Key Takeaways
- 13 of top 15 institutional shareholders added to MSTR positions in Q1 2026.
- Combined holdings up 27%, measured in share quantity at fixed 5/15/26 price.
- Defiance ETFs entered fresh at $511M: new entrant, not an existing holder adding.
- Capital International added $1,921M; UBS added $35M: same cohort, different conviction.
The 13-of-15 figure includes Defiance ETFs, which held no MSTR at the end of 2025 and entered with $511M in a single quarter, making it a new institutional entrant rather than an existing holder adding conviction, a meaningful distinction the framing does not draw. Remove Defiance and the cohort is 12 existing holders adding, one holding flat, and one reducing. That still represents the majority of the top 15 adding deliberately to an existing position, which is the stronger claim and the more accurate one.
