What happened in UMG v. Suno? (plain-language case tracker)

Timeline from the docket (1:24-cv-11611, D. Mass.)

• June 24, 2024 — UMG Recordings, Capitol, Sony Music, Warner-family plaintiffs and others file suit, alleging Suno trained its model on their copyrighted recordings without license.
• December 2025 — the six Warner plaintiffs stipulate that their claims against Suno "are hereby dismissed with prejudice" — the stipulation's own words (Dkt. 174), expressly not affecting the other plaintiffs; the court enters the order January 28, 2026. With prejudice means they cannot refile. In parallel, Warner announces a licensing partnership with Suno — the deal's terms are not on the docket and remain not publicly disclosed.
• April 2026 — remaining plaintiffs file an objection concerning Suno's licensing agreement with Warner and its effect on the case.
• May 2026 — UMG, Capitol and Sony move to amend the complaint a second time.
• July 9, 2026 — hearing before the magistrate judge; the docket passed 250 entries this month.
• August 19, 2026 — UMG, Capitol and Sony remain active plaintiffs. The case is still in pretrial litigation; no merits ruling has appeared.

What has NOT happened in this case?

No ruling on fair use. No trial. No finding that training was or wasn't infringement. The case's eventual answer to the training question — if it gets there before more settlements — would be the first of its kind for music. Until then, every "the Suno lawsuit decided X" claim you read is wrong, including at least one citation to a case that doesn't exist (see our Bartz v. SoundAI investigation).
