OpenAI says in memo that Musk’s claims ‘stem from Elon’s regrets’ that he’s not part of company

OpenAI executives disputed claims Elon Musk laid out in a lawsuit on Thursday, and said the Tesla CEO is upset that he’s no longer part of the artificial intelligence startup.
“We believe the claims in this suit may stem from Elon’s regrets about not being involved with the company today,” wrote OpenAI Chief Strategy Officer Jason Kwon in an internal memo on Friday that was viewed by CNBC. “It is deeply disappointing to see Elon take this action against a company he helped start, especially given his close collaboration with some of you who are still here working towards the mission.”
Musk co-founded OpenAI in 2015 and stepped down from its board in 2018, four years after saying that AI is “potentially more dangerous than nukes.”
Musk is now suing Microsoft–backed OpenAI and CEO Sam Altman, among others, alleging they abandoned the company’s founding mission to develop artificial intelligence “for the benefit of humanity broadly.”
Since releasing the ChatGPT chatbot to the public in late 2022, OpenAI has become one of the hottest startups on the planet, with a valuation reportedly over $80 billion. The company’s convoluted “capped-profit” structure resulted in Altman being briefly ousted by the board late last year, before an uproar among investors and employees led to his quick reinstatement.
Musk has long wanted recognition for his central role in the creation of OpenAI, and he spent large chunks of the lawsuit telling his version of events. His lawyers said in the suit that Musk was approached in 2015 by Altman and OpenAI co-founder Greg Brockman and agreed to form a nonprofit lab that would develop artificial general intelligence, or AGI, outside of the corporate sphere.
Musk’s attorneys said their client contributed over $15 million to OpenAI in 2016, which was “more than any other donor” and helped the startup build a team of “top talent.” The next year, Musk gave nearly $20 million to OpenAI, which the attorneys reiterated was more than other backers. In total, Musk invested over $44 million into OpenAI from 2016 through September 2020, according to the suit.
Additionally, Musk leased OpenAI’s initial office space “and paid the monthly rental expenses,” the suit said. He was also “present for important company milestones.”
Kwon didn’t dispute Musk’s central role in the early days of OpenAI, but he added some other details. For example, Kwon wrote that Musk at one point indicated he needed “full initial control and majority equity” and later suggested that OpenAI merge with Tesla.
“We did not think either approach was right for the mission,” Kwon wrote.
In the memo, Altman called Musk a hero of his and said the he misses the old version of his co-founder. But he said the company’s mission continues.
While it’s the first time the dispute between the two sides has resulted in a fiery lawsuit, they’ve been at odds for a while.
Before he split with OpenAI, Tesla hired co-founder Andrej Karpathy as senior director of AI. Karpathy returned to OpenAI in 2023. And Musk has been notably vocal in his opposition to OpenAI and its Microsoft partnership in recent years, stating publicly in November that OpenAI had deviated from its original mission.
“OpenAI should be renamed ‘super closed source for maximum profit AI,’ because this is what it actually is,” Musk said onstage at The New York Times’ DealBook conference. Regarding OpenAI’s transformation from an “open source foundation” to a multibillion-dollar for-profit company, Musk said, “I don’t know, is this legal?”
Kwon insisted on Friday that OpenAI is independent and continues to work “to ensure AGI benefits all of humanity.”
Musk’s lawyers didn’t immediately respond to a request for comment.

CoreWeave shares fell about 6% in extended trading on Tuesday even as the provider of artificial intelligence infrastructure beat estimates for second-quarter revenue
Here’s how the company did in comparison with LSEG consensus:
- Earnings per share: Loss of 21 cents
- Revenue: $1.21 billion vs. $1.08 billion expected
Revenue more than tripled from $395.4 million a year earlier, CoreWeave said in a statement. The company registered a $290.5 million net loss, compared with a $323 million loss in second quarter of 2024. CoreWeave’s earnings per share figure wasn’t immediately comparable with estimates from LSEG.
CoreWeave’s operating margin shrank to 2% from 20% a year ago due primarily to $145 million in stock-based compensation costs. This is CoreWeave’s second quarter of full financial results as a public company following its IPO in March.
CoreWeave pointed to an expansion in business with OpenAI, a major client and investor. Also during the quarter, CoreWeave acquired Weights and Biases, a startup with software for monitoring AI models, for $1.4 billion.
In May, management touted 420% revenue growth, alongside widening losses and nearly $9 billion in debt. The stock still doubled anyway over the course of the next month.
CoreWeave shares became available on Nasdaq at the end of the first quarter, after the company sold 37.5 shares at $40 each, yielding $1.5 billion in proceeds. As of Tuesday’s close, the stock was trading at $148.75 for a market cap of over $72 billion.
A CoreWeave data center project with up to 250 megawatts of capacity is set to be delivered in 2026, the company said in the statement.
Executives will discuss the results and issue guidance on a conference call starting at 5 p.m. ET.

The Trump administration is still working out the details of its 15% export tax on Nvidia and AMD and could bring deals of this kind to more companies, the White House’s Karoline Leavitt said Tuesday.
“Right now it stands with these two companies. Perhaps it could expand in the future to other companies,” said Leavitt, the White House’s spokesperson.
“The legality of it, the mechanics of it, is still being ironed out by the Department of Commerce, and I would defer you to them for any further details on how it will actually be implemented,” she continued.
President Donald Trump confirmed on Monday that he had negotiated a deal with Nvidia in which the U.S. government approves export licenses for the China-specific H20 AI chip in exchange for a 15% cut of revenue. Advanced Micro Devices also got licenses approved in exchange for a proportion of its China sales, the White House confirmed.
“I said, ‘If I’m going to do that, I want you to pay us as a country something, because I’m giving you a release,'” Trump said Monday.
“We follow rules the U.S. government sets for our participation in worldwide markets,” Nvidia said in a statement this week.
Trump said the export licenses for AMD and Nvidia were a done deal. But lawyers and experts who follow trade have warned that Trump’s deal may be complicated because of existing laws that regulate how the government can charge fees for export licenses.
The Commerce Department didn’t immediately return a request for comment.
The H20 is Nvidia’s Chinese-specific chip that is slowed down on purpose to comply with U.S. export relations. It’s related to the H100 and H200 chips that are used in the U.S., and was introduced after the Biden administration implemented export controls on artificial intelligence chips in 2023.
Earlier this year, Nvidia said that it was on track to sell more than $8 billion worth of H20 chips in a single quarter before the Trump administration in April said that it would require a license to export the chip.
Trump signaled in July that he was likely to approve export licenses for the chip after Nvidia CEO Jensen Huang visited the White House.
The U.S. regulates AI chips like those made by Nvidia for national security reasons, saying that they could be used by the Chinese government to leapfrog U.S. capabilities in AI, or they could be used by the Chinese military or linked groups.
The Chinese government has been encouraging local companies in recent weeks to avoid using Nvidia’s H20 chips for any government or national security-related work, Bloomberg reported on Tuesday.
