The Department of Justice and the Federal Trade Commission are reportedly attempting to determine which agency should oversee an antitrust investigation of ChatGPT developer OpenAI and its relationship with Microsoft.

The two federal agencies have been in talks for months about which of them should review the matter, according to Politico. Neither agency appears keen to release their jurisdiction over the matter, people involved in the matter claim, a point of tension that would need to be resolved before either can investigate Microsoft’s $10 billion investment in the artificial intelligence developer. The potential inquiry would be a step forward for FTC Chairwoman Lina Khan and DOJ Assistant Attorney General Jonathan Kanter, who both are advocates for breaking up Big Tech companies.
