Bitcoin’s $16.3 billion Wall Street stress test splits into four positional patterns

An important story is making waves across the blockchain ecosystem. 3 billion in Bitcoin ETF positions that recently tracked ahead of the Q2 filing deadline resolved into four disclosed position patterns. Two Abu Dhabi filers held their ordinary ETF share counts steady, JPMorgan increased ordinary spot-ETF units, UBS shifted its disclosed long-options mix, and Morgan Stanley reduced external ETF units as a new branded wrapper appeared in its filing. The result answers ’s pre-deadline Bitcoin ETF stress test within strict limits.

The five filings arrived from Aug. 14, but each freezes reportable positions at June 30. Form 13F captures long securities and some held options while omitting short positions and written options, leaving each manager’s complete hedge book outside the frame.

Market Dynamics

The wider Bitcoin ETF complex recorded about $4. 89 billion of net outflows during Q2, based on ’s calculation from Farside Investors’ daily table. 06 billion of those net outflows came in the final five trading sessions of June.

The quarter-end filings show how unevenly that pressure appeared across reported holders and instruments. Bitcoin ETF holdings: the four-way map Adding these rows to a single exposure total would mix owned fund units with option underlying equivalents and a separately branded wrapper. Kept in their proper categories, the filings show four distinct responses to the same drawdown.

Market Impact

99% Bank and wrapper Morgan Stanley Bitcoin Trust shares Not reported 2,570,627 2,570,627 newly reported Sources: Morgan Stanley Q1 and Q2; JPMorgan’s amended Q1 restatement and Q2 filing; UBS Q1 and Q2; Mubadala Q1 and Q2; and Abu Dhabi Investment Council Q1 and Q2. The sovereign row is the clearest case of investors absorbing a lower mark. Mubadala held 14,721,917 shares of BlackRock’s iShares Bitcoin Trust at both March 31 and June 30, while ADIC held 8,218,712 shares at both snapshots.

Their reported market values fell anyway: Mubadala’s position declined from $565. 1 million, and ADIC’s moved from $315. Each position lost about 13.

35% of its reported value with no net share-count reduction between quarter ends. The identical unit counts identify price revaluation as the source of the lower marks. Two snapshots still leave room for intra-quarter sales and repurchases, and they say nothing about any direct Bitcoin positions.

This shift continues to shape the digital-asset landscape, with analysts examining its near-term effects.
