AI-Written Federal Filings Jumped to 18% in 2026 as OpenAI Fights Nippon Life Suit

Summary
A new study of 4.5 million federal civil cases found self-represented lawsuits rose to 16.8% in 2025 from 11% in 2022, with AI-flagged filings climbing from 1% in 2023 to 18% in 2026.
Judges say chatbots are helping litigants draft clearer pleadings and file more cases, even as hallucinated citations and bad legal advice create new risks and extra screening work.
Win rates have not improved for people without lawyers, the study found, underscoring that drafting is only one part of litigation and that AI does not replace legal strategy or procedure.
Courts are already split on whether chatbot exchanges deserve legal protection, with federal rulings in Michigan, New York and Colorado reaching different conclusions on privilege and work product.
That uncertainty is feeding lawsuits and legislation: Nippon Life sued OpenAI in March over alleged unauthorized legal practice, OpenAI moved to dismiss in May, and New York and Congress are weighing curbs on AI posing as lawyers.
