Suno's licensed pivot now carries a $9bn legal ceiling

Nine days after Suno launched v6, its first model family built on licensed catalogue, Universal and Sony sued the company a second time. The complaint, filed on 18 September in Boston, asserts 60,202 sound recordings and asks up to $150,000 per work for willful infringement, a statutory ceiling past $9 billion, set against the $5.4 billion valuation Suno raised on in June ¹⁴⁷. Everyone ran the lawsuit. The sharper question is who pays for the pivot: the labels collecting revenue from Suno's deals, the investors holding the round, or the subscribers who lost the product they paid for.

The labels say v6 launders what it inherited

The suit's core claim is that v6 is not the clean break Suno sold. The filing alleges Suno built it through knowledge distillation, a student model reproducing the behaviour of teacher models trained on the unlicensed corpus, plus "user interactions", the preference signals those earlier models generated ²⁴⁸. "Training a 'new' model on the outputs of an infringing model does not eliminate the infringement; it launders it," the complaint states ⁴. Chief executive Mikey Shulman supplied the load-bearing admission himself, telling Billboard↗ the training mix was "partner data" and "user interactions" ⁶.

Suno's own sentences are the exhibits

The filing leans on Suno's words. Since January 2024 its terms of service have demanded from every user a worldwide, irrevocable, sublicensable licence over anything uploaded; a company that demands licences upstream, the labels argue, knew training on audio needs permission, and that showing supports the willful tier ¹. Chief product officer Jack Brody's insistence that the Warner, BMG and Believe revenue shares are "not in exchange for training" is quoted back at him: three deals in under a year "confirm that a functioning market exists" for licensing recordings ¹⁴⁷. Judge F. Dennis Saylor IV pointed the labels down this road on 18 August, refusing to fold 61,026 works into the first case while endorsing a parallel suit ⁴.

Subscribers got the first bill

The earliest cost has landed on users. Suno retired every earlier model when v6 arrived on 9 September, a condition of its November 2025 Warner settlement ⁵⁶. Longtime subscribers describe v6 output as "muffled, dull, and strangely lifeless" and ask for the old models back, Digital Music News reports↗; those models are permanently gone, and the top tier still costs $24 a month ¹³. The likely cause is a far smaller licensed corpus, though Suno has never disclosed what v6 trained on ³.

What a win would reprice

If the laundering theory holds, it reprices every licensing peace deal in generative media: a licence covering new data would not clear weights distilled from tainted teachers, so each settlement carries a contingent liability in exactly this shape. Suno is the market test, with Warner, BMG and Believe collecting revenue from the same company Universal and Sony are billing at the willful tier ¹⁵. The volume backdrop is Deezer's July finding↗ that AI tracks passed half of daily uploads, roughly 90,000 a day ⁹. The decisive constraint remains the first case, 560 works with fair use at its centre and fact discovery closing on 30 September ⁴.
