Greg Brockman

Greg Brockman is a cofounder and the president of OpenAI, the San Francisco artificial-intelligence company. When OpenAI was announced as a nonprofit laboratory on December 11, 2015, he was among the backers of its one-billion-dollar funding pledge, with Elon Musk, Sam Altman, Reid Hoffman, Jessica Livingston, Peter Thiel, Amazon Web Services and Infosys, and he became its chief technology officer, with Musk and Altman as co-chairs and Ilya Sutskever as chief scientist.¹²

The 2023 Board Crisis

On November 17, 2023, OpenAI announced that Altman would leave as chief executive and the board, and that Brockman would step down as chairman of the board while remaining at the company. The directors who acted were Sutskever, Adam D'Angelo, Tasha McCauley and Helen Toner.³ Brockman quit instead.⁴ Microsoft's chief executive, Satya Nadella, announced on November 20 that Altman and Brockman would lead a new advanced-research lab inside Microsoft.⁴

OpenAI's announcement of November 29, 2023 was subtitled "Mira Murati as CTO, Greg Brockman returns as President," restoring Mira Murati as chief technology officer, and named a new initial board of Bret Taylor as chair, Larry Summers and D'Angelo. Altman wrote to staff: "Greg and I are partners in running this company. We have never quite figured out how to communicate that on the org chart, but we will." Taylor wrote that the board was "thrilled that Sam, Mira and Greg are back together leading the company."⁵ The review that the board's special committee commissioned from the law firm WilmerHale covered "the November 17, 2023 removal of Sam Altman and Greg Brockman from the OpenAI Board of Directors and Mr. Altman's termination as CEO." On March 8, 2024, the committee recommended that the full board "endorse the November 21 decision to rehire Mr. Altman and Mr. Brockman," and Taylor stated: "We have unanimously concluded that Sam and Greg are the right leaders for OpenAI."⁶

In December 2023 OpenAI's superalignment team published "Weak-to-strong generalization," listing Collin Burns first among its authors and Brockman and Sutskever among its contributors.⁷ Burns was selected in April 2026 to direct the federal Center for AI Standards and Innovation and removed within days.⁸ In February 2024 Musk sued OpenAI, Altman and Brockman in California state court for breach of contract over the company's founding agreement.⁹

Political Giving

On September 12, 2025, Brockman gave 12,500,000 dollars to the super PAC Leading the Future and 12,500,000 dollars to the hybrid political committee MAGA Inc., listing his employer as OpenAI and his occupation as "President and Co-Founder." Anna Brockman of San Francisco gave the same amounts to both committees on the same day; the MAGA Inc. filing lists her occupation as "Retired." The four contributions total 50 million dollars.¹⁰ With 50 million dollars from the management company of Andreessen Horowitz, attributed half to Marc Andreessen and half to Ben Horowitz, and 100,000 dollars from the company behind Perplexity, the Brockmans' 25 million dollars made up Leading the Future's 75.1 million dollars in contributions through July 2026.¹⁰¹¹ The committee passed most of its money to affiliated committees; one of them, Think Big, spent 8,145,697.68 dollars opposing Alex Bores, the New York Assembly member who sponsored the state's RAISE Act on AI safety, in the Democratic primary for the 12th congressional district, where the Anthropic-funded Public First Action backed him.¹²¹³
