The Defense Spending Boom — and How to Invest in It

Published March 2026  |  Reading time: ~6 min

The Most Boring-Sounding Exciting Trade of 2026

Defense. It doesn't have the dopamine hit of AI, the cult following of crypto, or the dinner-party appeal of real estate. It's F-35s and missile systems and congressional budget hearings. Nobody puts "long Lockheed Martin" on a t-shirt.

And yet, defense stocks in 2026 are outperforming almost everything. LMT hit an all-time high of $692 in early March. RTX's backlog swelled to a record $268 billion. NOC surged 6% in a single session after its B-21 Raider made its operational combat debut. The ITA aerospace and defense ETF has returned nearly 49% over the past year alone.

This isn't a momentum trade. It's a structural, multi-year spending cycle backed by government checkbooks from Washington to Warsaw. Let's break down what's driving it — and how to get positioned.

What's Driving the Defense Spending Boom

NATO Rearmament

For decades, NATO members free-rode on U.S. defense guarantees while spending as little as 1–2% of GDP on their own militaries. That era is over. In 2014, only three NATO allies met the 2% GDP target. By 2025, all 32 NATO member states hit or exceeded 2% for the first time. Then, at the 2025 NATO Summit, allies committed to spending 5% of GDP on defense by 2035. Total NATO spending at full compliance could hit $4.2 trillion per year.

Poland is already at 4.7% of GDP. The Baltic states, Denmark, and Norway all exceeded 3%. Europe isn't just talking — they're writing checks.

The US Defense Budget

The US spent $919 billion on national defense in FY 2025. Congress added an additional $150 billion through supplemental appropriations. The president has floated a $1.5 trillion FY 2027 budget request. Even if trimmed, the directional trend is unmistakable.

Geopolitical Tension

Ongoing conflict in the Middle East, a hot war in Europe's neighborhood, and rising pressure in the Taiwan Strait have shifted the Western consensus. Defense spending is no longer politically controversial — it's a bipartisan imperative. Global defense spending is projected to top $2.6 trillion in 2026, an 8.1% increase over 2025.

How to Invest in Defense Stocks in 2026

ITA — iShares U.S. Aerospace & Defense ETF

The straightforward entry point. 44 companies, 0.38% expense ratio, ~49% return over the past year. If you believe in the macro thesis but don't want single-stock risk, ITA is the cleanest expression.

LMT — Lockheed Martin

World's largest defense contractor. F-35, THAAD, hypersonics. $194 billion backlog. Every major escalation event sends LMT higher. Most geopolitically sensitive name in the space.

RTX — RTX Corporation

The missile and precision weapons play. Tomahawk cruise missiles, AMRAAM air-to-air missiles — among the most in-demand items in Western arsenals. Record $268 billion backlog. Pays a dividend. Forward P/E ~20x.

NOC — Northrop Grumman

Stealth and strategic deterrence. B-21 Raider just made its operational combat debut. Heavy involvement in space and cybersecurity. Limited competition in its key programs. Forward P/E ~26x.

Risk Factors — What Could Go Wrong

• Valuation stretch. LMT, RTX, and NOC are trading at premiums to historical P/E ranges. Earnings disappointment could compress multiples fast.
• Budget uncertainty. Washington can still produce continuing resolutions or DoD efficiency drives that delay contract awards.
• Execution risk. Fixed-price contracts mean cost overruns punish earnings even in a strong spending environment.
• Geopolitical de-escalation. A negotiated peace could create a sell-the-news moment, even if it doesn't reverse the structural trend.

This Is a Cycle, Not a Trade

The comparison worth understanding is post-Cold War demilitarization in reverse. From the 1990s through 2014, NATO countries systematically drew down defense budgets. That 25-year drawdown is now being unwound — not over months, but over a decade or more.

The contracts being awarded today fund programs that run through the 2030s. If you're a W-2 earner building a rules-based portfolio around macro themes, defense belongs in it. Not because of a single news cycle, but because the capital allocation decision has already been made at the government level. You're just getting in line behind it.
