Insurer Sues OpenAI Over Unauthorized Legal Practice

Nippon Life Insurance Company of America sued OpenAI in federal court in Chicago on Mar. 11, 2026, alleging ChatGPT encouraged a former disability claimant to reopen a settled case and drafted baseless motions that flooded the court. The insurer says the filings cost about $300,000 and seeks $300,000 in compensatory plus $10 million punitive damages, alleging violation of Illinois' unauthorized-practice-of-law ban; OpenAI calls the suit meritless.
