Chris Malone, OpenAI’s former data center chief, has left the company after joining in March 2025 from Meta Platforms and Google, sharpening focus on leadership of its fast-growing infrastructure buildout. OpenAI said it recently reorganized its infrastructure organization to support the scale and pace of its work and that a strong, experienced data-center team remains in place. Internal reporting lines shifted so Malone no longer reported to Greg Brockman, with Sachin Katti taking leadership of the group alongside leaders including Uday Ruddarraju, Brent Mayo, and Spas Lazarov. The move adds to more than a dozen 2026 executive exits tallied at 13 by Business Insider, including the replacement of Chief Revenue Officer Denise Dresser by Dali Rajic, the departure of COO Brad Lightcap, Product and Business Chief Fidji Simo’s step-down for a chronic illness while she continues to advise, and turnover tied to safety and governance such as the July exit of Ethics Lead Chloé Bakalar and the disbanding of the preparedness team focused on catastrophic-risk evaluation. OpenAI confidentially filed draft IPO paperwork with U.S. regulators and has been working toward a public debut, though subsequent reports suggest it could wait until 2027 as it weighs market conditions against a reported $1 trillion valuation goal.
