In a dramatic legal clash that pits Hollywood's biggest creative powerhouses against Silicon Valley innovation, Disney and Universal have filed a lawsuit against artificial intelligence firm Midjourney, accusing it of systematically looting their most iconic intellectual properties to fuel its explosive growth.

Filed Wednesday in California federal court, the lawsuit brands San Francisco-based Midjourney as a “copyright free-rider” that is cashing in on decades of beloved characters—from Darth Vader and Spider-Man to Shrek and the Minions—without permission, payment, or even a pretense of collaboration.

"Midjourney seeks to reap the rewards of plaintiffs' creative investment," the suit states, calling its AI art tool a “virtual vending machine” for pirated content.

Hollywood vs. AI: The IP War Begins

The complaint, brought by Disney Enterprises, Universal City Studios Productions, and subsidiaries including Marvel, Lucasfilm, 20th Century Fox, and DreamWorks Animation, contends that Midjourney has trained its generative image model on protected content—then used that very content to market its product, generate revenue, and build a subscriber base of nearly 21 million as of late 2024.

At the heart of the dispute is Midjourney’s AI platform, which allows users to generate hyper-detailed images based on text prompts. The plaintiffs argue that it doesn’t just draw inspiration—it reproduces protected works outright.

"A simple request for ‘Darth Vader riding a dragon’ yields an image that unmistakably depicts Disney's Darth Vader," the suit alleges.

Cease and Ignored: Studios Say Warnings Went Unheeded

The lawsuit chronicles a paper trail of ignored legal warnings. Disney first contacted Midjourney in November 2024, flagging unauthorized uses of characters from The Simpsons, Star Wars, Spider-Man, and more. Universal followed with its own warning in May 2025, citing infringing images from Shrek, Kung Fu Panda, and Despicable Me.

Despite those letters, the studios say Midjourney “doubled down”—not only ignoring the requests but teasing a new AI video-generation tool rumored to be trained on the same IPs.

"Piracy is piracy, and whether an infringing image or video is made with AI or another technology does not make it any less infringing," the studios wrote in their complaint.

$300 Million Revenue — and Rising

Midjourney, launched in 2022, has surged to financial heights few startups achieve so quickly. According to the suit, the AI firm raked in $200 million in 2023 and soared past $300 million in 2024, largely driven by paid subscriptions for its image-generation service.

That success, Disney and Universal argue, is directly tied to their own creations—characters, stories, and visuals built on decades of storytelling and billions in investment.
