OpenAI announces first permanent London office
OpenAI has recently unveiled plans to establish its inaugural permanent office in London, accommodating over 500 team members. This decision follows the company’s suspension of a major AI infrastructure project in the United Kingdom.
The U.S.-based AI organization confirmed the signing of a lease for an expansive 88,500 square foot space earlier this week. In February, OpenAI declared that London would serve as its primary research center outside of the U.S. Presently, the company has approximately 200 employees in the British capital.
Phoebe Thacker, the London site lead at OpenAI, expressed, “The UK possesses an exceptional pool of talent and a distinguished history in AI. London already serves as a pivotal hub for our research and teams, and this new office will provide us with the necessary room to continue expanding.”
Situated in the King’s Cross vicinity of London, OpenAI’s new office will be surrounded by various AI enterprises, including Google DeepMind, Meta, Synthesia, and Wayve.
This development comes shortly after OpenAI confirmed the suspension of its U.K. Stargate initiative, citing high energy costs and regulatory challenges within the country.
Although discussions between OpenAI and its project partner, Nscale, are ongoing, the decision to pause the project was perceived as a setback for the U.K.’s AI advancement.
Industrial energy prices in the U.K. rank among the highest globally. Critics have previously highlighted the exorbitant energy costs and grid access delays as significant impediments to the nation’s AI infrastructure expansion.
The UK’s AI Strategy
The United Kingdom has been striving to establish itself as a prominent global AI hub, albeit trailing behind leading ecosystems such as the U.S. and China in terms of technological innovation and funding.
At the beginning of 2025, the country launched its AI Opportunities Action Plan, with AI startups increasingly securing substantial funding from venture capitalists.
To date, funding in the AI sector has reached $6.7 billion this year, as reported by Dealroom, nearing the $8.2 billion recorded for the entirety of 2025.
In March, AI cloud company Nscale secured $2 billion, while autonomous driving startup Wayve received $1.2 billion in February, and AI voice startup ElevenLabs raised $500 million.
Following the dispute between the Pentagon and OpenAI competitor Anthropic, U.K. officials intensified efforts to attract the company, proposing office expansion in London and a dual listing, as reported by the Financial Times earlier this month.
