Elon Musk´s legal team has filed a motion for an injunction against OpenAI, aiming to halt its transition to a for-profit entity. The ongoing lawsuit between Musk and OpenAI, submitted in a California federal court, accuses OpenAI’s leadership and its key partner Microsoft of antitrust violations, unethical financial practices, and governance failures. Musk’s attorneys argue that OpenAI’s shift betrays its nonprofit mission and undermines fair competition in the AI sector.
The filing highlights exclusivity agreements, self-dealing allegations, and financial mismanagement as key concerns. Musk’s team contends that these practices harm competitors, including his AI venture, xAI, and threaten the broader AI ecosystem by consolidating market power inappropriately.
Basically, Musk is asking the court to stop OpenAI from becoming a fully for-profit company and to halt some of its business practices, like making agreements with investors that prevent them from supporting competitors like Musk’s xAI.

Allegations of Investor Bias and Market Manipulation
A major focus of the legal motion is OpenAI’s alleged use of exclusivity clauses to restrict investor support for rival companies. Musk’s attorneys claim these agreements violate the Sherman Act and stifle competition.
The filing provides examples of how these restrictions impacted xAI, noting that at least one major investor backed out of supporting Musk’s venture after participating in OpenAI’s funding round.
“OpenAI’s path from a non-profit to for-profit behemoth is replete with per se anticompetitive practices, flagrant breaches of its charitable mission, and rampant self-dealing,” the filing asserts. It further claims that OpenAI’s actions create an uneven playing field, making it nearly impossible for emerging competitors to secure critical funding.
Musk´s legal team argues that these practices harm not only xAI but also the public interest by concentrating AI capabilities within a narrow set of stakeholders.

Governance Failures and Ethical Questions
Musk’s lawyers allege that OpenAI’s leadership, particularly CEO Sam Altman, has engaged in self-dealing by prioritizing financial partnerships that benefit companies in which he holds personal stakes. A prominent example is OpenAI’s selection of Stripe as its payment processor, despite Altman’s ties to the company.
“An injunction to preserve what is left of OpenAI’s non-profit character, free from self-dealing, is the only appropriate remedy. If not, the OpenAI promised to Musk and the public will be long gone by the time the Court reaches the merits,” the filing states.
The document also raises concerns about OpenAI’s financial management, noting that its annual expenditures exceed $5 billion. Musk’s attorneys warn that this spending, combined with heavy reliance on external funding, could lead to insolvency, jeopardizing its ability to compensate damages if the lawsuit is successful.
Microsoft’s Role in OpenAI’s Operations
Microsoft, which has invested $13 billion in OpenAI, is another central target of Musk’s legal challenge. The motion alleges that Microsoft used its influence to align OpenAI’s operations with its own strategic goals, creating conflicts of interest and restricting fair competition.
The filing highlights the role of Dee Templeton, a Microsoft executive who briefly served as a non-voting observer on OpenAI’s board. Musk’s attorneys argue that Templeton’s position allowed Microsoft to access sensitive business strategies, leading to decisions that unfairly benefited its interests.
“The very reason Microsoft obtained its board seat—through its representative Dee Templeton—was to coordinate business decisions with OpenAI,” the filing states. “This relationship violates fundamental principles of fair competition, creating an environment where Microsoft and OpenAI’s market dominance remains unchecked.”

From Nonprofit Mission to For-Profit Ambitions
The lawsuit brings into sharp focus OpenAI’s transformation from a nonprofit into a capped-profit entity in 2019 and now toward becoming a fully for-profit corporation. Originally designed to limit investor payouts while reinvesting surplus revenue into the nonprofit, the capped-profit model was intended to balance funding needs with equitable AI development.
Critics like Musk argue that these changes dilute OpenAI’s original mission to democratize artificial intelligence. “No objective observer can look at OpenAI today and say it bears any resemblance whatsoever to what it promised to be,” Musk’s filing asserts.
The lawsuit further contends that this shift increases the risk of concentrating AI innovation within a select group of private stakeholders, reducing transparency and accountability.
xAI’s Growing Competitive Presence
Amid the legal battle, Musk’s xAI is positioning itself as a direct competitor to OpenAI in the generative AI space. The company recently raised about $6 billion, leveraging proprietary data from Tesla’s autonomous driving systems and X’s conversational platforms to refine its AI models.
xAI’s flagship offering, Grok, competes directly with OpenAI’s ChatGPT. Supported by the Colossus supercomputer—one of the world’s largest AI computing infrastructures—Grok promises enhanced speed and contextual accuracy. Musk’s ability to align xAI’s development with his other ventures gives the company a unique advantage in the competitive AI landscape.
Governance Disputes and Leadership Tensions
The legal motion also sheds light on longstanding disputes within OpenAI’s leadership. Emails released as part of the proceedings reveal the various differences between Musk and co-founders like Altman in the early stages of OpenAI. While Musk advocated for centralized control to ensure strict adherence to OpenAI’s mission, Altman and others favored a collaborative governance model.
These disagreements culminated in Musk’s resignation from OpenAI’s board in 2018, marking a turning point for the organization. The fallout from this departure continues to shape OpenAI’s direction, as evidenced by its growing reliance on external partnerships and commercial funding.
