CNN has joined the growing list of publishers challenging AI firms over how they use journalism, filing a federal lawsuit against Perplexity AI that could influence how AI-powered search companies access and distribute news content.
The complaint, filed in New York, accuses Perplexity of using CNN articles, videos and images without authorization to support its AI answer engine. CNN alleges the startup reproduced or closely paraphrased thousands of pieces of content and delivered competing summaries and responses to users, including material that was originally placed behind a paywall.
The case adds pressure to a core unresolved issue in generative AI: whether companies building AI-driven search systems can freely scrape and summarize online journalism under fair use protections, or whether publishers must be compensated through licensing agreements.
Perplexity rejected CNN’s claims. Company spokesperson Jesse Dwyer responded publicly by stating that facts themselves are not protected by copyright law.
CNN is seeking monetary damages and a court order that would prevent Perplexity from continuing to use its intellectual property without permission. The lawsuit argues that large AI firms are benefiting financially from reporting they did not fund or produce, while potentially reducing traffic and subscription revenue for publishers.
The conflict between media companies and AI startups whose products depend heavily on access to high-quality written content has escalated over the last few years. Since the launch of OpenAI’s ChatGPT in late 2022, publishers and rights holders have challenged the way AI systems collect and generate text from copyrighted material.
Perplexity has become a particularly visible target because it positions itself as an alternative to conventional web search through AI-generated answers. Rather than presenting users with a list of links, the platform generates concise responses synthesized from online sources. Publishers argue that this approach risks displacing the original news providers that financed the reporting.
CNN’s lawsuit follows similar legal actions brought by The New York Times, Dow Jones, Reddit and other content owners. Encyclopedia Britannica, Merriam-Webster and News Corp have also taken legal action against Perplexity over alleged unauthorized use of content.
The filing additionally reveals that CNN and Perplexity had explored a commercial arrangement in 2025 involving CNN content within Perplexity’s subscription offerings. According to the complaint, negotiations collapsed after the companies failed to agree on limits governing how CNN material would appear in AI-generated answers. CNN later demanded that Perplexity stop using its reporting and trademarks, the suit claims.
Valuations at Stake
Investors and tech firms are closely watching whether courts determine that retrieval-augmented generation systems require licensing agreements with publishers. A ruling against AI search companies could significantly alter operating costs for startups that currently rely on large-scale web scraping and summarization.
Perplexity has reportedly achieved valuations ranging from $18 billion to $20 billion during recent fundraising activity. Additional licensing requirements or litigation costs could force Perplexity and other AI firms to rethink margins and partnerships with media organizations.
Several publishers have already shifted toward negotiated agreements rather than legal action. Major news organizations have signed licensing partnerships with AI developers and large tech companies in an effort to generate revenue while maintaining visibility inside AI systems. Overall, media companies appear focused not only on damages, but on establishing leverage over how AI platforms obtain and monetize information.
