From North Dakota Through Stripe to OpenAI’s Founding
Brockman grew up in Thompson, North Dakota, won chemistry and math olympiads, started at Harvard in 2008, transferred to MIT after a year, then dropped out in 2010 to join Stripe, the company of his MIT classmate Patrick Collison. In 2013 he became its first CTO. In 2015 he left, met with Sam Altman and Elon Musk, and personally recruited OpenAI’s founding team, including Ilya Sutskever; the company started in his living room. He led the OpenAI Gym and OpenAI Five projects (a Dota 2 bot), and on March 14, 2023, he livestreamed the GPT-4 demo to the world.
November 2023 and the Return
On November 17, 2023, the day Sam Altman was fired, the board removed Brockman from the board of directors; Ilya Sutskever had provided the board with a document about alleged intimidation, and Mira Murati claimed Brockman’s relationship with Altman made it impossible for her to work. Brockman resigned the same day, on November 20 Microsoft announced that both he and Altman would join a new research team, and a day later he returned to OpenAI along with the reinstated Altman. From August to November 2024 he was on leave. In May 2026, a jury dismissed Elon Musk’s lawsuit against OpenAI, Altman, and Brockman, finding the claims time-barred.
Money and Politics
According to Bloomberg in July 2026, his net worth was $25.5 billion, almost entirely in OpenAI equity. In 2025, Brockman and his wife were the largest donors to the MAGA Inc. committee supporting Donald Trump ($12.5 million each) and gave $50 million to the Leading the Future committee, founded with Marc Andreessen to advocate for AI deregulation. This distinguishes him from Dario Amodei and Altman, who in September 2026 called for slowing AI development. A full overview of all figures in the industry is on our Who’s Who in AI page.
