Defense tech startups race to public markets as Pentagon spending surges
Money Moves
AEVEX joins a wave of defense technology companies—including Arxis and Swarmer—tapping public investors amid record military budgets and battlefield-proven drone technology
AEVEX Aerospace, a maker of military drones and airborne surveillance systems, began trading on the New York Stock Exchange on April 17, 2026, under the ticker AVEX—and its first day answered a central question about the defense tech IPO wave. Shares opened at $23.01 and closed at $26.93, a 34.7% gain that pushed its market capitalization to roughly $3 billion, well above the $2.35 billion valuation at pricing.
The company had raised $320 million by pricing 16 million shares at $20 each, and the offering was multiple times oversubscribed, with private equity firm Madison Dearborn Partners retaining 79% voting control. On its second trading day, April 20, AEVEX shares rose another 24% to close at $33.41. AEVEX was not the only defense company testing public market appetite that week or in the months prior: satellite maker York Space Systems raised $629 million in a January 2026 NYSE debut, components maker Arxis raised $1.13 billion on April 16 and held its gains near $38 in subsequent trading, Ukrainian drone software company Swarmer jumped more than 500% on its March 17 Nasdaq listing, and signals intelligence firm HawkEye 360 had filed its own IPO prospectus days before AEVEX's debut.
The timing reflects a structural shift in how defense technology is funded. Defense tech venture capital deals hit $49.1 billion in 2025, nearly doubling the prior year. The Pentagon's proposed fiscal year 2027 budget of $1.5 trillion would be a 44% increase, the largest jump since the Korean War. Europe is rearming at a pace not seen in decades, and the Ukraine conflict has made autonomous drones a proven battlefield technology rather than a speculative bet. Anduril Industries, the sector's most anticipated potential listing, won a U.S. Army contract worth up to $20 billion in March 2026, closed a $5 billion private round at a $61 billion valuation in May 2026, and the Air Force flew its autonomous YFQ-44A Fury fighter in experimental operations at Edwards Air Force Base April 5-12; secondary market trading now implies a valuation above $60 billion. For investors who once avoided defense on ethical grounds, those objections have largely evaporated: the number of venture firms actively investing in defense tech rose 41% in 2025.
Why it matters
Record military budgets and battlefield-proven drone technology are creating the largest defense investment wave since the Cold War ended.

Scenarios
1
Defense tech IPO wave peaks with Anduril listing, sector becomes permanent Wall Street fixture
Likely
Discussed by: Bessemer Venture Partners, Renaissance Capital, defense industry analysts
Anduril goes public in late 2026 or 2027 at a valuation above $50 billion, validating the entire sector. Shield AI, Skydio, and a half-dozen other companies follow within 18 months. Defense tech earns its own sector classification alongside traditional primes like Lockheed Martin and Raytheon. Sustained Pentagon budgets above $1 trillion and European rearmament provide durable revenue bases. The sector draws institutional investors who previously only held legacy defense stocks.
The proposed $1.5 trillion defense budget faces steep resistance in Congress, where deficit concerns force significant cuts. Sequestration-like spending caps return. Defense tech companies that priced their IPOs on the assumption of ever-growing military budgets see revenues plateau. Some newly public companies trade below their offering prices within a year, cooling investor enthusiasm and delaying later IPOs like Anduril's.
Discussed by: S&P Global Market Intelligence, defense M&A analysts
Rather than competing with nimble startups on autonomy and software, established contractors like Lockheed Martin, RTX (formerly Raytheon), and Northrop Grumman go on an acquisition spree—much as the post-Cold War wave of mergers created today's defense giants. Several companies that filed for IPOs accept acquisition offers instead. The defense tech startup ecosystem gets absorbed into the existing industrial base rather than creating a lasting parallel to it.
Discussed by: European Council on Foreign Relations, peace and conflict researchers
A ceasefire in Ukraine, stabilization in the Taiwan Strait, or a shift in U.S. foreign policy toward retrenchment removes the urgency driving defense spending. European rearmament slows as the immediate threat perception fades. Defense tech valuations, built on assumptions of sustained conflict and rising budgets, compress sharply. Companies with diversified commercial applications survive; pure-play military drone makers struggle.
Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
September 2001 – 2008
Post-9/11 defense industry surge (2001–2008)
Defense contractor stocks surged on the first trading day after the September 11 attacks. Over the following seven years, U.S. military spending exceeded Cold War peaks as the wars in Afghanistan and Iraq drove annual budget increases above 10%. Companies like Northrop Grumman, General Dynamics, and L-3 Technologies saw revenues and stock prices multiply.
Then
Defense stocks outperformed the market for nearly a decade. New entrants focused on counterterrorism, surveillance, and force protection became acquisition targets.
Now
The boom ended with budget sequestration in 2013, which imposed automatic spending caps and forced painful cuts. Companies that had built their business models around ever-growing budgets were hit hardest.
Why this matters now
Today's defense tech wave shares the post-9/11 pattern of a geopolitical shock (Ukraine, China tensions) driving rapid spending increases. The sequestration aftermath is a cautionary parallel for companies pricing IPOs on the assumption that proposed budget increases will materialize.
2 of 3
1993 – 1997
Post-Cold War defense consolidation (1993–1997)
After the Soviet Union collapsed, the Pentagon's budget shrank 35% in real terms. Defense Secretary Les Aspin hosted a dinner in 1993—later called the "Last Supper"—where he told executives that half of them would not survive as independent companies. Within four years, Lockheed merged with Martin Marietta, Northrop acquired Grumman, Boeing absorbed McDonnell Douglas, and Raytheon bought Hughes Electronics.
Then
The number of major defense prime contractors shrank from over a dozen to five. Tens of thousands of defense workers lost their jobs as duplicative operations were eliminated.
Now
The consolidated primes became enormously powerful but also slow-moving, creating the very gap that today's startups are trying to exploit. The Pentagon's current frustration with the pace of innovation from legacy primes is a direct consequence of the consolidation it encouraged 30 years ago.
Why this matters now
If budget growth stalls or reverses, the current crop of defense tech startups may face a similar wave of consolidation—acquired by the same legacy primes they are trying to displace. The "Last Supper" pattern suggests that defense market contractions favor large incumbents over small innovators.

September 2020
Palantir Technologies IPO (2020)
Palantir, a data analytics company with deep government and intelligence community ties, went public via direct listing on the NYSE at a $22 billion valuation. Founded in 2003 with Central Intelligence Agency backing through In-Q-Tel, Palantir had spent 17 years as a private company before listing. Its government revenue was approximately 56% of total sales at the time of listing.
Then
The stock nearly tripled in its first three months as retail and institutional investors piled in. Palantir became the proof-of-concept that defense and intelligence-focused tech companies could thrive in public markets.
Now
Palantir's market capitalization grew to over $250 billion by early 2025, making it one of the most valuable defense-adjacent companies in the world. Its success opened the door for the current wave of defense tech IPOs by demonstrating that public investors would pay premium valuations for government-focused technology.
Why this matters now
Palantir is the direct ancestor of the current defense tech IPO boom. AEVEX and its peers are following the trail Palantir blazed, though they face a key test: whether companies with hardware-heavy business models (drones, satellites) can command the same multiples as Palantir's software-driven margins.
