Mark Zuckerberg
Medium
Mark Zuckerberg’s net worth is overwhelmingly tied to Meta Platforms stock. Meta’s 2026 proxy discloses 341.8M Class B shares beneficially controlled by Zuckerberg; at the access-date META price of $611.21, those shares are worth about $208.9B. After cross-checking Bloomberg and Forbes real-time billionaire estimates and adding minor visible real-estate signals, a base range of $209B–$218B is most supportable.
