DOJ Probes Andreessen Horowitz Over Partners Sitting on Competing AI Boards

The US Justice Department is conducting an antitrust investigation into venture capital firm Andreessen Horowitz. The probe focuses on whether the firm’s partners improperly hold board seats at competing AI data companies, specifically Databricks and Fivetran. This case stands out for targeting the firm itself under a century-old law banning ‘interlocking directorates.’

Key takeaways

• The DOJ is investigating Andreessen Horowitz for potential antitrust violations related to its partners’ board positions.
• The probe centers on partners sitting on the boards of competing data firms Databricks and Fivetran.
• The investigation uses a 1914 law against ‘interlocking directorates’ to prevent anti-competitive information sharing.
• It is unusual because it targets the VC firm directly, not just the individual directors.
• The firm’s significant political ties and influence add a complex dimension to the case.

The Core of the Antitrust Probe: Interlocking Directorates

The US Justice Department is investigating venture capital firm Andreessen Horowitz for a potential antitrust violation. The probe centers on whether the firm’s partners improperly sit on the boards of directly competing AI companies, specifically data firms Databricks and Fivetran.

Focus on Competing Data Firms

Cofounder Ben Horowitz sits on the Databricks board, and partner Martin Casado sits on the Fivetran board. Both companies are described as competitors in helping businesses collect, organize, and analyze data.

Legal Basis and Unusual Scope

The investigation is based on a 1914 law banning ‘interlocking directorates,’ which aims to prevent the exchange of sensitive information and weakening of competition between rivals. This case is notable because the probe targets the firm itself directly, not just the individuals, because several of its partners sit on competing boards.

Unusual Scope and Timing of the Investigation

What makes this case different is that the DOJ probe targets the venture capital firm Andreessen Horowitz itself, not just individuals. This is because several of its directors sit on competing boards, specifically with partners on the boards of both Databricks and Fivetran.

Timing Relative to Other Reviews

The nearly year-old investigation began around the same time the DOJ was reviewing Fivetran’s acquisition of dbt Labs. That merger was ultimately cleared without conditions after months of review.

Typical Case Outcomes

Historically, such cases over interlocking directorates typically end with directors stepping down from one of the competing boards. Under the Biden administration, the DOJ forced executive resignations in about a dozen similar cases.

Andreessen Horowitz’s Stakes and Political Context

With about $90 billion in assets under management, Andreessen Horowitz ranks among the world’s largest venture capital firms. The firm holds significant stakes in prominent AI companies, including OpenAI, SpaceX, and ElevenLabs.

Political Alignment and Influence

The firm’s ties to the second Trump administration add a political dimension to its operations. According to reports, Andreessen Horowitz has aligned itself closely with the White House. Its founders, Marc Andreessen and Ben Horowitz, donated millions to a pro-Trump group in 2024.

This alignment has reportedly translated into policy influence. The firm successfully pushed to roll back many AI safety rules, a move that benefits its own portfolio companies.
