Musk v. OpenAI Trial Begins with $134 Billion Claim Over Nonprofit Conversion
A nine-person jury in Oakland will decide whether OpenAI's transformation from charitable research lab to $852 billion commercial giant constitutes legal looting—or legitimate corporate evolution.
A federal jury began hearing testimony this week in Elon Musk’s lawsuit against OpenAI, where the billionaire is seeking up to $134 billion for what he calls the systematic dismantling of a nonprofit he founded and funded. The trial, which opened Monday with jury selection and proceeded to opening arguments Tuesday, has been narrowed from 26 original claims to just two: unjust enrichment and breach of charitable trust.
The Core Allegations
Musk’s case rests on the claim that he was “assiduously manipulated” and “deceived” by Sam Altman, Greg Brockman, and OpenAI into funding what he believed was a nonprofit research laboratory focused on developing safe artificial intelligence outside the profit motives of Google and Facebook. “I came up with the idea, the name, recruited the key people, taught them everything I know, provided all the initial funding,” Musk testified, according to CNBC.
Between December 2015 and May 2017, Musk contributed approximately $38 million to what was structured as a 501(c)(3) charitable organisation. The company’s subsequent transformation—creating a capped-profit subsidiary in 2019 and accepting Microsoft’s multi-billion-dollar investment—forms the heart of Musk’s legal challenge. “If we make it OK to loot a charity, the entire foundation of charitable giving in America will be destroyed,” he told the jury, per Reuters.
“We are here because Mr. Musk didn’t get his way at OpenAI. That’s what happened. He quit, saying they would fail for sure. But my clients had the nerve to go on and succeed without him.”

OpenAI’s Defense Strategy
OpenAI’s legal team, led by attorney William Savitt, frames the lawsuit as sour grapes from a departed founder who bet against the company’s future. In opening statements, Savitt argued that Musk left OpenAI in 2018 predicting failure, only to watch the organisation he abandoned become one of the most valuable private companies in technology. The company has called the lawsuit “a baseless and jealous bid to derail a competitor,” according to CNBC.
The defense will need to justify the structural transformation that occurred after Musk’s departure. OpenAI created a hybrid structure in 2019—maintaining a nonprofit parent while establishing a for-profit subsidiary with capped returns for investors. Microsoft’s investment exceeded $13 billion since that restructuring, funding the compute infrastructure required to train models like GPT-4 and ChatGPT.
Internal Documents Surface
Musk’s attorneys have introduced diary entries from OpenAI co-founder Greg Brockman that appear to show internal doubts about the corporate evolution. “I cannot believe that we committed to non-profit if three months later we’re doing b-corp then it was a lie,” Brockman wrote in a 2017 entry, according to The Next Web. The entry predates the formal for-profit subsidiary creation by two years, suggesting discussions about commercial structures began while the organisation was still operating as a pure nonprofit.
Financial Pressures and IPO Timing
The trial arrives as OpenAI faces mounting financial pressure despite its astronomical valuation. Internal projections point to $14 billion in losses for 2026 alone, with cumulative losses expected to exceed $44 billion before the company achieves profitability. Those economics make an eventual IPO nearly inevitable—and any legal cloud over the legitimacy of the nonprofit-to-commercial conversion creates substantial uncertainty for potential public investors.
The timing also intersects with Musk’s own capital markets plans. SpaceX is preparing what analysts expect to be a record-breaking public offering, and a protracted legal battle with OpenAI creates complexity for both companies’ investor presentations.
Legal Precedent at Stake
Judge Yvonne Gonzalez Rogers has structured the trial in two phases: a liability determination followed by a remedies phase if wrongdoing is found. The jury’s verdict will be advisory only, with Gonzalez Rogers making the final decision in both phases. That structure gives the judge flexibility to consider the broader implications of any ruling on nonprofit corporate governance.
Charitable trust law typically requires that donated assets be used for their stated purpose in perpetuity. When nonprofits convert to commercial entities, state attorneys general usually review whether the transformation serves the original charitable mission. OpenAI’s 2019 restructuring maintained a nonprofit parent, arguing this preserved mission alignment while enabling capital formation. Musk’s breach of charitable trust claim challenges whether that structure satisfies fiduciary obligations to original donors.
The outcome will establish boundaries for how deep-tech startups can evolve their corporate structures as capital requirements scale. If Musk prevails, other AI labs that began as research nonprofits—Anthropic started with similar nonprofit ambitions before pivoting—may face constraints on commercial transitions. A ruling for OpenAI would validate the hybrid nonprofit-parent-with-for-profit-subsidiary model as legally defensible.
Analysis from MIT Technology Review suggests the case tests whether courts will recognise enforceable obligations to a company’s original mission beyond what Nonprofit Law strictly requires. Musk’s $134 billion damages calculation appears based on unjust enrichment theory—essentially claiming he should receive equity proportional to his founding contributions had OpenAI been structured commercially from inception.
What to Watch
The trial is expected to run two to three weeks, with a decision likely by mid-May. Key variables include whether the jury (and ultimately Judge Gonzalez Rogers) accepts Musk’s characterisation of the 2019 restructuring as a breach of charitable trust, or OpenAI’s framing that the hybrid model preserved mission commitments while enabling necessary capital formation.
Internal communications beyond Brockman’s diary entry will be critical—any evidence showing OpenAI leadership privately acknowledged the commercial pivot contradicted founding commitments would strengthen Musk’s case. Conversely, documentation of genuine efforts to maintain safety-focused governance within the new structure supports OpenAI’s defense.
Beyond the immediate parties, the trial sets precedent for AI Governance structures. If courts impose strict limits on nonprofit-to-commercial evolution, capital-intensive AI research may face pressure to launch as commercial entities from day one—eliminating the public-interest credibility that nonprofit origins provide. A ruling for OpenAI removes that constraint but raises questions about whether any founding commitments truly bind once capital requirements change.
