Sam Altman and Elon Musk: What’s Their Relationship Like?
Silicon Valley thrives on unlikely partnerships that change the world. The Sam Altman and Elon Musk saga started with shared dreams of responsible AI development. Their initial collaboration at OpenAI promised to democratize artificial intelligence for everyone. Then money, control, and competing visions tore them apart. You’re about to discover how two allies became archenemies and what it means for your entrepreneurial journey.
OpenAI’s founding as a non-profit research lab in 2015 was driven by concerns about the existential risks of the technology. Both visionaries worried that unchecked AI development could threaten humanity’s future. Musk contributed crucial early funding while Altman provided operational leadership. Their partnership seemed destined to reshape technology forever.
Breaking Ranks: The Musk Departure (2018)
In 2018, Musk resigned from OpenAI’s Board of Directors position. He cited “a potential conflict of interest” with his role as Tesla CEO. After all, Tesla was developing its AI for self-driving cars. However, the official reason masked deeper tensions brewing beneath the surface.
Behind the scenes, Musk had clashed with the rest of the team over money and control. He had promised additional funding but ultimately backed out of a commitment to pour more cash into the lab.
The reasons for the split were partly philosophical. By late 2017, Altman and others concluded that achieving powerful AI would require vast capital and computing. That was far beyond what a nonprofit could easily muster. As such, they began creating a capped-profit subsidiary, OpenAI LP, to raise billions.
Musk’s reaction was mixed. Internally, he sought control. In emails summarized by OpenAI, he wanted the majority equity, initial board control, and the CEO slot of any for-profit spinoff. At one point, Musk even proposed that OpenAI merge with Tesla as its cash cow to take on Google.
However, Altman and the other cofounders hesitated. As Altman later told Lex Fridman, Elon thought OpenAI was going to fail. But that’s not all. He was also aiming for total control of the company. What’s more, he also wanted to turn it into a for-profit company or integrate it into Tesla. However, Altman and the team didn’t want to do that. Seeing that his demands were not met, Musk decided to leave.
Musk downplayed the public negativity after his resignation. “I didn’t agree with some of what the OpenAI team wanted to do,” he wrote, “so it was just better to part ways on good terms.” Altman continued as OpenAI’s CEO, while Musk turned his attention back to Tesla, SpaceX, and other ventures.
Rival Visions (2019-2022)
After Musk’s departure, OpenAI underwent major changes. In 2019, OpenAI created a for-profit subsidiary that fundamentally altered its structure. This transformation would become the core of their future legal battles.
Altman steered OpenAI toward commercial success while maintaining nonprofit oversight. Microsoft emerged as a key partner, providing billions in funding and computing resources. The partnership accelerated OpenAI’s development timeline dramatically.
Meanwhile, Musk focused on Tesla’s autonomous driving technology and acquired Twitter in 2022. His AI interests remained secondary until competition heated up. The stage was set for a confrontation between former partners.
Musk’s Jab
After acquiring Twitter, Musk then founded his own AI company, xAI, in 2023. Launching xAI represented Musk’s direct challenge to OpenAI’s dominance. He positioned his company as the “true” open-source alternative to ChatGPT.
Musk began criticizing OpenAI’s commercial pivot publicly through Twitter posts. He accused Altman of abandoning their original nonprofit mission for profit. In one post, he said, “I’m still confused as to how a non-profit to which I donated $100M somehow became a $30B market cap for-profit. If this is legal, why doesn’t everyone do it? His attacks grew more personal as competition intensified between xAI’s Grok and OpenAI’s ChatGPT.
Altman Response
Altman responded on X: “This is a remarkable claim given what I’ve heard Elon does to manipulate X to benefit himself and his own companies and harm his competitors and people he doesn’t like.”He even mentioned Musk’s earlier push for a for-profit structure as evidence. In fact, OpenAI later released Musk’s emails showing he supported a for-profit arm. However, by now the relationship was very strained.
Altman defended OpenAI’s evolution as necessary for advancing AI safety research. He argued that massive capital requirements made some commercial structure inevitable. The nonprofit board retained ultimate control over key decisions.
Sam Altman and Elon Musk: Feud, Lawsuits, and Public Spats (2023-2024)
Musk Lawsuits
On Feb. 29, 2024, Musk filed a lawsuit in California against OpenAI and Altman, accusing them of abandoning the startup’s original mission. The suit argued that Altman and co-founder Greg Brockman had promised an open-source, non-profit venture, but instead, OpenAI was now focused on profit. He went on to ask the court to force OpenAI to release its technology publicly and to prevent its products like GPT-4 from being used for profit by Microsoft and others.
OpenAI response
OpenAI hit back immediately. In court filings, they derided Musk’s complaint as incoherent and a thinly veiled attempt to boost his own AI interests. According to the company’s lawyers, Musk wanted OpenAI’s success after seeing its success with technology.
