Musk vs. Altman: The Day the "Founding Myth" of the AI Industry Crumbles in Court

In April 2026, a trial began in the federal court of Oakland, California, that could potentially shape the future of the AI industry. The dispute is between Elon Musk and Sam Altman, the leader of OpenAI. Once united by the same ideals to establish OpenAI, the two are now clashing head-on over "who owns AI."

This trial cannot be dismissed as merely a feud between billionaires because OpenAI is at the heart of the current generative AI boom. Since the advent of ChatGPT, AI has infiltrated search, education, software development, creative industries, finance, healthcare, and administration, shaking both corporate value and social systems. The founding of this central company is being re-examined in court.

Musk's argument is clear. OpenAI began in 2015 as a non-profit organization with the mission to "develop artificial intelligence for the benefit of all humanity." Musk provided initial funding and lent his reputation and credibility. Despite this, OpenAI later pursued a major partnership with Microsoft, transforming into a profit-driven organization. Musk's side claims this was a betrayal of the founding promise.

On the other hand, OpenAI presents a completely different narrative. AI development requires enormous computational resources, talent, and data center investments. The ideal of non-profit alone cannot withstand competition from Google, Meta, Anthropic, xAI, and Chinese entities. OpenAI argues that commercialization and becoming a Public Benefit Corporation were not to "abandon the mission" but rather "a realistic vessel to achieve the mission." They further counter that Musk himself understood the necessity of a profit division in the past.

The essence of this conflict is the clash between "ideals" and "capital." OpenAI was originally created to avoid a future where AI is monopolized by a few giant corporations or governments. Ironically, developing cutting-edge AI requires capital on par with giant corporations. Training AI models requires computational resources on the scale of hundreds of billions of yen, and attracting top researchers necessitates high salaries. As a result, in order to protect ideals, they moved closer to capital, and the closer they moved to capital, the more their ideals were questioned.

The focus of this trial is not just the magnitude of the money involved. Musk's side is seeking massive damages and a review of OpenAI's management structure, which could impact the positions of Altman and Greg Brockman. There is also speculation that key figures in the AI industry, including Microsoft's CEO Satya Nadella, might be involved. Internal documents and testimonies revealed in court will serve as materials not only for OpenAI's history but also for how Silicon Valley has transformed ideals into capital.

Reactions on social media are not neatly divided. Rather, multiple layers of distrust overlap.

The most prominent criticism is that "OpenAI is no longer open, contrary to its name." In AI-related communities like Reddit, disappointment is repeatedly expressed that OpenAI has strayed from its non-profit, open ideals to become a closed giant AI company. Users who had high expectations for the early OpenAI view its current corporate value, relationship with Microsoft, and IPO speculation with skepticism.

Support for Musk is also not monolithic. On X, some view Musk as "the person trying to protect OpenAI's original ideals," while others hold the view that "he just wants to create a favorable competitive environment for his own AI company, xAI." Musk, who leads X, Tesla, SpaceX, and xAI, wields significant influence, and many users question whether his criticism of OpenAI is based solely on public interest or also includes competitive interests.

Opinions on Altman are also divided. Supporters appreciate his management skills in growing OpenAI into a global AI company and see him as a leader who understands the realities of AI development. Critics suspect that he created a massive profit-driven company after initially gaining trust under a non-profit banner. On social media, Altman is seen both as a "realist of the AI era" and as a "symbol of commercializing ideals."

Moreover, there are many reactions that perceive the trial itself as "worrisome no matter who wins." If Musk wins, OpenAI's current structure and investment plans could be shaken, creating significant uncertainty in AI companies' funding models. If OpenAI wins, it might appear that there are low legal hurdles for organizations that start with non-profit ideals to later transform into giant profit-driven companies. In other words, neither victory fully resolves the trust issues in the AI industry.

In this regard, the trial overlaps with concerns about the AI bubble. Generative AI companies are amassing huge amounts of funding and making massive investments in data center construction, semiconductor procurement, and cloud contracts. However, it is still unclear whether the actual monetization and social benefits justify these investments. The courtroom battle over OpenAI has brought to the surface multiple issues that the AI industry faces, such as "ideals," "profitability," "safety," "monopoly," and "transparency."

Particularly important is the governance of AI companies. Traditional tech companies could be explained through the relationships between founders, investors, boards of directors, and shareholders. However, AI companies often claim impacts and safety on a human scale. This raises the question of whether they should be operated solely on the logic of a regular corporation. OpenAI adopted a structure combining a non-profit foundation and a Public Benefit Corporation as an answer to this. However, this trial questions whether that structure truly ensures public interest.

For investors, this trial cannot be ignored. If the trial affects OpenAI's organizational restructuring or its relationship with Microsoft, it could ripple through AI-related stocks, cloud companies, semiconductor companies, and data center operators. Although OpenAI is a private company, it already influences the overall expectations of the AI market. If governance concerns rise, it could dampen valuations across the AI sector.

However, it is dangerous to simplify this trial into a "good vs. evil" narrative. Many can sympathize with Musk's claim that "OpenAI should return to its original mission." On the other hand, Musk himself leads a competing company, xAI, and owns X, a massive information distribution infrastructure. OpenAI's argument that "cutting-edge AI cannot be created without commercialization" is compelling, but the more commercialization progresses, the more concerns about transparency and public interest grow.

Ultimately, what this trial confronts is not just an issue for OpenAI. The modern AI industry accelerates with private capital while speaking of public interest, advances through market competition while advocating safety, and encloses models and data as trade secrets while being called for transparency. OpenAI most symbolically bears this contradiction, and Musk, one of its founders, is attacking it from the outside.

The frustration spreading on social media is not merely a voyeuristic interest in a celebrity trial. Users are acutely aware that AI is changing their work, creativity, education, and information environment. Meanwhile, the decision-making of companies creating AI is almost invisible. Who decides the direction of AI? Is growth prioritized over safety? Was the ideal of non-profit just a narrative for fundraising? These questions are projected onto the Musk vs. Altman trial.

Regardless of the outcome of this trial, the AI industry will not return to the same place as before. If OpenAI wins, the industry might more strongly justify "the path of companies that start with ideals and later commercialize." If Musk wins, the legal responsibility for AI companies' organizational design and founding promises will become heavier. In any case, AI companies will be more than ever required to explain their mission, capital structure, conflicts of interest, and transparency.

The AI boom following ChatGPT has been told as a story of technology. However, this trial is turning it into a story of institutions. Who owns AI, who profits, who bears the risks, and who oversees it? The courtroom battle between Musk and Altman goes beyond their relationship, questioning the very social contract of the AI era.

More important than who wins is that this trial has made it insufficient for the AI industry to simply say "trust us." If AI is to be for humanity, its governance must also be explainable to humanity. The OpenAI trial is posing this obvious question at the heart of the world's most watched AI company.
