DOJ Probe Targets Andreessen Horowitz Board Seats
The U.S. Department of Justice has been investigating Andreessen Horowitz’s board-seat arrangements for nearly a year, according to Bloomberg and TechCrunch, examining whether partners serving on boards of companies that later compete violates Section 8 of the Clayton Act — a rarely used antitrust provision. The probe focuses on Ben Horowitz’s seat at Databricks (valued at about $190 billion) and Martin Casado’s seat at Fivetran (which combined with dbt Labs in June). TechCrunch’s Equity hosts and several VCs expressed puzzlement about the probe’s priority, duration, and the firm’s relative silence, noting possible political context. Observers warn enforcement could force investors to relinquish seats, adopt “Chinese wall” firewalls, or otherwise change venture governance, potentially using a16z as an example that influences smaller firms.
A DOJ probe invoking Section 8 of the Clayton Act could set precedent affecting VC governance, board-seat value, and how firms manage portfolio conflicts across the tech sector.

Ex‑a16z Partner Slams VCs for 'Political Infiltration' in AI
John O’Farrell, a former general partner at Andreessen Horowitz who resigned in 2025, published an op-ed criticizing what he called an attempted "political infiltration" by parts of the AI industry. O’Farrell singled out the PAC Leading the Future — whose backers include Andreessen Horowitz, OpenAI co-founder Greg Brockman, Palantir co-founder Joe Lonsdale, SV Angel founder Ron Conway and AI company Perplexity — and said it had raised over $125 million to influence politicians on AI policy. The piece warns that large political spending by wealthy tech investors risks a backlash and undermines trust, and argues the industry should engage constructively on regulation rather than trying to silence debate. The article also notes recent context: President Donald Trump signed an AI executive order in June 2026 that asks companies to voluntarily provide models for government assessment.
