Modern warfare is evolving quickly alongside emerging technologies, unlocking unprecedented investment opportunities in diverse areas of the defense sector.
Escalating conflicts in Europe and the Middle East are prompting governments worldwide to increase military spending. Looking at the US alone, the passage of the One Big Beautiful Bill Act has the potential to bring a US$150 billion investment into the defense industry. In addition, the Trump administration is proposing a US$1 trillion defense budget for 2026 with a focus on cybersecurity, artificial intelligence (AI) and autonomous systems capabilities.
The biggest US defense contractors and exchange-traded funds (ETFs) are expected to benefit greatly from the huge government spending expected in the sector. As for up-and-coming American defense companies that offer investors growth opportunities, those that can quickly develop and commercialize dual-capability technologies (i.e. for both civil sector and defense markets) are looking equally as attractive.
“If the opportunity is purely in the defense sector, that’s a big, but ultimately limited, opportunity. If the opportunity is in defense and a range of other sectors because the technology has got a transversal application, then it becomes far more interesting for an investor,” notes Joe Cassidy, partner, technology, media and telecom at KPMG in the UK.
Here the Investing News Network (INN) looks at the key trends shaping today’s defense and security investing sector, as well as publicly traded defense stocks with dual-capability technologies.
Defense and security trends: Nature of war is changing
Defense spending jumped nearly 10 percent in 2024, according to a KPMG report on emerging trends in the aerospace and defense sector, representing “its fastest growth rate in nearly four decades.”
The firm attributes this growth to geopolitical destabilization both in Europe and in the Middle East. The global trade war surrounding rare earths, platinum-group metals, aluminum, steel and semiconductors is adding further pressure.
This increase in domestic defense spending has been translating into big wins for defense and security stocks. As Raymond James’ September Defense & Government Market Intel Report shows, publicly traded companies in the US defense sector are up by 57.8 percent since September 2024.
In a June interview with Federal News Network’s Terry Gerton, Sam Maness, managing director of Raymond James’ Defense and Government Group, ascribed the growth to the anticipated increase in funding for domestic defense contractors. He noted that US-China tensions and other geopolitical conflicts are “lead(ing) to bullishness for anything that is more meaningfully touching mission, and defense technology naturally does that.”
Looking forward, analysts expect supply chain sovereignty and cutting-edge technological advancements to be the major themes in this sector as nations look to cost-effectively build out their domestic defense industries. At the same time, new weapons systems are reshaping the nature of war both on the battlefield and online.
“The way conflicts are resolved is changing rapidly and new technologies are disrupting the battlefield strategy,” states KPMG in its report. “Defense departments need rapid innovation and are no longer willing to wait years for a custom system when an ‘80% Solution’ can be purchased off-the-shelf.”
So what technologies are getting the most attention in the defense sector?
As mentioned, cybersecurity, autonomous systems and AI solutions are in the spotlight, and companies with dual-capability technologies are getting recognition. Below are examples of defense stocks tracked by Raymond James that are focused on providing these technologies to both the civil and defense sectors.
Cybersecurity defense stocks
One of the greatest threats to modern militaries is cyber attacks. This makes securing military IT infrastructure, communications networks and weapons systems mission critical for today’s armed forces.
