OpenAI's Data Center Chief Exits Amid Leadership Churn

The revolving door at OpenAI’s executive suite has swung again, this time catching the person responsible for building the infrastructure that underpins the company’s AI ambitions.

Chris Malone, OpenAI’s head of data centers, left the company last week, according to a report from the Wall Street Journal. Malone’s departure is the latest in a series of high-profile exits that has raised questions about the company’s stability as it prepares for a potential IPO.

A Short Tenure at a Critical Post

Malone joined OpenAI in March of last year, making his time at the company relatively brief. Before that, he spent nearly five years at Meta and more than a decade at Google. His background in scaling large-scale infrastructure made him a natural fit for the data center role, which has become one of the most closely watched positions in the AI industry.

He arrived shortly after the launch of the Stargate Project, a $500 million data center initiative championed by the Trump administration. OpenAI, along with Oracle, Nvidia, SoftBank and Microsoft, is a key partner in the effort, which aims to develop data centers across the U.S.

The reasons for Malone’s exit remain unclear. In a statement to TechCrunch, OpenAI said it had “recently reorganized” its “infrastructure organization to support the scale and pace of our work.” The company added: “We have a strong, deeply experienced data center team in place, with clear leadership and the technical expertise to execute our plans.”

Reorganization Shifts Reporting Lines

As part of that reorganization, Malone stopped reporting directly to OpenAI President Greg Brockman and began reporting to Vice President Sachin Katti, who took over leadership of the group, per the WSJ.

Other executives are now overseeing different parts of the data center strategy. Uday Ruddarraju leads the company’s data center team. Brent Mayo leads the data center build and delivery program. Spas Lazarov, a veteran of the data center and energy industries, leads all data center engineering.

“We have a strong, deeply experienced data center team in place, with clear leadership and the technical expertise to execute our plans.”

A Wave of Departures

Malone is not alone. Business Insider recently tallied the total 2026 departure count at 13, with several executives leaving in just the last month. These are not junior employees; they are some of the company’s most senior leaders.

Two weeks ago, the company replaced its chief revenue officer, Denise Dresser, after she had been with the company for only about eight months. Two days before Dresser’s departure, the company also lost Brad Lightcap, its longtime chief operating officer, who said he would be “starting something new” but has not given details.

About a month earlier, the company also lost Fidji Simo, its de facto second-in-command, who served as product and business chief and reported directly to CEO Sam Altman. She stepped down to recover from a “chronic illness” and remains with the company in an advisory role.

Safety and Ethics Teams Hit Too

OpenAI’s safety and ethics teams have seen notable departures as well. In July, the company lost its “head of ethics,” Chloé Bakalar. Last week, it was reported that the company had disbanded its preparedness team, a unit dedicated to assessing whether the company’s AI models could result in catastrophic risks.

Other team leaders have left because their projects were shut down. Bill Peebles, the former head of OpenAI’s now-defunct AI image generator Sora, is one such example. In April, the company also lost its chief marketing officer, Kate Rouch, who—like Simo—reportedly left for health reasons.

Leadership Tries to Downplay the Churn

OpenAI’s remaining talent has tried to minimize the significance of the ongoing talent flight. Co-founder Greg Brockman recently lamented that the intense “spotlight” on the company means that “every departure gets scrutinized in a way that it doesn’t otherwise.”

But the churn has naturally raised questions, especially as the company prepares for an IPO. OpenAI’s public listing, originally expected this year, is now reportedly pushed to 2027. The company is undergoing a kind of reputational vetting that comes with any looming listing. Concerns have arisen that the company may be overvalued and that its profitability doesn’t match the gargantuan investments being made in the lab.

Why It Matters

The stream of executive departures could have real consequences for OpenAI’s ability to execute its infrastructure plans. With the Stargate Project requiring massive coordination among partners, a stable leadership team is critical.

The push of the IPO to 2027 suggests the company is facing scrutiny over its valuation and profitability. The ongoing talent flight may only amplify concerns among potential investors.

For a company that has become synonymous with AI’s rapid rise, the revolving door at the top could signal instability at a time when OpenAI needs to demonstrate it can deliver on its promises—both to its partners and to the market.
