulated Bitcoin exposure.

There is another limit worth keeping clear. Form 13F covers specified U.S.-listed securities.

It does not disclose direct Bitcoin held in private wallets, so the filings cannot confirm or rule out any separate sovereign-controlled holdings.

For Bitcoin investors, the clean takeaway is narrower and stronger than the usual institutional-adoption slogan: Abu Dhabi’s two disclosed IBIT positions lost value, but the sovereign investors behind them did not lose their nerve.
