Runway, the generative AI startup redefining media production, has secured $308 million in Series D funding to advance its AI research and expand its film and animation studio, Runway Studios. The round was led by General Atlantic, with participation from Fidelity, Baillie Gifford, Nvidia, SoftBank, and others.
The company said the investment marks a pivotal step in building a new media ecosystem powered by AI “world simulators.” Runway recently launched Gen-4, a video model capable of generating consistent characters and scenes with multi-angle coherence. Co-founder Cristóbal Valenzuela said these tools represent a foundational shift in storytelling. Runway aims to reach $300 million in annualized revenue by year-end.
