London AI expansion and talent demand

Highlights

Anthropic and OpenAI have expanded office space in London, while Cursor will open a headquarters this summer and Google will soon relocate teams to a new 11-storey Kings Cross building.
Accelerating U.S. tech group demand is intensifying competition for AI talent and premium office space, with British Land projecting a 10.4 million square foot office shortfall by 2030.
London's deep AI talent pool, boosted by DeepMind and university investments, continues to drive U.S. firm expansion but adds pressure on local startups and infrastructure.

Talent pipeline drives London office growth

As reported by CNBC, several U.S. technology companies are enlarging their presence in London as they seek access to the city’s established pool of AI researchers, engineers and commercial staff. Anthropic and OpenAI have recently taken larger office space in the capital, while Cursor says it plans to open a London headquarters this summer and Google says it will start moving teams into a new 11-storey building in Kings Cross in the coming months.

Other U.S. software companies, including Databricks and Salesforce, are also increasing headcount or expanding their campuses in the city. Rivian and Palantir say in the second half of 2025 that they are also growing in London.

Mike Wiseman, head of campuses at British Land, says London has built a deep and mature technology ecosystem over many years and remains one of the few markets able to support global scaling. Frederic Groussolles, a partner at Heidrick & Struggles, says the city now offers one of the deepest pools of frontier AI talent outside the U.S., supported by years of investment from DeepMind, research labs and universities.

That talent base has been strengthened by DeepMind’s long-standing presence in the city after Google acquired the company in 2014. When Anthropic announced its London expansion in April, including office space for 800 people, Pip White, head of EMEA north, pointed to the capital’s exceptional AI talent pool as a main reason for the move.

Hiring and infrastructure pressures build

Growing interest from heavily funded U.S. companies is also increasing strain on London’s startup ecosystem. Dan Hyde, executive chair and founder at Erevena, says the larger groups can offer strong cash and equity packages as well as high-profile work, making recruitment harder for local companies.

Office capacity is emerging as another constraint. Wiseman says London faces a shortage of high-quality office supply in core locations over the next few years, and British Land estimates a 10.4 million square foot shortfall of new or substantially refurbished space by 2030.

Groussolles says fast-growing AI companies are competing with finance and professional services firms for the same premium offices. Ziv Reichert, partner at LocalGlobe, says London’s longer-term ability to retain AI labs depends not only on talent, but also on continued investment in power, housing, transport, compute capacity and capital.

Our earlier article on OpenAI’s potential AI price cuts explained that the company was weighing a significant reduction in token pricing to compete more aggressively with Anthropic and win users. We also noted that the broader AI race is increasingly shaped not just by model quality, but by distribution advantages and scaling strategies among major players.
