Key Takeaways UBS raised direct IBIT holdings by 11.9%. Call exposure surged more than 23-fold. Put exposure fell roughly 53%. The viral 230% figure mixes different instruments. According to
According to a Form 13F filed with the U.S. Securities and Exchange Commission on August 13, UBS Group reported 407,890 shares of the iShares Bitcoin Trust ETF (IBIT) as of June 30.
That was up from 364,371 shares at the end of March, an increase of 11.9%.
Its options positions changed far more dramatically. Reported IBIT calls jumped from exposure equivalent to 80,000 underlying shares in March to 1.95 million shares in June, an increase of roughly 2,338%.
Put exposure moved the other way, falling from 303,300 to 143,300 underlying shares, or about 53%.
Claims that UBS increased its “spot Bitcoin ETF holdings” by roughly 230% rely on combining positions that the SEC filing reports separately.
UBS ended June with:
Together, they amount to about 2.50 million underlying share equivalents. The comparable Q1 positions totaled about 747,671, producing an increase of roughly 234.5%.
But that does not mean UBS increased its spot IBIT holdings by 234.5%.
The ordinary ETF position rose only 11.9%. Most of the increase came from options, which the SEC requires filers to identify separately as calls or puts.
The dollar figures need the same distinction.
UBS’s ordinary IBIT shares were valued at approximately $13.58 million in the June filing. Its calls were reported against roughly $64.92 million of underlying IBIT value, while puts represented another $4.77 million.
Adding all three produces about $83.26 million, but that is not the same as UBS owning $83.26 million of IBIT.
For long options, Form 13F reports positions with reference to the securities underlying the contracts. The figures therefore should not be read as the amount UBS paid for the options themselves.
Using a later IBIT market price to value all 2.50 million share equivalents can push the headline number toward $90 million, but it still combines direct ETF ownership with call and put exposure.

UBS went from calls representing 80,000 underlying IBIT shares to 1.95 million in three months, while cutting its reported put position by more than half.
That is a very different development from a simple Bitcoin ETF buying spree.
There are also limits to what can be inferred from the filing. Form 13F does not reveal an institution’s entire derivatives book. Written options, for example, are not reported in the same way, so the disclosed calls and puts cannot be treated as UBS’s complete net directional exposure.
The SEC addresses these reporting rules in its Form 13F guidance.
UBS Group also submitted the filing as a combination report covering multiple UBS entities. The positions therefore should not automatically be described as a single $83 million corporate Bitcoin bet by the bank itself.
The filing shows something more specific: UBS modestly increased its direct IBIT holdings during Q2, dramatically expanded its reported call exposure and cut its put exposure by roughly half.
That makes the 2,338% jump in calls, rather than a supposed 230% surge in spot Bitcoin ETF ownership, the standout change in the latest filing.
