Elon Musk

In a United States court, OpenAI chief executive Sam Altman has rejected claims from fellow tech mogul Elon Musk that he betrayed the artificial intelligence company’s original vision.

Tuesday marked the start of Altman’s testimony in a contentious trial unfolding in Oakland, California, between some of tech’s richest and most powerful titans.

Musk, the wealthiest man in the world, has sued Altman and OpenAI president Greg Brockman on the basis that they “stole a charity” by shifting its purpose.

He alleged that OpenAI’s leader persuaded him to invest $38bn, based on a goal of improving humanity, only to see the company pivot to a for-profit venture in 2019.

On the witness stand on Tuesday, Altman instead framed Musk as a competitor obsessed with exercising control over OpenAI.

“It does not fit with my conception of the words ‘stealing a charity’ to look at what has actually happened here,” Altman told the court.

The two men have long had an acrimonious relationship, driven in part by differing views about artificial intelligence.

Musk — a self-described free speech “absolutist” — currently runs his own AI chatbot, Grok, which has been accused of perpetuating right-wing conspiracy theories and offensive materials.

He is seeking $150bn in damages from OpenAI and Microsoft, one of its principal investors.

Altman’s testimony comes more than two weeks into the trial, which has seen him and Musk square off against each other.

In his testimony, Altman argued that Musk knew of the plans to develop OpenAI into a for-profit enterprise when he invested, and he asserted that Musk even petitioned to have a majority stake in the company.

“An early number that Mr Musk threw out was that he should have 90 percent of the equity to start,” Altman told the jury. “It then softened, but it always was a majority.”

The outcome of the trial could determine the future of OpenAI, its leadership, and products like ChatGPT. As part of his lawsuit, Musk is pushing for the removal of Altman and Brockman.

The trial comes as OpenAI prepares for a potential initial public offering that could see it valued at $1 trillion, a historically large sum.

During earlier testimony, Musk portrayed Altman as a liar who could not be trusted with the development of the technology.

“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 said.

Musk’s lawyer, Steven Molo, also sought to undermine Altman’s reliability during questioning on Tuesday.

“Have you misled people when you do business?” Molo asked Altman.

“I do not think so,” Altman replied.

Altman, meanwhile, sought to cast doubt on Musk’s leadership; Musk ultimately left OpenAI’s board in 2018 to pursue his own AI development.

“I don’t think Mr Musk understood how to run a good research lab,” Altman said. “He had demotivated some of our most key researchers.”

The US public, for its part, has been largely unconvinced by high-minded rhetoric about the transformative potential of AI.

A March 2026 poll by the Pew Research Center suggested that a majority of respondents in the US believe AI will worsen, rather than improve, the ability to think creatively, form meaningful relationships, make difficult decisions, and solve problems.

Just 10 percent of respondents said they were more excited than concerned about the increased use of AI in daily life.

But the industry has been quick to translate its substantial economic power into political influence as lawmakers consider how best to regulate the technology.

The use of AI has emerged as an election-season issue as the US midterms approach in November, and the administration of President Donald Trump has proposed a “national policy framework” for the technology to avoid a patchwork of state regulations.

The AI industry has become a driver of eye-watering investment in recent years, with the United Nations estimating that the global market could be worth $4.8 trillion by 2033.

WASHINGTON — The chair of the House Oversight Committee has sent a letter to OpenAI Chief Executive Sam Altman requesting information about potential conflicts of interest between Altman’s personal investments and his operation of the company.

The letter, sent Friday, comes amid a high-stakes legal battle currently playing out in an Oakland federal courtroom between one-time partners Altman and Elon Musk, the world’s richest man, who in 2015 co-founded the AI company best known for creating ChatGPT.

The company was first established solely as a non-profit corporation and the letter sent to Altman by Rep. James Comer (R-Ky.), the Republican chair of the Oversight committee, indicates that the committee is “investigating potential conflicts of interest involving capital from nonprofit corporations invested in startups and other for-profit companies.”

Comer has requested by May 22 a briefing from the company official responsible for oversight of potential conflicts involving company officers and directors, including Altman, as well as all documents related to conflict of interest policies and guidance for those executives.

