Suno secures $400 mln funding amid escalating copyright disputes

Suno, the artificial intelligence (AI) company behind a music-generation platform, has recently raised over $400 million in a series D funding round, bringing its valuation to $5.4 billion, even as it continues to face ongoing copyright lawsuits from major record labels.

The Series D round was announced on June 3 and comes roughly seven months after the company’s previous fundraising, which valued it at $2.45 billion. 

The latest funding round was led by Bond Capital, with participation from investors including IVP, Forerunner, Union Square Ventures, Alkeon and Quiet, alongside existing backers such as Matrix, Lightspeed, Menlo Ventures and Schroders Capital. The company has said the round also included participation from unnamed artists, producers and songwriters.

Previously, Suno has acknowledged that its system is trained on copyrighted songs, while arguing that this falls under the legal doctrine of fair use, which allows limited use of protected material under certain conditions. 

The company is facing litigation from major rights holders including Universal Music Group (UMG), Sony Music and the German collecting society GEMA. Warner Music Group has separately reached a licensing agreement with Suno following earlier legal proceedings.

When lawsuits were first filed in 2024 by Sony and Universal, the labels alleged that Suno had used 560 copyrighted works without permission. Subsequent filings have expanded those claims to include allegations that more than 61,000 songs were used in training datasets without authorisation.

Despite the legal pressure, Suno’s platform has continued to gain users. The app has frequently ranked near the top of music charts in app stores.

In a statement published on its blog, Suno said it plans to roll out new music-generation models developed in partnership with the music industry in the coming months.
