State of Small-Cap Defense Investing 2026: A Prime Reckoning

For most of the past two decades, the defense trade was a one-liner. You owned the primes: Lockheed Martin, RTX, Northrop Grumman, General Dynamics, Boeing.

Those names, and a handful of others, were the institutional stalwarts holding backlog and the moat.

Meanwhile, the Feds related to them the way they always had, as patient customers writing cost-plus checks for exquisite hardware on decade-long timelines.

Two things are upending that arrangement at once.

First, the character of warfare is shifting toward cheap, autonomous, attritable mass, the kind of fight the prime model was never built to supply at tempo.

Think SR-71 Blackbird vs waves of DJI-style quadcopters. The machinery built to produce the first is structurally ill-suited to turning out the second at scale, and the reason is as much economic as industrial. A company organized around low-volume, high-margin exquisite hardware doesn't pivot to high-volume disposable mass without breaking the model that makes it money.

At the same time, Washington's posture toward the primes is hardening, from patronage to something more demanding.

Put those together, and long-term investment value starts migrating away from the integrators at the top of the stack.

This year’s Iran conflict made the first half of that vivid. Somewhere over the Persian Gulf this spring, a Patriot interceptor worth roughly $4 million left its launcher to kill an Iranian drone that cost about as much as a used truck.

Then it happened again.

And again.

By the time of this writing (June 2026), the United States had fired close to half its prewar inventory of Patriot interceptors and nearly a thousand Tomahawks, dwarfing prior-year strategic munition burn rates.

In other words, America’s strategic arsenal met cheap mass, and the magazine ran dry in just weeks. Full replenishment is now ballparked to somewhere between 2029 and 2031.

But Iran is just the most dramatic example, with the same dynamic playing out wherever you look (Ukraine, our southern border, Africa, plenty other flash points) and the lesson Iran taught about the top of the arsenal is the same lesson the rest of the world is teaching about the bottom of it.

Wartime economics have inverted, and the side fielding ten-thousand-dollar systems increasingly sets the terms for the side fielding ten-million-dollar ones.

The second half of the sea change has been building since the administration took office, and it does not depend on any single war, current or future forecasted. Washington has started buying equity in the companies it considers strategic, taking stakes in Intel, rare-earth miners, and potentially even in small-cap drone stocks (hit the link below for more on that emerging development).

Uncle Sam is also standing up fast-acquisition shops, like the Joint Interagency Task Force 401. JIATF 401 and other, similarly-structured Federal collectives have a mandate to reach past primes and field low-cost systems in months. And the Pentagon has stated, in directive after directive, increased appetite for commercial technology and new entrants to supplant incumbents who spent decades learning to win the old way.

The pressure ends up running in three directions:

To see why the primes are exposed, you have to see how they get paid. The traditional model runs on cost-plus contracting, with the government reimbursing a contractor's costs and slapping a fee on top, since there's no commercial margin to earn.  

For something genuinely exquisite, i.e., a nuclear submarine or a high-altitude interceptor, that has a logic to it. The work is hard and risky, with zero commercial market for true price discovery.

The trouble is what the model rewards.

When your fee scales with your costs, controlling those costs works against you. Stack on a requirements process that specifies bespoke systems years before they're built and vendor lock that ties the government to one supplier for the life of a program, and what do you get? An industry optimized for high-cost, low-volume, long-horizon work where winners take all and hold a near-monopoly on a project for decades no matter how well (or poorly) it progresses.  

Pete Hegseth has described his own department's system as one of "limited competition, vendor lock, cost-plus contracts," and his acquisition overhaul pushes toward fixed-price deals at commercial speed. The overall turn in acquisition mindset has been years in the making, so this is a long arc, not a sudden break.

What recent conflicts did was make a slow bureaucratic argument urgent, because the model that struggles most against cheap mass at wartime tempo is exactly the one the primes were built around.

For most of the postwar period, defense and commercial technology ran on separate tracks with separate supply chains, but that’s increasingly broken down. Several recent decisive capabilities came from companies building for civilian markets first; the government is now wiring that dependence into doctrine.

