Anduril Industries raises $5B Series H at $61B valuation to expand autonomous defense manufacturing

Anduril Industries has closed a $5 billion Series H funding round led by Thrive Capital and Andreessen Horowitz, valuing the defense technology company at $61 billion. CEO Brian Schimpf announced the round will fund manufacturing expansion, R&D, and infrastructure for autonomous aircraft, drones, missile systems, air defense, and AI-powered command-and-control platforms. The company reported 2025 revenue of $2.2 billion, more than double the prior year, and nearly doubled its headcount. Anduril is scaling Arsenal-1, its high-rate manufacturing facility designed to mass-produce autonomous defense systems, directly challenging the traditional defense prime contractor model.

This funding event is structurally significant for the additive manufacturing industry because Anduril has been an aggressive adopter of metal AM for production-grade defense hardware, including LPBF and DED processes for airframe components, missile structures, and sensor housings. The company's Arsenal-1 facility is explicitly designed around rapid, software-defined manufacturing — a production philosophy that aligns with AM's core value proposition of low-volume, high-variety, qualification-intensive output. The $5B raise signals that defense investors now view AM-capable production lines as strategic infrastructure, not experimental R&D. This mirrors the broader defense-vertical acceleration pattern seen since 2025, where NDAA §849 provisions and geopolitical pressure are pulling AM into the defense supply chain faster than aerospace qualification timelines would normally allow. Anduril's model — vertically integrated design, AM production, and software-defined updates — represents a direct challenge to the traditional prime contractor model that has historically constrained AM adoption in defense.

Practically, Anduril must now execute on scaling Arsenal-1 to deliver production-rate autonomous systems, not just prototypes. The company's ability to integrate AM into certified, field-deployable hardware at meaningful volume will be the real test — the funding removes capital constraints but not qualification or supply-chain hurdles. For AM equipment and materials suppliers, Anduril represents a rare Tier S customer: one that designs for AM from the ground up, owns its production facilities, and has the balance sheet to commit to long-term production contracts. The defense vertical's AM adoption curve now hinges less on technology readiness and more on whether Anduril and similar firms can demonstrate that AM-sourced defense hardware meets reliability and cost targets at scale.
