GoKawiilHundreds of billions of dollars have poured into defense tech over the past several years. As a result, new defense-tech companies are launching every day. Whenever that much capital chases a single sector, you create the conditions for a bubble.
And as many have commented, that’s exactly what’s happening right now.
You have defense-tech startups raising Series A rounds at $300 million or $400 million valuations with no recurring revenue, no meaningful long-term contracts, and, in many cases, little more than a vision. Case in point, last month Reuters reported that four former DOGE staffers had raised $160M at a $1.4B valuation for a pre-product company. The plan? Maybe to acquire a data center that could be used for AI cyber operations.
Those valuations are built on speculation about what we all hope the market could become rather than what it is. The problem is that the defense market itself isn’t nearly as large as people assume. Yes, the U.S. defense budget is enormous. But that headline number is doing a lot of work in pitch decks right now.
The Real Market Size for Defense-Tech
The Trump Administration’s 2027 budget request is $1.5 trillion. But that is not the defense-tech market. The actual funding lines to buy new technology come only from procurement and RDT&E dollars, which the FY27 request puts at roughly $760 billion combined (and more than a third of that depends on a $280 billion reconciliation package Congress hasn’t passed yet). The durable base is closer to $480 billion. Everything else, including pay and benefits, operations and maintenance, healthcare, facilities, is off the table.
Within the $480 billion, most modernization dollars are already spoken for. Shipbuilding, munitions, aircraft, and nuclear modernization flow through programs of record that are sole-sourced or effectively closed to new entrants. The five legacy primes still capture the vast majority of these obligations.
So for the genuinely contestable slice of the pie (i.e., autonomy, drones, software, sensing, space), the FY27 request carves out roughly $54 billion for autonomous systems and $39 billion for drone procurement. That is real money. But those are requests, not appropriations, and even appropriated dollars will likely flow mostly to established players.
If we look backwards, we can see how this plays out.
In FY25, federal obligations to all VC and PE-backed national-security companies totaled $4.3 billion. At the same time, nearly $50 billion of venture capital invested in the sector last year. More than ten dollars went in for every dollar of government revenue that came out.
