OpenAI Computing Chief to Depart

OpenAI’s head of computing capacity is leaving the company next month after about a year, the latest leadership change at a unit driving hundreds of billions of dollars of investment in the coming years.

Sachin Katti joined OpenAI in late 2025 to rein in its ambitious Stargate data center effort, which got off to a slow start after the company failed to reach a deal with SoftBank and Oracle. Instead, OpenAI forged deals with the firms separately, and Katti struck additional computing agreements with providers such as Amazon Web Services to shore up OpenAI’s capacity.

Katti also worked to revive OpenAI’s plans to lease its own data centers, rather than rent capacity from other providers. In August he helped lock in a 10-gigawatt data center lease with SB Energy that came with a financial guarantee from Nvidia.

OpenAI plans to inform employees about the departure on Wednesday, and Katti is expected to stay on as an adviser, according to people familiar with the matter.

The artificial-intelligence company is among the technology giants spending gargantuan sums on vast data center projects needed to continue powering their products. Securing enough computing power can be key to a company’s commercial success.

OpenAI raised its projected spending on computing power to around $750 billion through 2030, up from a projection of roughly $600 billion earlier in the year. The company is in a heated race for users with rival Anthropic and both companies are preparing for upcoming IPOs.

Former xAI executive Uday Ruddarraju, who was promoted to chief technology officer of computing capacity at OpenAI this summer, is now set to take over the company’s computing strategy. He reports to President Greg Brockman.

Another executive overseeing OpenAI’s data-center build-out left the company over the summer.
