OpenAI president’s private journal entries read aloud in Elon Musk lawsuit

A private journal kept by OpenAI President Greg Brockman is now courtroom evidence, and its contents are exactly as awkward as you’d expect when someone’s personal reflections about getting rich collide with a company that was founded to benefit humanity.

The diary entries, which span roughly a decade of internal deliberations at OpenAI, were read publicly during the ongoing trial between Elon Musk and the AI company. They detail Brockman’s thinking about transitioning OpenAI from a non-profit to a for-profit entity, including estimates of a pathway to $1B in personal net worth amid a $30B company valuation.

What the journal actually says

The entries were originally submitted as sealed evidence in October 2025 before being publicly unsealed in January 2026. They cover years of internal debate at OpenAI about the organization’s structure, its financial trajectory, and the tensions that come with trying to build world-changing technology while also, apparently, doing some back-of-the-napkin math on personal wealth.

One notable entry addresses Elon Musk’s departure from OpenAI. Brockman’s writing suggests that Musk’s exit was perceived internally as a morale hit, partly because of concerns about his pursuit of artificial general intelligence, or AGI.

Brockman has faced direct questioning during the trial about Musk’s central allegation, that OpenAI effectively committed “theft” of its own founding mission by pivoting toward profit. The journal entries give Musk’s legal team something they rarely get in corporate litigation: a contemporaneous, first-person account of the internal thought process behind that pivot, written by one of the people who made it happen.

The broader Musk vs. OpenAI saga

Musk co-founded OpenAI in 2015 as a non-profit research lab. He departed in 2018, and the relationship has been deteriorating ever since. The lawsuit alleges that OpenAI’s leadership, particularly CEO Sam Altman, betrayed the organization’s original charter by converting it into what is now one of the most valuable private companies in AI.

Musk’s argument boils down to a simple claim: he donated money and lent his name to a non-profit mission, and the people running it turned it into a money machine for themselves. OpenAI’s defense has generally been that the capped-profit structure it adopted was necessary to attract the investment capital required to compete in the AI arms race.

The discovery process in this trial has also surfaced a detail with implications well beyond OpenAI’s corporate structure. All AI prompts used internally are logged and can potentially be accessed during litigation. If your team is running strategic discussions through an AI chatbot, those conversations may not be as ephemeral as you think.

Why the crypto world is watching

This trial doesn’t involve cryptocurrency directly, but the connections are hard to ignore. Sam Altman, OpenAI’s CEO, is also a co-founder of Worldcoin, the crypto project that distributes WLD tokens using iris-scanning biometric verification. Worldcoin already faces scrutiny from data protection authorities in multiple countries over its iris-scanning methods.

That said, WLD has not experienced any notable price reaction tied to the trial developments over the past 30 days. Markets, at least for now, appear to be treating the lawsuit as an OpenAI-specific event rather than something that contaminates the broader Altman ecosystem.

Every Slack message, every journal entry, every AI prompt log is a potential exhibit. For crypto firms operating in regulatory gray zones, the OpenAI trial is a case study in what discovery looks like when the stakes are measured in billions.
