Defense tech is the secondary market's quiet outperformer. The cohort that was almost untouchable to most institutional buyers a decade ago — defense primes don't fit ESG mandates, the contracting cycles are slow, the political risk is real — has become one of the most aggressively bid sectors on private secondaries across the broader private company marketplace. Investors exploring why institutional capital has shifted toward defense-focused private companies should review the complete guide to pre-IPO investing before evaluating secondary pricing dynamics in the sector.

What's driving demand

Three forces are reshaping the buyer base. Sovereign wealth funds, particularly from Gulf and Asian allies, are deploying aggressively into US defense tech as a strategic and financial bet. Family offices are over-indexing here as a hedge against geopolitical uncertainty. And a wave of US institutions has quietly relaxed defense exclusions in the last 18 months, freeing up capital that was previously sidelined.

Supply remains soft

The defense tech cohort is unusual on the supply side. Companies like Anduril and Shield AI have run smaller, more selective tender programs than peers in AI or fintech. Founder shareholders and early employees tend to hold longer — partly mission alignment, partly the tax mechanics of QSBS for early-issued common. The result is consistently thin secondary float.

What that means for pricing

Tight float plus aggressive demand has compressed the discount to last primary mark to near zero, and at peak demand windows we've seen secondaries clear above the last primary. That's unusual in private markets — secondaries usually trade at 5–15% below the most recent preferred — and it tells you something real about where this cohort is in the cycle.

What to watch

  • Tender announcements at Anduril and Shield AI; both run irregular tender windows
  • DoD contract awards — these move secondary marks faster than the underlying business fundamentals warrant
  • Sovereign LP allocations; concentration here matters and the desk tracks it closely