While OpenAI was created as a non-profit designed to responsibly harness the power of the emerging artificial intelligence technology, the company created a for-profit subsidiary in 2019 and three years later released ChatGPT, which jumpstarted widespread adoption of the technology.

Musk, the chief executive of Tesla, left Open AI’s board in 2018, one year before the creation of the for-profit arm. He is arguing that Altman and another co-founder, Greg Brockman, betrayed the original mission of the non-profit organization, driven by their desire to “cash in” on the technology.

Musk added Microsoft, a significant investor in OpenAI, to the lawsuit in 2024. OpenAI is rumored to be gearing up to go public later this year or early next, and was recently valued at $852 billion.

Musk has said that he invested $38 million in the OpenAI non-profit, but he does not stand to benefit from a potential OpenAI public offering.

He created a rival company xAI in 2023 that was later folded into his company SpaceX

In the lawsuit, Musk is seeking $150 billion in damages, for Altman to be removed from the company and for the company to be fully returned to its non-profit status.

Musk’s complaint also alleges that Altman engaged in self-dealing by directing OpenAI to pursue deals with companies in which he also held a personal stake, including nuclear fusion power company Helion.

Comer’s letter cites reporting that Altman’s pursuit of a Helion deal, which is still ongoing, would come at a lofty valuation of the power-company, boosting the company’s worth, and the value of Altman’s investment.

Altman was briefly forced to step down from leadership of OpenAI in 2023 in part due to concerns about potential conflicts between his personal investments and his operation of the company, but was soon reinstated.

While the company’s board created an audit committee to investigate the potential conflicts of Altman and other officers, the findings were never disclosed.

Comer has requested that Altman turn over all documents and communication related to that audit committee.

Representatives for OpenAI did not immediately respond to requests for comment.

May 11 (UPI) — President Donald Trump will be accompanied by 16 senior executives of U.S. companies for his trip to Beijing to meet with Chinese President Xi Jinping.

The White House on Monday shared a list of the executives, which include Tesla’s Elon Musk, Apple’s Tim Cook, BlackRock’s Larry Fink and Boeing’s Kelly Ortberg, among others.

Cisco CEO Chuck Robbins was unable to join the trip, however executives from Blackstone, Cargill, Citigroup, Coherent, GE Aerospace, Goldman Sachs, Illumina, Matstercard, Meta, Micron Technology, Qualcomm and Visa will also travel to China with Trump.

Trump is expected to discuss trade, artificial intelligence, Taiwan and the Iran War, with the creation of a board of investment and a board of trade with China high on his list of goals for his meetings with Xi.

“We’re doing a lot of business [with China], but it’s smart business,” Trump told reporters during a press briefing in the Oval Office on Monday.

“We used to be taken advantage of for years with our previous presidents,” he said. “And now we’re doing great with China. We make a lot of Monday with China.”

The U.S. caravan will depart for Beijing on Tuesday, with meetings scheduled for the rest of the week between the two delegations.

Each of the executives traveling for the meetings has significant business interests in China, which is why they were asked to join Trump for the trip, White House officials have said.

May 8 (UPI) — The Department of Government Efficiency illegally canceled roughly $100 million in grants that Congress had approved the National Endowment for the Humanities to award, a judge ruled.

U.S. District Court Judge Colleen McMahon said Thursday in a 143-page decision that DOGE and the Trump administration had “no constitutional authority to block, amend, subvert or delay spending appropriations based on the president’s own policy preferences,” CBS News and The Washington Post reported.

DOGE used ChatGPT to revoke grants the NEH had already awarded that it thought were related to diversity, equity and inclusion programs the administration sought to rapidly eliminate throughout the federal government in 2025.

The NEH was one of 16 “small agencies” that President Donald Trump last May marked for elimination in his 2026 budget proposal, which the DOGE effort, as spearheaded by Elon Musk, had already started culling expenditures from.

“The termination of NEH grants challenged in this action was unlawful because it was undertaken in violation of the First Amendment, in violation of the equal protection component of the Fifth Amendment and without statutory authority,” McMahon wrote in the decision.

The lawsuit was brought by the American Council of Learned Societies, the American Historical Association and the Modern Language Association of America after DOGE cut more than 1,400 grants that had been awarded to scholars, research institutions and humanities organizations.

