Anthropic snaps up London office for 800, days after OpenAI plants its flag

Big move in the Knowledge Quarter

Anthropic said Thursday it has leased new office space in London’s Knowledge Quarter that can accommodate up to 800 people, just days after rival OpenAI unveiled its first permanent U.K. office. The AI startup, maker of the Claude chatbot, currently employs more than 200 people in London, the company said — and Pip White, Anthropic’s head of EMEA north, called the city “one of our most important research and commercial hubs outside the US.” Ambition? Clearly. Pace? Blistering.

Politics, poaching and proximity

The new site sits amid an AI neighborhood crowded with OpenAI, Google DeepMind, Meta, Synthesia and Wayve. It has been reported that U.K. officials actively courted Anthropic after the company’s public spat with the U.S. Pentagon — part charm offensive, part strategic play to anchor AI talent in Britain. Rivalry is no longer just about models and benchmarks; it’s about offices, talent pipelines and geopolitical optics. Who gets the turf matters.

Momentum, numbers and market noise

Anthropic has been pushing products lately — think Claude Code for coding and the Mythos model that flags software security weak spots — and it’s riding headlines. That said, it has been reported that the firm raised $30 billion at a $380 billion valuation in February, and that VCs have floated investments valuing the company as high as $800 billion; it has also been reported that its annual run-rate revenue has surpassed $30 billion with more than 1,000 customers each spending over $1 million annually. Take those figures with a grain of salt until independently verified. Still: expansion like this signals confidence. London just got a louder seat at the global AI table — and the next chapter? Should be interesting.
