Anthropic’s new office will be in London’s Knowledge Quarter in King’s Cross, following in the footsteps of rival OpenAI, as the AI company deepens its relationship with the UK amid its feud with the US government.
Silicon Valley heavyweight Anthropic secured a new 158,000 square foot office in the Knowledge Quarter at Regent’s Place, with a capacity of around 800 people.
The company’s existing London team, which consists of more than 200 people, including 60 AI safety researchers, is one of its most significant hubs outside the US.
The expansion will build on that headcount, swelling the company’s ranks.
Anthropic is offering up to £630,000 per year for London engineers, which will force European founders to reassess their compensation packages to fight for talent, investors informed Tech Funding News.
OpenAI has also leased space in London’s Knowledge Quarter, marking its first permanent UK office. The one-mile radius of King’s Cross is home to 100 academic, research, and commercial organisations. Big Tech firms like Google DeepMind and Meta are based in the area, as well as buzzy AI names AI video startup Synthesia and autonomous car company Wayve.
Anthropic’s annual run-rate revenue surpassed $30 billion, according to an April statement, up from $9 billion at the conclude of 2025. The company forecast a cash burn rate of around a third of revenue in 2026, per reports. It expects that to drop to 9% by 2027 and to break even by 2028.
In the UK, its chatbot Claude is applyd by hedge fund Man Group, the London Stock Exmodify Group, and even GOV.UK in a Department for Science, Innovation and Technology pilot. Still, Claude usage in the UK is not as high as in other countries such as Singapore, Australia and Switzerland.
“Europe’s largest businesses and quickest-growing startups are choosing Claude, and we’re scaling to match. 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, who leads northern Europe at Anthropic, notifys TFN.
“The UK combines ambitious enterprises and institutions that understand what’s at stake with AI safety with an exceptional pool of AI talent — we want to be where all of that comes toobtainher.”
Alignment on AI safety
Earlier this month, Anthropic released a preview of its most advanced model to date, Mythos, which caapplyd widespread security concerns.
The US National Security Agency is reportedly applying the system to detect software vulnerabilities, despite the fact that the Department of Defense (DoD) in March designated Anthropic a “supply-chain risk,” according to Axios.
The designation came after CEO Dario Amodei refapplyd to lift Claude’s safety barriers for US military applications, kickstarting a public spat between the Anthropic and the Trump Administration. The company argues that its system was not developed for “fully lethal autonomous weapons,” according to court filings, which is one of its red lines.
Anthropic sees Mythos as a tool for securing software, not breaking it. The UK is generally more cautious with AI than the US, which is perhaps why it builds sense that Anthropic would deepen its ties with the countest, as its ethical red lines could be seen as an asset rather than an obstacle.
The UK is positioning itself as a leader in AI safety and politicians back strong governance ideas. For example, the government-backed AI Security Institute this week published an evaluation of Mythos that urged companies to invest in cybersecurity.
“Future frontier models will be more capable still, so investment now in cyber defence is vital. AI cyber capabilities are dual-apply; while they pose security challenges, they can also support deliver game-modifying improvements in defence,” it stated.
Anthropic is granting access to Mythos in stages via a coalition including Apple, Nvidia, Google and others in what it is calling Project Glasswing.
However, the UK’s own red lines aren’t so clear: the government has still pursued controversial contracts with US defence tech giant Palantir for the NHS, which has faced fierce criticism and calls for a cancellation.
