What is Majority Shareholder?
A majority shareholder is an individual, institution, or entity that owns more than 50% of a company's outstanding voting shares, granting them effective control over all shareholder votes. This control extends to board elections, approval of major corporate transactions such as mergers and acquisitions, amendments to the corporate charter, and dividend policy decisions. Majority shareholders can typically block or approve any resolution that requires a simple shareholder majority. When a single entity holds majority control, minority shareholder protections — such as appraisal rights and fiduciary duty obligations owed by controlling shareholders — become especially important governance safeguards.
Example
Elon Musk became the majority shareholder of Twitter (now X Corp.) in October 2022 after completing his $44 billion acquisition of the company. As 100% owner of the private company, Musk had unconstrained authority to replace the board, restructure management, change Twitter's policies, and take the company private — all without shareholder consent.
