Elon Musk and Sam Altman are in loggerheads once again, and this time, a court trial grabs the headlines. Musk has alleged that OpenAI strayed from its original nonprofit mission. He claims he backed OpenAI on that promise, but it later shifted toward a profit-led model with close ties to Microsoft, raising questions about control and intent.
The complaint focuses on Musk's allegation that OpenAI violated early pledges by abandoning its original nonprofit objective and moving toward a profit-driven model, raising broader worries about governance over potent AI systems.
A nine-member jury has been selected in Oakland as the case officially moves forward. The judge clarified the trial will focus on facts and promises, not technical AI complexity, setting the stage for a closely watched legal battle.
Elon Musk alleges that OpenAI abandoned its founding nonprofit mission and pivoted toward a profit-driven model. He claims the shift happened without transparency, turning a public-interest initiative into a commercial powerhouse.
The lawsuit frames the dispute as a betrayal between former partners. Musk claims he was misled into funding OpenAI under a nonprofit promise, which later changed into a revenue-focused structure tied to investors.
In a post on X, Elon Musk wrote that “Sam Altman and Greg Brockman stole a charity,” claiming OpenAI was turned into a profit-driven venture. He argued the case raises a broader question on whether a nonprofit can be converted for private gain, warning it could set a precedent affecting charitable institutions across the United States.
Scam Altman and Greg Stockman stole a charity. Full stop.

Greg got tens of billions of stock for himself and Scam got dozens of OpenAI side deals with a piece of the action for himself, Y Combinator style. After this lawsuit, Scam will also be awarded tens of billions in stock… https://t.co/R27ZeG9nNR
OpenAI has strongly denied wrongdoing, arguing Musk left the company voluntarily and later turned against it. The company claims the lawsuit reflects rivalry and regret rather than genuine concerns about mission or ethics.
A US judge dismissed Musk’s fraud allegations before trial. The case now centres on breach of charitable trust and unjust enrichment, significantly narrowing the legal scope.
In contrast to OpenAI’s stance, which denies wrongdoing and casts the lawsuit as driven by rivalry after Musk’s exit, a post on X by Déborah backs Musk. It questions OpenAI’s transparency, defends his intent, and ends with a blunt line: “Elon Musk must win.”
To those who pit Sam Altman and Elon Musk against each other like a billionaire feud, look, do your own research.

When have you ever seen Elon Musk use his money to buy a yacht, a paradise island, or engage in extravagant spending?
Even the money from this lawsuit, if he wins,…
Musk is seeking damages exceeding $130 billion, with any payout directed to OpenAI’s nonprofit arm. He has also named Microsoft as a defendant, alleging its deep financial partnership enabled OpenAI’s shift to a profit-driven model, a claim the company denies.
Beyond seeking damages, Elon Musk is pushing for sweeping structural changes at OpenAI. He wants Sam Altman and Greg Brockman removed from leadership and the organisation restored to its original nonprofit framework through court intervention.
Musk also says he contributed about $38 million in early funding, based on assurances that OpenAI would remain nonprofit, a commitment he now argues was later broken.
Shivon Zilis, a former OpenAI board member and mother of four of Elon Musk’s children, may testify, with OpenAI alleging she shared internal information with Musk. The trial comes at a sensitive moment, as Musk shifts from seeking personal damages to directing any financial recovery to OpenAI’s charitable arm instead.
The trial could feature testimony from major industry figures, including Musk, Altman, and Microsoft CEO Satya Nadella. Internal documents, emails, and early records may play a crucial role in shaping the verdict.
Referencing a post by Frances Wang on X, many original claims were dropped ahead of trial, with the court focusing on two key issues: “breach of uncharitable trust” and “unjust enrichment.” Elon Musk has also sued Microsoft, alleging it aided actions tied to OpenAI’s shift.

Judge YGR explaining to jurors the 2 claims they’ll be hearing:
1. BREACH OF UNCHARITABLE TRUST
2. UNJUST ENRICHMENT
Musk also suing Microsoft for aiding & abetting on first claim above.
Experts say the outcome may influence how AI companies operate globally. A ruling against OpenAI could affect leadership, governance, and the control and deployment of advanced AI systems.
Opening statements are underway, with evidence likely to be presented over the weeks before deliberation. The advisory jury will weigh facts, but the final decision will ultimately rest with the judge.
Internal documents pull back the curtain on how OpenAI transformed from a nonprofit lab into a company valued above $850 billion, exposing internal dynamics and decision-making. The trial could derail IPO ambitions and fuel public skepticism, as Elon Musk alleges Sam Altman and Microsoft steered it away from its original mission.
Cross-examinations have not started, as proceedings remain in the opening phase with jury selection and arguments underway. Elon Musk maintains that OpenAI betrayed its nonprofit mission, while Sam Altman denies wrongdoing, calling the lawsuit baseless. Witness testimony is expected next, followed by cross-examination.
Elon Musk co-founded OpenAI in 2015 as a nonprofit focused on benefiting humanity. He left in 2018 amid strategic differences. In 2019, OpenAI introduced a capped-profit model and deepened ties with Microsoft. Musk claims this shift broke original commitments, while Sam Altman argues the changes were necessary to fund advanced AI development.

