Poseidon Wave Media v. Suno: An Independent Label's Revenue-Loss Claim

Case: Poseidon Wave Media v. Suno, Inc. — filed on or around May 19, 2026. 

Not every AI music lawsuit comes from a major label or a class-action law firm. Poseidon Wave Media, the entity behind independent duo The American Dollar, sued Suno in May 2026, alleging that the AI platform's unlicensed use of copyrighted recordings for training has cut the duo's licensing revenue by nearly 80% since Suno launched. Unlike the RIAA-coordinated litigation or the Justice v. Suno class action, this is a single independent rights holder's direct claim — a useful data point for gauging how AI generation has affected working artists and small catalogs outside the major-label system, where licensing revenue often represents a much larger share of total income than it does for a major-label roster act.

The suit adds to a list of copyright actions against Suno that has grown steadily even as the company has settled with the majors: Warner Music Group settled and struck a licensing partnership in November 2025, but Universal and Sony remain active plaintiffs, Germany's GEMA and Denmark's Koda have both filed suit, and the Justice v. Suno class action continues on a separate track. At the time of the Poseidon Wave Media filing, Suno was reported to be raising new funding at a $5 billion valuation, up from a $2.45 billion valuation earlier in 2025 — a trajectory that stands in some tension with the growing docket of infringement claims the company is defending simultaneously.

For independent rights holders considering their own claims, this case is worth watching less for its legal novelty and more as a signal: it suggests plaintiffs' firms and independent labels are treating individual, non-class claims as a viable path against Suno, rather than waiting to see how the larger coordinated actions resolve.
