Shivon Zilis, who has four children with Elon Musk, testified against him in his legal battle with OpenAI’s Sam Altman. Zilis once worked closely with Musk but is now speaking out in court as a witness.
This is a dramatic turn in the high-profile lawsuit where Musk claims Altman betrayed their original vision for OpenAI. The case has drawn attention because it involves some of the biggest names in AI fighting over the future of artificial intelligence.
From Inner Circle to Courtroom
Zilis was once considered one of Musk’s most trusted advisors and worked with him on various projects including Neuralink, his brain-computer interface company. She had unprecedented access to Musk’s business decisions and personal life, making her testimony particularly damaging.
The lawsuit centers on Musk’s claim that OpenAI abandoned its nonprofit mission when it partnered with Microsoft. Musk helped found OpenAI in 2015 but left the board in 2018. Now he’s asking courts to force the company back to its original open-source approach.
Zilis’s willingness to testify against Musk shows how fractured relationships have become in Silicon Valley’s AI race. Her testimony could provide insider details about Musk’s motivations and business practices that few people would know.
What’s Next
The trial continues with more witnesses expected to testify about the early days of OpenAI. Musk’s legal team will likely try to discredit Zilis’s testimony, while Altman’s lawyers use her insider knowledge to defend OpenAI’s evolution into a for-profit company.
