Mach Industries hits $1.8B valuation as autonomous defense funding keeps accelerating

Mach Industries is not a generic defense-tech funding item; it is a signal that autonomy and AI-adjacent systems are still pulling enormous capital into defense. TechCrunch reports that the three-year-old startup raised a $300M Series C at a $1.8B valuation, up from a $470M valuation in June 2025. The round was led by Infinite Capital and Ribbit Capital, with Bedrock Capital, Sequoia, and Khosla also listed. Founder Ethan Thornton said the company originally went out to raise $200M and pushed the round to $300M after being oversubscribed. Mach is developing five autonomous vehicles: Viper, Glide, Stratos, Dart, and Pike, with production expected next year on at least three. The story matters because defense autonomy is becoming a core AI capital lane, even when the products are aircraft, interceptors, and munitions rather than chatbots.

Key details: Mach Industries, June 1, 2026, $300M Series C, $1.8B valuation, $470M valuation in June 2025, Infinite Capital, Ribbit Capital, Viper.
