Correction (October 9, 2026): An earlier version of this article stated a $4.5 billion valuation, listed investors who were not in the round, and included quotes attributed to Runway and its CEO that WikiDigit never obtained. We have rewritten the article from the sources linked below and removed every claim we could not verify.

Runway, the New York company behind the Gen series of AI video models, raised a $308 million Series D led by General Atlantic, the company announced on April 3, 2025. Fidelity Management & Research Company, Baillie Gifford, NVIDIA and SoftBank Vision Fund 2 also invested, alongside other new and existing backers.

How much is Runway worth?

Runway did not disclose a valuation. Bloomberg reported that the round values the company at just over $3 billion, citing people familiar with the matter, and that the deal closed late in 2024 before it was announced.

What the money is for

In its announcement, Runway said the funding will go to two things:

  • Runway Studios, its in-house film and animation production arm, which it plans to expand.
  • Research into AI models for media, along with continued hiring of researchers and engineers.

Why the timing matters

The round was announced days after Runway released Gen-4, a video model it launched on March 31, 2025, with a focus on keeping characters, objects and locations consistent across shots. Consistency has been one of the main obstacles to using generated video in real productions, where the same person or set has to look the same from scene to scene.

The investor list is a mix of late-stage funds and a strategic backer: NVIDIA supplies the chips video models are trained and run on. Runway does not publish revenue figures, so how much of the valuation rests on current sales versus expected growth is not public.

The competition

Runway is one of several companies building video generation models, alongside OpenAI's Sora and Google's Veo. Its pitch is less about the model alone and more about tools for working filmmakers and studios, which is where the Runway Studios expansion fits.
