**Runway AI raised $315 million in a Series E round at a $5.3 billion valuation**, announced on February 10, 2026 and led by **General Atlantic**. The round pulled in a notably wide mix of strategic and crossover backers, including two chipmakers and a major publisher.

Here's the full breakdown of the raise, who backed it, and why the valuation jump matters.

## What is Runway AI?

Runway is an **AI platform for generative media creation**, specializing in physics-aware world models for video generation — systems designed to simulate physics and predict how an environment evolves, with applications reaching beyond video into robotics training and interactive environments. Founded in **2018** by **Cristóbal Valenzuela, Anastasis Germanidis and Alejandro Matamala**, Runway was one of the earliest companies to commercialize generative video.

## The raise: $315M Series E

The headline numbers:

- **Amount:** $315 million
- **Round:** Series E
- **Valuation:** $5.3 billion
- **Announced:** February 10, 2026
- **Lead investor:** General Atlantic

Runway's previous round was a **$308 million Series D at a valuation north of $3 billion**, closed in April 2025. Going from roughly $3 billion to $5.3 billion in about 10 months is a **76% jump** — a steep climb even by 2026's AI-funding standards, and it follows a string of earlier rounds: a $2 million seed in 2018, an $8.5 million Series A in December 2020, a $35 million Series B in December 2021, a $50 million Series C in December 2022, and a $141 million Series C extension in June 2023.

## Who invested in Runway AI?

The Series E was led by **General Atlantic**. Additional participants included:

- **NVIDIA**
- **Adobe Ventures**
- **AMD Ventures**
- **Fidelity Management & Research Company**
- **Mirae Asset**
- **Emphatic Capital**
- **Felicis Ventures**
- **Premji Invest**
- **AllianceBernstein**

Having both NVIDIA and AMD Ventures in the same round is notable — it suggests Runway's compute needs, and its ambitions for physics-aware world models, are significant enough to draw interest from rival chipmakers at once.

## What Runway AI will do with the money

Runway said the funding will go toward **pre-training its next generation of world models**, bringing those models to new products and industries including medicine, climate, energy and robotics, expanding team capacity, and scaling Runway Studios, its AI film and animation production arm.

## Why it matters

1. **World models are pulling investor attention away from narrow generative video.** Runway's pitch has shifted from "make video from text" to building foundational systems that simulate physics — the kind of technology robotics and autonomous systems need to predict how the real world behaves.
2. **The valuation trajectory shows how fast conviction is building.** A 76% jump in 10 months, on top of a $308 million round the year before, puts Runway among the fastest-appreciating companies in the [biggest AI funding rounds of 2026](/blog/biggest-ai-funding-rounds-2026).
3. **Runway's raise sits alongside a broader wave of AI video funding.** It's one of several generative-media companies raising at scale this year, a trend tracked in [AI video startup funding for 2026](/blog/ai-video-startup-funding-2026).
