OpenAI
TL;DR OpenAI is the world's most valuable private AI company, revolutionizing artificial intelligence research and deployment with products like ChatGPT, GPT-4/5, DALL-E, and Sora, while shaping industry standards and facing massive growth and financial challenges.
2025-10-28 The nonprofit arm, now renamed the OpenAI Foundation, has completed a recapitalisation that consolidates governance of its for-profit arm (OpenAI Group PBC) and places the mission of benefiting all humanity at the centre of both entities. The Foundation now owns equity in the for-profit (currently valued at approximately $130 billion) and will dedicate an initial commitment of $25 billion across two major areas: accelerating health-breakthroughs (such as open datasets and funding scientists) and bolstering technical solutions for AI resilience (to manage both benefits and risks). The restructure follows a year of discussions with California and Delaware regulators and is positioned as a new path forward in delivering safe, aligned intelligence for everyone.
OpenAI, founded in 2015 by prominent tech leaders including Sam Altman and Elon Musk, began as a non-profit dedicated to ensuring artificial general intelligence benefits humanity. Over the next decade, the company shifted to a capped-profit model to attract commercial investment and talent, quickly evolving into the unparalleled leader of the generative AI revolution. OpenAI spearheads breakthroughs in language, image, and video models, becoming synonymous with advanced, democratized AI worldwide.
Headquartered in San Francisco, OpenAI operates under CEO Sam Altman with backing from investors such as Microsoft, SoftBank, and Nvidia. The company is best known for its ChatGPT assistant, which has reached half a billion weekly users and set adoption records for consumer technology worldwide. In 2025, OpenAI is valued at over $500 billion after record-setting fundraising rounds—most notably, a $40 billion raise in March 2025, the largest private tech funding round in history. OpenAI’s product portfolio includes GPT-3, GPT-4, and GPT-5 for natural language understanding, DALL-E for image generation, Whisper for speech recognition, and Sora for video creation. Key partnerships, like its alliance with Microsoft, underpin OpenAI’s cloud scale and integration in mainstream products. The firm projects continued growth while confronting high operating costs and structural changes, including a mandated transition to a Delaware Public Benefit Corporation by 2025’s end.
