OpenAI Data Center Chief Chris Malone Exits as 2026 Departures Hit 13
OpenAI data center chief Chris Malone exits amid a 2026 executive exodus, infrastructure overhaul and a reported IPO delay until 2027 as scrutiny intensifies.
Summary
Chris Malone, OpenAI’s head of data centers, left in the week before August 26, 2026, after joining in March 2025; his reason remains unclear. He previously spent nearly five years at Meta and more than a decade at Google. Malone oversaw data center strategy after the $500 million Stargate Project launched with Trump administration backing and OpenAI, Oracle, Nvidia, SoftBank and Microsoft as key partners. Following an infrastructure reorganization, he stopped reporting to President Greg Brockman and reported to Vice President Sachin Katti, who assumed group leadership. Uday Ruddarraju leads the data center team, Brent Mayo runs build and delivery, and data center and energy veteran Spas Lazarov leads engineering. OpenAI says the reorganization supports its scale and pace and that an experienced team remains.
Malone’s exit brings reported 2026 executive departures to 13, with several in the past month. OpenAI replaced chief revenue officer Denise Dresser two weeks earlier after about eight months; longtime chief operating officer Brad Lightcap left two days before that announcement to start an undisclosed project. Roughly a month earlier, product and business chief Fidji Simo, CEO Sam Altman’s direct report and de facto deputy, stepped down over chronic illness but remained an adviser. Ethics head Chloé Bakalar left in July; chief marketing officer Kate Rouch departed in April for reported health reasons; Bill Peebles left after Sora, the image generator he led, was shut down; and OpenAI disbanded its preparedness team, which assessed catastrophic model risks, last week. Brockman says OpenAI’s spotlight amplifies scrutiny of each exit. The churn intensifies questions about safety, valuation and profitability ahead of an IPO reportedly delayed from 2026 to 2027 despite enormous investment.
