This former notorious red-light district is now one of the world’s top AI hubs
↗
London's King's Cross has transformed from a notorious red-light district into one of the world's top AI hubs, anchored by DeepMind's 2016 arrival and now hosting major labs including OpenAI, Anthropic, and Meta, with office vacancy at 0.9% and prime rents up 18% over three years.
The concentration of AI talent and capital in King's Cross creates a self-reinforcing cluster effect, but the Anthropic shutdown of Mythos and Fable access this summer exposed a sovereignty risk: Europe cannot simply rent AI capabilities from US labs. The practical question for builders is whether the UK will develop the compute, energy, and capital infrastructure to make self-reliance durable, or remain dependent on outposts of American companies.

King's Cross has become a global AI hub rivaling San Francisco and Beijing, with around 3,600 AI startups in London that have raised approximately $12.1 billion, and AI-related startups leasing over 1 million square feet of office space since early June.
Office space in King's Cross is extremely scarce and expensive, with a vacancy rate of just 0.9% for conventional space and prime rents rising 18% over the past three years for large leases, with shorter deals costing even more.
Anthropic's shutdown of Mythos and Fable access this summer prompted investors and founders to confront Europe's dependency on US AI labs, raising questions about whether the UK will build sovereign infrastructure or just host American outposts.
