CNN just dragged Perplexity into court. The network filed suit in a New York court on Thursday, accusing the AI startup of generating “verbatim” copies of its journalism, according to The Verge AI. The complaint goes further than straight copying: it claims Perplexity hands users CNN content that’s normally locked behind a paywall.
This is the latest hit in a legal pile-up that’s been growing around Perplexity for months. And the specifics here are sharp.
What CNN is claiming
Perplexity runs an AI “answer” engine plus an AI browser called Comet. CNN says the company ignored its attempts “to recognize or block Perplexity’s unidentified crawlers” from scraping its site, then served that scraped work back to users as if it were Perplexity’s own answers.
The lawsuit’s framing is pointed: “Human beings report, research, write, edit, and create the content that Perplexity takes without permission or compensation.”
The most damaging example in the filing is simple to picture. CNN says it typed the title of one of its articles, “What’s next for Minneapolis? A shaky promise, mounting tensions and the fight for control,” into Perplexity’s search tool. The tool allegedly spat back “substantial” verbatim portions of the piece. No clever prompting. Just the headline.
CNN wants two things: damages, and a permanent block on what it calls Perplexity’s unlawful conduct.
A deal that fell apart
What makes this case different from the others is the backstory. These two were close to working together.
Here’s the timeline CNN lays out:
- October 2025: CNN agreed to offer its content through Perplexity’s Comet Plus subscription.
- The talks stalled: The deal “did not lead to a final agreement” over several issues, including how much CNN content Perplexity could pull into its answers.
- November 2025: CNN scrapped the agreement.
- After that: CNN sent a letter demanding Perplexity stop using its content and trademarks. Perplexity allegedly never replied.
That sequence matters. CNN isn’t just claiming Perplexity took its work. It’s claiming Perplexity took its work after a licensing conversation broke down over this exact issue, then went silent on a cease-and-desist.
Perplexity isn’t alone, and isn’t backing down
CNN joins a crowded field. Perplexity is already being sued for copyright infringement by The New York Times, Encyclopedia Britannica, Merriam-Webster, and News Corp, the parent company of The Wall Street Journal. It’s also facing legal action from Amazon and Reddit.
The company’s response to CNN was four words, delivered by spokesperson Jesse Dwyer: “You can’t copyright facts.”
That’s the whole legal fight in one sentence. Perplexity’s defense leans on the idea that facts are free to use. CNN’s case leans on the difference between a fact and the specific, human-written sentences used to report it. Verbatim reproduction is exactly the line where “you can’t copyright facts” stops being a shield.
Why this matters
What stands out here is the shift in tone across the industry. A year ago, publishers and AI companies were mostly racing to sign licensing deals. Now the failed CNN-Perplexity deal shows the other path: when negotiations collapse, the courtroom is the fallback. The pilot becomes the lawsuit.
For anyone building or buying AI search products, three things are worth watching:
- Crawler blocking has teeth as evidence. CNN’s claim that Perplexity used “unidentified crawlers” to dodge blocks is central. How AI companies identify and respect robots directives is becoming a legal question, not just an engineering one.
- Paywall content is its own risk. Serving subscription-only material through an answer engine is a separate allegation from copying. That raises the stakes for any tool that summarizes news.
- “Verbatim” is the keyword. Loose paraphrasing is a murky legal area. Word-for-word reproduction is much harder to defend. Expect AI products to get more cautious about how closely their outputs hug the source.
The outcome of these cases will help draw the boundary between fair use and theft for AI search. CNN is betting that copying its reporters’ exact words crosses that line. Perplexity is betting it doesn’t.
