    OpenAI

    Also known as OpenAI Group PBC, OpenAI Foundation

    OpenAI is a US artificial intelligence company that released ChatGPT in November 2022 and develops the GPT family of models.[1] Since October 2025 its business has been run by OpenAI Group PBC, a public benefit corporation controlled by the nonprofit OpenAI Foundation.[2] In 2026 it raised $122 billion and confidentially filed for an IPO.[3][4]

    Key facts

    OpenAI is an artificial intelligence company best known for ChatGPT, which it released to the public on November 30, 2022.[1] Sam Altman, a co-founder, is its chief executive.[5] Its last reported valuation, set in March 2026, was $852 billion.[3] Its rivals in building large AI models include Anthropic and Google DeepMind.[6][7]

    History

    OpenAI was incorporated as a nonprofit in Delaware in December 2015.[8] In March 2019 it created OpenAI LP, a “capped-profit” company that limited investor returns to 100 times their investment.[9] Microsoft invested $1 billion in OpenAI the same year.[10]

    OpenAI released ChatGPT to the public in November 2022.[1] According to Altman, the chatbot attracted 1 million users within five days.[11] By March 2026, OpenAI counted more than 900 million weekly active users of its consumer applications, according to a media report.[12]

    Corporate structure

    In October 2025 OpenAI completed a recapitalization. Its for-profit business became OpenAI Group PBC, a public benefit corporation, and the nonprofit became the OpenAI Foundation, with an equity stake valued at about $130 billion.[2]

    Microsoft came out of the recapitalization with an investment valued at about $135 billion, roughly 27 percent of OpenAI Group PBC on an as-converted diluted basis.[13] As part of the same agreement, OpenAI contracted to buy an incremental $250 billion of Azure cloud services, and Microsoft gave up its right of first refusal to be OpenAI’s compute provider.[14] The agreement also says that if OpenAI declares it has reached artificial general intelligence (AGI), an independent expert panel must verify the declaration. Microsoft’s rights to OpenAI’s intellectual property run through 2032.[15]

    Funding and IPO plans

    In March 2026 OpenAI raised $122 billion at an $852 billion valuation, according to media reports, which described it as the largest funding round in Silicon Valley’s history.[3] SoftBank led the round with several investment firms, and earlier backers Amazon, Nvidia and Microsoft also took part.[16]

    In June 2026 OpenAI said it had confidentially submitted a draft registration statement to the US Securities and Exchange Commission for a proposed initial public offering (IPO). It added that it had not decided on timing, and that some things it wanted to do were likely easier as a private company.[4] In late September 2026, Bloomberg reported that OpenAI was in talks to raise at least $30 billion at a valuation of roughly $1.4 trillion, as a bridge round before an IPO.[17]

    Products and models

    OpenAI’s main products are ChatGPT, the Codex coding tool and an API for developers.[18] In early September 2026 it launched GPT-6 Astra, which it described as its best model for a range of tasks.[19] On September 22, 2026 it released GPT-6 Sol and GPT-6 Luna, smaller models priced at half the cost of its previous 5.6 series.[18] OpenAI said GPT-6 Sol makes about half as many mistakes as its predecessor.[20]

    OpenAI’s o1 model series is trained with large-scale reinforcement learning to reason through a chain of thought before answering.[21] OpenAI rated GPT-6 Astra at a Critical level of cybersecurity capability, meaning that with tools and access the model can find previously unknown security flaws and develop new ways to exploit them.[22] The frontier AI tracker follows these releases.

    For computing power, OpenAI agreed in October 2025 to deploy 6 gigawatts of AMD Instinct GPUs across several product generations, starting with 1 gigawatt of MI450 GPUs in the second half of 2026.[23]

    Revenue

    In October 2026 the Financial Times reported that OpenAI had told investors its annualized revenue was approaching $50 billion, below a $70 billion figure that had circulated earlier.[24] Comparisons with rivals are complicated because Anthropic counts sales made through its cloud partners in its annualized revenue, while OpenAI does not.[6]

    Questions readers ask

    Is OpenAI a nonprofit?

    It started as one. Since October 2025 its business has been OpenAI Group PBC, a for-profit public benefit corporation, while the nonprofit, renamed the OpenAI Foundation, holds an equity stake valued at about $130 billion.[8][2]

    How much of OpenAI does Microsoft own?

    After the October 2025 recapitalization, Microsoft held roughly 27 percent of OpenAI Group PBC on an as-converted diluted basis, valued at about $135 billion.[13]

    Is OpenAI a public company?

    No. In June 2026 it confidentially submitted a draft IPO registration statement to the SEC but said it had not decided on timing.[4]

    What is OpenAI's latest model?

    As of late September 2026, OpenAI's newest generation was GPT-6, including GPT-6 Astra and the lower-cost GPT-6 Sol and GPT-6 Luna.[19][18]
