Musk, a co-founder of OpenAI, is suing the company, Chief Executive Sam Altman, President Greg Brockman and major investor Microsoft, alleging they abandoned OpenAI’s original mission of developing artificial intelligence for the benefit of humanity and instead turned it into a commercial enterprise focused on profit.

“If we make it okay to loot a charity, the entire foundation of charitable giving in America will be destroyed,” Musk told the court on the first day of trial. “That’s my concern.”Musk is seeking $150 billion in damages from OpenAI and Microsoft, with the proceeds directed to OpenAI’s charitable arm. He is also asking the court to require OpenAI to return to nonprofit control and to remove Altman and Brockman from leadership roles, while seeking Altman’s removal from the board.

The lawsuit includes claims of breach of charitable trust and unjust enrichment and could have significant implications for OpenAI’s governance as the company explores a potential initial public offering that Reuters has previously reported could value it near $1 trillion.

OpenAI lawyer Bill Savitt told jurors during opening arguments that Musk had originally supported the idea of turning OpenAI into a for-profit structure and only sued after failing to gain control of the company and later launching his own rival artificial intelligence venture, xAI.Savitt said Musk wanted “the keys to the kingdom” and pursued litigation only after OpenAI rejected his ambitions to lead the company.

“What he cares about is Elon Musk being on top,” Savitt said. “We are here because Mr Musk didn’t get his way.”OpenAI’s legal team argued that its decision in March 2019 to establish a for-profit entity was necessary to secure the computing resources and talent needed to compete with rivals such as Google’s DeepMind artificial intelligence division.

Musk’s lawyer Steven Molo rejected that argument, saying OpenAI’s leadership shifted focus once major investors, including Microsoft, entered the picture.“It wasn’t a vehicle for people to get rich,” Molo said.Before jurors entered the courtroom, U.S. District Judge Yvonne Gonzalez Rogers warned Musk over his social media activity after OpenAI lawyers raised concerns about his posts on X, where he referred to Altman as “Scam Altman” and accused him of stealing a charity.

Rogers said she was reluctant to impose a gag order but urged Musk to avoid using social media to influence matters outside the courtroom.Musk agreed to reduce his online commentary, as did Altman. Both are expected to testify, along with Microsoft Chief Executive Satya Nadella.

The trial is expected to provide a rare public examination of OpenAI’s evolution from a nonprofit founded in 2015 in Brockman’s apartment into one of the world’s most valuable artificial intelligence companies, currently estimated to be worth more than $850 billion.

Musk testified that his concerns about artificial intelligence safety were central to OpenAI’s founding and intensified after discussions with former U.S. President Barack Obama and with Larry Page, whom he said did not take the risks of advanced AI seriously enough.“We had to have a counterpoint against Google,” Musk said.

OpenAI disputed that characterization, with Savitt telling jurors that Musk had dismissed employees focused on AI safety and that such concerns were not his primary motivation.

Musk has said he contributed about $38 million to OpenAI before leaving its board, later objecting to its restructuring and Microsoft’s multibillion-dollar investment.

Microsoft lawyer Russell Cohen said the company had acted properly throughout its partnership with OpenAI and described it as “a responsible partner every step of the way.”

Chinese startups are setting up operations in Singapore to reassure global clients that their intellectual property is insulated from Beijing’s oversight, while U.S. firms are drawn by easier access to international talent amid tightening visa rules at home, industry executives and analysts said.

Kerry Goh, chief executive of Kamet Capital, said relocating operations to Singapore provides “comfort” to international clients by ensuring data and intellectual property are governed locally. He cited support for a new AI video venture launched by former executives of Alibaba as an example of this shift.

The trend reflects broader fallout from intensifying Sino-U.S. competition over advanced technologies, including export controls and talent mobility restrictions. Policies under U.S. President Donald Trump, particularly changes to H-1B visa rules, have made it harder for companies to deploy global workforces in the United States.

Singapore has responded with incentives aimed at building an AI-focused economy, including fast-track visas for skilled workers and tax benefits for intellectual property registration. Officials say these measures have strengthened the country’s appeal as a technology hub.

Major global firms are expanding their presence. AI developer Anthropic is planning a Singapore office, according to people familiar with the matter, joining companies such as OpenAI, Meta’s Superintelligence Labs, and Google’s DeepMind.

At the same time, the shift has raised concerns among policymakers. Washington has tightened restrictions on advanced chip exports, including limits on sales by Nvidia to China, while Beijing has reportedly imposed constraints on talent mobility for some AI firms expanding overseas.

Analysts warn Singapore’s growing role as a “neutral” jurisdiction could draw scrutiny from both sides. Chong Ja Ian, a political scientist at the National University of Singapore, said the city-state risks being viewed as a grey zone for technology transfers, potentially prompting regulatory pushback.

Despite such risks, companies continue to be attracted by Singapore’s streamlined visa processes, with some employment passes approved within days, and its reputation as a stable, business-friendly environment.
