As of Q2 2026, 24 SEC-registered investment managers reported holding MUB (ISHARES TR) in their latest 13F filings, with a combined reported value of $13.02B across 121.12M shares. That is +8.6% by share count (+9.60M shares) versus the previous quarter, while reported value moved +10.0%. Ownership is concentrated: the five largest holders account for 77.7% of reported value and the top ten for 96.8%.

Compared with the prior quarter, 2 opened new positions, 14 added to existing stakes, 6 trimmed. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
