UK Department for Science, Innovation and Technology launches a £500 million sovereign AI fund. Builds on Britain's AI heritage — from Ada Lovelace to AlphaFold — targeting the UK's £1 trillion tech market, 200+ unicorns, and 5,800+ AI companies. Part of a broader £18 billion programme into UK sovereign AI infrastructure over five years, including the £150M AI Pathfinder GPU deployment in Northamptonshire. The UK claims the largest AI sector in Europe.
Technology Secretary Liz Kendall formally launched the £500M Sovereign AI Unit at Wayve's King's Cross HQ. First equity investment in AI infrastructure startup Callosum (Cambridge-founded, chip orchestration). Six additional startups — Prima Mente, Cosine, Cursive, Doubleword, Twig Bio, Odyssey — received up to 1M GPU-hours each on the national AI Research Resource. An £80M procurement engagement opened for prototype projects (up to £5M each, 12-24 month contracts, competitive rounds from July 2026). A £160M Strategic Assets Programme planned for later 2026 subject to Treasury approval.
Two frontier AI startups founded by UCL researchers raised a combined $1.6B in early-stage financing — Europe's largest-ever AI funding rounds. Ineffable Intelligence, founded by David Silver (former Google DeepMind), raised $1.1B in seed funding. This came days after the Sovereign AI Fund's first cohort of 7 companies was announced.

Second of two application windows closed 14:00 BST June 5.

Open to AI startups, research orgs, universities, consortia. Rolling EOIs continue.
Following the June 12 Anthropic disable, UK politicians across party lines framed the event as a "wake-up call" for UK AI sovereignty. Defence Minister Al Carns: British hospitals, companies, researchers were using Fable 5 before the abrupt shutdown. Former Security Minister Tom Tugendhat: sovereignty is now more about "code than cannons"; UK's policy response of "build the brake" is inadequate. UK Government formally re-elevated Sovereign AI Fund as stated policy priority. Starmer June 13-15 White House carveout lobby unsuccessful. CityAM + Telegraph used "kill switch" framing in mainstream finance coverage.
