[UBS Discloses Increase in BlackRock Bitcoin ETF Holdings to Approximately $90 Million] Deep Tide TechFlow reports that on August 14, UBS submitted a 13F filing to the U.S. Securities and Exchange Commission, revealing that as of June 30, 2026, its disclosed holdings in the BlackRock iShares Bitcoin Trust Fund amounted to approximately 2.5 million shares, valued at nearly $90 million. This marks a significant increase from approximately 549,000 shares at the end of 2025. The filing also indicates that these holdings represent securities positions under UBS's investment management authority for reporting purposes and may not be entirely held with UBS's own funds, potentially including client account holdings. The article notes that while this allocation remains limited relative to UBS's overall assets under management, it reflects the firm's ongoing efforts to expand Bitcoin-related exposure through compliant securities instruments.
