Top Defense & Space Startups 2026: Biggest Rounds, Most Valuable Companies & Top Investors

Value Add VC has tracked 47 Defense & Space venture rounds in 2026 totaling $18.7B, including 9 rounds ($527M) in Q4 2026. Ranked below: the biggest rounds, the companies that raised the most in 2026 and the ones with the highest reported valuations, and the most active lead investors.

Defense tech, space and government-technology startups. Private companies only; rounds tracked by Value Add VC, not a market total.

Methodology

Rounds tracked by Value Add VC from filings, wire releases and news outlets — not a total for the whole market or a complete list of every Defense & Space company. Data window: 2026 year-to-date for the biggest rounds, the companies that raised the most, and lead-investor rankings. Companies by valuation show each company's latest reported valuation (since mid-2025) — an older figure is left off rather than shown as current.

Ranked by dollar amount (rounds, companies by funding), by latest reported figure (companies by valuation), and by number of tracked deals led (investors). Public companies, debt, fund closes, acquisitions and unverified/rumored rounds are excluded.
