Founders Fund closes $6B growth fund — its largest ever — after burning through $4.6B predecessor in under a year

Tags VC · AI · Infrastructure

Peter Thiel's Founders Fund has closed a $6 billion growth-stage fund, its largest in the firm's 21-year history, assembled in under a year — the fastest succession ever for the firm. The predecessor $4.6B fund was spent in under 12 months despite being planned for 2-3 years, with average checks of approximately $600M across just 7 companies including Anthropic ($1.25B), Anduril ($1B), SpaceX, and OpenAI. Of the new fund, $4.5B came from limited partners including sovereign wealth funds, and $1.5B from firm partners including Thiel himself. The new fund is expected to back about a dozen startups over 2-3 years. The speed and scale signal that top-tier VC firms treat AI as a capital-absorbing megatrend demanding unprecedented fund sizes and deployment velocity.
