Stability AI raises $76M Series B from Sony, Universal, Warner and EA

Stability AI has raised $76 million in Series B funding from a group that includes the three major record labels and Electronic Arts, the company said on August 25. The round takes its total funding to $232 million. Stability says that figure covers two equity rounds and convertible notes raised since Prem Akkaraju became CEO in June 2024.

The new names on the cap table are Sony Music Group, Universal Music Group, Warner Music Group and EA, plus two investment firms, AMD Ventures and Pacific Alliance Ventures. Coatue, Greycroft, Kadmos Capital, Sean Parker and Eric Schmidt all came back for a second consecutive round. Coatue co-founder Thomas Laffont joins a board that already seats James Cameron, Sean Parker and Greycroft’s Dana Settle.

This unmatched group of investors is an affirmation of our vision where generative AI empowers every producer, musician, and storyteller.

That roster matters because most of the new strategic investors were already partners. Stability announced an alliance with Universal Music on October 30, 2025 to build music creation tools, then a similar deal with Warner Music on November 19. EA’s partnership embeds Stability’s 3D research team with the publisher’s artists. TechCrunch described the lineup as less a typical venture round than a list of the companies Stability now depends on for content licensing and distribution deals.

The EA deal is the most concrete of the three. In its own write-up, EA says the first joint project is generating 2D textures for physically based rendering materials that keep exact colour and light accuracy across environments. A second track explores systems that pre-visualise entire 3D environments from a series of prompts. Kallol Mitra, EA’s VP of Creative Innovation, framed it as giving artists “the power to dream bigger and build more.”

For the labels, the product is audio. Stability says the round comes on the heels of Stable Audio 3.0, a family of music models it describes as trained on fully licensed data. Three of the four models ship as open weights, while the largest is available through Stability’s API and enterprise self-hosting. The Medium and Large models generate tracks longer than six minutes, and artists can now use them inside a digital audio workstation through a new plugin.

Licensed training data is the whole pitch to the labels, which means the legal record matters. Stability largely prevailed in Getty Images’ UK copyright case over training on the agency’s photos, as TechCrunch notes, but Getty’s US lawsuit is still working through the courts. Our explainer on what AI copyright rulings actually turn on covers why the two jurisdictions can diverge.

The announcement doesn’t include a valuation. The $232 million total also blends equity rounds with convertible notes, which is exactly the kind of detail that a round announcement usually leaves out. What Stability does say is where the money goes: its creative production product suite, an applied research team and a professional services arm. SiliconANGLE reported that the London-based company launched Brand Studio, a cloud service for marketing teams, in April, and that its last open image model was Stable Diffusion 3.5 in 2024.

Even so, the company that made its name on an open image model now leads with licensed music tools, and it’s building them alongside the rights holders themselves. The things to watch are whether Sony Music, the one label in the round without an announced partnership, signs one, and how the US Getty case lands. Both would tell you whether the licensed-data strategy holds up outside the press release.
