OpenAI secures first permanent London office with capacity for more than 500 staff

OpenAI is moving to its first permanent London office, a larger site that will more than double its UK headcount capacity.

Reuters-syndicated and trade reporting say the new office is expected to open in 2027 and will hold more than 500 staff. The move follows OpenAI’s earlier London presence and marks a deeper commitment to the UK market.

OpenAI previously said London would become its largest research hub outside the United States. The company opened its first international office in London in 2023 and has since expanded its local team.

The permanent-office move signals continued investment in the UK as OpenAI grows its research and business operations outside the U.S. The exact building has not been formally detailed in the available reporting.

No standalone OpenAI statement on the lease was included in the reports reviewed, but multiple outlets said the move is now confirmed.
