Equity comp at Anthropic

• Anthropic is a Public Benefit Corporation (PBC), a corporate structure that requires the board to balance making money for shareholders against pursuing the company's stated public benefit (here, AI safety research). For employees, this does not change federal tax on your equity. What it can change is timing: when the company decides whether to organize an employee share-sale event (an industry term: 'tender offer'), the board has to weigh financial returns against the benefit purpose, which can delay or shrink those events compared to a typical for-profit company.
