Private journal entries from OpenAI’s president, read in open court, reveal a leader wrestling with a billion-dollar ambition years before the company’s pivot to a for-profit model.
Private journal entries from OpenAI’s president, read in open court, reveal a leader wrestling with a billion-dollar ambition years before the company’s pivot to a for-profit model.

The legal battle between Elon Musk and the leadership of OpenAI took a dramatic turn as private 2017 journal entries from co-founder and President Greg Brockman were entered into evidence, exposing a deep-seated conflict between the company’s non-profit mission and his own financial ambitions. The revelations provide a contentious narrative backbone to Musk’s central claim that he was deceived into funding a charity that was later converted into a for-profit enterprise now valued in the tens of billions.
"Well, it's very painful," Brockman testified when asked how it felt to have his private writings read in court, according to courtroom reports. While admitting the exposure was difficult, he added, "there's nothing in there that I'm ashamed of." The journal was kept as he processed critical decisions for the burgeoning artificial intelligence lab.
The most striking entries date back to 2017, long before OpenAI’s formal restructuring. In an August entry, Brockman asked himself, "Financially, what will take me to $1B?" A month later, wrestling with the implications of a potential pivot, he wrote that to "steal the non-profit from him [Musk]... to convert to a b-corp without him... that’d be pretty morally bankrupt."
These entries are the emotional core of a lawsuit that could reshape the AI industry. Musk alleges OpenAI’s leaders committed a breach of contract by abandoning the original non-profit agreement, seeking to unwind the company’s for-profit arm and its multi-billion-dollar partnership with Microsoft. For investors, the trial exposes the governance risks and personality-driven conflicts at the heart of a company central to Microsoft's (MSFT) AI strategy and market valuation.
The journal entries provide a timeline of the internal struggle at OpenAI. Musk’s legal team argues they are proof of a premeditated plan to sideline him and monetize the technology he helped fund. OpenAI’s counsel counters that the entries show a leadership team grappling honestly with existential questions about how to fund the immense computing power needed for artificial general intelligence, a mission they claim Musk himself understood would require vast capital.
Testimony from Shivon Zilis, a senior executive at several of Musk's companies and the mother of several of his children, added another layer of complexity. Zilis testified about early discussions involving Musk himself regarding for-profit structures, including one that would have made OpenAI a subsidiary of Tesla. This suggests the for-profit path was not a secret plot but a contentious, long-debated topic among the founders.
The diary is just one of several pieces of private correspondence that have painted a portrait of a company rife with ambition and political maneuvering. Leaked texts from Zilis to Musk revealed her asking if she should stay "close and friendly" with OpenAI "to keep info flowing," noting that the "trust game is about to get tricky."
Further turmoil was revealed in texts between CEO Sam Altman and then-CTO Mira Murati during Altman's brief ouster in 2023. After Altman asked for an update, Murati’s stark reply that things were "directionally very bad" has become a viral snapshot of the company’s chaotic governance.
The trial’s revelations could have significant market implications. While OpenAI is a private company, its stability is crucial for Microsoft, which has committed over $13 billion and integrated OpenAI’s models across its product suite. Any outcome that disrupts OpenAI's leadership or corporate structure could damage Microsoft's AI narrative, which has helped propel its stock to a more than $3 trillion valuation. The drama also provides a window of opportunity for competitors like Google (GOOGL) and Musk's own xAI to question the stability and mission-alignment of the current market leader.
