UK Government Launches $675 Million Sovereign AI Fund

Apr 17, 2026

The UK government launches a $675 million Sovereign AI venture fund led by James Wise and Joséphine Kant to invest in domestic AI startups across model development, agentic AI, and drug discovery, aiming to reduce dependence on foreign technology dominated by US and Asian rivals. The fund offers portfolio companies access to UK supercomputers, free visas for international hires, and government procurement opportunities, with initial investments including Callosum and compute grants to six startups like Prima Mente and Cosine. While the UK hosts prominent AI companies like Google DeepMind and ARM, experts note the fund's size is small compared to hundreds of billions spent by major AI companies, and complete self-sufficiency in general-purpose AI development remains highly unlikely. The initiative represents part of Britain's broader January 2025 plan to position itself as an 'AI maker' and capture a larger share of global AI investment while minimizing trade negotiation vulnerabilities.
