US-UK tech prosperity deal talks resume with focus on nuclear and fusion collaboration

Summary

The United States and the United Kingdom have cautiously restarted discussions on their proposed technology partnership, with early talks centered on civil nuclear cooperation and fusion energy initiatives.

LONDON/WASHINGTON, Feb. 25, 2026 — Negotiations on a proposed “tech prosperity deal” between the United States and the United Kingdom have resumed after a pause, with officials initially focusing on collaboration in advanced energy technologies, according to a Financial Times report.

The framework is intended to deepen cooperation in strategic sectors and strengthen economic ties, though discussions remain at an exploratory stage.

Energy cooperation takes priority

Early conversations are focusing on areas where both countries share strong industrial capabilities and national-security interests, including:

• Civil nuclear technology: Cooperation on next-generation reactors and supply chains.
• Fusion energy: Plans for deeper research collaboration and potential joint initiatives to accelerate commercialization.

The emphasis on energy reflects growing policy focus on energy security and low-carbon power, particularly as governments seek long-term alternatives to fossil fuels.

Background to the negotiations

The proposed partnership had stalled amid broader trade tensions, with negotiations previously complicated by differences over wider economic issues.

The current restart signals a more targeted approach, prioritizing areas of mutual strategic interest while leaving broader trade questions for separate discussions.

Officials have not provided a timeline for a final agreement, and the talks are described as preliminary.

Why this matters

Closer US-UK cooperation in nuclear and fusion technology could strengthen supply chains, accelerate innovation, and deepen strategic alignment between two major advanced economies.

For industry, progress in these areas could unlock new investment opportunities and shape the future of clean energy markets.
