OpenAI on Friday clapped back against Elon Musk, one of its co-founders, after the billionaire’s request last month for a federal court to stop the ChatGPT-maker from converting to a fully for-profit business.

In a blog post titled “Elon Musk wanted an OpenAI for-profit,” the startup alleged that in 2017, Musk “not only wanted, but actually created, a for-profit” to serve as the company’s proposed new structure.

“When he didn’t get majority equity and full control, he walked away and told us we would fail,” OpenAI wrote in the blog post. “Now that OpenAI is the leading AI research lab and Elon runs a competing AI company, he’s asking the court to stop us from effectively pursuing our mission.”

Musk and xAI did not immediately respond to requests for comment.

Since Musk announced the debut of xAI, his OpenAI competitor, in July 2023, the startup has released its Grok chatbot and is raising up to $6 billion at a $50 billion valuation, in part to buy 100,000 Nvidia chips, CNBC reported last month.

Musk was questioning OpenAI’s nonprofit model from day one, a member of OpenAI’s legal team told CNBC.

OpenAI’s “structure doesn’t seem optimal,” Musk wrote in a November 2015 email to OpenAI CEO Sam Altman, according to screenshots shared in the blog post. He added that receiving a “salary from the nonprofit muddies the alignment of incentives,” and that it’s “probably better to have a standard C corp with a parallel nonprofit.”

In a text conversation with former board member Shivon Zilis, OpenAI co-founder Greg Brockman wrote that a conversation he had with Musk “turned into talking about structure” and that Musk “said non-profit was def the right one early on, may not be the right one now,” according to blog screenshots.

Musk forwarded an article about China’s strategy for AI research facilities to Brockman and fellow OpenAI co-founder Ilya Sutskever. Musk wrote that China “will do whatever it takes to obtain what we develop. Maybe another reason to change course,” per the blog post.

Brockman agreed, and he wrote that starting in 2018, OpenAI’s path would need to be a “Al research + hardware for-profit,” according to the blog post. Musk wrote back, “Let’s talk Sat or Sun. I have a tentative game plan that l’d like to run by you.”

Altman, Brockman, Musk and others negotiated terms for the planned OpenAI for-profit in the fall of 2017, but the talks fell apart due to disagreements about equity, control and who would be CEO, according to the blog. Musk initially proposed that he should “unequivocally have initial control of the company” but said “this will change quickly” when the board has 12 to 16 members, per screenshots.

Musk created a public benefit corporation called “Open Artificial Intelligence Technologies, Inc” in September 2017, according to screenshots included in OpenAI’s blog post. A few days later, OpenAI rejected Musk’s proposed terms for the for-profit and offered to keep the conversation going, but Musk responded that his offer was “no longer on the table” and that “discussions are over,” per screenshots.

In January 2018, Musk proposed that OpenAI spin into Tesla, his electric vehicle company, according to the blog.

“The only paths I can think of are a major expansion of OpenAl and a major expansion of Tesla Al. Perhaps both simultaneously. The former would require a major increase in funds donated and highly credible people joining our board. The current board situation is very weak,” Musk wrote, according to the blog. He added that “OpenAI is on a path of certain failure relative to Google.”

Brockman responded with a lengthy plan, including the idea that the company should “try our best to remain a non-profit,” according to screenshots. In February 2018, Musk resigned as co-chair of OpenAI.

OpenAI originally debuted in 2015 as a nonprofit and then in 2019 converted into a “capped-profit” model, in which the OpenAI nonprofit was the governing entity for its for-profit subsidiary. Altman claimed onstage last week at the DealBook Summit that the company decided to go to a capped-profit structure in part because Musk stopped funding them.

Thanks largely to the viral spread of ChatGPT, which debuted in November 2022, OpenAI has become one of the hottest, and at times one of the most controversial, startups on the planet. The company’s valuation has climbed to $157 billion since it launched ChatGPT. OpenAI has raised about $13 billion from Microsoft, and it closed its latest $6.6 billion round in October, led by Thrive Capital and including participation from chipmaker Nvidia, SoftBank and others.

The company also received a $4 billion revolving line of credit, bringing its total liquidity to more than $10 billion. OpenAI expects about $5 billion in losses on $3.7 billion in revenue this year, CNBC confirmed in September with a person familiar with the situation.

OpenAI is now in the midst of a potentially two-year process of converting into a fully for-profit public benefit corporation, which could make it more attractive to investors. The restructuring plan would also allow OpenAI to retain its non-profit status as a separate entity, CNBC previously reported.

OpenAI has faced increasing competition from startups such as Musk’s xAI and Anthropic, as well as tech giants such as Google, Amazon and Meta. The generative AI market is predicted to top $1 trillion in revenue within a decade, and business spending on generative AI surged 500% this year, according to recent data from Menlo Ventures.

Attorneys representing Musk, his AI startup xAI and Zilis filed for a preliminary injunction against OpenAI on Nov. 29.

In their motion for preliminary injunction, attorneys for Musk argued that OpenAI should be prohibited from “benefitting from wrongfully obtained competitively sensitive information or coordination via the Microsoft-OpenAI board interlocks.”

The latest court filings represent an escalation in the legal feud between Musk, OpenAI and Altman, as well as other long-involved parties and backers including tech investor Reid Hoffman and Microsoft.

Musk in March 2024 sued OpenAI — and co-founders Altman and Brockman — in a San Francisco state court, alleging breach of contract and fiduciary duty. In the suit, Musk claimed that the early OpenAI team had set out to develop artificial general intelligence “for the benefit of humanity,” but that the project had been transformed into a for-profit entity that’s largely controlled by principal shareholder Microsoft.

In June, Musk withdrew that complaint and later refiled in federal court. Attorneys for Musk in the federal suit, led by Marc Toberoff in Los Angeles, argued in their complaint that OpenAI had violated federal racketeering, or RICO, laws.

In November, they expanded their complaint to include allegations that Microsoft and OpenAI had violated antitrust laws when the ChatGPT maker allegedly asked investors to agree to not invest in rival companies, including Musk’s xAI.

“Microsoft and OpenAI now seek to cement this dominance by cutting off competitors’ access to investment capital (a group boycott), while continuing to benefit from years’ worth of shared competitively sensitive information during generative AI’s formative years,” the lawyers wrote in the November filing. They added that the terms OpenAI asked investors to agree to amounted to a “group boycott” that “blocks xAI’s access to essential investment capital.”

Altman denied that OpenAI investors can’t invest in competitors during an onstage interview last week at The New York Times’ DealBook Summit. Altman said that investors are welcome to do so but that the company will stop their “information rights,” such as sharing its research road map and other materials.

Microsoft has invested nearly $14 billion in OpenAI but revealed in October that it would record a $1.5 billion loss in the current period largely due to an expected loss from the AI startup. Microsoft gave up its observer seat on OpenAI’s board in July, although CNBC reported that the Federal Trade Commission would continue to monitor the influence of the two companies over the AI industry.
