Suno raises $400 million at $5.4 billion valuation

Suno, the AI music-generation company, announced on Wednesday that it has raised a $400 million Series D round. The late-stage funding round values the company at $5.4 billion. This represents an increase from its previous valuation of $2.45 billion, which was established about seven months ago. The valuation jump underscores that investors remain confident in the company’s future despite the litigation it faces.

Still facing copyright lawsuits, the company’s legal challenges remain a central focus. That legal trouble isn’t minor. As Suno itself has admitted, the company trains its AI on copyrighted songs. Suno argues that training on copyrighted songs is permissible under fair use—which is a legal doctrine that allows limited use of copyrighted material without permission. However, major record labels and music organizations are continuing their legal battles. Universal Music Group, Sony, and German music collection organization GEMA are pursuing legal action against Suno. When Sony and Universal Music Group initially sued Suno in 2024, the companies claimed that Suno had trained on 560 of their copyrighted works. Last month, the record labels filed to amend their complaint to allege that over 61,000 songs were used for AI training without permission.

Despite the legal pressure, Suno continues to see high user engagement. According to a pitch deck obtained by Billboard, users were generating over 7 million songs on Suno every day at the time of its previous funding round.

The late-stage funding round was backed by a consortium of investors:

• Bond Capital (which served as the lead investor)
• IVP
• Forerunner
• Union Square Ventures
• Alkeon
• Quiet
• Matrix (existing investor)
• Lightspeed (existing investor)
• Menlo Ventures (existing investor)
• Schroders Capital (existing investor)

While other major labels continue their legal actions, Warner Music Group settled and reached a licensing deal with Suno last November. In announcing the new funding, Suno stated it is “thrilled to have participation from some of the best artists, producers, songwriters, and people from across the music industry,” though the company did not disclose any specific names of these partners.

Why it matters

Suno’s valuation jump highlights a growing divide in the AI industry: while major labels fight to protect intellectual property, investors are betting that AI-generated content will become a dominant force in the music market regardless of the legal outcome.
