Musk, Altman to Testify in OpenAI Lawsuit as Trial Looms

San Francisco federal court will host a courtroom showdown that could decide the direction of one of the world’s most influential AI labs. OpenAI, the nonprofit behind ChatGPT, has sued Elon Musk, alleging that he exaggerated his role in the organization’s success and disparaged the work of its scientists. In response, Musk’s legal team has filed a countersuit that challenges OpenAI’s governance and its claims of public benefit.

Both Musk and OpenAI co‑founder Sam Altman are slated to testify for more than two hours each. The two will be joined by a line‑up of high‑profile witnesses that reads like a Silicon Valley roll call. Mira Brockman, who helped build OpenAI’s early models, is scheduled for a 2½‑hour session that could stretch even longer. Microsoft CEO Satya Nadella will appear for roughly an hour, underscoring the tech giant’s stake in the outcome. Former OpenAI chief scientist Ilya Sutskever has a 30‑minute slot, while Shivon Zilis—Musk’s longtime associate and mother of four of his children—will also speak for half an hour. Zilis, dubbed an “Elon whisperer” in Altman’s deposition, may provide insight into the personal dynamics that fueled the dispute.

The trial could run for four weeks, with every witness entering through the courthouse’s front doors, a detail that judge Gonzalez Rogers said will keep the process transparent. Courtroom photographers are expected to capture the moment when tech insiders file in, a visual that will likely dominate headlines for days.

Beyond the personalities, the case spotlights the shifting competitive landscape of artificial intelligence. OpenAI faces “unprecedented competition” from Anthropic, which recently achieved a $1 trillion valuation, and from Google’s AI arm. Reuters notes that Musk’s own AI startup, xAI, trails far behind OpenAI in user adoption, a point that may influence the jury’s perception of each side’s market relevance.

During his deposition, Musk was asked whether he still regarded artificial general intelligence as an “existential threat,” a question that highlights a philosophical rift. OpenAI’s lawyers suggested that Musk’s for‑profit model conflicts with the nonprofit’s public‑benefit charter. Musk answered cautiously, acknowledging risk without conceding a contradiction between his business interests and the broader safety concerns.

Legal analysts say the outcome could have far‑reaching implications for how AI research is funded and governed. If OpenAI prevails, the nonprofit may reinforce its public‑benefit status and press for stricter oversight of for‑profit AI ventures. Conversely, a victory for Musk could embolden private companies to pursue aggressive AI development with fewer regulatory constraints.

Both camps appear prepared for a protracted battle. Altman’s team has hinted at calling additional industry leaders as witnesses, while Musk’s lawyers are expected to lean on expert testimony that questions the practical impact of OpenAI’s nonprofit structure. As the trial date approaches, the tech world watches closely, aware that the verdict could set a precedent for the balance between innovation, profit, and public good in the AI era.
