The Suno lawsuit is a copyright case filed in June 2024 by the three major record companies against Suno, Inc., a Cambridge-based AI music startup, alleging that Suno trained its song-generating model on millions of copyrighted recordings without a license. The case is pending in the U.S. District Court for the District of Massachusetts before Chief Judge F. Dennis Saylor IV, and after Warner Music Group settled and signed a licensing deal in late 2025, Universal Music Group and Sony Music are pressing forward with claims that could exceed $9 billion in statutory damages.1Complete Music Update.

What the Labels Sued Over
The complaint was filed on June 24, 2024, under case number 1:24-cv-11611. The plaintiffs, a group of labels under UMG, Sony, and Warner (including Capitol Records, Atlantic Recording Corporation, and Warner Records), allege that Suno copied and ingested vast quantities of copyrighted sound recordings to train its AI model, in violation of the Copyright Act and the Music Modernization Act. The Recording Industry Association of America coordinated the litigation.2RIAA. Record Companies Bring Landmark Cases for Responsible AI Against Suno and Udio
The original complaint attached a “non-exhaustive, representative list” of 560 copyrighted works as examples while asserting Suno had used millions of the labels’ recordings.3Music Business Worldwide.

Suno’s platform generates full songs, with vocals and instrumentation, from a text prompt in seconds. By early 2026 the company reported more than 100 million users and 2 million paid subscribers, and a June 2026 Series D round valued it at $5.4 billion.4Variety.

What Suno Admits and How It Defends Itself
Suno has not denied training on copyrighted music. In its answer, the company acknowledged that “the tens of millions of recordings that Suno’s model was trained on presumably included recordings whose rights are owned by the Plaintiffs.”6Music Business Worldwide. UMG and Sony Seek to Add 61,000 Copyrighted Works to Suno Lawsuit Suno separately described its training set as including “essentially all music files of reasonable quality accessible on the open internet,” excluding only content behind paywalls or password protection.7Soundiiz. The Music Industry Is at War Against AI Suno and Udios Case
Suno’s defense rests on the fair use doctrine at 17 U.S.C. § 107. The company argues that training an AI model on existing recordings is “transformative” because the model learns patterns and generates new works rather than reproducing the originals.8Transparency Coalition.

The YouTube Stream-Ripping Allegations
In September 2025 the labels filed an amended complaint adding a claim under the Digital Millennium Copyright Act’s anti-circumvention rules (17 U.S.C. § 1201). They allege Suno wrote code to bypass YouTube’s “rolling cipher” encryption to extract and download copyrighted recordings for training. The RIAA is seeking $2,500 in statutory damages for each act of circumvention, on top of per-work copyright damages.10The Verge. RIAA Suno AI Lawsuit Update Stream-Ripping YouTube
Suno moved to dismiss the DMCA claim in October 2025, arguing that § 1201 only prohibits circumventing “access controls,” not “copy controls.” In the company’s words, “A copy control does not become an access control simply by hiding the underlying file, when the content of that file is streamed for everyone in the world to see and hear on demand.”116AM Group. Suno Fires Back Against Major Labels Proposed Amended Complaint The labels responded by pointing to the Second Circuit’s decision in Universal City Studios v. Corley for the proposition that fair use does not authorize circumventing technical protection measures.12Music Business Worldwide.

How the Case Grew to 61,000 Recordings and $9 Billion
Discovery reshaped the scale of the case. Using Audible Magic, an audio fingerprinting service, UMG and Sony identified thousands of their specific recordings inside Suno’s training data. On May 21, 2026 they moved to amend the complaint to add 61,026 specific works, which they called “only a small fraction” of the total copyrighted material found in the dataset. The labels blamed Suno’s “ongoing refusal to provide Plaintiffs with the data in its possession” for the delay in identifying works.6Music Business Worldwide. UMG and Sony Seek to Add 61,000 Copyrighted Works to Suno Lawsuit
Under U.S. copyright law, statutory damages can reach $150,000 per willfully infringed work. Expanding the formal list from 560 to 61,026 recordings pushed the theoretical maximum from roughly $84 million to more than $9.1 billion.1Complete Music Update. Damages in Major Label Lawsuit Against Suno Could Top $9 Billion
Suno opposed the amendment on June 4, 2026, arguing the labels had “unduly delayed” the request and urging the court to make them file a separate lawsuit rather than “undertake a wholesale rewriting of this one.”3Music Business Worldwide.

