Riding the Wave: Defense ETFs to Watch After the US-UK Tech Pact

By Aparajita Dutta | September 22, 2025, 9:49 AM

The recently signed U.S.-UK Technology Prosperity Deal (“TPD”) should fuel significant growth in defense exchange-traded funds (“ETFs”), as both these nations agreed to collaborate on strengthening their respective defense bases. This landmark agreement, with a combined investment of over $350 billion from the private and public sectors, will particularly benefit defense companies that leverage artificial intelligence (AI) and data analytics.

The Rise of AI in Defense

In recent times, AI-driven defense companies have seen more traction because modern warfare is no longer just about hardware; it's also about information and speed. AI provides a critical edge by enabling militaries to process vast amounts of data from sensors, drones and satellites in real-time. This capability has become vital for making rapid, data-informed decisions on the battlefield, optimizing logistics and identifying threats with unprecedented precision.

With AI’s ability to automate tasks and enhance situational awareness, transforming military operations in modern-day warfare, defense entities are shifting their focus to AI to gain a strategic advantage over adversaries, amid the evolving global geopolitical landscape.

Deal Overview and ETF Connection

The recently signed TPD aims to propel the U.S.-U.K. special relationship into a new technological era. The deal's direct connection to defense ETFs, particularly those holding AI-driven defense-focused companies like Palantir, L3Harris Technologies, and Lockheed Martin, lies in its emphasis on strengthening the defense industrial base.

The TPD includes a commitment for the UK to purchase over $80 billion in goods from U.S. tech and defense companies over the next five years, with Palantir expected to secure a substantial contract.

By formalizing this partnership and injecting billions of dollars in investment, this strategic alignment is likely to drive revenue growth for companies with significant government defense-focused contracts. For investors, this makes defense ETFs with holdings in these companies more attractive, as the deal serves as a long-term catalyst for growth and validates the growing importance of AI in national security.
