AI Coalition for Data Integrity and nine groups file brief backing publishers in OpenAI copyright MDL

What happened

On 30 October 2026, the AI Coalition for Data Integrity (AICDI) and nine other organizations filed a proposed amicus brief in support of the plaintiffs' motions for summary judgment in In re OpenAI, Inc. Copyright Infringement Litigation, the consolidated multi-district case against OpenAI and Microsoft before Judge Sidney Stein in the Southern District of New York (No. 1:25-md-03143, ECF 2386-1).

Who joined

AICDI was joined by Writers Guild of America West and East, the National Association of Voice Actors, Microstocksolutions LLC, the Digital Media Licensing Association, Transparency Coalition AI, the Association of Medical Illustrators, the Association of Independent Music Publishers (AIMP), and the Music Workers Alliance.

What the brief argues

The brief argues that a licensing market for AI training already exists and that protection is not circular: it points to the Munich Regional Court's first-instance rulings in GEMA's cases against OpenAI and Suno as a foreign collective-licensing clearance model. It argues that documented training-data provenance serves national security, that developers trade training data (proving its value), that opaque acquisition suppresses licensing, that paywall crawling defeats any implied licence from opt-out failure, and that provenance rules protect smaller developers. It also argues that outputs need not resemble a work to cause harm and that unlicensed use creates a 'doom loop' for content creation.

Status

This is an amicus filing in support of the plaintiffs' summary-judgment motions, not a ruling. The court has not decided the fair-use question.
