Suno raises $400M Series D, doubling valuation to $5.4B

AI music startup Suno has raised more than $400 million in a Series D funding round, giving the company a post-money valuation of $5.4 billion. The round is one of the largest to date in the generative AI music space and comes only months after Suno’s prior $250 million raise, which had valued the company at $2.45 billion. The new capital was announced on June 3, 2026, and marks a rapid more-than-doubling of the company’s valuation in roughly half a year, underscoring strong investor conviction despite ongoing legal and regulatory scrutiny around AI-generated music.

The Series D round was led by Bond Capital, an investor also known for backing OpenAI, with participation from IVP, Forerunner, Union Square Ventures, Alkeon, and Quiet. Existing investors Matrix, Lightspeed, Menlo Ventures, and Schroders Capital also joined the round, alongside undisclosed artists, songwriters, and producers from the music industry. Suno plans to use the funding to enhance its AI music creation platform for artists and everyday users, and to roll out its first music model built in partnership with major music industry rights holders, including Warner Music Group. The size and valuation of this round position Suno as one of the most highly valued companies in AI-generated content and signal that mainstream music and financial stakeholders view AI music as a core part of the industry’s future.
