OpenAI Expands London Presence With New Office
OpenAI opened its first permanent office in London, expanding its international operations. The site spans 88,500 square feet in King’s Cross and is designed to accommodate more than 500 employees. The expansion follows a decision to pause a planned U.K. infrastructure project, according to CNBC.
Strategic Investment In London
OpenAI plans to scale its London operations as a key research center outside the United States. The company currently employs около 200 staff in the city, with hiring expected to increase. Phoebe Thacker, London Site Lead at OpenAI, said the U.K. offers a strong talent base and an established AI research ecosystem. The new office is intended to support continued team growth.

Navigating U.K. Energy And Regulatory Challenges
The expansion comes alongside a pause in OpenAI’s U.K. Stargate project, linked to high industrial energy costs and regulatory constraints. Discussions with project partner Nscale are ongoing. Industry observers note that industrial energy prices in the U.K. remain among the highest globally, affecting the economics of large-scale AI infrastructure.
The U.K.’s Ambitious AI Strategy
The U.K. government launched its AI Opportunities Action Plan in early 2025, contributing to increased investment activity. Venture funding in the sector reached $6.7 billion during the year. Recent deals include $2 billion raised by Nscale, $1.2 billion by Wayve, and $500 million by ElevenLabs. These investments reflect continued interest in AI infrastructure, autonomous systems, and voice technologies.
