Summary

The closely watched trial between Elon Musk and OpenAI CEO Sam Altman began in federal court in Oakland on April 29, 2026, with Musk seeking $150 billion in damages and a reversal of OpenAI's restructuring. Musk alleges Altman stole a nonprofit, comparing OpenAI's shift to a for-profit entity to a major heist. OpenAI's counsel, William Savitt, countered that Musk sued out of "sour grapes" after failing to gain absolute control of the company himself in 2017. The month-long trial, presided over by Judge Yvonne Gonzalez Rogers, will hear from various tech executives and former board members. Dueling emails from 2015-2017 were presented, showing Musk's evolving views on OpenAI's for-profit structure. Microsoft's $13 billion investment in 2019 was also scrutinized, with Musk's attorney accusing Microsoft of complicity, while Microsoft's counsel denied attempts to control OpenAI. The judge issued a social media ban for both parties due to Musk's prior online comments.

Key takeaway

For investors evaluating AI startups, this trial underscores the critical importance of clearly defined organizational structures and founder agreements from inception. Ambiguities regarding nonprofit versus for-profit status, equity distribution, and control can lead to protracted, high-stakes litigation, potentially impacting company valuation and stability. Scrutinize founding documents and early communications to assess potential future legal risks.
