Fast summary
Start here
- OpenAI President Greg Brockman testified for two days, using personal journal entries to describe Elon Musk’s aggressive bid for control in 2017.
- The testimony details an August 2017 meeting where Musk reportedly became angry and stormed out after being denied total authority over the organization.
- The evidence is being used in an ongoing legal battle where Musk's lawyers claim Sam Altman and Brockman 'stole a charity' to form a for-profit entity.

What happened
OpenAI President Greg Brockman provided a detailed account of the events leading to Elon Musk’s departure from the company, describing a late August 2017 meeting where Musk allegedly attempted to seize control. Testifying over two days, Brockman referenced entries from a personal journal to illustrate what he described as a 'pitched battle' between Musk and the other co-founders over the future direction of the then-nonprofit research lab.
What's new in this update
The disclosure of Brockman’s private journal entries offers new insight into the interpersonal dynamics at a critical juncture for OpenAI. Brockman recounted an incident where, upon being told the founders would not grant him full control, Musk allegedly 'stormed around the table' and became aggressive. Brockman testified that he feared physical confrontation during the encounter, after which Musk took back a painting intended as a gift and effectively ended his regular financial contributions to the operating budget.
Key details
The conflict centered on how OpenAI would transition into a for-profit entity to fund the pursuit of Artificial General Intelligence (AGI). Musk had gifted several co-founders Tesla Model 3 vehicles, which Brockman characterized as an attempt to win support for Musk's vision over Sam Altman's. While Musk left the board within six months of the 2017 meeting, he continued to pay for office space the company shared with Neuralink until 2020.
Background and context
This testimony is part of the broader legal battle initiated by Elon Musk against Sam Altman and Greg Brockman. Musk’s legal team is attempting to show that the founders abandoned the organization's original charitable mission. Conversely, OpenAI’s legal team is presenting evidence that Musk had similar intentions for commercialization and control prior to his departure, suggesting the current dispute is over who ultimately led that transition.
What to watch next
The trial is expected to continue with additional witnesses and evidence regarding the 2017-2018 period. While Brockman has concluded his testimony, the court has yet to hear from Sam Altman. Legal observers are watching closely to see if the jury will be permitted to see more recent communications, such as a text message Musk allegedly sent to Brockman warning that he and Altman would become 'the most hated men in America.'
Why it matters
This testimony provides firsthand evidence in a high-stakes trial that could redefine the history, ownership, and mission of one of the world's most influential AI labs.
