NATO chief Mark Rutte has a name for it: the “Trump Trillion.” That's the more than $1.21 trillion in additional defense spending by NATO allies since President Donald Trump's first term. For investors, it's not just a political soundbite—it's a multi-year demand pipeline for the biggest U.S. defense contractors.

We're talking about companies like Lockheed Martin Corp (LMT), RTX Corp (RTX), The Boeing Co (BA) and Northrop Grumman Corp (NOC). And the numbers are staggering.

The ‘Trump Trillion’ Behind Defense Stocks

According to a White House fact sheet released after the NATO Summit in Ankara, allied nations have committed an additional $1.21 trillion to defense spending since Trump's first term. That includes more than $120 billion in new spending just last year. The administration also highlighted that NATO allies purchased more than $54 billion in U.S. defense equipment in 2025, supporting American manufacturers and shifting more of the alliance's defense burden to Europe.

The White House says these commitments build on NATO members' pledge to increase defense spending to 5% of GDP by 2035—a target Trump has repeatedly championed.

Lockheed, RTX, Boeing and Northrop Are Already Seeing the Benefits

The summit wasn't just about spending targets. It also produced a series of new defense partnerships involving some of America's largest contractors. Here's what was announced:

• Lockheed Martin will help establish a Patriot Advanced Capability-3 (PAC-3) missile sustainment facility in Europe and partner with Germany's Rheinmetall to expand Army Tactical Missile System (ATACMS) production.
• Northrop Grumman signed letters of interest with 10 nations for its MQ-4C Triton surveillance aircraft, expanding NATO's Allied Ground Surveillance program into the maritime domain.
• RTX will launch an Advanced Medium-Range Air-to-Air Missile (AMRAAM) feasibility study to expand production in Europe, while Germany and the Netherlands plan to procure Raytheon's Stinger missiles, with European production expected to double by 2030.
• Boeing and Rheinmetall Italia announced plans to explore expanding production and sustainment of Boeing's Small Diameter Bomb for European customers.

The Investment Case

The White House also announced roughly $3 billion in new defense-related deals and joint ventures unveiled during the summit. The administration says these initiatives will strengthen the U.S. defense industrial base while opening additional export opportunities for American companies.

While many of the agreements focus on expanding manufacturing capacity in Europe, they also reinforce demand for U.S.-designed defense systems at a time when NATO members are committing to significantly higher military spending.

For investors, that could mean the story extends well beyond a single summit. If NATO members follow through on their long-term spending commitments, companies like Lockheed Martin, RTX, Boeing and Northrop Grumman could remain at the center of one of the largest defense procurement cycles in decades.
