Official DOD AI line item: $1.8B. Actual AI-related spend across all programs: estimated $5–10B annually — and climbing fast. Frontier model contracts worth $800M went out in 2025 alone.

Choose your depth. The data doesn't change — just the explanation.
The US military says it spends $1.8 billion on AI. The real number, once you add up all the AI hidden inside weapons programs and intelligence budgets, is probably $5 to $10 billion a year — and growing fast.
The $1.8B 'AI' line item omits: DARPA AI research (~$1B+), AI embedded in weapons programs like the F-35, classified intelligence community AI, and the 2025 CDAO contracts ($200M each to OpenAI, Anthropic, Google, and xAI). Total estimated: $5-10B. The Pentagon has effectively become the largest early customer for every frontier AI company.
All non-official figures are estimates derived from public contract awards, press releases, and Congressional Research Service reports — not from classified budget documents. Anduril's $20B Army contract (IVAS/robotic combat vehicle) is public. CDAO OTA contracts ($200M × 4) confirmed by DOD press releases July 2025. The true intelligence community AI spend is unknown; $5-10B total is a conservative floor.

The Real Budget Breakdown
The official AI line item is the smallest slice. Everything else is hidden inside program offices, R&D accounts, and classified budgets.

🚀 Anduril: $20B Contract, 7 Years Old
Anduril was founded in 2017. By 2024, it had secured a $20B 10-year Army contract for autonomous combat systems. For comparison, that's larger than total US foreign aid to most countries. The new defense primes aren't Lockheed and Raytheon — they're Silicon Valley-born companies building AI-first weapons.
The New Defense Primes
AI-native companies are displacing legacy defense contractors. Anduril, Palantir, Scale AI, and Shield AI now hold positions that would have been unimaginable in 2015.