Warner Music’s Settlement and Licensing Deal
Warner Music Group broke ranks first. On November 25, 2025 WMG announced it had settled its claims and entered into a licensing partnership with Suno, described as a “first-of-its-kind” arrangement.13Warner Music Group. Warner Music Group and Suno Forge Groundbreaking Partnership The settlement reportedly included a “multi-million dollar” payment from Suno.14TechCrunch. Warner Music Signs Deal With AI Music Startup Suno Settles Lawsuit Key terms included:
- WMG artists and songwriters retain full control over whether their names, images, likenesses, voices, and compositions can be used in AI-generated music.
- Suno committed to launching new AI models trained on properly licensed music in 2026, at which point its current models would be retired.
- Downloads of AI-generated audio will require a paid account; free-tier users can play and share but not download, and paid tiers include monthly caps.
- Suno acquired Songkick, the live-music discovery platform, from WMG as part of the deal.15Los Angeles Times. Warner Music Group Suno AI Lawsuit Settlement
WMG CEO Robert Kyncl called the deal a “victory for the creative community.” Suno CEO Mikey Shulman said it unlocked a “bigger, richer Suno experience.”13Warner Music Group. Warner Music Group and Suno Forge Groundbreaking Partnership Warner then dismissed its claims.
Reception among artists was mixed. The Music Artists Coalition, the Artist Rights Alliance, and other groups released an open letter calling Suno a “brazen ‘smash and grab’ platform” that built its business by “scraping the world’s cultural output without permission,” and cited Deezer research suggesting up to 85% of streams on fully AI-generated music are fraudulent.16Billboard. Say No to Suno Artist Groups Challenge AI Music Training Veteran manager Irving Azoff called the label-AI deals “biting cynicism,” saying “everyone talks about ‘partnership,’ but artists end up on the sidelines with scraps.”17The Guardian.

Where UMG and Sony Stand Now
Universal and Sony remain the active plaintiffs, and as of April 2026 settlement talks with Suno were at what reporting called a “hard impasse.” The dispute centers on the “walled garden” question: whether AI-generated tracks can be shared and distributed outside the Suno platform. UMG chief digital officer Michael Nash has said Suno’s refusal to accept a walled-garden model is the main reason it hasn’t settled. Suno chief music officer Paul Sinclair has argued walled gardens stifle innovation.16Billboard. Say No to Suno Artist Groups Challenge AI Music Training
A summary judgment hearing on Suno’s fair use defense is scheduled for July 2026 before Chief Judge Saylor.18Tech Times.

Suno Moves to Keep Size of Its AI Training Data Sealed Citing Competitive Harm Sony, which has declined to settle with either Suno or Udio, has been described as “betting on a court ruling that establishes the precedent the entire industry will live under.”
The Anthropic Ruling That Could Shape the Outcome
Both sides are watching a decision from a different case. In June 2025, Judge William Alsup of the Northern District of California issued a split ruling in Bartz v. Anthropic, a lawsuit over copyrighted books used to train the Claude language model. Judge Alsup ruled that using copyrighted works to train an AI model is “exceedingly transformative” and constitutes fair use, comparing the process to a student learning from existing works. He drew the line at acquisition: Anthropic’s use of pirated copies was not fair use, and the company faced potential liability for that regardless of how transformative the model was.20Copyright Alliance. Bartz v. Anthropic Order
That distinction matters for Suno because the labels have specifically alleged the training data was obtained by stream-ripping YouTube, which they characterize as piracy. Under the Bartz framework, Suno’s fair use defense could succeed on the training question and still fail on the sourcing question. Federal courts remain divided on how to weigh transformative purpose against market harm, so the outcome is not settled.21White & Case.

Other Lawsuits Suno Faces
The major-label case is not the only action against Suno.
- An independent artist class action, Justice v. Suno, is also pending before Chief Judge Saylor in Massachusetts; the court took Suno’s motion to dismiss under advisement after a March 20, 2026 hearing. A second class action, Nguyen v. Suno Inc., was filed in the Northern District of California in November 2025, alleging roughly 60% of the 40 million tracks in Suno’s training data came from independent artists.22CourtListener.

The Massachusetts case is the one carrying the biggest damages figure and the fair use question that could set the template for AI training across creative industries. Whatever Chief Judge Saylor rules on summary judgment will land at the center of that debate.
