Last updated: October 23, 2026
Sam Altman is the CEO of OpenAI — the company behind ChatGPT — and one of the most powerful people in artificial intelligence. A former Y Combinator president and Loopt founder, he helped turn a research lab into a defining consumer and enterprise AI company, was briefly fired and reinstated in November 2023, and says his goal is artificial general intelligence. Unusually for a Silicon Valley founder-CEO, he holds no equity in OpenAI; his wealth comes from outside investments.

Who is Sam Altman?
Samuel Harris Altman dropped out of Stanford after two years to co-found Loopt, a location-based social app sold in 2012 for about $43 million. He joined Y Combinator, became its president (2014–2019), and helped shape a generation of startups. In 2015 he co-founded OpenAI as a nonprofit research lab; he became CEO in 2019 as the organization adopted a capped-profit structure and partnered deeply with Microsoft.
ChatGPT’s November 2022 debut made generative AI a mass consumer product overnight. In November 2023 OpenAI’s board fired Altman, only to reinstate him days later after employee and investor revolt — a crisis that became a defining leadership story of the AI boom. He has since pushed model releases, enterprise adoption, and public advocacy for AI regulation while competing with Anthropic, Google, xAI, and others.
