Microsoft CEO to Testify in Elon Musk's Lawsuit Against OpenAI

Microsoft CEO Satya Nadella is expected to testify on Monday in Elon Musk's lawsuit against OpenAI, explaining emails that revealed how his company funded OpenAI's shift from a philanthropic organization to a for-profit AI giant. Nadella's testimony will precede that of OpenAI boss Sam Altman, whose questioning is likely to take place on Tuesday or Wednesday.

The trial has laid bare the internal strife within a circle of elite Silicon Valley engineers, investors, and executives in the years leading up to the launch of the ChatGPT chatbot in 2022. Musk accuses OpenAI of betraying its original nonprofit mission and misappropriating his founding donations totaling $38 million to build an empire valued at over $850 billion.

OpenAI counters that Musk left voluntarily after failing to seize majority control and has since become the company's direct competitor through his own AI venture, xAI. An advisory jury is expected to reach a verdict on any actual wrongdoing by the week of May 18, after which Judge Yvonne Gonzalez Rogers will make the final ruling on both liability and remedies.

The trial has already heard gripping testimony, including from co-founder Greg Brockman, whose stake in OpenAI is valued at $30 billion. Musk's lawyers have seized on Brockman's 2017 diary entries to portray him as a calculating opportunist.

The outcome of the trial will have significant implications for OpenAI's potential initial public offering, which could be jeopardized if the court rules in favor of Musk. The court will resume hearing on Tuesday, with the advisory jury expected to reach a verdict by the week of May 18.
