A private journal kept by OpenAI President Greg Brockman has become courtroom evidence in the ongoing trial between Elon Musk and OpenAI, with the entries describing internal deliberations about the company’s shift from a non-profit structure toward a for-profit model.
The diary entries were submitted as sealed evidence in October 2025 and were publicly unsealed in January 2026. They cover roughly a decade of internal debate at OpenAI, including discussions of organizational structure, financial trajectory, and tensions between building advanced technology and personal wealth considerations.
According to the publicly read entries, Brockman’s writing includes thinking about transitioning OpenAI from a non-profit to a for-profit entity. The material also reportedly contains estimates related to a potential pathway to $1 billion in personal net worth alongside a $30 billion company valuation.
One entry addresses Elon Musk’s departure from OpenAI. Brockman’s writing suggests Musk’s exit was viewed internally as a morale hit, including concerns tied to Musk’s pursuit of artificial general intelligence (AGI).
During the trial, Brockman has faced questioning connected to Musk’s allegation that OpenAI effectively “stole” its founding mission by pivoting toward profit. The journal entries provide Musk’s legal team with what the article describes as a contemporaneous, first-person account of internal thinking behind that pivot.
Musk co-founded OpenAI in 2015 as a non-profit research lab and left in 2018. The lawsuit alleges that OpenAI’s leadership, including CEO Sam Altman, betrayed the organization’s original charter by converting it into one of the most valuable private companies in AI.
Musk’s position is that he donated money and lent his name to a non-profit mission, but that leadership turned the effort into a profit-driven enterprise. OpenAI’s defense has generally been that the capped-profit structure it adopted was necessary to attract investment capital to compete in the AI industry.
The discovery process in the trial has also surfaced details with broader implications. The article states that all AI prompts used internally are logged and can potentially be accessed during litigation. That raises the possibility that internal strategic discussions conducted through AI tools may not be as temporary as teams might assume.
While the trial does not involve cryptocurrency directly, the article notes connections through Sam Altman. Altman is described as a co-founder of Worldcoin, a crypto project that distributes WLD tokens using iris-scanning biometric verification. Worldcoin has faced scrutiny from data protection authorities in multiple countries regarding its iris-scanning methods.
Despite these connections, the article says WLD has not shown any notable price reaction tied to the trial developments over the past 30 days, with markets treating the lawsuit as an OpenAI-specific event rather than something that spreads to the broader Altman ecosystem.
The article frames the case as an example of how discovery can work when the stakes are measured in billions, noting that Slack messages, journal entries, and AI prompt logs can all become potential exhibits. For crypto firms operating in regulatory gray zones, it describes the OpenAI trial as a case study in the evidentiary risks of using AI and maintaining internal records.
