The U.S. Department of Justice is investigating Andreessen Horowitz regarding partners serving on the boards of competing companies. The probe centers on whether the venture capital firm violated federal antitrust laws through overlapping board positions at data infrastructure rivals Databricks and Fivetran.

Andreessen Horowitz partner Ben Horowitz serves on the board of Databricks. Andreessen Horowitz partner Martin Casado serves on the board of Fivetran. Databricks and Fivetran are currently competitors in the data pipeline and application connector market. However, Databricks and Fivetran were not direct competitors when Andreessen Horowitz initially invested in them.

Databricks announced $5 billion in funding at a $190 billion valuation in August 2026. Andreessen Horowitz had $90 billion in assets under management as of January 2026. The firm recently raised a $15 billion fund.

Timeline

Fivetran acquired dbt Labs in June 2026.

What's New

Section 8 of the Clayton Act prohibits one person from serving as a director or officer of two competing corporations if each corporation has capital, surplus, and undivided profits aggregating more than $10,000,000. Spokespeople for Databricks and the U.S. Department of Justice declined to comment on the investigation. Spokespeople for Andreessen Horowitz and Fivetran did not respond to requests for comment.

The U.S. Department of Justice reviewed the Fivetran-dbt Labs merger and cleared it unconditionally. Andreessen Horowitz recently raised a $15 billion fund. Martin Casado previously served on the board of dbt Labs prior to its acquisition by Fivetran.

Why It Matters

The investigation tests the application of century-old antitrust statutes to modern venture capital structures where firms often hold seats across multiple portfolio companies. Section 8 of the Clayton Act was designed to prevent anticompetitive coordination between rival corporations through shared leadership, but its enforcement in the context of minority investor board appointments remains a complex legal question.

The scale of the entities involved demonstrates the potential impact of any regulatory action. With Databricks valued at $190 billion and Andreessen Horowitz managing tens of billions in assets, the outcome could influence how venture capital firms structure their governance roles in competing technology sectors. The unconditional clearance of the Fivetran-dbt Labs merger adds another layer to the regulatory picture, raising questions about how agencies evaluate competition in rapidly consolidating data markets.
