AI music startup Suno has raised $400 million at a $5.4 billion valuation — double its valuation from seven months ago — making it the highest-valued startup in the AI music space. The company boasts over two million subscribers and is on track for $300 million in annual revenue, with plans to grow its workforce by up to 70% by the end of the year. However, Suno continues to face legal challenges from major record labels Universal Music Group and Sony Music Entertainment, who allege the company used millions of copyrighted recordings to train its AI models, though Warner Music Group previously settled and signed a licensing deal with Suno in November 2025.
