- Chris Malone, OpenAI's head of data centers, departed last week per the Wall Street Journal, shortly after joining in March 2024 from a career spanning nearly five years at Meta and over a decade at Google.
- OpenAI said it "recently reorganized" its infrastructure organization; Malone had stopped reporting directly to President Greg Brockman and began reporting to VP Sachin Katti, with Uday Ruddarraju, Brent Mayo, and Spas Lazarov also overseeing data center work.
- The Malone exit is part of at least 13 executive departures in 2026 per Business Insider, including CRO Denise Dresser (replaced after eight months), longtime COO Brad Lightcap, and de facto second-in-command Fidji Simo, who cited chronic illness.
- OpenAI's safety apparatus has also thinned: the company lost head of ethics Chloé Bakalar in July and disbanded its preparedness team, a unit dedicated to assessing catastrophic AI risks, last week.
- The churn comes as OpenAI's IPO — originally expected this year — has been pushed to 2027, with the source noting concerns about overvaluation and whether profitability matches the lab's gargantuan infrastructure investments.
- Greg Brockman attributed the scrutiny to OpenAI's intense "spotlight," saying "every departure gets scrutinized in a way that it doesn't otherwise," even as Malone's role grew more critical following the Stargate Project, a data center initiative involving Oracle, Nvidia, SoftBank, and Microsoft.
Why it matters: The timing compounds doubts about OpenAI's IPO readiness: the 2027 listing arrives amid open questions about whether profitability matches the lab's gargantuan infrastructure spend, and losing the executive running data center execution during the Stargate buildout removes institutional knowledge at the moment that scale matters most — while Safety roles and C-suite bench depth thin in parallel.
