Runway

Market position

Runway is best known for physics-aware AI video generation and competes with video-generation offerings from OpenAI and Google; Gen-4.5 was reported to outperform both on several benchmarks. In world models it competes with Fei-Fei Li's World Labs and Google DeepMind. Runway was selected by Time magazine in June 2023 as one of the 100 Most Influential Companies.

Runway positions a single family of underlying world and media models across three delivery surfaces (creative suite, developer API, robotics simulation), combined with studio-specific custom models such as the Lionsgate model trained on more than 20,000 titles, an in-house production arm, and benchmark-leading video quality.

Technology

Runway develops proprietary foundation models for generative media and what it terms Real-World Intelligence: GWM-1, a general world model used for simulation and robotics policy inference, and Gen-4.5, a video model supporting high-definition text-to-video with native audio, long-form multi-shot generation, character consistency and advanced editing. World models construct internal representations of an environment to plan for future events. Earlier work includes co-development of the Stable Diffusion latent diffusion text-to-image model. Compute capacity is supported by a deal with CoreWeave.

Go-to-market

A freemium self-serve creative platform (free trial, cancel anytime) alongside developer API sign-up, enterprise tiers and contact-sales motions for robotics. Runway also builds visibility through its annual AI Film Festival, begun in 2023 with 300 submissions and growing to over 6,000 submissions in 2025, and a partnership with the Tribeca Film Festival since 2024, plus funding earmarked for films made with AI-produced footage.

Individual creatives and teams of all sizes, developers building on media models, enterprises in media, entertainment and advertising, and — more recently — gaming and robotics customers. Named users and partners include Lionsgate, AMC Networks, Adobe and Chime.

Geography

Headquartered in Manhattan, New York City, serving customers worldwide, with London announced as European headquarters and world model research hub alongside a planned $100 million investment in the UK AI ecosystem and a newly appointed Head of Europe.

History

Following its 2018 founding and a $2 million seed round the same year to build a platform for deploying machine learning models in multimedia applications, Runway raised an $8.5 million Series A in December 2020, $35 million Series B in December 2021, and a $50 million Series C in December 2022 at a $500 million valuation, extended in June 2023 with $141 million at a $1.5 billion valuation from investors including Google, Nvidia and Salesforce. In August 2022 it co-released Stable Diffusion. It raised $308 million in April 2025 led by General Atlantic at a valuation above $3 billion, released the Gen-4 model that month, released its first world model in December 2025, and raised a $315 million Series E in February 2026 at a $5.3 billion valuation. Alongside product releases it has built media-industry partnerships with Lionsgate (2024), AMC Networks (2025) and Adobe, and announced a London European headquarters and world model research hub.

Risks & controversies

Artists have brought a lawsuit against Runway and other generative AI companies alleging that models were trained on copyrighted artwork without permission; Runway argues the fair use doctrine shields it, and the outcome remains undetermined. The company also operates in a highly compute-intensive market with strong competition from OpenAI, Google and other world-model labs.