The clearest case is space, where commercial satellite communications held up in contested airspace where purpose-built military links have struggled and commercial imagery firms (Planet Labs, notably) became part of the story as it unfolded. Underscoring the move toward high-end commercial/defense utility, the Space Force has begun formalizing its reliance on private capacity rather than trying to replace it.

Here is the inversion, and it is the whole point:

With a traditional defense pure-play, the question is whether the Pentagon will fund the company.With a dual-use company, the question is whether the Pentagon can afford to pass on something the commercial market has already validated, priced, and scaled. Likewise, the dual-use firm carries independent revenue and pricing power the primes never had, because it does not need the contract to survive.

One distinction matters, however.

Dual-use runs in two directions, and only one of them is attractive. A commercial company being pulled into defense brings pricing power and a revenue base that does not depend on Washington. A defense contractor chasing commercial markets to escape margin compression is a different and riskier animal, often without proven product-market fit.

The FY26 NDAA raised the threshold for certified cost and pricing data from $2M to $10M, directed regulators to strip out barriers that fall hardest on small and non-traditional contractors, and exempted those firms from accounting requirements that have long functioned as a moat.

The FY27 request goes further, naming drone dominance a presidential priority inside a topline approaching $1.5T.

The investor implication is clean, as fixed-price contracting transfers risk from the government to the contractor and caps the upside cost-plus previously guaranteed.

At the same time, the reforms lower the barriers that kept smaller and newer firms out of the room.

In other words, newfound margin pressure on the incumbents and an open door for the challengers, written into the same set of rules.

Institutional capital is taking notice. Booz Allen tripled an internal venture fund to $300 million, and Andreessen Horowitz built an “American Dynamism” practice aimed squarely at this opening.

When the incumbents start standing up venture arms to buy their way into the new model, it’s easy to tell which way the winds are blowing.

Then there is the development with no recent precedent. The federal government has stopped behaving only as a customer and a grant-writer and started taking equity.

The template was set in semiconductors, where a government stake in Intel preceded a roughly 491% move in the stock over the past year. Similar stakes followed across rare earths and quantum computing. And, late last month, the Pentagon was reported to be in talks to take equity or debt positions in domestic drone makers; shares of Unusual Machines jumped more than 65% on the news and continued climbing.

When Washington takes a stake, it is naming the companies and sectors it intends to energize and scale. That signal is landing disproportionately on small and mid-cap names in strategic niches, not on the primes, which do not need the capital.

Put the three pressures together and you can see where value is migrating, i.e., away from the prime integrator at the top of the stack, and toward the layers beneath and beside it.

Why small caps capture this better than the primes is arithmetic. A new $264 million backlog addition is a rounding error for a $50 billion prime but a game-changing transformation for a $300 million company.

Position sizes that are immaterial to institutional defense budgets are decisive at the bottom of the market.

That is one of this newsletter’s core small-cap theses, now sitting on top of a structural shift in warfare and a government writing checks into exactly these niches.

A thesis this clean deserves a hard look at what breaks it.

Start with the most uncomfortable evidence. The cleanest test of whether Washington would actually squeeze the primes was the fight over right-to-repair, the push to force contractors to hand over the technical data the military needs to fix its own equipment. It had the White House, the House, the Senate, and senior Pentagon leadership behind it.

It lost. Industry lobbying stripped the provision from the final 2026 NDAA.

A renewed version is back for the 2027 bill, but the lesson holds: policy intent and policy outcome are different things, and the incumbents are very good at the distance between them.

Second, urgency fades. The argument runs partly on wartime tempo, and tempo cools. If the crises that exposed these gaps recede, the demand for more, faster, and cheaper can soften, budgets can drift back toward normal, and the cost-plus machine can reassert itself. Defense reform has a long record of dying quietly in peacetime.

Third, government equity cuts both ways. The same stake that signals survival introduces political risk, conflict-of-interest exposure, and the chance that capital gets allocated for reasons that have nothing to do with running a good business.

State-picked winners are not always sound companies, and an entry point after a post-Pentagon stake announcement is not the same deal early holders got.

For the small-cap investor, this may be the richest setup defense has offered in a generation, with the usual condition attached (you have to stomach the volatility and have the discernment to tell the real businesses from the press releases).

In part two, we’ll work through the gaps this shift has opened, where they came from, and the small-cap companies positioned across multiple domains:
