Publishers Sue Meta, Zuckerberg in Landmark Llama AI Copyright Case; Shares Drop 1.4% to $601.74

Five major publishers—Elsevier, Cengage, Hachette, Macmillan, McGraw Hill—and author Scott Turow sued Meta Platforms and CEO Mark Zuckerberg on May 5, 2026, in Manhattan federal court, alleging the company pirated millions of copyrighted books and journals to train Llama AI models while stripping copyright data. Coverage escalated through the day, highlighting class-action claims, a jury trial demand, and Anthropic's $1.5 billion settlement precedent, with Meta vowing an aggressive fair-use defense. META shares fell 1.4% to $601.74 by 16:44 amid risks of landmark litigation costs, damages, and regulatory scrutiny.
