The Genesis of OpenAI and its Mission
Elon Musk co-founded OpenAI in 2015 alongside Sam Altman and others as a non-profit organization focused on AI research. The story of their early collaboration and eventual divergence is detailed in The Secret History of Elon Musk, Sam Altman, and OpenAI. Initially, OpenAI aimed to develop artificial intelligence for the benefit of all humanity, operating under a non-profit structure to counteract the dominance of large corporations in the nascent AI field.
Musk himself invested $38 million into the organization during its early years, contributing to its charitable mission, as reported by Semafor. Both Musk and Altman shared a profound concern that AI could spiral out of control, a sentiment also documented by Semafor. Musk publicly warned about the risks of the technology in its early stages, describing AI as "dangerous" and "full of risks" in 2015, according to Semafor.

Elon Musk, an early investor and co-founder, publicly warned about the inherent dangers and risks of AI technology as early as 2015.
The Divergence and Musk's Departure
By 2018, however, cracks began to show in OpenAI’s unified front. Musk left OpenAI’s board, citing a potential conflict of interest with Tesla’s developing AI efforts, a detail highlighted in Semafor’s reporting. Beyond this, internal conflicts intensified. Musk sought greater control over OpenAI and even proposed merging it with Tesla, but OpenAI rejected his terms, as further explained by Semafor.
OpenAI leadership argued that Musk had recognized the need for a for-profit structure as early as 2017 to fund the enormous development costs associated with advanced AI research, a claim supported by an OpenAI Newsroom tweet. OpenAI later published emails which they claim support the idea that Musk backed plans for a for-profit entity, visible in another tweet from OpenAI Newsroom. Musk expressed frustrations in emails from 2018, stating "OpenAI is on a secure path to failure compared to Google" and "Guys, I’ve had enough," according to the OpenAI Newsroom.

OpenAI then transitioned into a for-profit subsidiary, OpenAI LP, to secure necessary funding for its ambitious projects, a move detailed by Semafor. Microsoft became a premier partner and investor starting in 2019, as also reported by Semafor.
The Legal Battle Unfolds
In 2024, Musk filed a lawsuit against OpenAI, alleging that the company, Sam Altman, and Microsoft betrayed its founding non-profit mission, information that can be found in a Semafor article. He claims that he was manipulated and deceived regarding OpenAI’s non-profit direction, as also stated by Semafor. OpenAI denies these accusations, labeling them as a "harassment campaign driven by ego, jealousy, and a desire to slow down a competitor," a statement made via OpenAI Newsroom on X.

The launch of ChatGPT in 2022 propelled OpenAI to global recognition, significantly increasing its influence and reach in the AI landscape.
The trial itself began in April 2026 at the U.S. District Court for the Northern District of California in Oakland, presided over by Judge Yvonne Gonzalez Rogers, as reported by derStandard.at. The core of Musk’s argument centers on the idea that OpenAI’s shift to a for-profit model, particularly after Microsoft’s substantial investments and integrations, constitutes a breach of the initial agreement to develop open-source AI for public benefit, a point elaborated on by Semafor. OpenAI’s valuation has soared, with plans for a potential IPO, according to Semafor.
Musk had previously attempted to acquire OpenAI in 2025 for $97.4 billion, an offer which was rejected by the company, as announced by OpenAI Newsroom on X. His own AI company, xAI, founded in 2023, now directly competes with OpenAI’s offerings through its chatbot, Grok, as shown in the court listener document.

Elon Musk’s xAI company introduced its own chatbot, Grok, in 2023, positioning it as a direct competitor to OpenAI’s diverse offerings.
During the proceedings, Musk testified that he did not read the "fine print" regarding OpenAI’s transformation into a for-profit entity, and that he was reassured by Altman and others that OpenAI would remain a non-profit, as reported by The Verge. However, internal emails suggest Musk himself had previously sought a for-profit structure for OpenAI and even envisioned himself leading it and controlling its board, as indicated by OpenAI Newsroom on X. He also admitted he had used OpenAI to train his own xAI models, according to The Verge.
The legal strategy on Musk’s side has seen some adjustments. His claims have been significantly reduced, with fraud allegations withdrawn to streamline the case, as detailed in the court listener document. The judge also disallowed testimony about existential risks posed by AI, stating that the trial was not about the safety risks of artificial intelligence, a point highlighted by The Verge.

A judge dismissed one of the lawsuits filed by Musk and xAI on February 24, 2026, as reported by OpenAI Newsroom on X. OpenAI had also requested the court on February 2, 2026, to stop Musk’s alleged destruction of evidence, according to the same OpenAI Newsroom tweet. The court also rejected Musk’s attempt to access OpenAI’s proprietary source code on January 22, 2026, as also reported by OpenAI Newsroom.

Conclusion
The conflict between Elon Musk and OpenAI reflects a fundamental struggle over the direction and control of artificial intelligence. What began as a collaborative effort to develop AI for the common good has devolved into a bitter legal and public relations battle, underscoring the immense financial and intellectual stakes involved. The outcome of this trial will not only impact the two powerful entities but could also set precedents for the future governance and commercialization of AI. Regardless of the legal verdict, the underlying questions about who benefits from advanced AI and who controls its development will continue to shape the industry for years to come.
