The U.S. Department of Justice is investigating whether venture capital giant Andreessen Horowitz has partners improperly serving on the boards of competing artificial intelligence companies, according to a Bloomberg report.
The probe centers on whether a16z co-founder Ben Horowitz, who sits on the board of data analytics firm Databricks, and partner Martin Casado, a board member at Fivetran, are violating the Clayton Antitrust Act of 1914. That law prohibits a single individual from simultaneously serving as a director or officer of two corporations that compete with each other.
Competing Data Infrastructure Firms
Both Databricks and Fivetran operate in the data infrastructure space, providing tools that help businesses collect, organize, and analyze large volumes of data. The two companies compete for enterprise customers in an increasingly lucrative market, making the question of shared board oversight a matter of direct competitive concern.
The investigation, which has not been previously reported, is nearly a year old. It was opened around the same time the DOJ began reviewing Fivetran’s acquisition of dbt Labs, a deal first announced in October. Casado had previously served on the dbt Labs board before that company was absorbed into Fivetran in June. According to Investing.com, the DOJ ultimately cleared the acquisition unconditionally, but the broader probe into board overlap has continued.
Antitrust Enforcement in AI
Resolving such investigations typically requires that a director step down from one of the competing boards. If a16z is forced to make that kind of concession, it would represent a significant rebuke for one of Silicon Valley’s most powerful firms and could set a precedent for how regulators oversee VC board representation in the AI sector.
The probe is notable given a16z’s close ties to the Trump administration. Co-founder Marc Andreessen has been a visible supporter of former President Donald Trump, and the firm’s portfolio spans some of the most prominent names in tech, including OpenAI, Anduril, SpaceX, and Cursor. The fact that the DOJ is pursuing the investigation despite those political connections suggests the agency is taking antitrust enforcement in AI seriously.
Implications for VC Governance
The case raises broader questions about how venture capital firms manage conflicts of interest when they invest heavily in competing companies. A16z has raised billions of dollars across multiple funds and maintains stakes in dozens of AI and data companies simultaneously. If regulators determine that board overlaps at competing firms constitute anticompetitive behavior, it could force sweeping changes in how VC firms allocate board seats across their portfolios.
The DOJ has been increasingly focused on competition issues in the AI industry. In 2024, a senior agency official confirmed the department was scrutinizing overlapping executives and directors at rival AI companies. The a16z investigation appears to be the most prominent case to emerge from that broader effort, and its outcome could reshape the relationship between venture capital and the companies it funds.
