Shares of major defence companies surged in global markets as escalating tensions between the United States and Iran drove expectations of higher military spending and increased demand for weapons systems and defence technology.
Investors turned to defence contractors after reports of military strikes and widening conflict in the Middle East. Companies such as Lockheed Martin, Palantir Technologies, RTX Corporation, Northrop Grumman, and L3Harris Technologies recorded gains as traders bet the conflict would boost defence budgets and procurement.
Among the standout performers was Palantir, whose shares climbed about 6% as investors focused on the company’s role in military intelligence and battlefield data analytics used by governments and defence agencies. Analysts say technology firms involved in surveillance, AI-driven analytics and battlefield software are increasingly viewed as key players in modern warfare.

Traditional weapons manufacturers also moved higher. Lockheed Martin — the largest U.S. defence contractor and maker of the F-35 fighter jet — along with RTX and Northrop Grumman saw stock gains as markets anticipated increased demand for missiles, air-defence systems and aircraft if the conflict continues.
The broader defence sector benefited from the geopolitical shock. Analysts note that military conflicts typically push governments to replenish weapons stockpiles and accelerate procurement, which can boost revenues for major arms producers. Over the past few years, companies such as RTX, Northrop Grumman and Lockheed Martin have already seen substantial stock gains amid rising global defence spending.
However, market reactions have not been uniform. While some defence stocks rallied on expectations of higher military demand, others fluctuated due to uncertainty about how long the conflict might last and how governments will respond economically. Despite short-term volatility, analysts say geopolitical tensions continue to keep defence and military technology companies in strong focus among investors.
