What is the size of the defense tech market in 2026?
What results can we find on the internet?
As you probably know already, many firms regularly publish (sometimes conflicting) estimates of the defense tech market size, using different definitions, scopes, and years.
We have consolidated their results here. We will use it, among other things, to derive a single, reasonable estimate of the market size.
| Research Company | Market Size (USD) | Year | Market Definition & Fit |

What if we try to make our own estimate?
We don't have to rely only on external analyses to estimate market size.
We will try to build a first-principles, bottom-up calculation, then run a few sanity checks to see whether we can reliably estimate the size of the defense tech market.
Useful data about the defense tech market
Here is some useful and reliable data we have collected, they will help us estimate the size of the defense tech market:
- World military expenditure reached $2,718 billion in 2024, a record high (SIPRI)
- United States military spending totaled $997 billion in 2024 according to SIPRI data (Reuters)

Method and calculation to get the size of the defense tech market
Countries around the world spent $2,718 billion on their military forces in 2024. This number is too broad for our purposes because it includes salaries, pensions, and many operational costs that are not technology purchases.
A better starting point is what suppliers actually sell to defense buyers. The Top 100 arms and military services companies earned $679 billion in revenues during 2024, which represents technology products and mission systems sold into defense demand.
However, this Top 100 figure is incomplete. It misses suppliers outside the Top 100 ranking, including many smaller mission software firms, cyber vendors, and regional defense contractors.
It also under-counts parts of national-security procurement that do not show up as traditional arms company revenue. Intelligence agencies buy significant technology, as shown by the US National Intelligence Program budget of $73.4 billion and Military Intelligence Program budget of $29.8 billion.
We can build upward from the $679 billion base by adding 10 to 20 percent for non-Top-100 suppliers and intelligence-focused technology procurement. This calculation yields approximately $750 billion to $820 billion as a 2026-sized market.
We choose $750 billion as a conservative baseline that captures defense tech sold globally while avoiding the inflation that comes from including all military spending.
Sanity checks
Let's verify this estimate makes sense (we always double-check everything, as you will see in our pitch deck covering the defense tech market).
Our $750 billion estimate represents approximately 28 percent of the $2,718 billion in total world military expenditure. This proportion feels plausible since personnel costs and operational expenses consume the majority of military budgets.
We can also check against major technology categories within defense tech. C4ISR systems alone total about $131.5 billion, defense electronics reach $176 billion, military communications equal $34.7 billion, and defense cyber sits at $30.5 billion. These four categories already sum to roughly $373 billion before adding autonomy, space security, weapons systems, and vehicles.
Finally, the Top 100 arms suppliers generated $679 billion in 2024 revenues. Our full market estimate of $750 billion is only modestly higher, which aligns with the Top 100 capturing a large share of total defense tech sales.
What's our final guess then?
The defense tech market is worth approximately $750 billion in 2026, based on technology products and mission systems sold to defense and intelligence buyers worldwide.
This market size is comparable to the global pharmaceutical market, which reaches about $700 billion, and slightly larger than the global semiconductor industry at roughly $600 billion. These comparisons help confirm our estimate sits in a reasonable range.
The defense tech market in 2026 excludes general government IT services and commercial aerospace manufacturing while including autonomy, mission software, ISR sensors, communications, cyber, space security, and other defense-focused technologies.
Major technology segments drive this $750 billion total. Defense electronics contribute around $176 billion, C4ISR systems add approximately $131.5 billion, and cyber, communications, autonomy, and space security combine for several hundred billion more.
This estimate also aligns with supplier revenue data, where the Top 100 arms companies earned $679 billion in 2024 and thousands of smaller defense tech providers add incremental revenue to reach our $750 billion global market size.

What would it take for the defense tech market to be worth $1.9 trillion?
Sustained defense spending expansion globally would need to continue for multiple years, driven by geopolitical tensions rather than short-term spikes. Countries would need to maintain rearmament programs through 2036 without reverting to lower spending levels when immediate threats subside.
The defense tech market would need to capture a higher share of military budgets through increased software and cyber spending. Militaries would need to shift from hardware-heavy procurement toward software-defined defense architectures with continuous upgrade cycles.
Industrial capacity expansion would need to succeed across the defense tech ecosystem. More suppliers would need to enter the market, production cycles would need to accelerate, and current bottlenecks in components and subsystems would need resolution.
Autonomy and uncrewed systems would need to scale dramatically beyond current deployment levels. Militaries would need to field thousands of autonomous platforms across air, ground, maritime, and space domains rather than limited pilot programs.
Space security technologies would need to become a much larger budget priority as military operations become more dependent on space-based capabilities. Countries would need to invest heavily in resilient space architectures and protection against anti-satellite threats.
Mission software revenue models would need to shift toward continuous subscriptions and upgrades instead of traditional one-time purchases. Defense organizations would need to adopt commercial software update cadences rather than decade-long modernization cycles.
Intelligence agencies would need to increase technology procurement substantially beyond current levels. The defense tech market reaching $1.9 trillion by 2036 would require intelligence buyers to expand their already significant $73.4 billion annual technology budgets.
Cyber capabilities would need to maintain their 11 percent growth rate through 2036 while expanding into new domains. The defense tech market would need cyber spending to grow from offensive and defensive tools into pervasive infrastructure protection across all military systems.
