The United States and the United Kingdom have signed a Technology Prosperity Deal, a wide-ranging memorandum of understanding (MOU) aimed at strengthening transatlantic cooperation in artificial intelligence, nuclear power, quantum technologies, and other frontier innovations, according to the Prime Minister’s Office.
Unveiled on September 18, the agreement commits both governments to deepen joint research, expand scientific collaboration, and align policy frameworks to secure technological leadership. Officials described the deal as a foundation for a “next Golden Age of Innovation” that will reinforce both nations’ prosperity and security.
On AI, the deal pledges to accelerate innovation by connecting U.S. and U.K. research agencies, expanding access to high-performance computing, and developing joint flagship programs in biotechnology, precision medicine, and fusion energy. It also calls for collaboration between NASA and the U.K. Space Agency on AI for space exploration, while strengthening ties between the U.S. Center for AI Standards and Innovation and the U.K. AI Security Institute.
In civil nuclear energy, both governments aim to fast-track regulatory processes, secure supply chains, and end reliance on Russian nuclear fuel by 2028. They plan to jointly promote advanced reactor technologies and fusion energy while ensuring the highest safety and non-proliferation standards.
The agreement also outlines a shared push to secure “quantum advantage,” including a U.S.-U.K. benchmarking taskforce, a transatlantic Quantum Code Challenge, and interoperable standards for quantum computing, sensing, and networking.
Beyond emerging technologies, the deal emphasizes research security, joint work on 6G telecommunications, critical infrastructure resilience, and mobilizing private capital to scale innovation.
The MOU is non-binding but establishes a ministerial-level working group to coordinate priorities within six months. Annual reviews will track progress and guide future cooperation.
