OpenAI

The San Francisco lab founded as a nonprofit in December 2015 to build artificial general intelligence "for the benefit of humanity". It became a capped-profit company funded by Microsoft in 2019, launched ChatGPT in November 2022 and so started the generative-AI boom, and in October 2025 became a public benefit corporation controlled by a renamed nonprofit foundation. It has the largest consumer AI product in the world (ChatGPT, ~900m weekly users and >50m paying subscribers by early 2026, company claims) and the largest compute commitments of any lab (~$1.4tn over ~8 years, Altman, November 2025). Revenue rose from ~$3.7bn (2024) to ~$13.1bn (2025, company figure cited at the March 2026 round), and the annualised run-rate was reported near ~$70bn by late September 2026 (Axios, reported). It raised $122bn at an $852bn post-money valuation (31 March 2026), filed confidentially for an IPO (June 2026) and was in early talks in autumn 2026 to raise at ~$1.4tn (reported). Its history is also a list of governance shocks: the five-day removal of Sam Altman (November 2023), the 2024 departures of its safety leaders, Elon Musk's lawsuit (2024–26), and the long fight over its conversion to a for-profit company.
