OpenAI co-founder and president Greg Brockman discloses in federal court that his stake in the company is now worth nearly $30 billion, according to multiple outlets. Brockman says he is among the largest individual stakeholders in OpenAI, the organization behind ChatGPT. Several reports add that the testimony also touches on Brockman’s financial relationships tied to CEO Sam Altman, with lawyers questioning whether financial incentives could affect Brockman’s independence. One outlet reports that questioning comes from a lawyer associated with Elon Musk, who co-founded OpenAI and is suing the company, alleging it improperly shifted to a for-profit structure. Other outlets describe Brockman defending the value of his stake and the work behind it, framing his disclosure as part of the court proceedings rather than a standalone announcement. Across the reports, the central point is Brockman’s stated valuation of his holdings and the role of that disclosure within a broader legal dispute involving OpenAI, its leadership, and Musk’s claims about the company’s governance and structure.
