Chicago Tribune vs. Perplexity AI: The Copyright Battle Shaping the Future of News and AI

The Chicago Tribune’s lawsuit against Perplexity AI isn’t just another copyright skirmish—it’s a landmark fight that could redefine how AI interacts with journalism and intellectual property. As AI-powered search and summarization engines become more sophisticated, the boundaries between fair use, scraping, and outright content theft are blurring faster than ever.

Chicago Tribune sues Perplexity AI over copyright infringement

Let’s dig into why this case matters, what most people might miss, and what it signals for the future of AI, newsrooms, and digital copyright law.

Why This Matters

  • Sets a legal precedent for AI and news media relations: If the courts side with the Tribune, it could force AI companies to completely rethink how they access and use news content.
  • Puts Retrieval Augmented Generation (RAG) under the microscope: RAG is sold as a solution to AI ‘hallucinations’ by relying on real sources. But if those sources are scraped without consent, the tech could be legally dead on arrival.
  • Impacts paywalled journalism’s business model: If AI tools can bypass paywalls and summarize premium content, what’s left for publishers?

What Most People Miss

  • It’s not just about training data: While much attention is on AI models being trained on copyrighted material, this lawsuit tackles how AI uses and distributes content after training—especially via RAG systems and browsers like Perplexity’s Comet.
  • Multiple lawsuits, one core issue: The Tribune and its parent company are involved in several lawsuits against OpenAI, Microsoft, and others. The broader industry is watching to see if courts will finally clarify what counts as copyright infringement in the AI age.
  • Big Tech is nervous: Amazon’s legal threats, lawsuits from Reddit and Dow Jones, and the general flurry of court activity show that even the biggest players see danger in unchecked AI content scraping.

Key Takeaways

  • AI-powered summarization tools are on thin legal ice—especially when they bypass paywalls and reproduce content verbatim.
  • Retrieval Augmented Generation (RAG) may not be the safe harbor AI firms hope for if it depends on unauthorized content scraping.
  • News publishers are increasingly banding together to defend their content and revenue streams, potentially leading to new licensing deals or industry-wide standards for AI access.

Industry Context & Comparisons

  • RAG vs. Model Training Lawsuits: Most lawsuits focus on model training, but RAG is about real-time use of live content. This distinction could force courts to draw new lines around fair use and copyright in the AI era.
  • The Paywall Dilemma: If AI can simply crawl and summarize content behind paywalls, publishers may need to invest in more sophisticated anti-bot tech or seek legislative protection—much like the music industry did in the Napster era.
  • Precedent from Related Cases: The New York Times’ lawsuit against OpenAI, and Reddit’s and Dow Jones’ actions against Perplexity, all underscore a growing consensus: Newsrooms want a seat at the AI table—and fair compensation.

Pros and Cons Analysis

  • Pros (for AI companies):
    • Delivers users more accurate, real-time information
    • Limits misinformation by referencing real sources
  • Cons (for publishers):
    • Loss of subscription and ad revenue
    • Potential erosion of journalism’s value proposition

The Bottom Line

The Chicago Tribune v. Perplexity case is a bellwether for the entire digital news and AI landscape. Expect a wave of similar lawsuits—and perhaps even new laws—as publishers and AI developers wrestle for control over the future of information. The outcome? It could either spur collaboration (think licensing deals) or further fragment the digital content ecosystem with walled gardens and lawsuits galore.

Timeline of Recent Events

  • April 2024: Tribune and other publishers sue OpenAI and Microsoft.
  • October 2025: Reddit sues Perplexity for scraping user posts.
  • November 2025: More publishers join the lawsuit against OpenAI and Microsoft.
  • December 2025: Chicago Tribune files suit against Perplexity, focusing on RAG and paywall circumvention.

Action Steps for Publishers & AI Companies

  • Publishers: Audit your paywalls and bot defenses. Consider proactive licensing discussions with AI firms.
  • AI companies: Reexamine your data sourcing policies. Transparency and partnerships might be the only sustainable path forward.
