Altman rejects accusation of ‘stealing a charity’
During testimony in federal court, firmly denied Musk’s allegation that OpenAI leaders had effectively “stolen a charity.”
“It feels difficult to even wrap my head around that framing,” Altman told the court.
He added: “It does not fit with my concept of the words ‘stealing a charity’ to look at what is happening here.”
Altman argued that still stands to benefit significantly from the company’s future success.
“As OpenAI continues to do well, the nonprofit will do even better,” he said.
OpenAI says company structure evolved over time
Altman also disputed suggestions that OpenAI was fundamentally Musk’s creation.
According to Altman, the organisation explored multiple corporate structures during its early years, including both nonprofit and for-profit possibilities.
“At the time we had no conception we would someday have profits or revenue,” Altman testified.
The remarks form part of OpenAI’s broader defence that the company’s evolution reflected changing technological and financial realities rather than a betrayal of its founding principles.
OpenAI claims Musk wanted control

“I was extremely uncomfortable” with Musk’s demand for control, Altman said.
OpenAI contends that stems partly from frustration over missing out on the massive financial upside generated by the AI boom.
OpenAI chairman questions Musk takeover bid
OpenAI chairman Bret Taylor also testified on Tuesday, revealing that OpenAI received a formal takeover proposal in February 2025 from a consortium led by Musk’s AI company xAI.
Taylor said the proposal appeared contradictory given Musk’s legal claims about protecting OpenAI’s nonprofit mission.
“I was surprised,” Taylor testified.
He continued: “This proposal was to acquire this non-profit by a group of for-profit investors, which felt contradictory to the spirit of the lawsuit.”
Musk seeks damages and leadership removal
Musk is seeking roughly $150 billion in damages from OpenAI and Microsoft, which has invested heavily in OpenAI’s infrastructure and AI development.

Former OpenAI chief scientist Ilya Sutskever testified that he spent nearly a year collecting evidence suggesting Altman showed a “consistent pattern of lying.”

Other witnesses have included former OpenAI technology chief Mira Murati and former OpenAI board member Shivon Zilis.
Musk warns about AI leadership risks
Musk, who testified earlier in the proceedings, framed the dispute as a matter of public safety and AI governance.
“If you have someone who is not trustworthy in charge of AI, I think that’s a very big danger for the whole world,” Musk told the court.
He also maintained that OpenAI originated from his vision before shifting away from its nonprofit roots.
According to Musk, Altman had assured him that OpenAI would remain a nonprofit organisation even as discussions about commercialisation emerged.
Trial could shape OpenAI’s future
The case is being overseen by US District Judge Yvonne Gonzalez Rogers.
Testimony is expected to conclude this week, with jurors potentially beginning deliberations by May 18 on whether OpenAI executives are legally liable.
Any remedies or penalties would ultimately be determined by the judge.
