The Dawn of a New Era: The US-UK Technology Prosperity Deal

In a landmark moment for global innovation, the Governments of the United States and the United Kingdom have unveiled a new Memorandum of Understanding (MOU) for the Technology Prosperity Deal. Signed on September 18, 2025, this agreement solidifies a strategic alliance to pioneer the next wave of scientific and technological breakthroughs. The deal is a testament to the shared vision of two nations committed to leveraging their deep-rooted expertise and complementary strengths to fortify freedom, enhance prosperity, and address the most pressing global challenges.

The MOU is more than a simple declaration; it is a roadmap for a Golden Age of Innovation. It builds on a history of trusted security and defence partnerships, affirming a mutual desire to produce tangible benefits for their citizens through close strategic cooperation. The agreement outlines a comprehensive plan for joint efforts in several critical and emerging fields, each designed to secure a leadership position for both nations.

Key Areas of Collaboration

The Technology Prosperity Deal sets out ambitious goals across several strategic disciplines.

Accelerating AI Innovation

Recognising AI as the defining technology of our age, the Participants intend to collaborate closely on AI infrastructure and research. The goal is to deliver transformational, AI-driven change across societies and economies. The collaboration will include establishing joint flagship research programmes between major science agencies in both countries, such as the U.S. Department of Energy and the UK Department for Science, Innovation and Technology. This will include joint funding opportunities and the allocation of compute resources to develop models and datasets in key priority areas like AI for biotechnology, precision medicine, and fusion energy.

The deal also promotes a new AI for space partnership between NASA and the UK Space Agency to develop AI models for space applications, including lunar and Martian foundational models. Furthermore, it aims to advance pro-innovation AI policy and promote the export of U.S. and UK AI technology, covering the full stack of chips, data centres, and models.

Unleashing Civil Nuclear Energy

The MOU affirms a shared belief that the world is at the dawn of a golden nuclear age. The Participants aim to lead the sector by pioneering new technologies, streamlining regulatory processes, and securing supply chains. The collaboration will focus on advanced nuclear reactors, advanced nuclear fuels, and fusion energy. Key initiatives include:

  • Accelerating Deployment: Facilitating commercial partnerships and addressing market barriers to speed up the deployment of advanced nuclear reactors in both countries.

  • Supply Chain Security: Working to ensure a reliable supply of advanced nuclear fuels and achieving full independence from Russian nuclear fuel by the end of 2028.

  • Global Leadership: Championing the safe and secure deployment of civil nuclear exports in third countries and leading the development of a harmonised, responsible policy framework for fusion energy.

Securing Quantum Advantage

As world-leading quantum nations, the U.S. and UK are joining forces to seek to be the first to realise true quantum advantage. The partnership will combine the strength of their national laboratories, the genius of their scientists, and the agility of their companies to deliver powerful quantum machines that will transform defence, finance, and healthcare. Collaborative efforts will include:

  • Benchmarking: Establishing a joint taskforce to accelerate breakthroughs in benchmarking for quantum computing hardware, software, and algorithms.

  • Algorithm Development: Launching a transatlantic Quantum Code Challenge to mobilise researchers to create new quantum algorithms for real-world use cases.

  • Industry Exchange: Creating a U.S.-UK Quantum Industry Exchange Programme to spur adoption across various sectors.

Foundations for Frontier Innovation

The agreement also lays out a number of foundational areas to support cutting-edge innovation. This includes deepening collaboration on research security to protect technologies and share best practices, particularly regarding foreign threats. The Participants also intend to enable joint research and development in 6G-relevant technologies to shape global telecommunications standards and enhance cooperation on initiatives to improve timing resilience.

To ensure these ambitious goals are met, the MOU establishes a Ministerial-Level Working Group, set to convene within six months. The group will serve as a strategic forum to guide bilateral cooperation and oversee the implementation of joint initiatives.

This Memorandum of Understanding represents a pivotal moment in the U.S.-UK partnership. By aligning their strengths and coordinating their efforts, the two nations are set to solidify their strategic leadership in science and technology, addressing global challenges and building a more prosperous future for their citizens.
