Britain opened four public service competitions under a £100m AI fund, but it has not said how much any winner can receive

Britain opened the first four competitions under its £100m Sovereign AI research and development procurement scheme on Monday. The subjects are NHS productivity, computing efficiency, connecting data and AI across defence systems, and security testing for AI agents.

The government did not divide the £100m among them. It also supplied no award size, number of winners or application deadline in the release.

The structure is the news.

Upfront payments will be available where appropriate, which is intended to let smaller companies build and prove technology without the turnover or cash reserves normally required for public contracts. Successful companies will retain the intellectual property they create and may develop products for other customers after the trial.

The competitions target technology beyond early research that is ready for testing in operational settings. Applications will be assessed by the Sovereign AI team, participating departments and independent technical experts against published criteria.
