A number of US Big Tech and AI companies are vying to expand in London, hoping to tap into the city’s rich talent pool as they drive the development and commercialization of frontier technologies.
Anthropic and OpenAI have both announced they have taken up larger office space in the UK capital in recent months.

“It’s all about talent,” Mike Wiseman, British Land’s campus director, told CNBC. “London has built a deep and mature technology ecosystem over the years. If you’re looking to expand your business internationally, London is one of the few markets in the world that can support that level of growth.”
Rich talent pool
Mr Wiseman said demand from technology companies was returning to London after a quiet period following the pandemic. This is being driven by a new generation of companies that were not in the spotlight just a few years ago.
Record funding levels over the past few years have fueled growth in the global AI sector as investors rush to back companies developing the technology. Startups around the world have raised $392.1 billion so far this year, according to Dealroom, already dwarfing the all-time record set in 2025, when companies raised $215.9 billion.
Frederick Grosols, a partner at executive search firm Heidrick & Struggles, told CNBC that London is emerging as one of the “deepest” pools of frontier AI talent outside the United States.
“A decade of investment by DeepMind, leading research institutions, and leading universities has created a mature talent base spanning AI research, engineering, and commercial leadership.”
DeepMind was founded in London in 2010 and was acquired by Google in 2014, but kept a large team in the UK capital. Google DeepMind has since powered the tech giant’s Gemini model, along with numerous breakthroughs in AI.
When announcing Anthropic’s London expansion in April, securing office space for 800 people, roughly four times the number of employees in London, Pip White, head of EMEA North, specifically highlighted an “outstanding AI talent pool” as a key driver of the move.
Anthropic’s new office space will feature OpenAI, Google DeepMind, MetaSynthesia and Wave.
London is also one of the world’s major financial centers, giving companies “ready access to venture, growth stocks and corporate development networks,” Grosols added.
Dan Hyde, executive chairman and founder of executive search firm Elevena, said all this activity in the London market by deep-pocketed US tech companies is putting pressure on local startups and making it harder to recruit top talent. “These (U.S.) companies are in a position to offer attractive packages (cash and stock) and meaningful work. Many people want to work for them.”

Space is a major constraint for London’s technology sector.
“London’s biggest structural challenge at the moment is supply,” Wiseman said. “There is a well-documented shortage of high-quality office space in the coming years, especially in core locations, and this is likely to continue until 2030.”
British Land estimates there will be a 10.4m sq ft shortfall in new or significantly refurbished space across London by 2030.
The shortage is being driven by fast-growing AI companies competing with more traditional financial and professional services companies for the same limited inventory in top offices, Groussolles added.
Beyond office space, concerns are emerging about whether the infrastructure needed to support employees and rapidly increasing computing demands will continue to keep pace with growth.
“The bigger question is whether to continue investing in the infrastructure that supports growth, people, power, housing, transportation and computing,” said Ziv Reichert, a partner at London-based VC firm Local Globe.
He added: “Talent has brought the institute to London, but keeping it here will depend on Britain building the infrastructure around it.” “Computing, energy and capital are just as important as researchers.”
