OpenAI

Who owns OpenAI?
OpenAI has a complex ownership structure. The company was founded as a non-profit (OpenAI, Inc.) and created a capped-profit subsidiary in 2019. Major investors include Microsoft (approximately $13 billion invested), Thrive Capital, SoftBank, and other venture capital firms. OpenAI is in the process of converting to a public benefit corporation, which would give the non-profit a significant equity stake but remove its control over operations.

Is OpenAI publicly traded?
No, OpenAI is a private company. The company completed a $6.6 billion funding round at a $157 billion valuation in October 2024. There is no current timeline for an IPO, though the planned conversion to a public benefit corporation could eventually facilitate a public offering.

What is OpenAI's annual revenue?
OpenAI reported annualized revenue of approximately $3.7 billion in late 2024, with rapid growth driven by ChatGPT subscriptions and enterprise API usage. The company projected revenue of approximately $11.6 billion for 2025.

Who founded OpenAI?
OpenAI was founded in December 2015 by Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, Wojciech Zaremba, and John Schulman, among others. Elon Musk resigned from the board in 2018. Sam Altman has served as CEO since the company's founding, with a brief five-day interruption in November 2023 when the board fired and then reinstated him.

What is ChatGPT?
ChatGPT is OpenAI's AI chatbot, launched in November 2022. It reached 100 million users in two months, making it the fastest-growing consumer application in history. ChatGPT has more than 300 million weekly active users as of late 2024 and is available as a free tier and paid subscriptions (Plus at $20/month, Team, and Enterprise).

What is the relationship between OpenAI and Microsoft?
Microsoft has invested approximately $13 billion in OpenAI and is the company's primary cloud and commercial partner. Microsoft integrates OpenAI's models into products including Bing, GitHub Copilot, Microsoft 365 Copilot, and Azure OpenAI Service. Microsoft has exclusive rights to commercialize OpenAI's technology through Azure. The partnership is central to both companies' AI strategies.

OpenAI was founded in December 2015 as a non-profit artificial intelligence research laboratory in San Francisco. The founding group included Sam Altman (then president of Y Combinator), Elon Musk (CEO of Tesla and SpaceX), Greg Brockman, Ilya Sutskever, Wojciech Zaremba, and John Schulman, along with other researchers and investors. The founders committed approximately $1 billion in initial funding.

The founding mission was to ensure that artificial general intelligence (AGI) would benefit all of humanity, with a particular concern about the risks of AGI being developed by a single company without adequate safety research or public accountability. The non-profit structure was intended to ensure that OpenAI's work would be guided by this mission rather than by profit maximization.

In its early years, OpenAI published significant research on reinforcement learning, including the development of OpenAI Gym (a toolkit for reinforcement learning research) and OpenAI Five (an AI system that defeated professional players at the video game Dota 2). The company also developed the GPT-1 language model in 2018, demonstrating the potential of large-scale language modeling.

Elon Musk resigned from OpenAI's board in February 2018, citing potential conflicts of interest with Tesla's AI development for autonomous vehicles. Musk later became a critic of OpenAI's direction and filed a lawsuit against the company in 2024 alleging that it had abandoned its non-profit mission.

In 2019, OpenAI transitioned to a hybrid structure, creating OpenAI LP, a "capped-profit" for-profit entity controlled by the non-profit OpenAI, Inc. The capped-profit structure limited investor returns to 100 times their investment, with any excess going to the non-profit. This structure allowed OpenAI to raise the large amounts of capital needed for AI research while maintaining non-profit oversight.

Microsoft invested $1 billion in OpenAI in 2019, beginning a strategic partnership that would become central to both companies' AI strategies. Microsoft subsequently invested an additional $2 billion in 2021 and approximately $10 billion in January 2023, bringing its total investment to approximately $13 billion. In exchange, Microsoft received exclusive rights to commercialize OpenAI's technology through its Azure cloud platform and integrated OpenAI's models into products including Bing, GitHub Copilot, and Microsoft 365 Copilot.

GPT-3, released in June 2020, was a major breakthrough in large language model capabilities, demonstrating that scaling model size and training data could produce dramatically improved performance on a wide range of language tasks. GPT-3 had 175 billion parameters, far larger than any previous language model.

The launch of ChatGPT in November 2022 was a watershed moment for the AI industry. ChatGPT, a conversational interface built on the GPT-3.5 model, reached 1 million users in five days and 100 million users in two months, making it the fastest-growing consumer application in history. The launch sparked a wave of AI investment and competition, with Google, Meta, Amazon, and many startups accelerating their AI development programs.

GPT-4, released in March 2023, demonstrated further improvements in reasoning, accuracy, and multimodal capabilities (the ability to process both text and images). OpenAI also released DALL-E 3 (image generation), Whisper (speech recognition), and Sora (video generation) as part of its expanding product portfolio.

In November 2023, OpenAI's board of directors abruptly fired Sam Altman as CEO, citing a loss of confidence in his leadership. The firing triggered a crisis at the company, with nearly all of OpenAI's employees threatening to resign if Altman was not reinstated. Microsoft offered to hire Altman and other departing employees. Within five days, Altman was reinstated as CEO and the board members who had fired him resigned. The episode highlighted governance tensions in OpenAI's unusual non-profit/for-profit structure.

In late 2024, OpenAI announced plans to convert from its hybrid structure to a public benefit corporation (PBC), which would remove the non-profit's control over the for-profit entity. The conversion was announced alongside the $6.6 billion funding round at a $157 billion valuation.
