Investor demand for Helsing's Series E "significantly" exceeded the stock available to sell, pushing the five-year-old German defense AI company to an $18 billion valuation, Europe's largest-ever funding round for a defense startup. Even Anduril's own CEO says the broader defense tech boom fueling deals like this one has become at least a little bit of a bubble.

On July 13, Helsing told the world what its investors already knew: everyone wanted in, and there was not enough round to go around.

The Munich-based company announced it had raised $1.8 billion in a Series E round.

The new funding values the five-year-old defense AI startup at $18 billion. Investor demand, Helsing said, "significantly" exceeded the stock available to sell. The company was not searching for money. It was turning some down.

The round instantly resets who counts as Europe's most valuable startup. Leave out the UK, home to fintech Revolut's $75 billion valuation, and no privately held company on the continent is worth more than Helsing is today.

A Year That Took Helsing From 12 Billion Euros to 18 Billion Dollars

Helsing was founded in 2021 by Gundbert Scherf, Niklas Köhler, and Torsten Reil, and it has spent five years building what it calls "software-defined" defense products: the HX-2 strike drone, the Altra AI-enabled battlefield-operations platform, and a proposed autonomous fighter jet concept called CA-1 Europa. Rheinmetall, Kongsberg, and Saab already work with Helsing to integrate its AI into their own hardware, including flying Saab's Gripen fighter with an AI system in the loop.

The company's valuation has climbed fast. Helsing raised money at a reported 12 billion euro valuation in June 2025. Thirteen months later, the Series E puts that figure at $18 billion.

The round itself grew as it came together. TechCrunch reported in mid-May that Helsing was closing in on a $1.2 billion raise at roughly that same valuation, led by Dragoneer and returning investor Lightspeed Venture Partners.

By the time the round actually closed two months later, oversubscription had pushed it to $1.8 billion at an unchanged valuation. Other participants included Disruptive, Iconiq, Goldman Sachs Alternatives, JPMorganChase, the Canada Pension Plan Investment Board, General Catalyst, Plural, and Stepstone, alongside existing investors Prima Materia, Accel, and Greenoaks.

The board stayed the same: Spotify founder Daniel Ek and former Airbus chief executive Tom Enders as co-chairmen, alongside Jeannette zu Fürstenberg and retired NATO Supreme Allied Commander Transformation Denis Mercier.

Helsing says it remains "predominantly European-owned" even after the round, a detail the company chose to highlight at a moment when European governments are pushing hard for defense-industrial independence from the United States. That push shows up elsewhere in European tech too: Mistral recently borrowed $830 million to build out its own Nvidia-powered data center in Paris, a bet on the same idea that Europe needs to own its critical AI infrastructure rather than rent it from Washington.

Europe's Defense Tech Boom Has a New Ceiling

Helsing's raise is not an isolated data point. It is the largest entry yet in a wave of European defense megadeals that has piled up in 2026 alone.

Anduril remains the category's largest company by a wide margin. It doubled its own revenue in 2025 to $2.2 billion, CEO Brian Schimpf has said.

Anduril has now raised more than $11 billion from investors since its founding in 2017, according to TechCrunch, spread across a string of rounds that only keeps accelerating.

But the gap is narrowing. Venture capital investors deployed a record $19.8 billion into defense tech globally in the first quarter of 2026 alone, according to PitchBook, more than triple the pace of early 2024. Some early-stage defense startups are now fetching 17 to 50 times revenue, multiples once reserved for consumer software.

Drones Became the Instrument of Choice, and Investors Noticed

The demand behind Helsing's round did not appear out of nowhere. Axios traced it to two forces: Europe's rapid defense spending increase amid the Russia-Ukraine war, and increasingly strained ties between European governments and the United States that have pushed the continent toward its own military AI capability. Drones, in particular, have become the defining instrument of modern warfare, and Helsing's core products sell directly into that shift.

The same forces are pulling talent and money toward companies that look nothing like a traditional defense contractor. OpenAI's Deployment Company recently bought Northslope, an applied-AI firm founded by former Palantir engineers, part of a broader race among AI labs to build the kind of embedded, mission-specific engineering teams that companies like Helsing and Palantir have spent years refining for governments and militaries specifically.

Even Anduril's CEO Calls Parts of the Market a Bubble

Not everyone chasing these valuations thinks the run can continue at this pace.

Asked directly at Fortune's Brainstorm Tech conference in June whether defense tech is in a bubble, Anduril chief executive Brian Schimpf did not deflect. "I do think there's a bit of a bubble," he said. "When there are successful companies, you have lots of other companies and investors chasing that, and there can be very risky behavior. Capital's cheap, and it's great if you can get capital as an advantage, go for it. But do understand the consequences for your company when you do: you put expectations through the roof of what you can deliver on."

Trae Stephens, an Anduril cofounder and Founders Fund partner, put the underlying mechanics more bluntly. "There's too much supply in venture capital," he said. "All of these funds are competing with one another to win deals, and the best lever they have to win deals is price. They keep chasing, chasing, and chasing." Defense contracts, he pointed out, do not scale the way consumer software does. "This isn't consumer AI. The growth curve isn't zero to $30 billion in 18 months. It's a really, really hard game."

Peter Wilczynski, a former Palantir executive now serving as chief product officer at Vantor, framed the industry's current stage bluntly: "We're probably close to the adolescent period, for sure. There are going to be teenage years in defense tech, and it's going to be awkward."

None of this criticism singles out Helsing specifically, and none of it disputes that the underlying demand for AI-enabled defense systems is real. The disagreement is about pace: whether the valuations flowing to companies like Helsing reflect defensible fundamentals or a market where, in Stephens's words, investors have stopped waiting to find out.

The Bottom Line

Strip away the multiples and the argument over bubbles, and Helsing's raise says something simpler: the largest pool of private capital chasing AI right now is not only competing over chatbots and coding assistants. A meaningful share of it is chasing autonomous drones, battlefield software, and the engineers who can build both, and investors were willing to fight over the chance to fund a five-year-old company doing it.

Whether that bet ages well depends on questions no funding round can answer: whether Helsing's products perform when governments actually deploy them at scale, and whether the "adolescent period" Wilczynski described ends in consolidation or in the kind of reckoning Schimpf himself says he is watching for. For now, the money keeps arriving faster than the answers.
