# Public Benefit Corporation A for-profit corporate structure that legally requires directors to balance stockholder financial interests with a stated public benefit and the interests of those materially affected by the corporation's conduct. Available in Delaware and most U.S. states. Unlike a traditional C-corp, a PBC's charter names a specific public benefit purpose; unlike a nonprofit, it can raise equity capital, go public, and distribute profits. The PBC structure matters for the vault because it's the legal form [[OpenAI]] chose for its October 2025 for-profit conversion. OpenAI Group PBC names "the development and maintenance of advanced AI for the long-term benefit of humanity" as its stated public benefit. Critics argue this is a fig leaf: the PBC structure preserves the language of mission while enabling the $852B valuation, unlimited investor returns, and IPO path that a genuine nonprofit structure would have prevented. The practical difference between a PBC and a C-corp is minimal. Directors must "balance" stakeholder interests, but the standard for what constitutes adequate balancing is extremely deferential — no PBC director has ever been held liable for failing to serve the public benefit. The structure gives management rhetorical cover for mission-oriented decisions but no binding constraint against pure profit-maximization. [[Anthropic]] is also structured as a PBC, with a Long-Term Benefit Trust as an additional governance layer. ## See Also - [[OpenAI Investors]] — the conversion that enabled the $852B valuation
