Suno doubles its valuation while labels press a 61,000-song claim

Investors are still paying growth prices for AI music, even while the copyright fight gets larger. TechCrunch reported at 8:31 AM PDT on June 3, 2026, that Suno raised a $400M Series D round, valuing the AI music-generation company at $5.4B. About seven months earlier, Suno’s valuation was $2.45B.

Bond Capital led the round, with IVP, Forerunner, Union Square Ventures, Alkeon, Quiet, Matrix, Lightspeed, Menlo Ventures, and Schroders Capital among the investors. The funding suggests that backers see consumer demand and music-creation workflows as large enough to justify more capital before the legal picture is settled. TechCrunch cited earlier pitch materials saying users were generating more than 7M songs per day on Suno at the time of its Series C.

The legal exposure is central to the story. Suno has acknowledged training on copyrighted songs and argues that its use is protected by fair use. Universal Music Group, Sony, and GEMA continue to pursue litigation, while Warner Music Group settled last year and reached a licensing deal. The labels have also moved to expand their complaint, alleging that more than 61,000 additional songs were used for training without permission.

That makes the $400M round more than a startup-financing headline. It gives Suno more room to fund litigation, negotiate licenses, and keep shipping while courts test how far fair use reaches for generative music. The next signal to watch is whether Suno signs more rights-holder deals or keeps relying mainly on the legal argument that model training is permissible. In AI copyright, capital is arriving faster than legal certainty.
