US District Judge Yvonne Gonzalez Rogers denied requests from both companies to dismiss the case on Thursday. The ruling allows Musk to present his claims to a jury.
Musk helped launch OpenAI in 2015 as a nonprofit research organization. He contributed $38 million in seed funding through an intermediary before leaving the company’s board in 2018.
The lawsuit centers on Musk’s claim that OpenAI broke promises to operate as a charitable trust. He argues his donations came with two conditions: that OpenAI would remain open source and maintain its nonprofit status.
OpenAI is now valued at $500 billion after announcing restructuring plans in October 2024. The company gave Microsoft a 27% ownership stake while keeping the nonprofit arm in control of for-profit operations.
Email Evidence Survives Dismissal
Judge Gonzalez Rogers pointed to internal communications from 2017 as key evidence. In September that year, board member Shivon Zilis told Musk that co-founder Greg Brockman wanted to continue with the nonprofit structure.
Two months later, Brockman wrote in a private note: “cannot say that we are committed to the non-profit. don’t want to say that we’re committed. if three months later we’re doing b-corp then it was a lie.”
The judge wrote that while the evidence is unclear, Musk has presented enough to proceed. She rejected OpenAI’s argument that using an intermediary to donate stripped Musk of legal standing.
Marc Toberoff, Musk’s lawyer, said the ruling confirms substantial evidence that OpenAI’s leadership made false assurances about its charitable mission. OpenAI called the lawsuit baseless and part of Musk’s ongoing harassment pattern.
Microsoft Role Under Scrutiny
The judge found Musk presented enough evidence that Microsoft may have helped OpenAI breach its responsibilities to donors. She said a jury must decide if Microsoft had actual knowledge of wrongdoing.
The court did reject one claim against Microsoft. Musk argued the software company unjustly enriched itself at his expense, but the judge said he lacked the proper relationship with Microsoft to make that claim.
Microsoft has not commented on the ruling. The company has invested billions in OpenAI and integrated its technology across products.
OpenAI sent a letter to investors and banking partners on Thursday warning about the upcoming trial. The company said it expects Musk to make “deliberately outlandish, attention-grabbing claims” during proceedings.
The AI company told investors it has strong defenses and feels confident about winning. OpenAI said the case is worth no more than the $38 million Musk donated, though that is not guaranteed.
Musk filed the lawsuit in August 2024 in US District Court in Northern California. He claims he was manipulated and deceived as OpenAI explored converting to a for-profit entity.
The billionaire departed OpenAI’s board in 2018 and later founded his own AI company, xAI, in 2023. xAI has become one of OpenAI’s main rivals in the artificial intelligence market.
Last year, OpenAI rejected Musk’s unsolicited bid to acquire the nonprofit’s assets for $97.4 billion. CEO Sam Altman has called Musk’s legal actions a weaponization of the court system to slow down a competitor.
