If you can believe it, today marks the halfway point of the year, and we’d be the first to tell you that it’s been a pretty wild ride in defense tech so far. As it turns out, the numbers back up our—and, if you’re reading this newsletter, your—excitement.
According to Pitchbook data provided to Tectonic, a whopping $35.6B was invested in defense and defense-adjacent startups in the first half of 2026. For those keeping score at home, that’s a 40 percent increase from 2025.
- This data, as a little disclaimer, includes space, quantum, semiconductors and microelectronics, advanced manufacturing, and energy (primarily nuclear) startups, but defense-specific companies took home a big chunk of the bacon.
We’ve said it before, and we’ll say it again: Y’all have some seriously deep pockets.
Break it down: Aside from that eye-watering topline number, there’s some interesting stuff in the data. The devil—and the dollars—are in the details.
- In Q1, defense (and defense-adjacent) startups raised $19.8B across 262 deals, “the largest single quarter the dataset has ever recorded,” per Pitchbook.
- In Q2, investors poured $15.0B into defense tech (the third-largest quarter on record, behind Q1 2026 and Q2 2025).
That’s a 27 percent drop from Q1 to Q2, but “the headline decline is misleading,” Pitchbook wrote. “The quarter closed on June 30, and small and undisclosed rounds report last, so the count…will revise upward over the coming months. [Look at the] the half instead: $35.6 billion across the first six months, already two-thirds of everything raised in all of 2025.”
- Taken together, the median round in the first half of the year still doubled year over year, jumping from $11M to $20M, so the increase is “real down the stack and not only at the top,” Pitchbook pointed out. Rising tide.
Drone dollas: There’s a whole lot of cash going to every corner of the defense tech world, but autonomy has been the year’s big winner. “Autonomy consolidated as the dominant capital allocation theme of [Q2] and the year,” per Pitchbook’s findings. “The segment now runs roughly 60% larger than the next-largest by deployed capital, at $16 billion TTM across 212 deals. All four unmanned subsegments accelerated on a trailing-year basis.”
- Within that, measuring Trailing Twelve Months (TTM), the UAV subsector grew 254 percent, UGV grew 284 percent, and USV 124 percent. Autonomous manufacturing also grew 190 percent. Picks and shovels, baby.
- Defense systems integration and optimization “led within autonomy at $5.8 billion TTM, with deal count up 91%.”
Cash cows: Looking at the year’s biggest raises, autonomy’s lead checks out. In the first half of this year, we’ve seen mega-rounds including:
- Anduril’s $5B Series H at a $61B valuation.
- Saronic’s $1.75B Series D at a $9.25B valuation.
- Shield AI’s $2B Series G at $12.7B valuation.
- STARK’s $570M funding round at a nearly $4B valuation.
- And, as of this morning, Quantum Systems’ massive $1.2B Series D at an $8B valuation. Shoutout Europe.
And it doesn’t sound like things are going to cool off on the other side of the pond any time soon—Helsing is also reportedly raising $1.2B at an $18B valuation. How do you say cha-ching in German?
Winners win: Those are some pretty big numbers, but they highlight something else.
“Capital is compounding into an existing cohort of winners rather than a fresh surge of startups,” per Pitchbook. “The dollars are concentrating, not broadening. One round, Anduril’s $5.0 billion Series H at a $61 billion valuation, accounts for 33% of the entire quarter and 14% of the half. The top five rounds account for 48%, and the top ten for 62%.”
That said, it’s not all doom and gloom for the up-and-comers. Quite the opposite.
“The market is also becoming more of a barbell. Venture growth deals rose to $9.1 billion, and early-stage value rose 47%. Later-stage value, though, fell 69%, and Series C dropped 80% quarter over quarter,” Pitchbook defense analyst Ali Javaheri told Tectonic. “To me, that says investors still want exposure to the category, but they are straddling between underwriting proven scale and taking earlier optionality.”
Looking forward to Q3, “I would expect continued momentum in weapons systems, munitions, drones/C-UAS, missile defense, and space-enabled sensing and data infrastructure, which lines up with the lessons investors are taking from the recent Iran conflict,” Javaheri added. “The conflict reinforced the importance of production depth, cheap and attritable systems, defensive capacity, and the ability to collect, process, and act on data quickly.”
Sounds like we’ll have plenty to write about over the next six months.