McMahon said that because Congress had not given DOGE the authority to “identify, select or direct the termination of the grants,” she permanently enjoined the government from terminating all of the grants referenced in the lawsuit, as well as from cutting any others using the arguments rejected in the ruling.

Representatives of the three organizations hailed the ruling and said they would continue to push for the full restoration of all the NEH grants, which includes “staff, programs and capacity to serve the public it was created to support.”

“This ruling is an important achievement in our effort to restore the NEH’s ability to fulfill the vital mission with which Congress charged it,” Sarah Weicksel, executive director of the American Historical Association, said in a press release.

“From history exhibitions and path breaking scholarship to library programs and professional development opportunities, the humanities help us understand our past and ourselves, providing all of us with the essential tools for our future,” she said.

May 4 (UPI) — Elon Musk on Monday settled a lawsuit filed against him by the Securities and Exchange Commission for $1.5 million after the agency accused him of breaking securities laws.

The SEC alleged in January 2025 that Musk cost Twitter shareholders $150 million because he delayed disclosing his purchase of more than 5% of shares in the company within the 10 days required by law.

Musk’s purchase of Twitter led to a series of lawsuits because of how he purchased the company, which has since been renamed to X, which saw him become its biggest shareholder before he launched a successful hostile takeover, The Washington Post reported.

In the settlement, which still needs to be approved by a judge, would see Musk pay a $1.5 million penalty while allowing him to admit no wrongdoing, CNBC reported.

“A trust vehicle has agreed to a small fine for being late on one filing,” Musk attorney Alex Spiro said of the agreement, which will see one of his client’s revocable trusts paying the fine.

Musk made a play to buy Twitter in 2022, first buy purchasing more than 5% of the company, which he did not disclose and was the reason the SEC filed suit, which allowed him to put other investors in a poor position before he launched his takeover.

The trial’s outcome could sway the balance of power in AI, and jury selection starts on Monday.

Technology tycoons Elon Musk and Sam Altman are poised to face off in a high-stakes trial revolving around the alleged betrayal, deceit and unbridled ambition that blurred the bickering billionaires’ once-shared vision for the development of artificial intelligence.

The trial, which is scheduled to begin on Monday with jury selection, centres on the 2015 birth of ChatGPT maker OpenAI as a nonprofit start-up primarily funded by Musk before evolving into a capitalistic venture now valued at $852bn.

The trial’s outcome could sway the balance of power in AI, breakthrough technology that is increasingly being feared as a potential job killer and an existential threat to humanity’s survival.

Those perceived risks are among the reasons that Musk, the world’s richest person, has cited for filing a lawsuit in August 2024 that will now be decided by a jury and US District Judge Yvonne Gonzalez Rogers in Oakland, California.

The civil lawsuit accuses Altman, OpenAI’s CEO, and his top lieutenant and a cofounder, Greg Brockman, of double-crossing Musk by straying from the San Francisco company’s founding mission to be an altruistic steward of a revolutionary technology. The lawsuit alleges they shifted OpenAI into moneymaking mode behind his back.

The bitter legal fight may come down to a few pages in one executive’s personal diary.

“This is the only chance we have to get out from Elon,” wrote Brockman in the autumn of 2017. “Is he the ‘glorious leader’ that I would pick?”

Brockman’s diary entry is part of the thousands of pages of internal documents revealed in court.

Musk said the defendants kept him in the dark about their plans, exploited his name and financial support to create a “wealth machine” for themselves, and owe damages for having conned him and the public.

He also wants OpenAI to revert to a nonprofit, for Altman and Brockman to be removed as officers and for Altman to be removed from its board.

OpenAI has brushed off Musk’s allegations as an unfounded case of sour grapes that’s aimed at undercutting its rapid growth and bolstering Musk’s own xAI, which he launched in 2023 as a competitor.

The trial also carries risks for Musk, who last month was held liable by another jury for defrauding investors during his $44bn takeover of Twitter in 2022. Any damaging details about Musk and his business tactics could be particularly hurtful now because his rocket ship maker, SpaceX, plans to go public this summer in an initial public offering that could make him the world’s first trillionaire.
