CNN has filed a lawsuit against Perplexity AI in a New York court, accusing the AI search startup of generating verbatim copies of its journalism and providing users with content that sits behind CNN's paid subscription wall. The lawsuit, filed on Thursday, makes CNN the latest in a growing line of major media organisations taking legal action against Perplexity over what they describe as systematic unauthorised use of their content.

What CNN Is Alleging

The lawsuit claims that Perplexity's AI tools reproduce substantial portions of CNN's reporting without permission or compensation, using content scraped from CNN's website by crawlers the company says it repeatedly tried to identify and block. In one specific example cited in the filing, CNN says that entering the title of one of its articles into Perplexity's search tool produced significant verbatim portions of the article's text. The complaint states that human beings report, research, write, edit, and create the content that Perplexity takes without permission or compensation.

CNN also alleges that Perplexity gives users access to content locked behind its subscription paywall, effectively allowing non-subscribers to access premium journalism they have not paid for by routing the request through Perplexity's interface. CNN is seeking financial damages and a permanent injunction against Perplexity's alleged conduct.



The Failed Partnership

The lawsuit follows a breakdown in negotiations between the two companies. CNN had been in discussions to formally license its content through Perplexity's Comet Plus subscription service, announced in October 2025. Those talks collapsed in November 2025 after the parties could not agree on terms, particularly around limits on how Perplexity could use CNN content in its answers to users. CNN subsequently sent a letter demanding that Perplexity stop using its content and trademarks without permission. According to the lawsuit, Perplexity did not respond.

Perplexity spokesperson Jesse Dwyer responded to the lawsuit with a brief statement: "You cannot copyright facts."

A Growing Legal Problem for Perplexity

CNN joins a significant and expanding list of organisations suing Perplexity for copyright infringement. The New York Times, Encyclopedia Britannica, Merriam-Webster, News Corp, Amazon, and Reddit have all filed separate legal actions against the company. The cumulative weight of these cases represents a serious legal and reputational challenge for Perplexity as it attempts to scale its AI search and browser products commercially.

What It Means for AI and Media Globally

The CNN lawsuit is part of a broader reckoning between the AI industry and the media organisations whose content has been used to train and power AI products. For Nigerian media companies and journalists, the outcome of these cases has direct relevance. If courts establish that AI companies must licence or compensate content creators for the material their tools reproduce, the precedent would apply globally and could eventually affect how AI tools interact with African news content in ways that generate compensation rather than simply consuming it.
