Chris Malone stepped down as OpenAI’s head of data centers after about a year and a half in the role. TechCrunch reported the exit on August 25, noting that the Wall Street Journal had broken the news first. What makes the story worth a second look isn’t the resignation itself. It’s how OpenAI carved up the position he left behind.
Nobody simply slid into Malone’s chair. Per TechCrunch, OpenAI restructured its infrastructure group, and by the time Malone left he was already answering to vice president Sachin Katti rather than president Greg Brockman. Three people now cover the ground Malone once owned alone: Uday Ruddarraju runs the data center team, Brent Mayo handles build and delivery, and Spas Lazarov oversees data center engineering. One construction-heavy job has turned into three distinct functions.
OpenAI told TechCrunch it had “recently reorganized” its “infrastructure organization to support the scale and pace of our work,” adding that it has “a strong, deeply experienced data center team in place, with clear leadership and the technical expertise to execute our plans.” The company offered no explanation for why Malone specifically is gone, and his next move hasn’t surfaced publicly. That gap is worth sitting with instead of guessing at: a company this size rarely spells out why a single executive walks, and an unexplained exit on its own proves nothing about the cause.
A second, separately reported thread looks more consequential: OpenAI is said to be reversing course on how it gets new capacity, favoring leases on already-built facilities over ground-up construction, with a different group of executives now steering that shift instead of Malone. Building from scratch means securing land, clearing permits, waiting in line for grid connections, and locking in multi-year contracts, the approach behind Stargate, the Oracle and SoftBank partnership whose showcase site sits outside Abilene, Texas. Leasing skips most of that: someone else already financed and wired the building, which turns a construction problem into a procurement one and hands the risk to a different set of partners.
The mismatch matters because Malone joined in March 2025 with a mandate to build, not lease. If leasing is where OpenAI is now putting its weight, the role he accepted a year and a half ago has quietly become a different job. Splitting his old seat three ways looks less like a promotion pipeline and more like a company keeping both options open rather than picking a lane.
Malone’s departure adds to a run of more than a dozen senior exits at OpenAI this year, a figure Business Insider has counted at 13. Chief revenue officer Denise Dresser left after only eight months on the job. Longtime chief operating officer Brad Lightcap exited saying only that he planned on “starting something new.” Product and business chief Fidji Simo stepped back into an advisory role while she deals with an ongoing health issue. And the company’s head of ethics departed in July, around the time OpenAI shut down the team responsible for screening its models for catastrophic risks. Brockman has argued the pattern is overread, saying “every departure gets scrutinized in a way that it doesn’t otherwise” given how closely the company is watched.
What separates this wave from ordinary turnover is the calendar. An IPO that OpenAI once penciled in for this year has reportedly slipped to 2027, and companies heading toward a listing typically swap out leaders until the bench matches whoever needs to sign the disclosures a public filing demands. A data center program leans on multi-year ties to utilities, grid operators and builders that don’t reset cleanly when an org chart does, unlike a sales seat that can be refilled in a quarter.
For anyone watching OpenAI’s infrastructure bets ahead of a 2027 listing, two things to track: who fills the still-unnamed technology executive role overseeing computing capacity, and whether the announced sites in Abilene, Georgia and Ohio hold their public timelines. Eventually a prospectus will force OpenAI to spell out key-person risk and compute commitments in writing, and the length of that list will say more than any single resignation does.
Based on TechCrunch (Lucas Ropek, August 25, 2026), which first reported OpenAI’s confirmation of the departure.
