Brad Lightcap, chief operating officer of OpenAI, announced on Tuesday (11) his departure from the company, after eight years of work, to start a new venture. The departure comes amid a series of leadership changes at the artificial intelligence developer, which is weighing going public.
In a post on X, Lightcap described the decision as 'bittersweet' and said the years spent building the company were the honor of his life. He also said the company kept its focus on people and that he hopes to continue earning users' trust.
Lightcap joined OpenAI in 2018 and spent four years as chief operating officer. He helped structure the areas of finance, legal, human resources, corporate security, government relations and partnerships, during the period in which the company went from being a research laboratory to becoming one of the leading AI developers.
Leadership changes
Before Lightcap, other executives left OpenAI in 2026. In April, Bill Peebles, Kevin Weil and Srinivas Narayanan announced their departures. In July, Fidji Simo, head of products and business, resigned to treat a chronic illness, and Chloé Bakalar, AI ethics leader, also left, with no replacement announced. In the same month, Johannes Heidecke, head of safety systems, and Joshua Achiam, chief futurist, left the company.
OpenAI filed a confidential request for a possible IPO in June, but did not say whether or when it will proceed. On the Myriad prediction market, the chance that rival Anthropic will go public before OpenAI is nearly 85%.
Jeff Park, a partner at asset manager ParaFi, wrote on X that it is not common for so many executives to leave before an IPO, followed by 'Unless...'. Lightcap said he will remain available to support colleagues after his departure.
