Jury Deliberates Whether OpenAI’s $850B Pivot Violated Founding Promises

A federal jury in Oakland began deliberations Monday on whether OpenAI’s transformation from nonprofit to an $850 billion public benefit corporation violated charitable trust and fiduciary duties owed to co-founder Elon Musk, who donated $38 million between 2015 and 2017.

The verdict could establish binding precedent for how AI labs navigate the tension between mission-driven founding commitments and the capital demands of building frontier models. OpenAI’s October 2025 recapitalization — which left its nonprofit foundation holding just 26% equity while converting the company to a for-profit structure — enabled Microsoft to secure a $135 billion stake from $13.8 billion in cumulative investments, according to CNBC. Musk’s attorneys argue this transformation betrayed founding agreements to develop AI safely for humanity’s benefit, open-sourced where practical.

The Core Claims

Musk seeks up to $134 billion in disgorgement damages and court-ordered unwinding of the 2025 recapitalization, per CNBC. His legal team also wants Judge Yvonne Gonzalez Rogers to remove CEO Sam Altman and President Greg Brockman from leadership roles, alleging they orchestrated the shift to prioritise commercial returns over safety mandates.

The trial, which concluded closing arguments on May 14, exposed internal documents suggesting OpenAI’s leadership questioned the nonprofit framing from the start. A 2017 journal entry by Brockman — presented as trial evidence by TheNextWeb — described the nonprofit structure as “a lie.” A January 2023 memo projected Microsoft would earn a $92 billion return on its OpenAI investment, underscoring the commercial logic driving governance decisions.

Competing Narratives

In closing arguments, Musk’s lead attorney Steven Molo framed the case as theft of a public trust. “A non-profit devoted to the safe development of artificial intelligence, open sourced as practical, for the benefit of humanity. You know, we’re supposed to buy that,” he told jurors, according to the Bangkok Post.

OpenAI’s defense portrayed Musk as a power-seeking founder who lost interest once he couldn’t control the organisation. “He never cared about the nonprofit structure… What he cared about was winning,” attorney Sarah Eddy argued, per Benzinga. She pointed to testimony from Shivon Zilis, an early OpenAI board member and mother of three of Musk’s children, who contradicted key elements of his account.

The credibility battle between Musk and Altman became central to the trial’s final week. Musk’s concurrent leadership of xAI — a for-profit AI competitor valued at $50 billion — complicated his positioning as a defender of nonprofit AI research. OpenAI’s attorneys argued his true motive was commercial rivalry, not mission fidelity.

Financial Stakes and Governance Precedent

The numbers illustrate OpenAI’s rapid evolution from research lab to commercial infrastructure. ChatGPT reached 700 million weekly active users by September 2025, according to TechTimes, while the company projects $14 billion in losses for 2026 as it scales compute infrastructure and model development. Microsoft’s stake — now approximately 27% on an as-converted diluted basis — positions it as the primary beneficiary of OpenAI’s shift to for-profit operations.

The nine-person advisory jury’s verdict carries no binding legal force — Judge Gonzalez Rogers retains final authority over liability determinations, CNBC noted. However, a finding that OpenAI violated fiduciary duties would strengthen Musk’s position in the remedies phase, where the court will determine whether to unwind the recapitalization or impose financial penalties.

Industry-Wide Implications

The case arrives as philanthropic watchdog groups oppose the recapitalization, arguing it sets dangerous precedent for how nonprofits with AI research mandates can pivot to commercial structures. If the court finds OpenAI’s conversion unlawful, Venture Capital-backed AI labs may face heightened scrutiny over governance arrangements that promise public benefit while enabling investor returns.

A verdict against OpenAI would complicate its path to a potential IPO and constrain governance flexibility for Anthropic, Mistral AI, and other labs that began with nonprofit or public benefit charters. Conversely, a ruling in OpenAI’s favor would signal that founding mission statements carry limited legal weight once board composition changes and capital structures evolve.

What to Watch

The jury is expected to reach a verdict within the next week, with Judge Gonzalez Rogers then scheduling a remedies phase to determine penalties if liability is found. OpenAI has signalled it will appeal any adverse ruling, potentially extending litigation into 2027. Regulatory filings for GPT-5 deployment and any announcements of additional funding rounds will test how investor confidence responds to the legal uncertainty. Separately, monitor whether Microsoft adjusts its governance role or stake sizing in advance of a final ruling — the company has stayed publicly silent throughout the trial despite being named as a co-defendant in earlier filings.