In a pointed answer, Altman soon noted in interviews that Musk had long sought control of the company. “He thought OpenAI was going to fail. We didn’t want to do that, and he decided to leave,” he told Lex Fridman. In March 2024, OpenAI even published internal emails showing Musk had supported plans for a for-profit subsidiary and a Tesla merger.
Withdrawal and Filing New Lawsuits
Musk abruptly withdrew the lawsuit in June 2024, with no public explanation. However, in August, he filed a new lawsuit targeting OpenAI’s $13 billion partnership with Microsoft. He challenged a judge’s ruling that Microsoft’s license was void and that OpenAI had broken its nonprofit charter by taking the money.
The complaint accused Altman of flipping the narrative and cashing in on Microsoft’s partnership. Musk argued that OpenAI and Microsoft were set to profit from technology that was originally meant to be free and open. In short, he framed it as a fight to preserve OpenAI’s original idealism.
OpenAI shrugged and pointed to its nonprofit parent and to the board’s oversight. To this end, Musk’s claims didn’t hold legal ground.
The Sam Altman and Elon Musk Virtual War
Throughout this period, both men used public forums to sharpen jabs. Musk regularly criticized OpenAI on X, calling Altman’s move to a for-profit model illegal. Meanwhile, in early 2025, Altman told Bloomberg News that Musk’s $97.4 billion bid for OpenAI’s nonprofit arm was a tactic to stall competition. “He’s obviously a competitor. I think he’s probably just trying to slow us down,” Altman said.
Altman did not mince words about Musk’s motivations. When asked about the bid, he quipped, “Probably his whole life is from a position of insecurity… I don’t think he’s a happy person. I do feel for him.”. Those comments made headlines worldwide, underscoring how personal the rivalry had become.
2025 Billion-Dollar Bids and Social Media Sparks
In February 2025, Musk took the feud to yet another level with an astonishing bid. According to media reports, he quietly assembled a consortium to offer $97.4 billion for OpenAI’s nonprofit parent company. He framed the move as a mission-driven rescue. In a statement, he claimed the goal was returning OpenAI to an ‘open-source, safety-focused force for good.
Sam Altman was unimpressed. At an AI summit in Paris, he flatly announced OpenAI was not for sale. On CNBC, he quipped that they’d consider buying Twitter instead. Altman accused Musk of crazy tactics, citing lawsuits and public stunts, rather than competing by building a better AI product.
To this end, Musk’s latest gambit became fodder for back-and-forth. Altman jokingly tweeted, “No thank you, but we will buy Twitter for $9.74 billion if you want,” Musk fired back on X with a one-word insult, “Swindler.”
By mid-2025, this skirmish showed signs of calming. Altman told CNBC’s Squawk Box that in reality, he doesn’t spend much time thinking about Musk. Indeed, after ChatGPT-5’s launch later, Altman said on CNBC simply, “You know, I don’t think about Musk that much”.
At the same time, Axios reported that Musk’s bid had fizzled. He ultimately withdrew it after the feud had played out in the press. An Axios summary noted that Musk has a history of directing X algorithm changes to boost his posts and favor his interests. This reflects how even their corporate leverage became a point of contention.
Personal Reflections Amidst the Rift
Behind the headlines, Sam Altman and Elon Musk still express a complicated mix of respect and rivalry. Altman has publicly said he respects Elon and hopes they can be amicable friends again in the future. In a Lex Fridman podcast conversation, he mused that both he and Musk should compete and win, or build cool shit together.
However, Altman also acknowledges the toxicity of the current feud. He famously commented that Musk seems to operate from a position of insecurity. Musk, for his part, rarely comments directly on Altman personally. Instead, his social-media tirades target OpenAI and its policies rather than Altman’s character.
Nonetheless, both men publicly circle each other like wary sparring partners. After Musk’s revived 2024 lawsuit, Altman emphasized OpenAI’s mission-driven approach. He told a podcast that the core of “open” means giving people free access to powerful AI as a public good.
Meanwhile, Musk insists on Twitter (X) that AI must be open and safe. He often shares memes and messages aimed at an imaginary villain. In one of their most cutting exchanges, he joked that OpenAI should rename itself “CloseAI.” Altman replied dryly that the remark showed just how seriously Musk took the lawsuit. It’s a personal spat played out in public, and each gains fans and critics as they hurl quips and legal threats through the media.
Final Remarks
So far, the Sam Altman and Elon Musk relationship remains linked by history, but is worlds apart in ambition. Even Altman acknowledges Musk foresaw some problems, yet they disagree sharply on strategy and ethics. Altman’s OpenAI has embraced big funding, partnerships, and product deployment. Musk, in contrast, accuses it of selling out the original nonprofit ethos.
Musk’s xAI, however, is free to burn cash and compete openly, while he labels Altman the steward of a Microsoft-backed empire. In public statements, they have alternated between personal jabs and professional critiques. Altman calls Musk insecure; Musk calls Altman a “swindler,” with tweets flying back and forth. However, both leaders also pay lip service to mutual respect.
