What happened

Anthropic said Thursday it's expanding its presence in London with new office space for 800 people, days after rival OpenAI unveiled plans for its first permanent office in the U.K.

Why it matters

The maker of the Claude AI chatbot currently has more than 200 people based in London, the company said in a statement.

Common ground

"London is already one of our most important research and commercial hubs outside the US, and our expansion in the Knowledge Quarter gives us the room to grow into," Pip White, Anthropic's head of EMEA north, said in a statement.

Perspective signals
