In November 2023, OpenAI's board removed Sam Altman as chief executive officer, citing a lack of confidence in his leadership. The decision triggered a swift and public backlash from employees and investors, leading to Altman's reinstatement five days later following a reconstruction of the board. The episode became a defining moment in the governance of leading artificial intelligence companies, highlighting tensions between commercial growth and nonprofit mission oversight.
The crisis unfolded against the backdrop of OpenAI's rapid expansion after the release of ChatGPT in November 2022, which accelerated the AI boom. By 2023, OpenAI had become a central player in the generative AI industry, with major investments from Microsoft and partnerships across the technology sector. The board's action on November 17, 2023, was unexpected, as Altman had been widely seen as the public face of the company and a leading advocate for AI development.
Background and Board Composition
OpenAI was founded in December 2015 as a nonprofit organization by Elon Musk, Sam Altman, Ilya Sutskever, Greg Brockman, Trevor Blackwell, Andrej Karpathy, John Schulman, and Wojciech Zaremba, among others. The initial mission was to ensure that artificial general intelligence (AGI) benefits all of humanity. In 2019, OpenAI transitioned to a "capped" for-profit structure, creating a subsidiary that could attract investment while the nonprofit retained control. The board of the nonprofit OpenAI, Inc., had formal fiduciary responsibility to the charter, and a majority of its members were barred from having financial stakes in the for-profit entities.
By November 2023, the board consisted of six members: Altman, Brockman, Sutskever, Adam D'Angelo, Tasha McCauley, and Helen Toner. Sutskever, the chief scientist, was a co-founder and had been instrumental in the company's technical direction. D'Angelo was the CEO of Quora, McCauley was a technology executive, and Toner was a researcher at Georgetown's Center for Security and Emerging Technology. The board's composition reflected a mix of technical expertise and AI governance perspectives, but it lacked direct representation from major investors like Microsoft.
The Firing and Immediate Reactions
On November 17, 2023, the board announced that Altman would step down as CEO, with the statement citing that he "was not consistently candid in his communications with the board." The board named Mira Murati, then chief technology officer, as interim CEO. Altman's removal was met with shock across the industry. Microsoft, which had invested over $13 billion in OpenAI, was reportedly blindsided. Greg Brockman, the president and co-founder, resigned in protest shortly after the announcement.
The decision was widely interpreted as a clash between the nonprofit's safety-focused ethos and the commercial pressures of scaling large language models. Sutskever, who had been a proponent of AI safety research, was seen as a key figure in the ouster. However, the lack of transparency about the board's specific concerns fueled speculation and criticism.
Employee Backlash and the Letter
Within days, a majority of OpenAI's roughly 770 employees signed an open letter demanding Altman's reinstatement and the resignation of the board. The letter, released on November 20, threatened that signatories would "resign and join Sam Altman at a new subsidiary of Microsoft" if the board did not step down. The signatories included Sutskever, who had initially supported the firing but later reversed his position, as well as other senior researchers like John Schulman and Wojciech Zaremba.
The employee revolt was unprecedented in the tech industry. It highlighted the deep loyalty Altman commanded and the belief among staff that his leadership was essential to OpenAI's mission and momentum. The letter also underscored the influence of Microsoft, which had the resources to absorb a mass exodus of OpenAI talent.
Negotiations and Interim Leadership
Following the letter, negotiations began to bring Altman back. The board initially resisted, appointing Emmett Shear, co-founder of Twitch, as interim CEO on November 20. Shear's appointment was seen as a compromise, but it did not quell the unrest. Microsoft CEO Satya Nadella publicly stated that Altman would lead a new AI research team at Microsoft if he did not return to OpenAI, adding to the pressure.
Over the next two days, intense discussions involved Altman, Brockman, Nadella, and board members. Reports indicated that the board was divided, with some members willing to resign if Altman returned. The key sticking point was the board's demand for governance reforms that would prevent future conflicts and ensure the nonprofit's mission remained central.
Altman's Return and Board Reconstruction
On November 22, 2023, OpenAI announced that Altman would return as CEO, and the board would be reconstituted. The new initial board comprised Adam D'Angelo, Bret Taylor, and Larry Summers. D'Angelo remained from the previous board, while Taylor, a former Salesforce co-CEO, and Summers, a former U.S. Treasury Secretary, were new additions. The reconstituted board was tasked with overseeing an independent review of the events and ensuring the company's governance aligned with its mission.
Altman's reinstatement was widely seen as a victory for employees and investors, but it also raised questions about the board's independence. The new board had no members with explicit AI safety backgrounds, and Microsoft, while not given a board seat, was reported to have influenced the outcome. The episode led to calls for clearer governance frameworks in AI companies, especially those with hybrid nonprofit-for-profit structures.
Aftermath and Impact
The crisis had lasting effects on OpenAI and the broader AI industry. In the following months, several key researchers departed, including Sutskever, who left in 2024 to found Safe Superintelligence Inc., and John Schulman, who joined Anthropic. The episode also intensified debates about AI safety and the balance between rapid deployment and precautionary measures.
For the industry, the crisis served as a cautionary tale about the fragility of governance in AI organizations. It prompted discussions about the role of nonprofit boards, the influence of corporate partners, and the need for transparent decision-making. The event was also a factor in the Bletchley Declaration and other international efforts to address AI risks, as governments and regulators took note of the volatility at one of the sector's leading firms.
Legacy and Ongoing Governance Reforms
In the years following the crisis, OpenAI implemented various governance changes, including the 2025 restructuring that converted its for-profit subsidiary into OpenAI Group PBC, a public benefit corporation. The nonprofit OpenAI Foundation retained a 26% ownership stake, and the board was expanded to include members with diverse expertise. However, the November 2023 events remained a reference point for discussions about accountability in AI development.
The crisis also influenced how other AI companies structured their boards and decision-making processes. Anthropic, for example, adopted a long-term benefit trust to oversee its governance. The episode underscored the tension between the profit motives of investors and the stated mission of benefiting humanity, a tension that continues to shape the AI boom and the trajectory of generative AI technologies.
