What happened

Thirty-five local and regional newspaper publishers, together owning nearly 400 newspaper titles, sued Microsoft and OpenAI on 24 June 2026 in the U.S. District Court for the Southern District of New York (Richner Communications, Inc. v. Microsoft Corp., No. 1:26-cv-05320), alleging mass copyright infringement through AI training.

What the publishers allege

The complaint alleges the companies systematically and secretly crawled hundreds of news websites, including paywalled content, copied hundreds of thousands of articles onto their own servers, stripped out copyright management information, and used the material to train large language models behind ChatGPT and Microsoft Copilot — then reproduced the works in responses to user prompts. The publishers include Richner Communications, AIM Media, the Arkansas Democrat-Gazette, CherryRoad Media, Ogden Newspapers, Straus Newspapers, WEHCO Newspapers and Wick Communications, among others. The suit brings three counts, including direct copyright infringement and violations of the Digital Millennium Copyright Act, and seeks statutory damages, actual damages, restitution of profits and attorneys' fees.

Scale of the alleged copying

The complaint cites token counts from C4, a filtered snapshot of Common Crawl used to train GPT-3: Ogden Newspapers accounted for more than 71 million tokens, WEHCO Newspapers for over 6.3 million, and Richner Communications for more than 2.9 million, with more than 115 million tokens across all plaintiffs.

Context

The complaint notes similar suits by The New York Times, the New York Daily News, the Chicago Tribune, the Denver Post, The Intercept and Raw Story, consolidated in multidistrict litigation in the Southern District of New York (MDL No. 1:25-md-03143), and alleges the defendants continued the challenged conduct rather than changing it. The suit was described at filing as the largest legal effort led by local and regional newspapers.

What is not established

All of the above is an allegation in a filed complaint. No finding of infringement has been made, and the defendants have the opportunity to respond.
