Greg Brockman Says Elon Musk Threatened Physical Violence in 2017 OpenAI Meeting

Context The testimony came during the second week of a month‑long trial in Oakland, where Musk is suing OpenAI to reverse its transition from a non‑profit to a for‑profit model. The case pits Musk against OpenAI’s chief executive Sam Altman and other founders, highlighting a feud that began when Musk left the organization he helped launch in 2015.

Key Facts Brockman recounted that after he rejected Musk’s request for greater control, Musk’s demeanor changed sharply. “I actually thought he was going to hit me,” Brockman said, describing his fear of a physical assault. The confrontation ended with Musk announcing he would stop providing the financial support he had supplied since OpenAI’s inception. Brockman also testified that Musk was fully aware of the company’s plan to add a for‑profit arm, a move designed to attract billions in investor capital. Text messages from August 2017 between OpenAI co‑founder Ilya Sutskever and Brockman show Musk’s team probing how much leverage they could gain, hinting at the pressure to accept “massively unfavourable terms.”

What It Means If the jury finds Musk’s actions constituted intimidation, the ruling could set a precedent for how founders and investors negotiate control in high‑growth tech ventures. The case also underscores the growing tension between early AI pioneers and the massive commercial stakes now tied to models like ChatGPT. The next witness, former board member Shivon Zilis—who has personal ties to Musk—will likely address the broader conflict of interest and governance issues.

Watch for the jury’s verdict and any settlement talks that could reshape OpenAI’s ownership structure.
