The U.S. Department of Justice and the U.S. Federal Trade Commission (FTC) are in deep discussions about which agency could investigate OpenAI on antitrust grounds, including ChatGPT's creators and Microsoft's (MSFT. O). A few months ago, the FTC began negotiations with the Justice Department to determine who would review the matter, according to three people familiar with the matter. But neither agency is prepared to relinquish jurisdiction, which needs to be resolved before the U.S. government intervenes in the partnership between the two companies, people familiar with the matter said. Over the past few years, Microsoft has poured billions of dollars into OpenAI. OpenAI is leveraging Microsoft's vast computing resources to develop its own technology, and Microsoft is integrating OpenAI's services into its core business, including the Bing search engine. Given the speed at which the technology is evolving, the agencies must reach a solution as soon as possible, some people familiar with the matter said.
