A slew of U.S. Huge Tech and AI corporations are racing to increase in London as they appear to make the most of town’s deep expertise swimming pools amid a push to develop and commercialize frontier tech.
Anthropic and OpenAI each introduced they’d taken up bigger workplace areas within the U.Ok. capital in latest months. Vibe coding platform Cursor unveiled plans this week to open a London headquarters this summer season and Google mentioned it is going to start transferring groups into a brand new 11-storey constructing in Kings Cross within the coming months.

Deep expertise swimming pools
After a quiet post-pandemic interval, demand from tech corporations has returned in London, Wiseman mentioned. That is being pushed by a “new technology” of corporations that weren’t on the radar just a few years in the past.
Development within the international AI sector has been fuelled by document funding figures over the previous couple of years, as buyers have rushed to again corporations growing the tech. Startups globally have raised $392.1 billion to date this yr, in line with Dealroom, already dwarfing the earlier document yr of 2025, when corporations secured $215.9 billion.
London has emerged as one of many “deepest” swimming pools of frontier AI expertise exterior of the U.S., Frederic Groussolles, associate at government search agency Heidrick & Struggles, informed CNBC.
“A decade of funding anchored by DeepMind, main analysis labs and main universities has created a mature expertise base spanning AI analysis, engineering and business management.”

Past workplace house, there are issues rising round whether or not the infrastructure wanted to assist staff and quickly growing compute calls for continues to match the tempo of progress.
“The larger problem is whether or not we proceed investing within the infrastructure that helps progress, expertise, energy, housing, transport and compute,” mentioned Ziv Reichert, associate at London-based VC agency LocalGlobe.
