Sony Music sues Udio for up to $4.5 billion over 30,117 recordings

Two major labels signed peace deals with AI music startup Udio. Sony looked at the same deal and filed a lawsuit for up to $4.5 billion instead.

The new lawsuit

On July 20, 2026, Sony Music and nine of its labels sued Udio in Manhattan federal court, accusing the AI music generator of copying 30,117 of its recordings to train models without a license.

Why a second lawsuit?

Sony already has a case against Udio from 2024, and it tried to fold these songs into it. In June, the judge refused, ruling that adding them would derail the trial. So Sony simply started a new war on a second front.

The math explains the move, and it is brutal: statutory damages exposure jumps from roughly $50 million in the original case to as much as $4.5 billion with the new recordings in play. The second filing is not procedural housekeeping; it is a 90x escalation of the stakes.

The last label standing

The context makes it spicier. Universal and Warner both settled with Udio in late 2025 and signed licensing deals, converting their lawsuits into revenue streams. Sony is now the last major label still fighting, betting that a courtroom win is worth more than a licensing check.

That bet has consequences far beyond one startup. Whatever the verdict, it will help define the price of training AI on culture: settle-and-license produces a market rate, but a judgment produces a precedent, and a $4.5 billion precedent would echo through every training-data negotiation in the industry.

Every AI company is watching this number. If Sony wins big, the cost of training on copyrighted culture gets a courtroom price tag. If Udio prevails, the settlements Universal and Warner signed start to look like insurance against a risk that never materialized. Either way, the ruling will be a landmark.
