The Department of Justice is reportedly investigating Andreessen Horowitz over a board-seat arrangement that may violate a 112-year-old antitrust law rarely applied to venture capital.

At the center are two a16z partners: Ben Horowitz sits on Databricks‘ board and Martin Casado on Fivetran‘s.

The two companies were not direct competitors when a16z first invested, but they have since expanded into overlapping markets.

The probe, said to have been running for almost a year, highlights a fundamental question for venture firms: how do you manage board seats when portfolio companies’ boundaries keep shifting?

The episode discusses this and other week’s headlines, including Stripe paying $7.

5 billion for AI model router OpenRouter, with the hosts noting the acquisition is more about economics than the “singularity.

” They also cover AI companies caught in the middle as OpenAI, Anthropic, and Nvidia pull ahead; Rivian spinout Also raising $150 million to scale its autonomous vehicle bet; Uber’s new delivery partnership with drone company Zipline and what it signals for other autonomous startups relying on Uber; and whether Wispr‘s $280 million raise at a $2 billion valuation marks peak pricing for AI dictation apps.

The conversation frames the DOJ investigation as a potential shift in how regulators treat board level conflicts in venture capital, especially as portfolio companies grow into new markets and become indirect competitors.

No conclusions or legal judgments are offered in the summary, but the implications for governance and antitrust exposure are drawn directly from the podcast’s framing.
