The United States Department of Justice (DOJ) has called Nick Turley, head of product at OpenAI’s ChatGPT, to testify in its antitrust case against Google, following a 2024 ruling that identified Google as a monopoly in search.

Although Google is appealing the decision, the DOJ is exploring potential remedies, including forcing a sale of Chrome or restricting new browsers.

Turley is expected to testify on the role of generative AI in search, data-sharing, and market access.

Google has subpoenaed OpenAI for documents, including those before ChatGPT’s 2022 launch, but OpenAI is contesting the request as excessive.

A court intervention is being sought to limit Google’s demands.

No comments have been made by the involved parties, and the testimony date is still pending.
