OpenAI computing chief Sachin Katti set to leave in November 2026

In his announcement, Katti said OpenAI secured double-digit gigawatts of computing capacity across projects in Ohio, Portsmouth and Georgia, along with Trainium and other efforts. He named Nvidia, Broadcom, AMD, Oracle, Microsoft, Google, AWS and CoreWeave among the company’s partners.

Katti also said his team got “GPT-Infra” running in three months. The Journal reports that he joined OpenAI in late 2025 to rein in the Stargate data center effort and later helped secure a 10-gigawatt lease with SB Energy in August, backed by a financial guarantee from Nvidia.

The handoff comes as compute spending climbs

The leadership change lands as OpenAI commits enormous sums to data centers and cloud capacity. The Journal says the company raised its projected compute spending to about $750 billion through 2030, up from roughly $600 billion earlier in 2026.

That scale makes the infrastructure job central to OpenAI’s attempt to keep expanding its models and products. Katti did not identify his next venture, writing only that he plans to bring together what he has learned across the computing stack.
