By 2025 it had raised $40 billion at a $300 billion valuation, completed a for-profit restructuring, and generated $12 billion in annualized revenue. Here is the full decade. ## Key Topics - OpenAI - Sam Altman - Elon Musk - ChatGPT - GPT - AI History - Silicon Valley - AGI ## Content Structure This article from LLM Rumors covers: - Technical implementation details - Legal analysis and implications - Industry comparison and competitive analysis - Data acquisition and training methodologies - Financial analysis and cost breakdown - Human oversight and quality control processes - Comprehensive source documentation and references ## Full Content Preview TL;DR: OpenAI was incorporated on December 8, 2015, as a nonprofit backed by a $1 billion pledge from some of Silicon Valley's biggest names; only $130 million of that pledge was actually received by 2019.[1] What followed was a decade of structural contradictions: a capped-profit pivot in 2019, a $13 billion Microsoft partnership, a five-day boardroom coup in 2023 that nearly destroyed the company, the departure of co-founder Ilya Sutskever, and a completed for-profit restructuring in October 2025 that left OpenAI Group PBC valued at $300 billion and the nonprofit foundation controlling equity worth $130 billion.[2] The mission was always to benefit humanity. The execution looked a lot like building a tech empire. --- The dinner was at Sam Altman's house in San Francisco. The guests included Elon Musk, Greg Brockman, Ilya Sutskever, and a handful of researchers who were, at that moment, some of the most sought-after people in artificial intelligence. The pitch Altman and Musk made was simple, almost absurd in hindsight: pool resources, publish everything, and race to build artificial general intelligence in the open so that no single corporation could control it. They wanted to save the world by building the thing most likely to end it, and they wanted to do it as a nonprofit. That dinner, and the conversations that surrounded it through 2015, produced what is arguably the most consequential organization in the history of technology. Not because OpenAI built AGI. But because it built ChatGPT, and ChatGPT changed what the public believed computers could do. Everything else followed from that. What the founding mythology tends to skip is the structural reality. The $1 billion pledge was a pledge. By 2019, only $130 million had actually arrived. The "open" in OpenAI had been quietly dropped by the time GPT-3 launched as a closed API in 2020. And the "nonprofit" was restructured into a capped-profit entity just four years after founding, with Sam Altman as CEO and Microsoft as the anchor investor.[3] The real story of OpenAI is a decade of tension between what the founders said they were building and what they actually built. Both things are interesting. But only one of them became a $300 billion company. OpenAI was founded as a nonprofit in December 2015 with 11 co-founders and a $1 billion pledge. By the time ChatGPT launched in December 2022, the company had burned through hundreds of millions of dollars, lost $540 million in a single year, and pivoted to a capped-profit structure to attract serious capital. By April 2025, it had raised $40 billion in a single round, the largest private technology deal in history, led by SoftBank at a $300 billion valuation.[4] The Founding: A Dinner Party That Built a Lab OpenAI was incorporated on December 8, 2015, with an unusual founding team for a Silicon Valley AI company: it had eleven co-founders, a nonprofit structure, and no product. The eleven founders were Sam Altman, Elon Musk (as co-chairs), Ilya Sutskever, Greg Brockman, Trevor Blackwell, Vicki Cheung, Andrej Karpathy, Durk Kingma, John Schulman, Pamela Vagata, and Wojciech Zaremba.[1] The roster reads like a draft pick of the 2015 AI research world. Sutskever had just helped found Google Brain after co-authoring AlexNet with Geoffrey Hinton. Karpathy was finishing his Stanford PhD on deep learning for vision. Schulman would go on to co-develop the reinforcement learning from human feedback (RLHF) techniques that made ChatGPT possible. Brockman had been CTO of Stripe. This was not a group short on ambition or credential. The financial backing was equally high-profile. Sam Altman, Greg Brockman, Elon Musk, Reid Hoffman, Jessica Livingston, Peter Thiel, Amazon Web Services, and Infosys pledged a combined $1 billion. The operative word is "pledged."
