The US Justice Department is investigating Andreessen Horowitz for a potential Clayton Act violation: cofounder Ben Horowitz sits on the Databricks board while partner Martin Casado sits on the Fivetran board — two competing AI data companies both backed by the firm.
Details
The US Department of Justice has opened an antitrust probe into venture capital firm Andreessen Horowitz over dual board representation at competing companies. According to Bloomberg, the probe centers on cofounder Ben Horowitz's seat on the Databricks board and partner Martin Casado's seat on the Fivetran board. Both are data infrastructure companies that help businesses collect, organize, and analyze data — and both are a16z portfolio companies. The Clayton Act prohibits directors from sitting on the boards of directly competing companies to prevent the sharing of sensitive competitive information. What makes this probe unusual is that the DOJ is reportedly targeting the firm itself, not just individual partners. The political dimension adds complexity: a16z's founders donated millions to a pro-Trump PAC and were active in pushing the Trump administration to roll back AI safety rules. The firm also holds major stakes in AI companies including OpenAI. A finding of liability could force a16z to relinquish board seats across its AI portfolio, with ripple effects on AI governance across companies it backs.