Elon Musk told the court the lawsuit is simple: OpenAI’s leadership turned a nonprofit into a profit machine. He argued such a shift undermines charitable trust and could set a dangerous precedent for misuse of nonprofit structures.
Musk testified first, outlining OpenAI’s founding vision and his role. He positioned himself as central to early funding and recruitment, setting the tone for a trial expected to examine governance, contracts, and intent behind OpenAI’s structural evolution.
Musk argued OpenAI abandoned its original goal of benefiting humanity. He said leadership pivoted toward commercial success, contradicting early commitments that shaped his financial and strategic involvement in the organization’s early years.
Amid the high-stakes courtroom battle, Elon Musk escalated his public stance with a blunt social media post targeting OpenAI’s shift. He accused the company of abandoning its nonprofit roots, reinforcing his legal argument in real time.

OpenAI’s legal team claimed Musk’s lawsuit stems from competition with his AI venture xAI. They argued he only raised objections after OpenAI’s commercial success, framing the case as strategic interference rather than a principled dispute.
A controversial post circulating on X dragged Sam Altman into a heated narrative, with users amplifying claims about his background while tying it to criticism of OpenAI’s direction. This comes as Judge Yvonne Gonzalez Rogers cautioned both Elon Musk and Altman against public commentary, warning such exchanges could influence jurors and disrupt proceedings.
The post read, “This is what happens when you make someone CEO whose religion and culture have prioritized profit over morality for thousands of years,” sparking outrage and raising concerns over the tone of online discourse.

On the stand, Musk said he played a key role in funding OpenAI and attracting talent. He emphasized his network and influence, claiming he helped bring in top researchers and establish credibility during the company’s early phase.
Musk described founding OpenAI as a counterweight to Google’s AI dominance. He referenced early concerns about concentration of power in big tech and positioned OpenAI as a necessary alternative at the time.
Musk’s legal demands include removing Sam Altman and Greg Brockman from leadership roles. He argued their decisions reshaped OpenAI in ways that conflict with its founding agreement and original nonprofit commitments.
OpenAI’s defense argued no binding commitment required the company to remain nonprofit. Lawyers said structural evolution was discussed internally and aligned with long-term goals, rejecting claims of deception or contractual violations.
Proceedings revealed friction between Musk and OpenAI leaders. Testimony and filings highlighted disagreements over direction, leadership influence, and strategy, turning the case into both a legal and personal confrontation.
Despite its stakes, the trial has centered heavily on personal disputes and financial motivations. Observers note limited discussion on broader AI safety issues, with narratives dominated by conflict between powerful tech figures.
Musk warned that allowing OpenAI’s transition would legitimize misuse of charitable entities. He framed the lawsuit as a broader test case that could influence how nonprofits operate across industries in the future.
The trial unfolds as OpenAI targets a massive valuation and potential IPO. Legal uncertainty around governance and structure could impact investor confidence and reshape the company’s future trajectory.
The case is expected to feature major tech leaders, including Microsoft CEO Satya Nadella. Their testimonies could provide insight into partnerships, internal decisions, and the evolution of OpenAI’s business model.
Musk returned to the stand and doubled down on his central argument, saying OpenAI’s shift to profit ‘betrayed’ its founding charter and donor intent, reinforcing his push for structural reversal and leadership accountability.
Musk’s legal team signalled that Jared Birchall, who manages his finances and oversees parts of xAI, would be called next, suggesting a deeper dive into funding flows and financial structuring behind OpenAI’s transformation.
Elon Musk wrapped up Day 2 by warning OpenAI’s shift could erode trust in nonprofits, framing the case as a broader accountability issue. Court adjourned after tense exchanges, with both sides holding ground as the lawsuit moves into a decisive phase that could reshape AI governance globally.
With Musk’s testimony done, attention shifts to financial records, internal communications, and upcoming witnesses expected to clarify OpenAI’s structural decisions. Their testimonies could prove pivotal in determining whether the company’s transition aligned with its founding mission or marked a fundamental departure.
