Suno, an AI music-generation company, announced a $400 million Series D funding round, valuing the company at $5.4 billion. This latest round comes approximately seven months after Suno raised funds at a $2.45 billion valuation, suggesting strong investor confidence despite ongoing litigation.
Suno has acknowledged that it trains its AI using copyrighted songs and asserts that this falls under fair use, a legal doctrine permitting limited use of copyrighted materials without permission. However, the application of fair use can vary significantly in different cases.
Copyright holders, including Universal Music Group (UMG), Sony, and the German music organization GEMA, are pursuing legal action against Suno. Warner Music Group (WMG), however, settled with Suno last November and reached a licensing agreement.
In 2024, UMG and Sony sued Suno, initially claiming the company trained its AI on 560 of their copyrighted works. That figure has since escalated; last month, the labels amended their complaint to allege that Suno used over 61,000 additional songs for training without authorization.
Despite these legal challenges, Suno continues to perform well in the market, frequently ranking near the top of the App Store charts for music. During its Series C funding round, user-generated content on Suno reached over 7 million songs daily, according to a pitch deck.
The Series D round was led by Bond Capital and included participation from IVP, Forerunner, Union Square Ventures, Alkeon, and Quiet. Existing investors such as Matrix, Lightspeed, Menlo Ventures, and Schroders Capital also contributed to the funding.
Suno expressed enthusiasm about the involvement of certain high-profile artists, producers, and songwriters but did not disclose any names. The lack of named endorsements is significant, as they could help counter the perception that the music industry is largely opposed to Suno’s initiatives.
