Justice Department Probes Andreessen Horowitz Board Roles at Rival AI Companies

The U.S. Justice Department is investigating whether Andreessen Horowitz investment partners are improperly sitting on the boards of competing artificial intelligence companies, a practice that could raise antitrust concerns. The probe reportedly centers on board roles tied to Databricks and Fivetran, where Andreessen Horowitz co-founder Ben Horowitz and partner Martin Casado have served as directors. The case matters because regulators have warned that overlapping board seats among rivals can reduce competition and encourage the sharing of sensitive information in a fast-growing AI market. It is still a preliminary investigation, and no charges or final decisions have been announced.
