Musk's Tesla Gambit: Trial Testimony Reframes the OpenAI Lawsuit as a Power Play

7. Musk's Tesla Gambit: Trial Testimony Reframes the OpenAI Lawsuit as a Power Play

Shivon Zilis, a former OpenAI board member and mother of four of Elon Musk's children, testified in the ongoing Musk v. OpenAI trial that Musk offered Sam Altman a seat on Tesla's board of directors as an inducement to bring OpenAI under Tesla's corporate umbrella. The testimony emerged during proceedings in May 2026. Zilis, who also holds a senior role at Neuralink, was positioned as a credible insider witness given her simultaneous proximity to both Musk's orbit and OpenAI's early governance. No dollar figure for a proposed deal was disclosed in the testimony.

The revelation reframes the entire lawsuit. Musk's public argument has centered on OpenAI betraying its nonprofit mission by drifting toward commercial interests and Microsoft's influence. That framing positioned him as a principled objector. Zilis's testimony suggests a different read: Musk wanted OpenAI's assets and talent inside a company he controls, and the lawsuit followed after that effort failed. For Microsoft, which holds a reported $13 billion investment in OpenAI, this testimony strengthens the counter-narrative that Musk's legal campaign is competitive displacement dressed as ethics. It also puts pressure on the judge to weigh Musk's standing as a disinterested plaintiff.

The broader pattern worth tracking is how this trial is functioning as forced discovery on OpenAI's early governance. Each week of testimony surfaces internal communications and personal negotiations that OpenAI would never have disclosed voluntarily. Whatever the verdict, the trial is building a public record of how the organization's power dynamics actually worked between 2015 and 2018. Anthropic, xAI, and any future nonprofit-to-commercial AI conversion will be reading that record closely.
