Defence technology start-up Anduril Industries said on Wednesday that it has raised $5 billion, doubling its valuation to $61 billion.
The California-based start-up's latest funding round was led by venture capital firms Thrive Capital and Andreessen Horowitz.
Anduril said over the past year, it has more than doubled its revenue to $2.2B in 2025, and nearly doubled its workforce.
Anduril's announcement comes after Reuters reported in March that the company was seeking to raise about $4 billion from Thrive Capital and Andreessen Horowitz.
Anduril was valued at $30.5 billion in a June 2025 funding round.
Defence tech companies have taken centre stage in funding as investors rush to seize the opportunity created by the ongoing U.S.-Iran war.
The availability of abundant private capital is also enabling companies to raise larger funding rounds and remain private for longer.
Anduril develops solutions, including a wide range of sensors and drones, and has gained prominence amid increasing calls for low-cost autonomous defence products.
