Musk Escalates OpenAI Legal Battle with $150B Claim and Leadership Ouster Demand

Key Takeaways

• Elon Musk has revised his legal action against OpenAI, stipulating that any awarded damages should be directed to OpenAI’s nonprofit division rather than to him personally
• The billionaire entrepreneur is pursuing damages exceeding $150 billion from both OpenAI and its primary backer, Microsoft
• The amended complaint calls for Sam Altman’s removal from OpenAI’s nonprofit board and the dismissal of Greg Brockman from his officer position
• The federal trial is scheduled to commence with jury selection on April 27 at the Oakland, California courthouse
• OpenAI has dismissed the legal action as “a harassment campaign driven by ego, jealousy and a desire to slow down a competitor”

On Tuesday, Elon Musk submitted a revised version of his legal complaint against OpenAI, specifying that any monetary awards should be channeled to the organization’s charitable division instead of his personal accounts. The updated filing also requests judicial intervention to strip CEO Sam Altman and President Greg Brockman of their leadership positions.

The dispute traces back to Musk’s initial lawsuit filed in 2024. His central allegation contends that OpenAI misled him into contributing $38 million under false pretenses that the organization would maintain its nonprofit status. Since then, OpenAI has undergone a corporate transformation, establishing a nonprofit entity that maintains a 26% ownership interest in its commercial operations.

The origins of the partnership date to 2015, when Musk and Altman were among the founding members of OpenAI. Musk departed the organization in 2018 following an unsuccessful attempt to integrate it with Tesla. By 2023, he had established xAI, a rival artificial intelligence venture that created the Grok conversational AI system.

The financial stakes in Musk’s legal challenge are substantial. He’s now pursuing more than $150 billion in combined damages from OpenAI and Microsoft, the latter being OpenAI’s principal financial supporter. This represents an increase from the $134 billion maximum his legal team requested in documents filed this past January.

Marc Toberoff, representing Musk in the case, emphasized that his client “is not seeking a single dollar for himself.” According to Toberoff, the litigation aims to restore misappropriated assets to their rightful charitable purpose while ensuring accountability for those allegedly responsible.

What Musk Is Asking the Court to Do

The revised legal filing requests that the court compel Altman and Brockman to surrender any equity holdings or monetary gains they’ve accumulated to OpenAI’s charitable entity. Additionally, Musk’s attorneys are asking the court to mandate that OpenAI return to functioning as a legitimate nonprofit organization.

OpenAI responded swiftly to the amended complaint. Through a statement posted on X, the company characterized the lawsuit as “nothing more than a harassment campaign that is driven by ego, jealousy and a desire to slow down a competitor.” When contacted for comment, Microsoft representatives declined to provide a statement.

The Road to Trial

The legal proceedings are moving forward with jury selection scheduled to commence April 27 at a federal courthouse in Oakland, California.

Just one day before Musk’s amended filing, OpenAI dispatched correspondence to the attorneys general of both California and Delaware. The communication accused Musk of deliberately disseminating misleading information designed to undermine OpenAI’s credibility in advance of the upcoming trial. OpenAI further alleged that Musk has been working in concert with Meta CEO Mark Zuckerberg on coordinated efforts targeting the company.

OpenAI’s market valuation currently stands at $852 billion, with the company preparing for a public offering expected later this year. Meanwhile, SpaceX’s acquisition of xAI in February—a transaction that valued the merged companies at $1.25 trillion—has been followed by confidential SEC filings that could pave the way for what analysts predict would be a historically significant IPO.
