Summary: London and Washington unveiled a Tech Prosperity Deal worth about £31 billion ($42 billion), alongside a civil‑nuclear pact to accelerate small modular reactors (SMRs) and fuel supply. The tech package emphasizes AI, quantum and semiconductor collaboration, with headline pledges by major U.S. firms.
Why it matters
The twin deals link AI compute growth to energy security: data‑center demand is increasingly constrained by power. Streamlined nuclear approvals and SMR pilots could stabilize electricity costs, while deeper AI/chip ties diversify supply chains away from geopolitical chokepoints.
Key facts
- Value: roughly £31bn in private‑sector tech commitments; separate civil‑nuclear cooperation to speed SMR deployment and fuel supply.
- Scope: AI infrastructure, quantum, semiconductors; regulatory cooperation on nuclear licensing.
- Timing: announced during the U.S. president’s state visit to the UK.
What to watch
Named reactor sites and vendors; grid and planning reforms for data‑center power; concrete chip/AI investments (capacity, GPUs, locations) and any tariff side‑deals.
