Funding Deals of the Week
Anduril Raises $5 Billion Series H at $61 Billion Valuation
Anduril— $5 Billion
Industry: Defense/ Aviation
Round: Series H
Anduril Industries, the defense technology company, raised a $5 billion Series H round at a $61 billion valuation. The funding round was led by Thrive Capital and Andreessen Horowitz. The funding comes after Anduril reportedly more than doubled revenue to $2.2 billion in 2025 and nearly doubled its workforce over the same period.
The new capital is expected to support Anduril’s continued growth in defense technology, including autonomous systems, advanced surveillance, AI-enabled defense platforms, manufacturing scale-up, and R&D.
Why This Deal Matters
Anduril’s raise highlights how defense tech has become one of the largest venture-backed markets as governments modernize military systems and adopt autonomous, software-driven defense infrastructure.
