US Department of Justice launches antitrust investigation against venture capital giant a16z

According to Bloomberg, according to Bloomberg, the US Department of Justice is launching an antitrust investigation against Andreessen Horowitz (a16z), the top venture capital in Silicon Valley, focusing on the fact that its partner also serves as a director at several competing AI companies — co-founder Ben Horowitz is the director of Databricks, and partner Martin Casado is the director of Fivetran. The two companies compete in the field of data processing.

Casado also previously served as a director at dbt labs (acquired by Fivetran in June). The investigation, which has continued for almost a year, began with an antitrust review of Fivetran's acquisition of dbt labs. Although the acquisition was unconditionally approved, the investigation into the position of director continues. Such investigations usually end in the resignation of a director. a16z has a close relationship with the Trump administration. The two founders donated millions of dollars to the Trump campaign in 2024 and successfully promoted the weakening of the security fence on AI policies. a16z has assets under management of $90 billion and recently raised $15 billion in funds, with portfolios including SpaceX, OpenAI, and Cursor.
