Why London? The Broader Trend of North American AI Firms Investing in the Capital

Modal's expansion is part of a much larger wave of US AI companies investing heavily in London:

• OpenAI announced London as its largest research hub outside the US and opened a permanent office with capacity for over 500 staff .
• Anthropic is expanding its UK headcount from 200 to 800, with a major office in King's Cross .
• Runway (AI video generation, valued at $5.3B) chose London as its European HQ, committing over $200 million to the UK AI sector .
• CoreWeave opened a London HQ and UK data centres in 2024 .
• Luma AI (valued at $4B) has also taken London office space .

The driving factors are access to deep AI/ML engineering talent, proximity to world-class universities (Cambridge, Imperial, UCL), the UK government's pro-AI policy stance, and London's role as a gateway to the European market . The concentration is clustering around King's Cross, where DeepMind, Google, Meta, and Microsoft already have major presences .
