Why super-investors own ZD
Interest in ZD within this cohort is minimal and only recently emerging. Bill Miller initiated a new position in 2026Q1 — the first new entrant in at least eight quarters — allocating roughly 0.7% of his portfolio, or approximately $3M. Joel Greenblatt holds a similarly sized stake at around $3M, though it registers as a rounding-zero concentration in his broader book. Combined cohort exposure sits at just $6M across two holders, making ZD a peripheral name rather than a conviction play. The single new entry from Miller nudges the owner count from one to two, but the overall trajectory remains too thin to signal a meaningful shift in cohort sentiment.
