DOJ Probes Andreessen Horowitz Over AI Board Conflicts
The Justice Department opened an antitrust investigation into Andreessen Horowitz roughly a year ago. The probe focuses on whether its partners improperly serve on boards of competing AI companies.
- Co-founder Ben Horowitz sits on the board of Databricks, valued at $190 billion.
- Partner Martin Casado serves on the board of Fivetran, a Databricks competitor.
- $90 billion in assets under management makes Andreessen Horowitz one of the largest venture capital firms.
- Resolving such probes typically requires directors to resign from one competing board.
Why it matters: The investigation applies a rarely used provision of the Clayton Act of 1914, which bars individuals or companies from sitting on boards of directly competing firms.
- Under the Biden DOJ, more than a dozen directors left boards to resolve similar concerns.
- Andreessen Horowitz has closely aligned itself with the Trump administration on AI policy, successfully pressing to remove safety guardrails on the technology, Bloomberg has reported.
How 6 sources split on this story
Where they split: Coverage divides on whether the probe signals the Trump DOJ acting independently of political allies or represents a limited, procedural carryover from Biden-era enforcement.
Center coverage, 3 sources: The center frames the probe as a notable tension between the Trump administration's deregulatory stance and its willingness to scrutinize a close political ally.
Right coverage, 2 sources: The right emphasizes the political connections of the firm's founders and frames the investigation as a continuation of Biden-era antitrust enforcement rather than a break from it.
What’s next: The DOJ has made no final decisions; the case could close without action.
- If violations are found, Horowitz or Casado could be required to leave one board.
- Whether the Trump DOJ will pursue the investigation aggressively given Andreessen Horowitz's political ties remains unclear.
- It is unresolved whether the 1914 law applies clearly to a venture capital firm — rather than individual directors — sitting on competing boards.
- What consequences, if any, a board resignation would have for Databricks' planned IPO is not yet known.
