The Form 13F deadline landed on August 14, and the quick read wrote itself: institutions dumped their Bitcoin ETF holdings in the second quarter. The aggregate backs it up. US spot Bitcoin ETF products bled close to $4.89 billion in the three months to June, and BlackRock's IBIT alone accounted for roughly $2.95 billion of that.
Then you open the filings from the largest managers, and the flight narrative starts to wobble.
JPMorgan bought a quarter more, not less
JPMorgan lifted its spot Bitcoin ETF shares from 8,462,883 to 10,623,591 across the quarter. That is an addition of 2,160,708 units, or 25.53 percent, and most of it landed in IBIT, where its stake climbed from about 8.3 million shares to 10.4 million. UBS played it quieter. Its ordinary shares rose only 13 percent, but the call options it holds against Bitcoin funds jumped from 80,000 underlying shares to 1,950,000, while its puts fell by more than half. A desk does not build a call book that size on the way out the door. The flow picture across spot funds has been choppy for weeks, which makes the direction of the big accounts the number that actually tells you something.
| Filer | Q1 shares | Q2 shares | Change |
|---|---|---|---|
| JPMorgan (spot ETF) | 8,462,883 | 10,623,591 | +25.53% |
| UBS (ordinary) | 365,894 | 414,191 | +13.20% |
| Mubadala (IBIT) | 14,721,917 | 14,721,917 | flat |
| Abu Dhabi Investment Council | 8,218,712 | 8,218,712 | flat |
| Morgan Stanley (external) | 19,411,356 | 18,636,055 | -3.99% |
Morgan Stanley's cut was a change of address
On paper Morgan Stanley trimmed. Its external spot-ETF holdings slipped from 19,411,356 shares to 18,636,055, down 3.99 percent, and that is the line most summaries stopped at. The filing carried a second entry they skipped. A new Morgan Stanley Bitcoin Trust now holds 2,570,627 shares. Fold the in-house wrapper back in and the combined position reaches 21,206,682 shares, roughly 9.25 percent above where the bank sat a quarter earlier. The money did not leave Bitcoin. It moved out of a rival's fund and into one Morgan Stanley collects fees on itself.
The sovereign money did the least and paid for it. Mubadala held its 14,721,917 IBIT shares unchanged and watched the value fall from $565.6 million to $490.1 million, a 13.35 percent loss on a position it chose not to touch. Abu Dhabi Investment Council did the same with its 8.2 million shares. Neither fund sold. Both are down double digits and sitting still, a reminder that large passive holders can park a fortune and forget it.
So who actually sold
The selling clustered in the smaller, more tactical books rather than the names that set the tone. Intesa Sanpaolo cut its IBIT stake by 93.7 percent, from 646,809 shares to 40,723, and opened a fresh put equivalent to 500,000 shares on top. That is what a real exit looks like, and it came from a European bank managing a relatively modest book of client positions, not from the desks that anchor the market.
Sort the Bitcoin ETF cohort by who runs the money and it splits cleanly. The bank-managed books added or repackaged. The passive sovereign allocations sat frozen. The tactical accounts took profits or hedged. That is not one market fleeing a Bitcoin ETF trade in unison. Institutional money tends to arrive late and leave in a hurry anyway; crypto priced SpaceX before Wall Street did, then watched Wall Street show up for the top.
The split matters for what comes next. Bloomberg Intelligence puts the average institutional entry near $82,249, which leaves the cohort about 22 percent underwater at current prices. The holders who added into that drawdown, JPMorgan among them, are wagering the mark recovers before the next filing window. The Q3 numbers, due in November, will show whether the banks that leaned in this quarter kept their nerve or quietly joined the accounts already backing away.
