London continues to attract global AI investment, as a new venture linked to Jeff Bezos explores expanding its presence in the UK.
The AI lab, Project Prometheus, is reportedly in talks to lease office space in the King’s Cross area, signaling sustained interest from major AI players in the region. According to reports, the company is considering a deal for 3 floors at the Jellicoe Building, covering nearly 38,000 sq ft.
The move follows Project Prometheus raising $10 billion in funding at a reported valuation of $38 billion. The company focuses on building AI systems that understand the physical world, with applications in engineering and manufacturing.
This development reflects a broader trend, with companies like OpenAI and Anthropic expanding their footprint in London as they scale operations.
According to CBRE Group, AI-led firms could occupy up to 4 million sq ft of office space in London by 2033, up from around 1.5 million sq ft today. This could account for nearly 43% of currently unleased office space under development in central London.
Industry leaders highlight the pace of growth. Michael Wiseman of British Land noted that even a small number of such expansions is positive for the city. CBRE’s Mike Gedye added that AI startups are scaling rapidly—from small co-working setups to large office footprints within 12–18 months.
Project Prometheus joins a growing list of AI firms expanding in London. Anthropic has leased 158,000 sq ft at One Triton Square, while OpenAI has secured 88,500 sq ft at Regent Quarter in King’s Cross, with capacity for up to 544 employees. Scale AI has also shifted its international headquarters to 2 Pancras Square with 11,000 sq ft, and ServiceNow is set to occupy over 50,000 sq ft at EDGE London Bridge.
Meanwhile, Great Portland Estates reports that AI-related tenants now make up nearly 12% of its office portfolio and over 25% of its flexible workspace business. The firm has also pre-leased more than 52,000 sq ft at The Delft near Borough Market to Quantexa.
Despite concerns around long-term AI demand, industry leaders note that interest in premium office space remains steady, driven by the need for high-value, well-connected locations.
