This article looks at the 10 Largest Defense Stocks in 2025.

Several defense giants over the last few days raised their 2025 outlooks, citing higher demand despite tariffs and ongoing economic uncertainty. Wars in Ukraine and Gaza have spurred military spending worldwide, helping to draw investors towards defense stocks.

Another vital factor driving the momentum has been the rising defense budgets of European countries, especially after President Trump took office in January and prompted Europe to spend more on defense while stressing that Washington could no longer foot the bill.

In May, the United States agreed to sell Saudi Arabia an arms package worth $142 billion. The deal, deemed as the largest defense cooperation agreement ever made by Washington, is also contributing to the strong performance of American defense stocks.

The NYSE Arca Defense Index has surged 43.81% this year as of the close on October 23, and has comfortably outpaced the S&P 500 Index, which has returned 14.82% during the period.

While large defense stocks continue to benefit, smaller-cap contractors have also emerged as standout performers this year, amid surging demand for next-generation, low-cost military technology as nations modernize their militaries with AI-powered drones and unmanned vehicles that are cheap and cut dependence on ground forces.

Jon Siegmann, Managing Director at Stifel, who covers the aerospace and defense industry, was quoted as saying the following by Reuters last month about the shift towards agile and adaptable combat systems:

“The winners in this new market will be those companies leaning into the change and investing in low-cost, upgradable, and software-enabled weapon systems.”

With that said, let’s now head over to see the 10 Largest Defense Stocks in 2025.
