UBS Discloses Increase in BlackRock Bitcoin ETF Holdings to Approximately $90 Million

TechFlow reports that on August 14, UBS's Form 13F filing with the U.S. Securities and Exchange Commission showed that as of June 30, 2026, its disclosed holdings in the BlackRock iShares Bitcoin Trust were approximately 2.5 million shares, valued at nearly $90 million, a significant increase from approximately 549,000 shares at the end of 2025.

The document also showed that the holding is a securities position under the reporting basis where UBS exercises investment management authority, not necessarily held entirely with UBS's proprietary funds, and may also include client account holdings. The article pointed out that this scale remains a limited allocation compared to UBS's overall assets under management, but reflects its continued expansion of Bitcoin-related exposure through compliant securities instruments.
