CNN Sues Perplexity, Escalating the Media Industry’s Showdown Over AI Content Use

CNN filed a lawsuit against AI search startup Perplexity on May 28 in Manhattan federal court, accusing the company of scraping more than 17,000 of its news stories, photos, and videos without permission. The complaint alleges Perplexity used that material to train its systems and generate responses that sometimes reproduce CNN’s content word-for-word.

This is CNN’s first legal action against an AI firm. It follows similar suits from Dow Jones, The New York Times, and others who argue their reporting is being repurposed by chatbots and answer engines without compensation. Perplexity, valued in the tens of billions, has already faced multiple copyright complaints.

CNN attempted a licensing deal with Perplexity last year, but negotiations broke down over how the AI would present the network’s material. After talks failed, CNN blocked Perplexity’s web crawler. The complaint says Perplexity knew it lacked authorization both before and after those discussions.

“CNN’s lawsuit stands for the proposition that Perplexity should not be able to steal from entities that create the original content it exploits,” a CNN spokesperson said. The network noted it has commercial AI partnerships, including one with Meta, but drew a line: “If they refuse to pay through sensible licensing, they will have to pay through legal damages. There is no free option.”

Perplexity responded that “you can’t copyright facts,” arguing its retrieval-augmented generation system simply summarizes publicly available material. But CNN alleges the system copies content at scale, delivers summaries that substitute for visiting CNN.com, and even suggests to subscribers that it offers access to CNN’s exclusive content—a claim the network says is false.

The case joins more than 100 copyright actions against AI developers since 2023. No appellate court has yet ruled definitively on whether training models on copyrighted news articles constitutes infringement or fair use. Lower courts have sent mixed signals.

Legal experts note the key question: Does Perplexity’s output copy protected expression, or just facts? If the outputs reproduce CNN’s structure and phrasing at length, the infringement claim gains strength. Short factual summaries might fall under fair use.

CNN seeks statutory damages and an injunction barring Perplexity from using its content. The outcome could shape how AI search tools operate and whether news organizations can sustain original reporting in an era of instant machine-generated answers.
