Elon Musk's Lawsuit Against OpenAI Begins Trial

A federal trial opened in Oakland, California, on claims by Elon Musk that OpenAI breached its founding mission as a nonprofit organization. The case, filed in March 2024, names OpenAI CEO Sam Altman, co-founder Greg Brockman, and investor Microsoft as defendants, with allegations including breach of charitable trust and unjust enrichment.

Musk seeks billions in damages to be directed to OpenAI's nonprofit arm and the removal of Altman as CEO. According to court filings cited in source materials, Musk donated $38 million to OpenAI between 2015 and 2018 during its operation as a nonprofit.

He departed the organization in 2018 following disagreements on its direction, leadership, and safety protocols.

Court exhibits from the trial, as detailed in source [3], include 2015 emails between Musk and Altman discussing OpenAI's initial structure. " Emails also reference Musk's offer of Tesla sensor data and potential employee equity in Tesla or SpaceX. Altman proposed in correspondence a governance board including himself, Musk, Bill Gates, Pierre Omidyar, and Dustin Moskovitz, with technology owned by a foundation for public benefit.

Musk committed $100 million initially and emphasized in emails the need for a safety board to oversee releases of potentially dangerous AI. OpenAI's articles of incorporation, filed on December 8, 2015, established it as a nonprofit. Additional exhibits indicate Nvidia CEO Jensen Huang provided an early supercomputer, and Altman sought support from Y Combinator for facilities and operations.

During testimony on the first day, Musk stated, "It's actually very simple. It's not okay to steal a charity... If it's okay to loot a charity, the entire foundation of charitable giving will be destroyed," according to source [2]. U.S. District Judge Yvonne Gonzalez Rogers, presiding over the trial, warned Musk, Altman, and Brockman against using social media to influence proceedings.

" Musk's attorney, Steven Molo, told jurors that OpenAI would not exist without Musk and referenced a 2015 meeting with then-President Barack Obama about unregulated AI. OpenAI's attorney, William Savitt, stated in opening remarks that Musk attempted to merge OpenAI with Tesla and left after his bid to become CEO was refused.

Exhibits from source [3] show early tensions, including emails from Brockman and Ilya Sutskever expressing concerns about Musk's proposed level of control. Musk highlighted in emails a preference for a nonprofit structure where revenue would build reserves rather than generate profits.

Altman is scheduled to testify, and the trial may reveal additional internal communications, such as emails involving Ilya Sutskever and texts with Meta CEO Mark Zuckerberg, based on exhibits listed in source [3]. Amid the proceedings, Altman posted on X on May 5 announcing a party for the release of GPT-5.5, stating, "Elon can come if he wants.

The world needs more love," according to sources [4] and [5]. Registration for the event closed within hours, with Altman noting plans for larger celebrations in the future.

OpenAI launched ChatGPT in 2022, contributing to growth in commercial AI applications. Musk founded xAI in 2023, releasing its chatbot Grok. OpenAI's position, as stated in court documents, is that Musk was aware of the 2018 shift to include a commercial arm and departed after failing to secure control.

The case centers on interpretations of OpenAI's founding as a nonprofit in 2015, with Musk as a key donor and contributor to its mission statement. A verdict is expected in late May. No publicly released evidence from the source bundle documents independent verification of the parties' motivations beyond their own statements and exhibits.
