BroadChain has learned that OpenAI has put its Stargate infrastructure project in the UK on hold, CNBC reported on April 9. The decision is primarily attributed to skyrocketing energy costs and an uncertain regulatory landscape.
First announced in September 2025, the Stargate project was a collaboration with Nscale and Nvidia, aiming to deploy up to 8,000 GPUs. The initiative is now paused indefinitely.
An OpenAI spokesperson confirmed the pause, stating the company is still assessing the conditions needed to advance the project. They emphasized that progress will resume only when the regulatory environment and energy costs become more conducive to long-term infrastructure investment.
This follows a major restructuring of OpenAI's Stargate computing initiative last month. The company abandoned plans to build its own data centers, opting instead to rely on third-party cloud services like AWS and Google Cloud for compute capacity. Consequently, its projected total compute spending by 2030 has been revised down from $1.4 trillion to roughly $600 billion.
