Wilson Sonsini Obtains Summary Judgment for OpenAI in Defamation Lawsuit
On May 19, 2025, Wilson Sonsini secured summary judgment for OpenAI in the first-ever case charging a generative AI company with defamation based on an AI output. The plaintiff, Mark Walters, is a nationally prominent gun rights advocate and radio show host. His defamation claim arose from a journalist's use of ChatGPT in May 2023, where the journalist asked ChatGPT to read and summarize a legal complaint hosted on the web. ChatGPT incorrectly summarized the lawsuit as involving allegations of embezzlement against Walters.
