Andreessen Horowitz Faces Justice Department Antitrust Scrutiny Over AI Board Seats

The inquiry centers in part on Databricks Inc. and Fivetran Inc., two data technology companies backed by Andreessen Horowitz, according to people familiar with the matter cited by Bloomberg. The people spoke on condition of anonymity because the investigation is confidential.

Andreessen Horowitz co-founder Ben Horowitz sits on Databricks’ board, while firm partner Martin Casado serves as a director of Fivetran, according to Bloomberg. The companies operate in the market for technology that allows businesses to gather, manage and analyze large volumes of data, an increasingly important part of the infrastructure supporting artificial intelligence.

Casado previously served on the board of dbt Labs, another company operating in the data sector. Fivetran acquired dbt Labs in June after the Justice Department conducted a review lasting several months, Bloomberg reported. Regulators ultimately allowed that transaction to proceed without imposing conditions.

The broader investigation involving Andreessen Horowitz began roughly a year ago, around the time of the merger review, and remained active after the Fivetran-dbt Labs transaction was completed, according to Bloomberg’s reporting.

Representatives for the Justice Department and Databricks declined to comment to Bloomberg. Andreessen Horowitz and Fivetran did not respond to Bloomberg’s requests for comment.

The inquiry highlights renewed attention to a longstanding provision of U.S. antitrust law restricting so-called interlocking directorates, arrangements in which the same person or representatives of the same investment organization hold board positions at companies that compete with one another.

Such cases can often be resolved through changes in board representation rather than litigation. During the Biden administration, directors left roughly a dozen corporate boards, including at Live Nation Entertainment Inc., following Justice Department scrutiny of potential conflicts involving competing businesses, according to Bloomberg.

The Andreessen Horowitz investigation also comes as the venture capital firm has developed significant influence in Washington, particularly on technology and artificial intelligence policy.

Marc Andreessen and Ben Horowitz, the firm’s co-founders, each contributed millions of dollars in 2024 to a political group supporting Donald Trump during his presidential campaign, Bloomberg previously reported. Andreessen Horowitz has since emerged as an influential participant in debates over federal AI policy and has advocated for a lighter regulatory approach to the rapidly developing technology.

Bloomberg has reported that the firm successfully pressed the Trump administration to eliminate a number of AI safety restrictions. The firm’s political giving, however, has not been exclusively Republican. Later in 2024, Horowitz contributed $2.5 million to a super PAC supporting Democratic presidential nominee Kamala Harris, according to a Federal Election Commission filing cited in the source material.

The Justice Department investigation therefore places one of Silicon Valley’s most prominent venture investors under antitrust scrutiny at a time when Andreessen Horowitz has both expanded its exposure to AI companies and strengthened its relationships with policymakers.

The existence of an investigation does not establish that Andreessen Horowitz, its partners or its portfolio companies violated antitrust law, and Bloomberg reported no enforcement action resulting from the inquiry. The Justice Department’s review of the Fivetran-dbt Labs acquisition ended without conditions.
