Our Take
Brockman's evasive testimony and damaging journal entries about flipping to for-profit make him OpenAI's weakest link in court.
Why it matters
The Musk v. Altman trial could reshape how AI nonprofits handle commercial transitions, with Brockman's own words providing the strongest evidence against OpenAI's narrative.

Brockman's journal undermines OpenAI's defense
Greg Brockman took the stand in Elon Musk's lawsuit against OpenAI with unusual procedures (cross-examination before direct) and delivered testimony that may have strengthened Musk's case. The OpenAI president's own 2017 journal entries, recovered from text files on his computer, revealed internal debates about converting from nonprofit to for-profit status.
Key journal quotes included: "maybe we should just flip to a for-profit. making money for us sounds great and all" and "cannot say we are committed to the non-profit. don't wanna say we're committed. if three months later we're doing a b-corp it is a lie." Another entry stated converting without Musk "would be pretty morally bankrupt."
Brockman's current stake in OpenAI's for-profit arm is worth approximately $30 billion (per court testimony). When asked why he hadn't donated $29 billion back to the nonprofit if $1 billion was sufficient, Brockman deflected with unresponsive answers about the nonprofit's stake value rather than addressing the question directly.
Financial conflicts complicate the narrative
The testimony revealed multiple financial entanglements between Brockman and companies doing business with OpenAI, including Cerebras, CoreWeave, Stripe, and Helion Energy. Brockman also holds a 1 percent stake in Sam Altman's family office, a compensation arrangement that Musk apparently discovered only through a 2017 email from his assistant.
Brockman's version of OpenAI's founding positioned it as primarily his and Altman's initiative, with Musk appearing as a distant figure who became involved only after the core team was assembled. This directly contradicts Musk's narrative that he was a co-founder addressing competitive threats from Google.
Cross-examination reveals preparation gaps
Brockman's courtroom performance demonstrated how technical leaders can struggle under legal scrutiny. His pedantic corrections of minor word omissions and evasive responses to direct questions about his wealth created an impression of untrustworthiness that may overshadow his direct testimony.
The case highlights risks when internal communications surface in litigation. Brockman's informal journal entries about profit motives and organizational changes became primary evidence against OpenAI's charitable mission narrative.
