The U.S. Justice Department is investigating venture capital firm Andreessen Horowitz as part of an antitrust inquiry tied to artificial intelligence company board representation. Bloomberg reports that the probe focuses on whether partners at the firm may be improperly serving on the boards of competing AI companies, based on people familiar with the matter.

According to the outlets, the question centers on potential conflicts that could arise when investors hold governance roles across rivals in the same market. The Next Web, citing Bloomberg’s reporting, says the investigation appears to have been underway for nearly a year. Neither outlet provides specific company targets, named board directors, or details on any enforcement outcome, as the reporting is attributed to sources and not public filings or a formal statement in the available excerpts.
