Why super-investors own MSTR
Ownership of MSTR within this cohort remains thin and largely unchanged — just two holders as of 2026Q1, down from a brief peak of two the prior quarter before settling back. Bill Miller, the more committed of the pair, holds MSTR at 1.7% of his portfolio — the highest concentration in the cohort — and added to his position this quarter. Joel Greenblatt carries a much larger absolute dollar value ($152M) but at a minimal 0.1% portfolio weight, suggesting a peripheral rather than high-conviction stance. No new entrants emerged this quarter. With owner count oscillating between one and two over the past two years and no exits or new starts, broader cohort interest appears stable at a low baseline rather than building.
